AI Healers: Machine Learning in Medicine


Human beings are intelligent species. We can think critically, make decisions and analyze situations properly.

What is the basis of this superpower? Undoubtedly, it is our ability to perceive our environment that makes us so special. The human race is placed on top of the evolutionary ladder, not because of our developed sensory instincts, but because we can recognize, learn and invent.

That being said; Can computers do the same? This is exactly what machine learning yearns to achieve.

Technically speaking, machine learning is a part of Artificial Intelligence that deals with the development of algorithms and applications, and models.

This field of study enables computer systems to make predictions. It is a new-age development in the IT sector which involves creating statistical techniques and mathematical models to improve computer functioning and analyze data.

For a more relatable view, the current super-techy ChatGPT is nothing but a chat program running on the principles of machine learning.

1. How Does it Affect Medicine?

Now, we come to the core of our reading – How does one inculcate such a software-based tech program in the field of medicine?

Given below are some of the common yet mind-blowing ways in which we use ML for our benefit.

It’s worth noting that while machine learning has shown great progress in these areas, it should always be used as a tool to assist health professionals rather than replace their expertise and judgment.

1.1 Disease Diagnosis

The reach and application of machine learning is vast. ML algorithms analyze diverse patient data to its utmost limit. By patient data, we are referring to genetic information, medical history, lifestyle factors, and other things which might affect the treatment response.

As we know, ML is best at pattern recognition and prediction. What better than using it for the benefit of the patients? This will allow doctors to cover all aspects of a patient’s condition.

Eventually, it will minimize adverse effects and improve patient satisfaction to a great length. Machine learning in personalized treatment and precision medicine holds the promise of delivering targeted and more effective healthcare interventions, leading to improved overall patient care.

1.4 Drug Discovery and Development

Machine learning algorithms, at present, can analyze molecular structures, biological data, and chemical properties at the same time. These are the very prerequisites of building a good drug-target interaction predicting program.

If we can achieve the goal, we’ll be able to conduct virtual screening and predict drug efficacy and safety, much better than we are doing today. By using ML instead of the traditional approaches, researchers can eliminate the trial-and-error methods which usually take a lot of time.

As a result, we’ll end up with a much more developed drug production system that is all the faster than the systems we use to date. Machine learning also facilitates the discovery of novel therapeutics and the advancement of precision medicine.

1.5 Electronic Health Records (EHR) Analysis

You might have come across the scene in Hollywood movies wherein the patient enters his hospital ID and his whole treatment and prescription opens up on the computer. The answer to this technology has been given by machine learning.

Machine learning algorithms analyze EHR data to identify patterns and trends and correlations. Leading to improved clinical decision-making and optimizing treatment plans based on historical patient data.

Another big pro of ML is that it can enable the detection of anomalies or outliers in EHR data, aiding in early diagnosis and intervention. 

1.6 Health Monitoring and Wearable Devices

If you thought that was it, you’re highly mistaken. The health monitoring devices such as the smartwatches and fitness trackers that we wear on our wrists every day – even work on the principles of machine learning.

ML algorithms analyze the continuous streams of data from wearable devices to monitor health parameters in real-time. To list some of their functions – detect anomalies, predict health events, and provide personalized feedback.

If fed data about the user’s lifestyle; It can offer recommendations for physical activity, sleep patterns, and stress management. In this time where every step leads us towards a sedentary and unhealthy life; these modern devices will empower youth to take proactive measures for their health ultimately leading to better health conditions.

2. What is the Need?

It is but natural for any reader to ponder why we even need to put in all this effort. Why not just let the two sectors operate in their respective niches? Well, here’s why-

2.1 Cutting Down the Time Consumed

Traditional medical diagnosis can be complex and time-consuming. Whereas, ML algorithms can analyze vast amounts of patient data in no time. This includes medical records, test results and even imaging scans.

ML models can learn patterns and detect even subtle correlations that may not be immediately apparent to human clinicians. All in all, it improves diagnostic accuracy to a great extent.

2.2 Treatment Planning

At present, machine learning algorithms can help predict the progression of diseases and help assess the patient’s outcomes too. For doing this, the system takes into consideration several diverse criteria such as demographic data, medical history, genetic markers, and obviously – the treatment option to be used.

By working on these predictive capabilities; healthcare providers can develop personalized treatment plans and make intelligent decisions regarding what therapy is to be given, what medication, and so on.

2.3 Image and Signal Analysis

For a doctor who is certainly not a machine, it can be challenging to interpret X-rays, MRIs, ECGs, and EEGs. The difficulty arises not because of the lack of experience or knowledge, but because of the complexity and variability of patterns.

Machine learning techniques, due to their computer vision and core signal processing are best suited for the job.

They can enhance the analysis and interpretation of these medical images and signals, leading to improved detection of abnormalities, early diagnosis, and treatment monitoring.

2.4 Modernizing the Drug Development Process

When we refer to the traditional methods of drug discovery, the first picture is that of the big heavy machinery with sophisticated parts running on a week’s worth of electricity.

The foremost conclusion we make is that – They are expensive and often result in a high rate of failure.

That’s when our saviour joins the arena. Machine learning can help accelerate the process manifold times. How so?

