cuda-convnet代码，可以在http://code.google.com/p/cuda-convnet/下载到。上传到这里为了方便不能上google的童鞋。 Additional features This document will only describe the small differences between cuda-convnet as hosted on Google Code and this version. Dropout Dropout is a relatively new regularization technique for neural networks. See the Improving neural networks by preventing co-adaptation of feature detectors and Improving Neural Networks with Dropout papers for details.
