What is the difference between hard and soft voting classifiers?
In classification problems, there are two types of voting: hard voting and soft voting. Hard voting entails picking the prediction with the highest number of votes, whereas soft voting entails combining the probabilities of each prediction in each model and picking the prediction with the highest total probability.
What is voting classifier in Python?
A voting classifier is a machine learning estimator that trains various base models or estimators and predicts on the basis of aggregating the findings of each base estimator. The aggregating criteria can be combined decision of voting for each estimator output.
Why soft classifier achieves higher performance?
This is called soft voting. It often achieves higher performance than hard voting because it gives more weight to highly confident votes. All you need to do is replace voting=”hard” with voting=”soft” and ensure that all classifiers can estimate class probabilities.
