Machine Learning (ML) is a rapidly evolving field within Artificial Intelligence (AI) that enables systems to learn from data and improve their performance without being explicitly programmed. It’s transforming industries by automating complex processes, making predictions, and driving innovation across various domains.

What is Machine Learning?

Machine Learning is the science of developing algorithms that can recognize patterns in data and make data-driven decisions. At its core, it involves three main types:

• Supervised Learning: The algorithm is trained on a labeled dataset. Common examples include regression and classification.

• Unsupervised Learning: The model explores unlabeled data to find hidden structures, such as clustering and dimensionality reduction.

• Reinforcement Learning: The model learns through trial and error, receiving feedback through rewards and penalties.

Key Applications of Machine Learning

Machine Learning is revolutionizing how we live and work. Some notable applications include:

• Speech recognition (e.g., Siri, Alexa)

• Image classification and computer vision

• Fraud detection in finance

• Predictive analytics in healthcare

• Recommendation systems for e-commerce and streaming platforms

Popular Machine Learning Algorithms

Some widely used ML algorithms are:

• Linear Regression
