What's New
2016/11/30 v1.0.0a3 is released!2016/9/14 tiny-dnn v1.0.0alpha is released!2016/8/7 tiny-dnn is now moved to organization account, and renamed into tiny-dnn :)2016/7/27 tiny-dnn v0.1.1 released!
Features
Reasonably fast, without GPU: With TBB threading and SSE/AVX vectorization.98.8% accuracy on MNIST in 13 minutes training (@Core i7-3520M). Portable & header-only: Runs anywhere as long as you have a compiler which supports C++14.Just include tiny_dnn.h and write your model in C++. There is nothing to install. Easy to integrate with real applications: No output to stdout/stderr.A constant throughput (simple parallelization model, no garbage collection).Works without throwing an exception.Can import caffe's model. Simply implemented: A good library for learning neural networks.

Dependencies
Nothing. All you need is a C++14 compiler (gcc 4.9+, clang 3.6+ or VS 2015+).
Build
tiny-dnn is header-only, so there's nothing to build. If you want to execute sample program or unit tests, you need to install cmake and type the following commands:
cmake . -DBUILD_EXAMPLES=ONmake
Then change to examples directory and run executable files.
If you would like to use IDE like Visual Studio or Xcode, you can also use cmake to generate corresponding files:
cmake . -G "Xcode" # for Xcode userscmake . -G "NMake Makefiles" # for Windows Visual Studio users
Then open .sln file in visual studio and build(on windows/msvc), or type make command(on linux/mac/windows-mingw).
Some cmake options are available:
options | description | default | additional requirements to use |
---|---|---|---|
USE_TBB | Use Intel TBB for parallelization | OFF1 | Intel TBB |
USE_OMP | Use OpenMP for parallelization | OFF1 | OpenMP Compiler |
USE_SSE | Use Intel SSE instruction set | ON | Intel CPU which supports SSE |
USE_AVX | Use Intel AVX instruction set | ON | Intel CPU which supports AVX |
USE_AVX2 | Build tiny-dnn with AVX2 library support | OFF | Intel CPU which supports AVX2 |
USE_NNPACK | Use NNPACK for convolution operation | OFF | Acceleration package for neural networks on multi-core CPUs |
USE_OPENCL | Enable/Disable OpenCL support (experimental) | OFF | The open standard for parallel programming of heterogeneous systems |
USE_LIBDNN | Use Greentea LibDNN for convolution operation with GPU via OpenCL (experimental) | OFF | An universal convolution implementation supporting CUDA and OpenCL |
USE_SERIALIZER | Enable model serialization | ON2 | - |
USE_DOUBLE | Use double precision computations instead of single precision | OFF | - |
USE_ASAN | Use Address Sanitizer | OFF | clang or gcc compiler |
USE_IMAGE_API | Enable Image API support | ON | - |
USE_GEMMLOWP | Enable gemmlowp support | OFF | - |
BUILD_TESTS | Build unit tests | OFF3 | - |
BUILD_EXAMPLES | Build example projects | OFF | - |
BUILD_DOCS | Build documentation | OFF | Doxygen |
PROFILE | Build unit tests | OFF | gprof |
1 tiny-dnn use C++14 standard library for parallelization by default.
2 If you don't use serialization, you can switch off to speedup compilation time.
3 tiny-dnn uses Google Test as default framework to run unit tests. No pre-installation required, it's automatically downloaded during CMake configuration.
For example, type the following commands if you want to use Intel TBB and build tests:
cmake -DUSE_TBB=ON -DBUILD_TESTS=ON .
Customize configurations
You can edit include/config.h to customize default behavior.
Examples
Construct convolutional neural networks
#include "tiny_dnn/tiny_dnn.h"using namespace tiny_dnn;using namespace tiny_dnn::activation;using namespace tiny_dnn::layers;void construct_cnn() { using namespace tiny_dnn; network
Construct multi-layer perceptron (mlp)
#include "tiny_dnn/tiny_dnn.h"using namespace tiny_dnn;using namespace tiny_dnn::activation;using namespace tiny_dnn::layers;void construct_mlp() { network
Another way to construct mlp
#include "tiny_dnn/tiny_dnn.h"using namespace tiny_dnn;using namespace tiny_dnn::activation;void construct_mlp() { auto mynet = make_mlp
For more samples, read examples/main.cpp or MNIST example page.
