Technology disrupts many jobs but it creates new jobs with more
efficiency and consistency to become the lifeline for the economic growth of
any country”.
In today’s internet-driven world, IR4.0 revolution is riding on the high
wave of technology and information. Consequently, many events are impacting our
lifestyle, health, relationships, productivity and efficiency. In such a
dynamic environment, you are required to do multi-tasking while dealing with
management, customers, vendors and business partners. You should be physically
and mentally fit to endure such a high-pressure environment and get affordable
healthcare when needed. Digital Technologies, Intelligent Sensors, and
Multi-Media intelligent devices are already supporting hospitals to provide
good healthcare. Emerging technologies like Artificial Intelligence (AI),
Machine Learning (ML), Drones, Robotics, Cloud Computing, Big Data, Internet of
Things (IoT) and 5G (future) are moving fast to reshape the work practices and
business processes of many industrial sectors. The demand for AI / ML systems
and skilled professionals to support AI/ML applications continues to rise.
During 2019, some industry analysts had estimated that the AI/ML Healthcare
market may reach $6.6 billion by 2021. Due to COVID-19 pandemic, these
estimates may be revised.
Machine Learning is a subset of AI where it can quickly access large
data from healthcare database to speedily process, diagnose and interpret
accurately. The outcome can assist the physicians to take the final decision.
ML is well suited for accurate and fast diagnostics, related to chronic
diseases.
Machine Learning (ML). ML is an efficient and very fast
computing system, interconnected with sensors, data channels and Big Data
system. ML can quickly learn and adapt to the designed model based on
healthcare data. ML follows adaptive technique through iterative processing for
quick learning. It diligently processes the received/retrieved healthcare data
to provide a consistent and accurate outcome. ML can also use data received
through multi-media devices like smartphones, in the form of text, image,
audio, video and graphics. ML is a highly progressive approach for the
precise, cost-effective and comprehensive diagnostics in most of the Clinical
Fields such as Oncology, Cardiology, Orthopaedic & Trauma, Urology,
Nephrology Plastic Surgery, Neurology, Endocrinology, Genetic Related Disorders
and other cases of Mental Health diseases.
Healthcare data. It is quite huge and of different formats /forms.
You need special software tools like Data Mining and ML to extract relevant
data and process for drawing an inference. All these methods are used to
extract target (labelled) data, and present that for processing and determining
patterns and relationships. This helps in decision- making.
Neural Networks (NN). NN as a part of the ML system attempts
to mimic the way the human brain tackles health problems. In this, ML uses
layers of interconnected units to infer relationships based on the observed
data of the patient and/ or the data retrieved from the database.
Natural Language Processor (NLP). NLP processor helps in processing
large amounts of natural language data (Voice and Text). NLP helps in natural
language operations, automated speech recognition and automatic conversion of
speech to text.
The popularity of ML. ML is related to
statistical data of patients/diseases, and can quickly process data using
high computing power and storage of Cloud Computing. ML processes the
data iteratively to draw timely and reliable outcome. By implementing ML
system, the Hospitals and Pathological Labs will acquire the ability to
continually predict changes in their processes/procedures and predict future
trends. The outcome of the ML system will be speedy. accurate and
unbiased to provide a patient-centric diagnosis. This will help them to update
their operations continuingly.
Indian National Strategy on ML for Healthcare. In 2015 India had
taken a very bold imitative “Digital India”. To give further impetus to its
digital economy, NITI Aayog (Planning Commission) of India had formulated
comprehensive guidelines in Jun 2018, for introducing AI, ML and Robotics in
various sectors, including healthcare. There is an acute shortage of doctors
and nurses in Indian hospitals. India has also an issue of long-distances
between its Primary Health Centers (PHCs) located in far-flung areas and
referral hospitals located say 200Kms -1000Kms away in cosmopolitan cities.
Tele-medicine using ML technology could mitigate this distance problem. ML
combined with the Internet of Medical Things (IoMT) will be the new mantra for
planning and providing quality healthcare at affordable cost and to a greater
satisfaction to the patients.
Indian Healthcare System. “Health is Wealth” is ever
true for any economy to grow for which it needs a healthy and skilled
workforce. Therefore, maintaining the good health of a nation is the prime
responsibility of every government. Healthcare relates to providing efficient
diagnostic facilities and appropriate treatment for the patients so that they
remain healthy to work at their full potential. In today’s era of technology
and fast mobile communications, we keep changing our lifestyle and habits
related to food, drinking, sleeping, and even social interaction. Likewise, our
work environment is also fast-changing, where we are doing less physical
exercise and eat fast/processed (trash) food, which lacks balanced nutrients.
Consequently, we are becoming more prone to many injuries, diseases, viruses
and Covid -19 like a pandemic.
Despite India’s rapid progress in many fields, and having good numbers
of medical colleges, it still has only a few senior/ experienced physicians in
tier 2 and tier 3 hospitals. The doctor on duty in a hospital has to depend on
a lab test and analysis report prepared by the lab technicians /junior doctors.
Duty doctor has little or no time to refer to a patient’s historical data or
any statistical information on similar medical cases of the past. The situation
is really poor in Indian government-run hospitals at district/tehsil/ division
level. In serious cases, PHCs located in a far-flung area, just transfer their
patients to higher-level hospitals or Research Institutes. However,
higher-level hospitals are often quite far away. which causes an undue delay in
treating the patient.
Patient Data Types. Patient’s data related to his/her
current and past ailment and data of patient’s relatives /family members and
other patients having suffered from similar disease can be speedily collated
and processed/interpreted by the ML system. The outcome is then presented to
the senior doctor to decide the final procedure/ treatment. Some common data
formats and the medium used for recording images and graphic data about
patients and which can be integrated into the ML system are listed below:
·
Patient personal details. Name, Unique ID (Addaar Card in India), Next
of Kin (NOK). Contact phone, address. Direct admission (D) or Transfer case (T)
from other hospitals.
·
Disease Data. Patient Name. hospital registration number, ward number,
bed number, date of admission, time of admission, age, gender, disease name and
code (WHO Code).
·
Medical Record Sheet. Handwritten case sheet or hand-held keypad for
on-line keying in digital data for each patient.
·
On-line monitoring in ICU. Health parameters like BP, Pulse-rate,
Heart-beat and body temperature.
·
Blood test data. Liver profile, Blood Sugar. Haemoglobin. Blood
count, Platelet Count. Cretin, Uric Acid
·
Heart Test. ECG, Angiography, Doppler Ultrasound test
·
Image Scans. X-Ray, Ultrasound Scans, Magnetic Resonance Imaging (MRI),
Computed Tomography (CT) Scan, Brain Scan.
·
Breast Cancer. Mimeograph Scan
·
Microscopic plates. These are sample data of Cancer, Tuberculosis, and
Viruses.
Sources of Healthcare data. Healthcare data mainly comes from
Research and Development Labs, physicians, hospitals/clinics, patients and
social media. It is also extracted from the database held on a chosen cloud.
Algorithm Development. The heart of the ML system is diligent
designing of the algorithm and its strict validation by a joint team of
experts. Algorithms for healthcare applications are more complex than those
used for other business applications. Healthcare algorithms are very carefully
developed by a highly skilled and multi-disciplinary team, having in-depth
medical knowledge and experience in high-end software development.
Software tools and Programming Language. To solve healthcare problems,
the project team uses a variety of software tools like TensorFlow, NumPy and
programming languages like Python and R. For maintaining the database,
the team may use MongoDB / MySql like database and Cloud-like AWS (Amazon),
Azure (Microsoft), IBM Cloud or Google Cloud. Software team uses numerical
methods to transform expressions/ equations (matrices, calculus and statistic)
into programmable expressions. Thereafter, Python and R like programming
languages are used for codification. Each developed algorithm is first
verified by the software team and then validated using test data, jointly by
healthcare experts and software team. The formulation, analysis, design
and statistical modelling, coding and testing and validation should be treated
as a Software Project Management, adopting Agile /Scrum like approach.
Algorithm Selection. Expert / the doctor must carefully select an
appropriate algorithm for the selected real-life healthcare problem.
Training of Computing Machine. ML training is an elementary but
laborious process like a mother teaching her small child by asking the child to
listen carefully – “what to do, when to do and how to do”. She even cautions
her child what not to do and make no further mistake. The child grasps the
mother’s instructions and faithfully tries to do as was told. If the child
makes a mistake, the mother corrects the child but warns him/her to be careful
in future. This cycle carries on iteratively to gain more knowledge and respond
to any emerging situation. The child also learns to choose alternative action
to deal with any new situation. This way the child progressively becomes
confident in his/her actions. The mother becomes confident that her child can
deal appropriately with any emerging situation. A similar concept is being
followed to train the ML system so that it could process the data faithfully,
speedily and diagnose the disease accurately.
Types of ML Training. The outcome of the ML system is the output
generated by a well-trained computer/ machine, clean data and validated
algorithm. A predictive algorithm will produce unbiased prediction based on the
data. ML system can be fully trained on various models and by using various
data-sets from the database and even actual patients. Different approaches for
ML system training, based on data structure, type, volume and complexity are:
·
Supervised Learning. (SL). It is human supervised learning by the
computing machine, based on known data-set attributes and data classification.
This data has labelled features that define the meaning of data. The machine is
trained using pre-processed examples, and the performance of the algorithms is
evaluated with known test data.
·
Unsupervised Learning (UL). It is an iterative process used for
analyzing data-set but without human intervention. UL is best suited when the
problem requires a huge amount of data coming
from social multi-media applications, such as Messenger, WhatsApp,
Twitter, Facebook or Telegram.
·
Reinforcement Learning (RL). RL is a behavioural learning a model where
the algorithm receives feedback from the analysis of the complex data and the
user (computer system) is progressively guided to the best outcome. ML
system learns through trial and error but provides a better outcome.
ML Applications in Healthcare. Applications of ML in healthcare is a
very vast subject and only general coverage has been given in this article.
Incidences of complex diseases are growing at an alarming rate. This is further
compounded due to large Volume, Variety and Velocity (V3) of
structured/unstructured data flowing through the internet on a 24x7
basis. Fortunately, this issue is mitigated by the availability of Cloud
Computing and Big Data technologies. Thus, ML can provide timely, affordable
and better healthcare services. ML is the most valuable resource for the
healthcare sector and support, many healthcare experts, senior
doctors/physicians and pathologists. Luckily, the healthcare sector has been an
early adopter of digital technology, optics, instrumentation, intelligent
sensors and robotics.
Application areas. ML is an integrated system of many computing
devices, data monitoring sensors, supporting high-speed data channels having
capability and capacity for data capture from multimedia devices like
smartphones/tablets. ML can process retrieved data at super speed, carry out
algorithm-based analysis across vast data related to patient/disease and even
suggest a treatment. Some areas where ML is best suited are briefly
indicated below: -
·
Healthcare data of patients and their relatives and various diseases is
too large to handle by traditional analytic techniques.
·
Past historical data of patients and diseases are too large and takes
too much time to retrieve from medical records (Paper/ Digital).
·
The urgency of the patient’s current and past data records
of chronic diseases like cancer, diabetes, tuberculosis, depression and
suggested treatment.
·
Rules/constraints and quantification of disease parameters is not easy
to translate.
·
Speed, Accuracy and Interpretation of the outcome are most important.
·
The large volume of structured/ unstructured data (Text, Voice, Image,
Graphics) related to patients is flowing through multi-media
Job Potential. During 2019, Frost & Sullivan a Research firm in the USA had
estimated that by 2021, AI /ML will generate nearly $6.7 billion in revenue in
the global healthcare market. Likewise, McKinsey has predicted that application
of Big Data, Cloud Computing and ML in the healthcare sector can generate
globally up to $100 billion annually. This will be possible due to the
availability of AI/ML, Robotics, Intelligent sensing devices, Cloud Computing,
Big Data enabling faster and more accurate decision-making. ML will also offer
new software tools for accurate, unbiased and timely prediction for supporting
physicians, and drug regulators. There are many ML applications in the
healthcare sector. Some of these are briefly given below:
·
Identifying Diseases and Diagnosis. With the rapid advancement in
computing, databases architectures, AI, Robotics, Internet of Medical Things
(IoMT), integration with 5G technologies and multi-media devices.
·
Medical Imaging Diagnosis. ML can quickly scan and interpret the
contents in the image. For this, ML has helped in developing a new
technology called Computer Vision (CV). One such Microsoft project “Inner Eye”
is becoming popular.
·
Radiotherapy. During image analysis, there can be many discrete
variables which can arise at any particular time. Some of these cannot be
easily modelled using complex mathematical equations. Google's DeepMind
Health is actively helping researchers to develop ML algorithms to accurately
differentiate between healthy and cancerous tissue. This will improve radiation
treatment.
