How to remove overfitting in machine learning
WebAbstract. Overfitting is a fundamental issue in supervised machine learning which prevents us from perfectly generalizing the models to well fit observed data on training data, as well as unseen data on testing set. Because of the presence of noise, the limited size of training set, and the complexity of classifiers, overfitting happens. Web17 okt. 2024 · In machine learning and AI, overfitting is one of the key problems an engineer may face. Some of the techniques you can use to detect overfitting are as follows: 1) Use a resampling technique to estimate model accuracy. The most popular resampling technique is k-fold cross-validation.
