Layer (layer) is the largest and most complicated module in Caffe, it is the Basic computing unit of network. Because Caffe emphasizes modular design, only each layer is allowed to complete a class of specific computations, such as convolution operations, pool
1.Caffe is an open source software framework that provides a basic set of programming frameworks, or a template framework for the implementation of deep convolution neural networks, Deep learning algorithms, in parallel to the GPU, and we can define the structure of various convolution neural networks according to the framework, And you can add your own code in this framework, design a new algorithm, the framework of a problem is that only the use of
Recently contacted Caffe got a caffe multiple tags encounter a variety of egg pain to share with you.

The Second Amendment Caffe source code involves the modification of the file has
Caffe.proto,
Convert_imageset.cpp,
Data_layer.cpp,
Io.cpp,
DATA_LAYER.HPP
In Caffe, the model is defined in the. prototxt file, and the structure information for each layer is defined in the file.
Define input:
Input: "Data"
input_shape {
dim:1
dim:3
dim:900
dim:900
}
That is, the definition input named data,batch_size=1, num_channels=3, input_height=900, input_width=900
Define the network layer, taking the convolution layer as an example:
Layer {
name: "Conv1_1"
type: "Convolution"
bottom: "Data"
Top: "con

The type of data that is often used in Caffe is Lmdb or leveldb, so a problem arises: how can I convert from the original picture file to a db (Leveldb/lmdb) file that can run in

Caffe is a clear and efficient framework for deep learning, and the author is a PhD graduate from UC Berkeley Jiayanqing. The Caffe is a pure C++/cuda architecture that supports command line, Python, and MATLAB interfaces, and can be seamlessly switched between CPU and GPU directly. I spent a lot of time configuring the Caffe Environment on Macbookpro (no NVIDIA
The deep learning framework Caffe is compiled and installed in Ubuntu.
The deep learning framework Caffe features expressive, fast, and modular. The following describes how to compile and install Caffe on Ubuntu.1. Prerequisites:
CUDA is used for computing in GPU mode.
We recommend that you use the latest version above 7.0.

Why do you learn Caffe? Because through the Caffe can comprehensive study deep Learning,cuda,spark (Caffeonspark), cudnn,openblas,mkl,c++,python,linux and other knowledge. Before installing Caffe, it is important to install Cuda,blas and so on, CuDNN and Python are optional. Caffe detailed installation procedures refer

Mac Install Caffe can refer to a previous wiki (install Caffe under Mac), of course, if you encounter other problems, please Google.
For a variety of Linux systems, there are already a lot of tutorials on the web.

Here is a brief introduction to the steps to add layer:
1. Add the corresponding Layerparameter message in the Caffe.proto.
2. Add the statement corresponding to the layer under the./include/caffe/layers/path.
3. Add the Cpu,gpu implementation file corresponding to the layer under the./src/caffe

How to add a new type of layer in CaffeReference: https://github.com/BVLC/caffe/issues/684
ADD a class declaration for your layer to the appropriate one of COMMON_LAYERS.HPP,DATA_LAYERS.HPP, LOSS_LAYERS.HPP, neuro N_LAYERS.HPP, or VISION_LAYERS.HPP. Include an inline implementation of type and the *blobs () methods to specify BLOB number requirements. Omit THE*_GPU declarations If you ' ll is implementing CPU code.