·
Accurate detection of Breast Cancer. Breast cancer continues to be a
global serious health problem. As per WHO every single year, over 1.6 million
women are diagnosed with breast cancer and given treatment. Despite improved
treatments, there are globally round 500,000 deaths due to breast
cancer every year. Applying ML to mammography screening will help very many
women for timely detection and appropriate treatment of breast cancer.
·
Early prediction of epidemic /virus. AI and ML-based technologies are
being actively used for monitoring and predicting epidemics around the world.
Today, scientists have access to a large amount of data collected as satellite
imageries; real-time drone-based data, social multi-media updates and website
information. All such data can be quickly collated to predict outbreaks of
infectious diseases. Such predictions can be very useful for the WHO to give
timely advice to various countries.
·
Data Sharing. With the easy availability of low-cost multi-media
portable devices, patient’s data can be speedily passed on to a central
database from remote locations.
·
Discovery of New Drugs. With the worldwide spread of the deadly virus “COVID
19”, the urgency to research and find a suitable vaccine to cure corona
affected patients have been on war-footing since Jan 2020. A lot of research is
on in many labs of hospitals / medical institutes/universities of USA, China,
UK, France, Japan South Korea, Israel and India. Discovery and testing of
a new drug for human use take a few years. However, to find new treatment
against COVID 19, collaborative efforts at WHO level are on and the new drug
may be available by early 2021.
·
Drug Research and Manufacturing. ML is already playing an
important role in Research & Development of next-generation sequencing and
precision medicine. This can help in finding alternative therapy of serious
diseases. ML-based software libraries, cloud-based database and fast
computation through cloud computing are now available for accelerate drug
research work.
·
New Treatment Options. ML the system with real-time patient data
available from different healthcare systems of multiple states /countries can
increase the efficacy of new treatment options.
·
Remote healthcare. The traditional e-healthcare models based on
Information and Communication Technology (ICT), linking PHCs located in rural
areas are not adequate to face the challenge of the ever-growing population and
onslaught by many deadly diseases and viruses. ICT based healthcare model
is required to be integrated into ML systems which will be soon available at
main hospitals and research institutes. ML system plays an important role in
acquisition, management and exchange of medical information of the patient
located in remote/rural area. This will make it possible to follow the
treatment/ procedure without moving the patient.
· TeleHealth. ML has no restriction of the geographical boundary of a
district/state/region/country. Thus, ML can mitigate the long-distance the
problem of rural PHCs to seek reference from far off referral hospitals and buy
medicine locally. Thus, ML will help in providing tale- medicines to a much
larger population.
·
Mental Healthcare. Mental health is an indicator of emotional,
psychological, behavioural and social well-being of an individual. It
determines how an individual thinks, feels and handles emerging situations. His
/her productivity. job progress and family happiness are linked to mental
wellbeing. Mental health is an important factor in the various stages of our
life starting from childhood to adulthood, women’s pregnancy and old-age.
Biological changes in the chemistry of brain functioning lead to hypertension,
stress, anxiety and depression. These ailments affect the productivity of
individuals, the profitability of the organizations and economy of the country.
Therefore, early detection of the onset of mental illness, providing timely and
appropriate treatment are very essential. Some issues where ML can
support the psychiatrist are:
§ Mental
disorders. These include Depression, Anxiety, Bipolar Disorder, Dementia,
and other Psychoses. As per WHO global estimates in 2019, cases of mental
illness were - Depression- 264 million, Bipolar disorder – 45
million, other psychoses-20 million and Dementia -50 million. The numbers
of mental disorders continue to rise rapidly and it is impacting human
wellness, social relationships, human productivity and national economy
worldwide. ML can be effectively used for screening patients and assessing the
onset and symptom trajectory of the mental illness.
§ Detecting causes of
Mental Disorders. Mental disorders may be due to the inability to manage one's
thoughts, emotions, behaviour and interaction with others. Mental disorder is
caused by biological, social, cultural, economic, political, and environmental
factors. Healthcare systems, particularly in developing and
under-developed countries have not yet responded suitably to manage their
mental health issues. It is envisaged that ML when fully integrated with the
domestic healthcare system, could mitigate most of the issues and provide
affordable mental healthcare services.
§ Status in India.
National Institute of Mental Health and Neurosciences ( NIMHANS) at Bengaluru
and New Delhi are already collaborating with local IIIT/ IIT in
planning ML-based research and applications for diagnosing and treating
Depression, Hypertension and Anxiety.
