What is Machine Learning?

Machine learning (ML) is a subfield of artificial intelligence (AI) that allows computers to learn from data and improve their performance on specific tasks without being explicitly programmed.

Instead of using rule-based programming, machine learning uses patterns found in data to make predictions or decisions.

Why is Machine Learning Important?

Machine learning powers many technologies we use daily, including:

• Recommendation systems on Netflix and YouTube
• Voice assistants like Siri and Alexa
• Email spam detection
• Predictive text and autocorrect
• Fraud detection in banking

How Does Machine Learning Work?

At a high level, machine learning works by:

1️⃣ Collecting data: Gathering relevant data for the problem.
2️⃣ Training a model: Using algorithms to find patterns in the data.
3️⃣ Making predictions: Applying the trained model to new, unseen data.
4️⃣ Improving over time: Continuously learning with more data to improve accuracy.

Types of Machine Learning

Machine learning can be categorized into:

✅ Supervised Learning
✅ Unsupervised Learning
✅ Reinforcement Learning

In supervised learning, the model learns from labeled data, while in unsupervised learning, the model identifies patterns in unlabeled data. Reinforcement learning involves learning by interacting with an environment and receiving feedback.

You can read about these in detail in our Types of Machine Learning tutorial.

Real-World Applications

Machine learning is used in:

• Healthcare: Predicting diseases and patient outcomes.
• Finance: Algorithmic trading and credit scoring.
• Transportation: Self-driving cars and route optimization.
• Retail: Customer segmentation and demand forecasting.
