For the tech enthusiasts out there, **Machine Learning (ML)** is a fascinating subset of Artificial Intelligence (AI) that enables computers to learn from data, identify patterns, and make decisions with minimal human intervention. It's about creating algorithms that improve automatically through experience. ML can be divided into several types, including supervised learning (where the model is trained on a labeled dataset), unsupervised learning (where the model learns from unlabeled data), and reinforcement learning (where an agent learns to behave in an environment by performing actions and seeing the results).

If you're not a techie, think of **Machine Learning as teaching your computer to learn from its experiences**. Just like humans learn from every action they take, machine learning allows computers to do the same. So, every time you skip a song on Spotify or like a post on Facebook, you're helping their systems learn more about your preferences, which in turn, makes their recommendations for songs or posts even better.

**_Examples_** 👇

**For the Tech Enthusiasts:**
- **Supervised Learning**: Used in email spam detection where the system learns to filter spam from non-spam emails.
- **Unsupervised Learning**: Helps in market basket analysis to identify product purchase patterns.
