🧵 What is Machine Learning?
Machine Learning is a subset of Artificial Intelligence (AI) that enables computers to learn from data and improve their performance over time without being explicitly programmed. It allows machines to make predictions or decisions based on input data.
🌐 Simple Definition:
Machine Learning is the science of making computers learn from data, identify patterns, and make decisions with minimal human intervention.
🔬 Types of Machine Learning
| Type | Description | Examples |
|---|---|---|
| Supervised Learning | Learns from labeled data | Email Spam Detection, Loan Prediction |
| Unsupervised Learning | Finds patterns in unlabeled data | Customer Segmentation, Anomaly Detection |
| Reinforcement Learning | Learns via reward system | Game Bots, Robotics |
💡 How it Works:
- Input Data
- Feature Extraction
- Model Training
- Prediction
- Evaluation
- Optimization
Machine Learning powers Netflix recommendations, helps self-driving cars detect pedestrians, enables fraud detection systems, and assists doctors in diagnoses. It’s not magic—it’s math, data, and computing working together.
