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.

Convert Tensorflow model to Caffe model

I would like to be able to convert a Tensorflow model to Caffe model. I searched on google but I was able to find only converters from caffe to tensorflow but not the opposite. Does anyone have an idea on how to do it? Thanks, Evi

What is the proper way to weight decay for Adam Optimizer

Since Adam Optimizer keeps an pair of running averages like mean/variance for the gradients, I wonder how it should properly handle weight decay. I have seen two ways of implementing it. Only update mean/variance from the gradients based on the…

What is `weight_decay` meta parameter in Caffe?

Looking at an example 'solver.prototxt', posted on BVLC/caffe git, there is a training meta parameter weight_decay: 0.04 What does this meta parameter mean? And what value should I assign to it?

Setting GLOG_minloglevel=1 to prevent output in shell from Caffe

I'm using Caffe, which is printing a lot of output to the shell when loading the neural net. I'd like to suppress that output, which supposedly can be done by setting GLOG_minloglevel=1 when running the Python script. I've tried doing that using the…

When to use in-place layers in Caffe?

By setting the bottom and the top blob to be the same we can tell Caffe to do "in-place" computation to preserve memory consumption. Currently I know I can safely use in-place "BatchNorm", "Scale" and "ReLU" layers (please let me know if I'm wrong).…

How to design deep convolutional neural networks?

As I understand it, all CNNs are quite similar. They all have a convolutional layers followed by pooling and relu layers. Some have specialised layers like FlowNet and Segnet. My doubt is how should we decide how many layers to use and how do we set…
