 In the world of Machine Learning, two of the most fundamental approaches to teaching machines how to learn from data are Supervised Learning and Unsupervised Learning. Understanding the difference is key to building the right models and solving the right problems. 🎯 What is Supervised Learning? Supervised Learning is when the model is trained on a labeled dataset, which means each input comes with a known output. 🔹 How it works: You feed the algorithm historical data with input-output pairs. The model learns to map the input to the output. It predicts outputs for new, unseen inputs. 📌 Examples: Spam Detection: Email (input) → Spam/Not Spam (output) Loan Approval: Application data → Approved/Rejected Image Classification: Image → Label (Cat/Dog) 📘 Algorithms Used: Linear Regression Decision Trees Random Forest Support Vector Machines Neural Networks 🔍 What is Unsupervised Learning? Unsupervised Learning deals with unlabeled data. The algorithm tries to find hidden patterns or ...

 Machine Learning (ML) is a subset of artificial intelligence (AI) that enables computers to learn from data and make decisions or predictions without being explicitly programmed.
