what are the different types of classification models - manjunath - 12-23-2022
Classification models are a type of machine learning model that are used to predict a categorical output value based on one or more input features. There are many different types of classification models, including:
· Logistic regression: This is a linear model that is used to predict a binary outcome (such as 0 or 1). It is based on the logistic function and is used to model the probability of an event occurring.
· Support vector machines (SVMs): This is a linear model that is used to classify data points by finding the hyperplane that maximally separates the data points into different classes. It is particularly effective in cases where the data is not linearly separable.
· Decision trees: This is a non-linear model that is used to classify data points by recursively partitioning the data based on a set of decision rules. It is a simple and interpretable model that can handle both numerical and categorical data.
· Random forests: This is an ensemble model that is used to classify data points by combining the predictions of multiple decision trees. It is a powerful model that is resistant to overfitting and can handle high-dimensional data.
· Boosting: This is an ensemble model that is used to classify data points by combining the predictions of multiple weak learners. It is a powerful model that can handle complex data and can achieve high accuracy.
· Neural networks: This is a complex, non-linear model that is used to classify data points by learning a set of weights and biases through training. It is a powerful model that can handle complex data and can achieve high accuracy, but it can be resource-intensive and may require a large dataset for training.
