Supervised Learning Algorithms
Supervised learning algorithms are trained using labeled data, making them ideal for predictive modeling. Here are some key algorithms:
- Linear Regression: Used for predicting continuous values, linear regression is fundamental in understanding relationships between variables.
- Logistic Regression: Despite its name, logistic regression is used for classification problems, especially binary classification.
- Decision Trees: These are versatile algorithms used for both classification and regression tasks, known for their interpretability.
- Support Vector Machines (SVM): SVMs are powerful for classification problems, capable of handling high-dimensional data.
Unsupervised Learning Algorithms
Unsupervised learning algorithms work with unlabeled data, uncovering hidden patterns. Key algorithms include:
- K-Means Clustering: A popular algorithm for clustering analysis, K-Means groups data into K number of clusters.
- Principal Component Analysis (PCA): PCA is used for dimensionality reduction, helping in visualizing high-dimensional data.
- Apriori Algorithm: This algorithm is used for association rule learning, useful in market basket analysis.
Reinforcement Learning Algorithms
Reinforcement learning involves training algorithms to make sequences of decisions. Notable algorithms include:
- Q-Learning: A model-free reinforcement learning algorithm that learns the value of actions in particular states.
- Deep Q Network (DQN): Combines Q-Learning with deep neural networks to solve complex problems.
Neural Networks and Deep Learning
Neural networks form the backbone of deep learning. Essential concepts include:
- Convolutional Neural Networks (CNN): Primarily used for image recognition and processing.
- Recurrent Neural Networks (RNN): Ideal for sequential data, such as time series or natural language processing.