Well, it helps analyze huge amounts of chemical and biological data and identifies potential candidates, and predicts the effectiveness of treatments. ML models can also assist in repurposing existing drugs for new indications.

2.5 Prediction and Early Intervention

Apart from the curative applications, ML also has some preventive ones. One of them is its ability to predict risk factors based on the fed in signs and symptoms. These algorithms can analyze large-scale patient data to identify early warning signs, risk factors and predict the disease onset.

This is a huge boon for healthcare providers as they can now intervene and hopefully control the disease at an early stage.

Moreover, early intervention can potentially prevent the progression of diseases or other complications. ML models can also support population health management by identifying at-risk populations and accordingly optimizing resource allocation.

2.6 Decision Support

Healthcare data is often fragmented across various sources including electronic health records, medical imaging systems, wearable devices, and genetic databases.

For example, a cardiologist would need to study a patient’s blood report, ECG report, medical history as well as his/her family pedigree to give his final verdict about the disease.

Machine learning algorithms can integrate and analyze this diverse data to provide comprehensive patient profiles, decision support tools, and personalized recommendations for doctors. 

3. Blockage in Our Course

As it is well known to all, every modernizing technology is tainted with at least some amount of complications. Addressing these limitations requires collaborations between clinicians, data scientists, ethicists, and regulatory bodies.

Moreover, rigorous evaluation, validation, and transparency in the development as well the deployment of machine learning models in medicine are essential. Not only for their safe application but also for their effective integration into clinical practice.



3.1 Data Availability and Quality 

Machine learning models require large datasets for their training. The datasets should also be diverse and high-quality. However, healthcare datasets are limited. For instance, rare diseases such as Stoneman Syndrome have very few patients across the world. Moreover, many medical profiles have missing data, biased data, or sometimes even incomplete records. It is very much possible that algorithms built on such parameters will prove to be faulty in real-time.

–  Encouraging collaboration among healthcare institutions, researchers, and data scientists. This can facilitate data sharing and the pooling of resources. Thus, creating larger, more diverse datasets for training ML models.– Developing standardized formats and protocols for data collection. Proper storage and integration across healthcare systems can improve data quality and interoperability. 

3.2 Generalizability

Machine learning models trained on specific datasets may not generalize well to different populations. The main reason is the differences in demographics, clinical practices, and data collection protocols. All this can lead to performance variations. Ensuring the generalizability of ML models across diverse patient populations and healthcare systems is an ongoing challenge.

– Pre-training ML models on large datasets from different sources and domains. Followed by fine-tuning target datasets. This is the only probable solution we have at present for the generalization of the program. 

3.3 Interpretability and Explainability

Many machine models we have in the market like the deep neural networks are often considered black boxes. They are complex and quite challenging for the normal mind to interpret. Thus, taking a toll on its interpretability. In healthcare especially, it is crucial to gain the trust and acceptance of healthcare professionals. Therefore, developing interpretable ML models and providing transparent explanations for predictions is still an active area of research.


– Developing ML models with inherently interpretable architectures. If we install nodes such as decision trees or rule-based models, we can provide explainable results.

– Providing comprehensive documentation on the data used and preprocessing steps. Improved decision-making processes can improve transparency and interpretability.

3.4 Ethical and Legal Concerns

The use of machine learning in medicine raises ethical and legal considerations. Ensuring patient privacy, data security, informed consent, and addressing potential biases and discrimination are paramount. The responsible use of machine learning algorithms and adherence to regulations, such as HIPAA, GDPR, and ethical guidelines, are vital considerations.


– Implementing privacy-preserving methods such as secure multi-party computation, federated learning, or differential privacy can protect patient data while allowing collaborative model training.

– Following established regulations and guidelines, such as HIPAA or GDPR, to ensure patient privacy, informed consent, and data security. 

3.5 Limited Clinical Adoption

Integrating machine learning algorithms into clinical workflows and achieving widespread adoption can be challenging. Healthcare professionals may be sceptical of relying solely on machine-generated predictions, preferring a combination of human expertise and ML support. Ensuring seamless integration, usability, and addressing user acceptance issues are crucial for successful implementation.

– Involving healthcare professionals in the design and development process to create user-friendly interfaces and tools that seamlessly integrate into existing clinical workflows.

– Providing transparent explanations and justifications for ML-generated recommendations to foster trust and acceptance among healthcare professionals.



3.6 Regulatory and Safety Considerations

ML is still a baby technology in the field of medicine. Its regulatory terms are still evolving. Regulatory bodies such as the FDA are actively working to establish guidelines and standards for the development and deployment of ML-based medical devices. A yet more critical challenge is ensuring the safety, reliability, and efficacy of ML algorithms in clinical practice.

– Collaborating with regulatory bodies to establish clear guidelines and standards for development. Strict validation and deployment of ML-based medic.


3.7 Bias and Fairness

Machine learning models can inadvertently perpetuate biases present in the training data, leading to discriminatory outcomes. If the training data is biased, the predictions made by the ML models can also be biased, potentially exacerbating healthcare disparities. Addressing and mitigating bias and ensuring fairness in ML algorithms is an important area of research and development.

– Applying appropriate data preprocessing techniques, such as debiasing algorithms, to mitigate bias in training datasets. Regularly monitoring and detecting bias during model development and deployment.
