For a description of the data set and for download go here.

The CUV Library is a C++ framework for easy use of Nvidia CUDA functions on matrices. It contains basic matrix operations and convolutions which can be performed both on the CPU or the GPU. The library also contains python binding so that all functionality can be used in python for fast prototyping.
The CUV Library can be downloaded at http://github.com/deeplearningais/CUV
We also provide a tutorial on an a
simple MLP that learns MNIST to get you started with CUV.
API Documentation is included, but can also be viewed online.
