machine learning

🔍 What is Machine Learning? Machine Learning is a part of Artificial Intelligence (AI) where computers learn from data and experience (without being explicitly programmed) to make predictions or decisions . 💡 Simple Example: Imagine you want a computer to recognize if a message is spam or not . Instead of writing rules like "if it contains ‘lottery’ → spam", You give it thousands of past emails marked as spam or not spam . The ML model learns patterns from the data and starts predicting on its own . 🧠 Types of Machine Learning: Supervised Learning : Data has inputs and correct outputs (like “email” + “spam/ham” label). Algorithms learn from labeled data. 🔁 Example: Predicting marks based on study hours. Unsupervised Learning : Only input data is given (no labels). Used to find patterns , like grouping similar items. 🔁 Example: Customer segmentation in marketing. Reinforcement Learning : A model learns by trial and error , receiv...
