C# implementation of neural networks library. Contains basic types of layers (dense, convolution, pooling, flatten). Supports single CPU, Multi-CPU and GPU tensor operations (using ManagedCUDA). This project is no longer developed, since I ported it to C++ and greatly expanded (Neuro_).

C# implementation of neural networks library. Contains basic types of layers (dense, convolution, pooling, flatten). Supports single CPU, Multi-CPU and GPU tensor operations (using CUDAfy).
Sample sequential network
var net = new NeuralNetwork("deep_dense_test");var model = new Sequential();model.AddLayer(new Dense(inputs, 5, Activation.Linear));model.AddLayer(new Dense(net.LastLayer, 4, Activation.Linear));model.AddLayer(new Dense(net.LastLayer, inputs, Activation.Linear));net.Model = model;net.Optimize(new SGD(0.02f), Loss.MeanSquareError);List<Data> tData = new List<Data>();for (int i = 0; i < 100; ++i){ var input = new Tensor(net.Layer(0).InputShape); input.FillWithRand(); tData.Add(new Data() { Input = input, Output = input.Mul(1.7f) });}net.Fit(tData, 10, 50, null, 2, Track.TrainError);Sample flow network (streams)
var net = new NeuralNetwork("flow_test");var mainInput = new Dense(2, 2, Activation.Linear) { Name = "main_input" };var auxInput = new Input(new Shape(1, 2)) { Name = "aux_input" };var concat = new Concatenate(new []{ mainInput, auxInput }) { Name = "concat" };net.Model = new Flow(new[] { mainInput, auxInput }, new[] { concat });net.Optimize(new SGD(0.05f), Loss.MeanSquareError);var inputs = new[] { new Tensor(new float[] { 0, 1 }, new Shape(1, 2)), new Tensor(new float[] { 1, 2 }, new Shape(1, 2)) };var output = new Tensor(new float[] { 1, 2, 1, 2 }, new Shape(1, 4));var trainingData = new List<Data> { new Data(inputs, new []{output}) };net.Fit(trainingData, 1, 50, null, 0, Track.Nothing, false);Library can generate basic graphs to track error (train data, test data).
For GPU computation CUDA 10.1 and CudNN 7.6.1.34 are required. Both can be downloaded from NVidia website:
