% We first convert theta to the (W1, W2, b1, b2) matrix/vector format, so that this % follows the notation convention of the lecture notes. %将长向量转换成每一层的权值矩阵和偏置向量值 W1 = reshape(theta(1:hiddenSize*visibleSize), hiddenSize, visibleSize); ...
Deep learning:九(Sparse Autoencoder练习) 前言: 现在来进入sparse autoencoder的一个实例练习,参考Ng的网页教程:Exercise:Sparse Autoencoder。这个例子所要实现的内容大概如下:从给定的很多张自然图片中截取出大小为8*8的小patches图片共10000张,现在需要用sparse autoencoder的方法训练出一个隐含层网络所学习到的特征...
而attention得到的affinity matrix对每一个channel上的每一pixel都能学出一个自己的weight,如果同一个channel上的每一pixel的weight都相同,那cross attention则退化为一次bmm。我觉得可能的原因是bmm进行了2次,且中间有relu + norm,而我猜multi-head cross attention可能只在实验中进行了1次。另外multi-head也可能有...
