Introduction to DeepDetect

Welcome to DeepDetect documentation DeepDetect is a deep learning API and server written in C++11. It makes state of the art deep learning easy to work with and integrate into existing applications. It has support for backend machine learning libraries Caffe, Tensorflow and XGBoost. DeepDetect boasts the following features: General High level & generic API for machine learning & deep learning JSON communication format Remote Python client library Embedded server with support for asynchronous training calls High performance, benefits from multicore CPU and GPU Flexible input / output connectors for text, images, raw data (CSV, SVM) Flexible template output format to simplify connection to external applications (e.

Quickstart

Quickstart Amazon AMI images and Docker are the easiest way to go. Both contain a ready to go deepdetect server as well as pre-trained googlenet, resnet_50 image classification models and many others for the AMIs. This allows to spin up an image classification service in minutes on a variety of machines with both CPU and GPU support. Amazon AMI images If your target is Amazon AWS, we recommend you take a look at our official GPU AMI or CPU AMI.

DeepDetect Performance Report

Performance This report documents the performances of the DeepDetect Open Source Deep Learning server on a variety of platforms and popular or particularly effective neural network architectures. The full server source code is available from https://github.com/jolibrain/deepdetect. The reported performances use a customized version of Caffe as backend. Code repository : jolibrain/dd_performance Reference platforms Given different platforms, the result should serve as a reference for parties and users interested in choosing the right NN model for their work on their server or embedded systems.

Installing DeepDetect

Installation DeepDetect is written in C++11 with professional support for Linux platforms. The latest release can be found at DeepDetect Releases. For the most up-to-date installation information, see the main README Note: the platforms with support are Ubuntu 14.04 LTS and 16.04 LTS. DeepDetect may also be compiled from source on other platforms such as OSX. If you need to do so and are experiencing difficulties, request help on Github.

Using DeepDetect

Usage This section assumes DeepDetect has been built from sources. Make sure either dede is in your PATH or provide a path to it, or run dede from the build repository: cd deepdetect/build ./main/dede –help Default server is listening on localhost:8080: $ dede DeepDetect [ commit 73d4e638498d51254862572fe577a21ab8de2ef1 ] Running DeepDetect HTTP server on localhost:8080 The help can be obtained with: $ dede –help Flags from /home/beniz/projects/deepdetect/dev/deepdetect/main/dede.cc: -jsonapi (whether to use the JSON command line API (0: HTTP server JSON, 1: commandline JSON, 2: commandline no JSON) type: int32 default: 0 Flags from /home/beniz/projects/deepdetect/dev/deepdetect/src/httpjsonapi.

Training from images

Train Images DeepDetect uses an image connector to train and predict from images. For a comprehensive list of parameters to the image input connector, see the API Connectors section. For a complete tutorial on how to train from images, see here. Training Training from images in practice requires large amounts of data so the connector assumes they are available from the hard drive in the following manner: Every class is a repository of images The class name is the repository name Pass the repository that contain all classes to DeeDetect and the connector will handle them.

Training from CSV

Train CSV DeepDetect uses a dedicated connector to train and predict from CSV data. At prediction time it is possible to use raw CSV line without the header, and without reading them from a file. For a comprehensive list of parameters to the CSV input connector, see the API Connectors section. For a complete tutorial on how to train from CSV data, see here. Training Training reads from CSV files and allows some pre-processing to be applied by DeepDetect without modification to the original data.

FAQ

Frequently Asked Questions How to specify server host and port ? ./dede -host yourhost -port 8888 and replace yourhost and 8888 by your own values. Default values are localhost and 8080 respectively. What are the machine learning frameworks and algorithms supported by the server ? Two libraries are supported at the moment: Caffe, one of the most powerful deep neural network frameworks. Caffe has support for many neural architectures, including logistic regression, multi-layer perceptron, convolutional networks, recurrent nets, etc…
