Open Source Deep Learning Server & API
DeepDetect (https://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. It has support for both training and inference, with automatic conversion to embedded platforms with TensorRT (NVidia GPU) and NCNN (ARM CPU).
It implements support for supervised and unsupervised deep learning of images, text, time series and other data, with focus on simplicity and ease of use, test and connection into existing applications. It supports classification, object detection, segmentation, regression, autoencoders, ...
And it relies on external machine learning libraries through a very generic and flexible API. At the moment it has support for:
- the deep learning libraries Caffe, Tensorflow, Caffe2, Torch, NCNN Tensorrt and Dlib
- distributed gradient boosting library XGBoost
- clustering with T-SNE
- similarity search with Annoy and FAISS
Please join the community on Gitter, where we help users get through with installation, API, neural nets and connection to external applications.
