Machine Learning is a field of computer science that gives computers the ability to learn from data. Unlike traditional programming, where explicit instructions are given, ML algorithms identify patterns, make predictions, and improve their accuracy over time as they are exposed to more data. This learning process allows systems to adapt to new situations and make informed decisions without human intervention. It's a powerful tool for solving complex problems in various domains.

The process typically involves several steps: 1) Data Collection: Gathering relevant data for training the model. 2) Data Preparation: Cleaning, transforming, and organizing the data. 3) Model Selection: Choosing an appropriate ML algorithm based on the problem and data. 4) Training: Feeding the prepared data to the algorithm to learn patterns. 5) Evaluation: Assessing the model's performance on unseen data. 6) Tuning: Adjusting the model's parameters to improve accuracy. 7) Deployment: Integrating the trained model into a real-world application. This iterative process ensures the model is accurate and reliable.

Key features include: 1) Automation: Automating tasks that typically require human intelligence. 2) Adaptability: Adapting to new data and changing environments. 3) Prediction: Predicting future outcomes based on historical data. 4) Pattern Recognition: Identifying hidden patterns and relationships in data. 5) Continuous Improvement: Continuously improving performance with more data. 6) Scalability: Handling large datasets efficiently. These features make ML a valuable tool for various applications.
