Machine Learning is one of the essential and effective techniques for analyzing massive, complex medical data. The significant role of machine learning in healthcare is to help the clinician identify disease diagnosing strategies and educate the patients on the potential of disease pathways with treatment methods.

Machine learning in the medical domain is finding appropriate data features to predict the correct classification. Machine Learning models can automatically extract relevant features from huge datasets of patient records stored in electronic health records and use these relevant features. It can detect diseases by monitoring the data and predicting potential diseases.

Machine learning algorithms in the medical field assist the health professional or physician in predicting and diagnosing the disease or disorder at an early stage. Machine learning-based healthcare systems use several techniques, including supervised, unsupervised, semi-supervised, and reinforcement learning. ML techniques are adopted in healthcare medical data applications, ranging from single-dimensional cardiac signals to multi-dimensional Computer-Aided Diagnosis (CAD) medical images.

Recent advancements in machine learning in healthcare are breast cancer prediction, optimizing influenza composition, assessment of chronic kidney disease advancement, heart disease prediction and more.

  • Early detection of diseases in diagnosis and prognosis is a critical issue for healthcare with a huge influx of medical data.

  • Most Commonly used Machine Learning Algorithms in the Medical Field

    Artificial Neural Network: Artificial Neural Networks (ANNs) are often called the most "humanized" machine learning algorithms. ANNs sequentially filter incoming information based on configured parameters, typically minimizing human involvement during training. In the medical field, it is often used for medical imaging and text and speech recognition in radiology.
    Support Vector Machine: Unlike linear regression algorithms, support vector machines (SVMs) are commonly used for classification problems. SVMs are commonly used to classify data in incomplete datasets with missing values and can be applied to various medical tasks such as drug development, adherence prediction, and image and text segmentation.
    Logistic Regression: Logistic regression is commonly used to predict which two outcomes are more likely to occur. Its binary nature makes it relatively easy to utensil, making it one of the most faddish machine learning algorithms in the medical field. In addition to predicting outcome probabilities, logistic regression allows us to see how important each variable is to the outcome. Medical professionals use logistic regression for medical diagnosis, treatment of at-risk patients, and adjustment of action plans.
    Random Forest: This algorithm is used to create different training trees during training to perform classification regression and also helps overcome the overfitting problem of decision trees. Random forests are used for disease risk prediction, ECG, and MRI analysis based on patient history.

    Use Cases for Machine Learning in Medicine Healthcare

    1. Medical Diagnosis: In medicine, an inaccurate or incomplete diagnosis of disease can adversely affect patient outcomes in the worst cases can lead to death. To address one of the most obvious challenges in healthcare, many companies use machine learning to make medical diagnoses more accurate.
    2. Virtual Nursing: In todays busy hospital environment, caregivers can be overwhelmed and struggle to provide each patient with adequate, personalized support. Medical facilities rely on virtual nurses to solve this problem. A virtual nurse is a computer-generated avatar that can interact with patients in a human-like manner. They are meant to be sociable, empathetic, and informative.
    3. Medical Image Processing: As technology advances, medical image analysis requires meticulous attention to detail, making it a tedious task prone to human error. With the help of machine learning, it is possible to detect even the smallest changes in medical scans. Additionally, traditional scan analysis (such as CAT scans MRI) is time-consuming.
    4. Changes in Patient Behavior: Many common illnesses are manageable and even preventable. For example, two types of diabetes, obesity and heart disease, may be avoided by adopting a healthier lifestyle. However, lifestyle adjustments require behavioral changes that require ongoing reminders and follow-up rather than a one-time effort. For this, ML algorithms can aggregate data received from a patients connected medical devices and sensors to gain insight into patient behavior and guide them on this transformational journey.
    i. Changing the Smoking Habits with SmokeBeat: SmokeBeat is an innovative application that passively collects data about your smoking behavior. This application uses the accelerometer of your smartwatch to recognize hand-to-mouth gestures. SmokeBeat processes this data to provide real-time cognitive behavioral therapy incentives. User responses to these incentives are continuously measured and recorded to improve effectiveness.
    5. Robotic Surgery: The use of robots in medicine is not a new trend. Robotic assistance in surgery improves accuracy, allowing access to distinctive areas of the human body with minimal intrusion, and reduces the burden on human surgeons by offloading some of the work to robots.
    6. Drug Discovery: Drug discovery is an extravagant and time-consuming process. Thousands of elements have to be tested together, one proves to be an effective drug.
    7. Identification of High-risk Patients: By combining machine learning-based pattern recognition with automation, physicians can significantly reduce the time it takes to identify high-risk patients.
    8. Optimization of Hospital Management: In general, multiple operations in healthcare facilities are hampered by inefficient management practices. The ever-increasing demand for medical services has led to chaos in hospital management systems. Carefully tuned machine learning-based systems can meaningfully process administrative data and take over most hospital administrative functions.
    9. Health Insurance: Health insurance is an integral part of the healthcare industry and key to improving healthcare access. However, the largely manual health insurance process still has much room for improvement. Machine learning-based pattern recognition algorithms can help detect fraud early. The rule-based fraud detection systems most health insurance companies use today can flag too many claims as potentially fraudulent. ML systems, on the other hand, learn and gradually reduce the likelihood of false positives. ML can also help automate various health insurance processes such as loan origination, underwriting, claims processing, and customer care.
    10.Prediction of Disease Outbreaks: Nowadays, healthcare can collect vast amounts of data from satellites. This embraces real-time data via social media and different historical web data. Machine learning algorithms can aggregate this data and help predict the likelihood of disease outbreaks. An example is predicting malaria epidemics by analyzing monthly rainfall, temperature, and other parameters. This is especially true in third-world countries that lack the medical infrastructure and training to combat these diseases. Knowing about such a serious epidemic allows us to take preventive measures to minimize the negative impact and save lives.
