- Semi-supervised Learning: Semi-supervised learning combines elements of both supervised and unsupervised learning. It leverages a small amount of labeled data along with a large amount of unlabeled data to improve learning accuracy.
- Reinforcement Learning: Reinforcement learning involves training agents to make sequential decisions by interacting with an environment. The agent learns by receiving feedback in the form of rewards or penalties for its actions, with the goal of maximizing cumulative rewards over time.
Machine learning algorithms can be further categorized based on their functionality, such as:
- Regression: Predicting continuous outcomes.
- Classification: Predicting discrete outcomes or assigning labels to data points.
- Clustering: Grouping similar data points together based on their features.
- Dimensionality Reduction: Reducing the number of features in a dataset while preserving important information.
Popular machine learning algorithms include linear regression, decision trees, support vector machines, k-nearest neighbors, neural networks, and deep learning models like convolutional neural networks (CNNs) and recurrent neural networks (RNNs).
