Applications of Machine Learning in the Healthcare Sector

1. Detecting  Diseases and Diagnosis

Machine learning plays a significant role in diagnosing diseases. AI can help in diagnosing diseases that humans have difficulty identifying. Identifying and detecting cancer at an early stage is notoriously hard and often very tricky. IBM Watson Genomics shows how cognitive computing is combined with genome-based tumor sequencing to give a quick diagnosis. Similarly, Berg, which is one of the biggest biopharma companies, is also using AI to introduce oncology treatment.

2. Drug Discovery

ML is widely used in the early-stage drug discovery process. This encompasses research and development technologies like next-generation sequencing and precise medicine, which can aid in discovering alternative approaches to treat complex diseases with multiple contributing factors. It can also be used to make personalized medication for patients with certain special requirements and according to their medical history.

3. Treatment Personalization

Medicine is dynamic and complex. Every patient has a unique set of requirements and specifics. So personalized medication is needed for effective diagnosis and treatment of patients. Machine Learning is helping to expand the horizon of the diagnosis process. IBM Watson Oncology uses the medical history of the patient to create multiple treatment options.

4. Effective Recordkeeping

Maintaining up-to-date patient records is challenging due to monotonous data entry. Machine Learning in healthcare, including optical character recognition (OCR) technology for physicians’ handwriting, will speed up the data entry process. ML simplifies the process to save time, effort, and costs. MIT is working on intelligent health records integrating machine learning for diagnosis and treatment recommendation.

5. Predictive Analytics

Early diagnosis of any disease at the initial stage can potentially save lives. Diabetes, one the most common yet dangerous diseases, is known to cause other serious health issues like vision loss, kidney issues, and heart-related problems. Naive Bayes is a classification algorithm in machine learning that is used for early diagnosis of diabetes.

6. Image Analysis

In the healthcare sector, machine learning is applied to image processing to improve the analysis and interpretation of medical images, such as X-rays, CT scans, and MRIs. One of the well-known machine learning in healthcare examples is the InnerEye project. It was initially built on 3D radiological images, where AI tools were built to distinguish healthy cells and tumors. It could also be used in teeth segmentation and quantitative cancer detection.

7. Natural Language Processing (NLP)

NLP is one of the branches of Artificial intelligence that focuses on human-computer interaction. It enables computers to understand human language and generate responses in a meaningful way. It is used in AI chatbots, language translation and to interpret medical records to make it easily understandable.

8. Data Collection

A physician needs to know the medical history of a patient before suggesting any treatment. This is often challenging as people do not know which data is relevant to disclose. Machine learning in healthcare management will allow professionals to determine the most relevant data and information about the patient and get a prediction of the most likely conditions.

9. Fraud Detection

Artificial engineering and machine learning in healthcare for fraud detection in medical settings involve deploying advanced algorithms and data analysis methods to identify and avert fraudulent actions within the healthcare system. It mostly works in areas like medical billing insurance, and financial transactions. This helps to save time and money for the hospital.

10. Disease outbreak prediction

One of the prominent applications of AI and machine learning in healthcare is outbreak or epidemic predictions. AI has access to large amounts of real-time data through social media,  news, and even satellite imagery. This information can be used to carefully analyze the potential outbreak and warn the general public before it’s too late.

Machine Learning Algorithms Used in Healthcare

●     Artificial Neural Networks (ANN)

Artificial Neural Network (ANN) is the closest to a human-like machine learning algorithm used in healthcare. They process data through various nodes with their specific criteria and need very little human intervention. In healthcare, it is largely used in medical image processing, medical bots, biochemical research, and speech recognition.

●     Logistic regression

Logistic regression, an extensively used machine learning algorithm in healthcare, excels at predicting binary outcomes. The algorithm evaluates the probability of specific events, which is a vital feature in classification tasks within the medical field. It aids in diagnosis, treatment decisions for at-risk patients, and behavior plan adjustments.

●     Support vector machines

Support Vector Machines (SVMs) are primarily utilized for classification purposes, unlike linear regression algorithms. They have mostly been used for drug development, medication adherence prediction, and segmenting medical images and text. SVMs have been used by medical researchers since the 1990s, and they play an important role in classifying data from large, imbalanced, or incomplete data.

●     Random forests

The ML algorithm known as Random Forest constructs a decision tree by processing data through multiple trees and then calculating the average or most likely outcome based on the combined outcomes of all trees. In the healthcare field, this algorithm is used in disease prediction and magnetic resonance imaging (MRI) and electrocardiogram (ECG) data.

●     Naive Bayes classifier

It is one of the most prominent algorithms in use. It is based on the eponymous theorem. Its major advantage is that it has an exceptional ability to work with both independent and dependent variables. The algorithm is highly sensitive and is also an alternative to logistic regression.

Benefits of ML in the Healthcare Sector

●     Improved Diagnosis

Machine Learning can be used by physicians to develop better diagnostic tools. The algorithm is used to better examine medical images like X-rays and MRI scans using pattern recognition to determine the diseases. This technology will allow doctors to save time and improve patient outcomes.
