How To Improve Machine Learning Model Accuracy

DagsHub

This can be done by training machine learning algorithms such as logistic regression, decision trees, random forests, and support vector machines on a dataset containing categorical outputs. So, if you have a large number of features but fewer samples, consider using an algorithm like a decision tree or a linear model.

Statistical Modeling: Types and Components

Pickl AI

Techniques like linear regression, time series analysis, and decision trees are examples of predictive models. At each node in the tree, the data is split based on the value of an input variable, and the process is repeated recursively until a decision is made.
