Applications of Machine Learning

1. Supervised Learning

Supervised learning is a type of ML where the model is trained on a labeled dataset, meaning that each input data point is paired with the correct output. The goal is to learn a mapping function from the input to the output. Popular algorithms in supervised learning include:

Linear Regression: Used for predicting a continuous value, such as predicting house prices based on features like square footage, number of bedrooms, etc.
Logistic Regression: Used for binary classification tasks, such as whether an email is spam or not.
Support Vector Machines (SVM): Used for classification and regression tasks, SVMs are particularly effective in high-dimensional spaces.

2. Unsupervised Learning

Unsupervised learning involves training the model on an unlabeled dataset, where the model tries to learn the underlying structure or distribution in the data. This type of learning is often used for clustering and dimensionality reduction. Common algorithms include:

K-Means Clustering: A popular clustering algorithm used to group similar data points together.
Principal Component Analysis (PCA): A technique used for dimensionality reduction, which is useful for visualizing high-dimensional data.

3. Reinforcement Learning

Reinforcement learning is a type of ML where an agent learns to make decisions by interacting with its environment. The agent receives rewards or penalties based on its actions and uses this feedback to learn the optimal strategy. Reinforcement learning has been used in various applications, such as:

Game Playing: AlphaGo, developed by DeepMind, famously beat the world champion in the game of Go using reinforcement learning.
