Plurality Voting
Majority votingIt is a simple voting method, where the minority obeys the majority.
In classification problems, the prediction result of the sample is usually the one with the most votes becoming the final classification category; if more than one category receives the highest votes, one is randomly selected as the final category.
Other voting methods
Relative majority voting is a relatively common voting strategy in classification problems. In addition, there are absolute majority voting and weighted voting.
- Majority Voting: If the prediction results of multiple classifiers for a certain category are greater than half of the total voting results, then the prediction is for that category, otherwise the prediction is rejected. In this case, the votes are more than half;
- Weighted Voting: Similar to the weighted average method, the number of votes for each category is multiplied by the weight, and finally the weighted votes for each category are summed up. The category corresponding to the maximum value is the final category.
