DeepDetect : Open Source API & Deep Learning Server

DeepDetect (http://www.deepdetect.com/) is a machine learning API and server written in C++11. It makes state of the art machine learning easy to work with and integrate into existing applications.

DeepDetect relies on external machine learning libraries through a very generic and flexible API. At the moment it has support for the deep learning library Caffe.

Main functionalities

DeepDetect implements support for supervised deep learning of images and other data, with focus on simplicity and ease of use, test and connection into existing applications.

Supported Platforms

The reference platform with support is Ubuntu 14.04 LTS.

Quickstart

Setup an image classifier API service in a few minutes: http://www.deepdetect.com/tutorials/imagenet-classifier/

Tutorials

List of tutorials, training from text, data and images, setup of prediction services, and export to external software (e.g. ElasticSearch): http://www.deepdetect.com/tutorials/tutorials/

Features and Documentation

Current features include:

high-level API for machine learning
JSON communication format
remote Python client library
dedicated server with support for asynchronous training calls
high performances, benefit from multicores and GPU
connector to handle large collections of images with on-the-fly data augmentation (e.g. rotations, mirroring)
connector to handle CSV files with preprocessing capabilities
connector to handle text files, sentences, and character-based models
range of built-in model assessment measures (e.g. F1, multiclass log loss, ...)
no database dependency and sync, all information and model parameters organized and available from the filesystem
flexible template output format to simplify connection to external applications
templates for the most useful neural architectures (e.g. Googlenet, Alexnet, ResNet, convnet, character-based convnet, mlp, logistic regression)

Documentation

Dependencies

C++, gcc >= 4.8 or clang with support for C++11 (there are issues with Clang + Boost)
eigen for all matrix operations;
glog for logging events and debug;
gflags for command line parsing;
OpenCV >= 2.4
cppnetlib
Boost
curl
curlpp
utfcpp
gtest for unit testing (optional);

Caffe Dependencies

CUDA 7 or 6.5 is required for GPU mode.
BLAS via ATLAS, MKL, or OpenBLAS.
protobuf
IO libraries hdf5, leveldb, snappy, lmdb

Caffe version

By default DeepDetect automatically relies on a modified version of Caffe, https://github.com/beniz/caffe/tree/master_dd_integ

Implementation

The code makes use of C++ policy design for modularity, performance and putting the maximum burden on the checks at compile time. The implementation uses many features from C++11.

Visual Demo

HTML and javascript classification image demo in demo/imgdetect

Examples

Models

List of free, even for commercial use, deep neural nets for image classification, and character-based convolutional nets for text classification: http://www.deepdetect.com/applications/list_models/

Authors

DeepDetect is designed and implemented by Emmanuel Benazera [email protected].

Build

Below are instructions for Ubuntu 14.04 LTS. For other Linux and Unix systems, steps may differ, CUDA, Caffe and other libraries may prove difficult to setup.

Beware of dependencies, typically on Debian/Ubuntu Linux, do:

sudo apt-get install build-essential libgoogle-glog-dev libgflags-dev libeigen3-dev libopencv-dev libcppnetlib-dev libboost-dev libcurlpp-dev libcurl4-openssl-dev protobuf-compiler libopenblas-dev libhdf5-dev libprotobuf-dev libleveldb-dev libsnappy-dev liblmdb-dev libutfcpp-dev

For compiling along with Caffe:

mkdir build
cmake ..
make

If you are building for one or more GPUs, you may need to add CUDA to your ld path:

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda/lib64

If you would like to build with cuDNN, your cmake line should be:

cmake .. -DUSE_CUDNN=ON

Run tests

Note: running tests requires the automated download of ~75Mb of datasets, and computations may take around thirty minutes on a CPU-only machines.

To prepare for tests, compile with:

cmake -DBUILD_TESTS=ON ..
make

Start the server

cd build/main
./dede
