CUDA-enabled implementation of a neural network algorithm for handwritten digit recognition

Using a convolutional neural network as an example, we discuss specific aspects of implementing a learning algorithm of pattern recognition on the GPU graphics card using NVIDIA CUDA architecture. The training time of the neural network on a video-adapter is decreased by a factor of 5.96 and the recognition time of a test set is decreased by a factor of 8.76 when compared with the implementation of an optimized algorithm on a central processing unit (CPU). We show that the implementation of the neural network algorithms on graphics processors holds promise.
