《A Sensitivity Analysis of Convolutional Neural Networks for Sentence Classification》里关于Effect of pooling strategy有比较详细的分析实验,结论是:
Our analysis of pooling strategies shows that 1-max pooling consistently performs better than alternative strategies for the task of sentence classification。
《Very Deep Convolutional Networks for Text Classification》里也有k-max pooling和 max-pooling的对比,结论是后者比较好。