Institutes/ Companies engaged in ML Implementation. ML is playing
a major role in Clinical Diagnostics, Patient Information System (PIS), early
detection of disease, and faster decision making by the healthcare department
/organizations/hospitals. There are several institutes/companies in the USA
which are actively engaged in ML related activities. These organizations have
the potential to offer jobs for professionals with the latest ML related skills
sets. Likewise, there are drug manufactures and drug research organizations in
technology-oriented countries like USA, UK, Germany, France, Sweden, Canada
Japan, Israel, Austria and some emerging economies like India, which are giving
a boost to ML use for healthcare.
Advantage of ML for Healthcare Services. Earlier doctors
/scientists were using super-computers for analyzing data related to genetic
disorders for various diseases of patients. Many times patient’s past records
were not available for drawing any co-relation. With the availability of
Cloud Computing, Big Data, Analytics and Multimedia Analytic, ML
has now got the ability to quickly retrieve any data and process it at super fast speed. This has given a new dimension for genetic analysis and
disease interpretation. Some of the major advantages of using ML for healthcare
are given in succeeding paragraphs.
·
ML performance is consistent since the machine does not get fatigued
like human beings.
·
ML uses the experience of many senior/ experienced doctors and technical
support staff and has a higher probability to be accurate in its prediction.
·
Unbiased, speedy and accurate processing of patient data helps in
quick interpretation and timely decision-making.
·
ML can help to discover what genes are involved in specific diseases and
also provide a patient’s genetic information.
·

optimal rescheduling of labs testing and procedures in operations theatres.
·
ML can monitor bed occupancy in the number of ICUs and display likely
bed vacancy.
·
Detect unexpected behaviour of patients and overcome their
depression/anxiety.
·
Sudden quitting of specialist does not affect healthcare services
·
Early detection of disease, its symptoms and causes can help in better
administration and control of any epidemic.
·
Shortages of senior doctors/ technicians in remotely located healthcare
centres/hospitals can be mitigated by on-line medical advice and
medicine.
Issues and concerns about ML. Treating patients using ML is a
more delicate procedure than testing ML for an e-commerce application. Indeed,
acceptance of ML for healthcare will always be a big challenge due to human
emotions, technical constraints and regulatory compliance. The software and
algorithm resident in the ML computer will process inputs and generate a
program which produces output. This process goes on iteratively
until the outcome is acceptable.
The availability of Big Data supported by the huge computing power of
Cloud Computing has given big momentum to ML for decision-making and
administration of healthcare services. The output of ML is entirely
dependent on the data and algorithm and any change in data will change the
outcome. Despite many advantages of ML, some lingering issues for ML use in the
healthcare sector are briefly listed below:
·
Human Touch. Some patients feel that machine-based diagnostic lacks the
human touch. They believe that a doctor is always sympathetic and cares for
his/her patients.
·
Loss of Jobs. Many people in the healthcare sector fear that ML
will take away their jobs. They resist ML implementation and avoid learning ML
skills even if such free training is organized within their own campus.
·
Lack of trust in the Outcome. In ML environment, it is the algorithm
which determines how to process patient’s data and interpret its outcome. They
think decision-maker is a black-box and not an able doctor.
·
Data Reliability. Although ML algorithms process input data in an
iterative way to produce predictable and accurate outputs based on the data
patterns yet there are doubts about the reliability of the data and the
outcome.
·
Lack of standards. Although ML has been around for a few years yet there
are no universally accepted standards to improve its universal
acceptability.
·
Safety and security of data. Some patients have fear of
cyber hackers sabotaging ML process to produce wrong
outcome.
·
Ethical implications. Patients are worried about misuse
of their health data by the multimedia service providers.
Future ML Applications. There are lots of
opportunities for further research in ML and its integration with other
technologies to benefit the healthcare sector. Some areas are indicated below:
·
Great scope to develop strong Decision Support (DSS) system to help
doctors and administrators of healthcare services.
·
Optimizing ML capability in managing medical claims, detecting fraud,
improving clinical workflows, and predicting hospital-acquired infections.
·
Research for improving response time and ensuring better patient
satisfaction.
·
There's a big scope for using NLP methods to study patients’ emotions
and behaviour.
·
Multi-Media Analytic. Integration of patient information (text, image,
audio, video, graphics) coming through multimedia and the Internet.
