How Machine Learning Works in Healthcare​

Machine learning algorithms analyze vast amounts of medical data, such as images, patient histories, and lab results, to detect patterns and provide actionable insights. Here's how it typically works:

1. Data Collection: Algorithms are trained on extensive datasets like X-rays, genomics, or patient records.
2. Pattern Recognition: The system identifies trends, anomalies, or correlations that might not be obvious to human experts.
3. Predictions & Recommendations: Based on its training, the system offers predictions (e.g., likelihood of disease) or treatment suggestions.
4. Continuous Learning: With new data, the system refines its accuracy over time.
