MyCaffe is a complete C# re-write of the native C++ CAFFE[1] open source project.

MyCaffe allows Windows C# software developers to use and expand deep learning solutions in their native C# language. All layers except for a few, and nearly every unit test are now provided in C#. Windows programmers can now write their own custom layers in the C# language, yet still enjoy the benefit of an efficient deep learning architecture that supports multi-GPU training on up to 8 headless GPU's using NCCL 1.3.4 ('Nickel').

Now you can create custom layers for MyCaffe in native C# using the full extent of the Windows .NET Framwork!

We have made a large effort to keep the MyCaffe C# code true to the original down to comment with the hope of making it even easier to extend the general CAFFE architecture for all. In addition, MyCaffe uses the same Proto Buffer file format for solver and model descriptions and model binary files allowing an easy exchange between the MyCaffe and C++ CAFFE platforms.

Most of the MyCaffe C# code is very similar to the C++ CAFFE code, for our goal is to extend the CAFFE platform to C# programmers, while maintaining compatibility with CAFFE's solver descriptions, model descriptions and binary weight format.

The C# based MyCaffe open-source project is independently maintained by SignalPop LLC and made available under the Apache 2.0 License.

NOTE: Compute 5.3 now required for CUDA 10.1.243/cuDNN 7.6.2 to support __half sized memory.

IMPORTANT: The open-source MyCaffe project on GitHub is considered 'pre-release' and may have bugs. When you find bugs or other issues, please report them here - or better yet, get involved and propose a fix!

We have several new models supported by MyCaffe with the train_val and solution prototxt ready to go:

• Domain-Adversarial Neural Networks (DANN) as described in [2] with support for source and target datasets.
• ResNet-56 on the Cifar-10 dataset as described in [3].
• Deep convolutional auto-encoder neural networks with pooling as described in [4].
• Policy Gradient Reinforcement Learning networks as described in [5].
• Recurrent Learning of Char-RNN as described in [8] and [9].
• Neural Style Transfer as described in [10] and [11] using the VGG model described in [12]
• Deep Q-Learning [14][15] with Noisy-Net [16] and Prioritized Replay Buffer [17]

For more information on the MyCaffe implementation of Policy Gradient Reinforcement Learning, see MyCaffe: A Complete C# Re-Write of Caffe with Reinforcement Learning by D. Brown, 2018.

MyCaffe now supports the Arcade-Learning-Environment by [6] based on the Stella Atari-2600 emulator from [7], via the AleControl from SignalPop.
For more information, get the AleControl on Nuget, or visit the AleControl on Github.
