Types of Machine Learning Algorithms
In the field of artificial intelligence, machine learning algorithms are categorised into various types, each serving a unique purpose and function. In this section, we will explore the different types of machine learning algorithms and provide insights into their workings and applications.
Classification algorithms
Classification algorithms are used for separating data into different classes or categories based on their characteristics. One of the most common examples of classification algorithms is the K-Nearest Neighbours (KNN) algorithm, which classifies data points by finding the closest related data points in the same category. Another example is the Support Vector Machine (SVM) algorithm, which finds the hyperplane that best separates the data into the different classes.
Regression algorithms
Regression algorithms are used for predicting continuous values based on data points. Linear regression is a commonly used algorithm that predicts a continuous output based on the linear relationship between the input and output variables. Another example is the Polynomial Regression algorithm, which predicts the values of a dependent variable based on the polynomial relationship between the independent and dependent variables.
Clustering algorithms
Clustering algorithms are used for grouping data points that share similar characteristics. A commonly used clustering algorithm is the K-Means algorithm, which groups together data points based on their proximity to the center of the cluster. Another example is the Hierarchical clustering algorithm, which creates a cluster tree, or dendrogram, of the data points based on their similarity.
Reinforcement learning algorithms
Reinforcement learning algorithms are used for training AI models to make decisions based on rewards and punishments. The Q-Learning algorithm is one such example, where the agent, or the AI model, learns to make decisions by maximizing the rewards and minimizing the punishments associated with each decision.
Understanding the different types of machine learning algorithms is crucial in selecting the appropriate algorithm for specific applications.
