Questions tagged [caffe]

Caffe is a fast deep learning framework. It supports CPU and GPU processing. Caffe is released under the BSD 2-Clause license. It is based on C++ but provides APIs for Python and Matlab.

Caffe is a fast framework, developed by Berkeley AI Research (BAIR)/ The Berkeley Vision and Learning Center (BVLC). Its architecture is based on pure and and supports and processing without the need to adapt the code for one of the processing units. Caffe provides and interfaces. Caffe is released under the BSD 2-Clause license.

Caffe users share popular models for different tasks with all kinds of architectures and data in the Model Zoo. These models are learned and applied for problems ranging from simple regression, to large-scale visual classification, to Siamese networks for image similarity, to speech and robotics applications.

Caffe: What can I do if only a small batch fits into memory?

I am trying to train a very large model. Therefore, I can only fit a very small batch size into GPU memory. Working with small batch sizes results with very noisy gradient estimations. What can I do to avoid this problem?

How can I implement a weighted cross entropy loss in tensorflow using sparse_softmax_cross_entropy_with_logits

I am starting to use tensorflow (coming from Caffe), and I am using the loss sparse_softmax_cross_entropy_with_logits. The function accepts labels like 0,1,...C-1 instead of onehot encodings. Now, I want to use a weighting depending on the class…

Auto-encoders with tied weights in Caffe

From my understanding, normally an auto-encoder uses tied weights in the encoding and decoding networks right? I took a look at Caffe's auto-encoder example, but I didn't see how the weights are tied. I noticed that the encoding and decoding…

How to convolve two blobs in caffe

In caffe, the convolution layer takes one bottom blob, and convolves it with learned filters (which are initialized using the weight type - "Xavier", "MSRA" etc.). However, my question is whether we can simply convolve two bottom blobs and produce a…