·
DNA sequencing. ML can help to apply super imaging technique and
Natural Language Processing (NLP) to classify DNA sequencing.
·
Cancer Detection. ML can help to detect cancer based on the cell
information provided by the Support Vector Machine (SVM)
·
Drug Discovery. ML can help Support Vector Regression (SVR) for
disease-drug diagnostics and drug discovery.
·
Detect Mental Disorders. Use ML algorithms for early detection of
mental disorders and suggested treatment.
·
Detecting Diabetes. ML can assist to analyze data like blood
pressure, heart rate, and cholesterol level tests using Deep Neural
Networks (DNN) for detecting diabetes.
·
Cloud Computing and Big Data Technologies. Multimedia information
comes like a flood and needs cloud computing and Big Data support. These need
integration with ML.
·
5G Network. It is expected that 5G mobile networks will be available by
mid-2021 to replace existing 4G networks. This will pave the way for ML drawing
synergy from IoT / IoMT.
·
Cyber Security. During 2018-2019, some terrorist organizations/hackers
had succeeded to disrupt operations of hospitals/banks/airports in many
countries. Healthcare organizations/hospitals and drug development labs are
equally vulnerable and would require foolproof
cybersecurity.
·
Patient data privacy. This is a sensitive issue since multimedia users
and service providers could misuse patient health data. There has to be a
strong policy to protect a patient’s health data.
ML Jobs Opportunities. Today, a career in AI /ML field
is most lucrative and highly paid for which both new and experienced
professionals of IT/ Computing software and Mathematics/ Statistics fields
are looking for an opportunity to join the AI/ML related jobs.
All such professionals who have an analytical mind and creative thinking
can have career transition into ML area. However, the ML job is not simple
software programming but is a very challenging and highly specialized field. It
requires a judicious mix of master/graduate-level knowledge in software
programming and statistics/mathematics. An entry-level ML professional requires

Adapting ML. It is a big challenge to create an ML
model, evaluate its suitability, performance and efficiency and make its
outcomes acceptable to the hospital/laboratory physicians. Rapid advances in
computing technology, handling of unstructured data and increased use of
Robotics, 5G, Multi-Media (MM) devices have enhanced productivity and quality
of ML linked applications. To deliver accurate and quick results, ML algorithms
must be continuously refined based on the outcome which reflects the current
status of patient/disease. ML relies on efficient OOP
framework like Python and “R”, and to some extent on MATLAB. Therefore,
you must learn such new technologies faster and be proficient. If you implement
the ML model successfully, it can pre-process a lot of healthcare data and
predict the outcome for medical experts to speed up their decision-making. For
successful implementation of ML in the healthcare sector, it is most essential
to keep various algorithms, hardware, application software and data interfaces
fully updated/upgraded. From playing a critical role in patient
care, billing, and medical records; ML technology is helping to develop
alternate staffing models for providing better healthcare at reducing administrative
costs.
Summary. Rapidly advancing technologies necessitate us to learn and share
emerging technologies like ML, Multimedia, 5G and Cloud Computing to remain
current and relevant. ML has a great role in optimising statistical
modelling, disease-drug diagnostics and drug discovery. The tremendous speed of
information retrieval and parallel processing of both structured and
unstructured health-data and availability of GPUs, ML can help mining
bio-information and ensure early detection of the virus. Indeed. ML
brings both challenges and opportunities to the healthcare sector. The
availability of Cloud Computing, Big Data analytic, Open-Source
Software ( OSS) like Python, R, TensorFlow and scikit-learn
will provide much-needed impetus for widespread acceptance of using ML in the
healthcare sector.
ML is invaluable for the Research & Development Work in the complex
fields of Bio-Medical Engineering and Diagnostics. ML should not be treated as
a black-box but used intelligently to supplement human efforts in providing
good, timely and affordable healthcare. If things go wrong, you cannot sue the
machine but the team who developed the algorithm. It is well known that
clinical trials are costly and very time consuming and some of the trials may take
two years or more to complete. ML has great potential to accelerate clinical
trials and research work. Applying ML-based predictive analytics can help
researchers to draw inference from a wide variety of data. Most
researchers feel that ML techniques will be able to analyze current data of
individual patients, and data uploaded using multimedia devices from remote
locations. This can warn physicians at the main hospital about likely emergency
in lower-level hospitals/. PHCs
