Nanuk

Neural Netwurk

Shallow neural network lib written in C++, from scratch.

Demo

using namespace nanuk;

Nanuk n({4, 3, 2, 1}); // 4 input neurons, 2 hidden layers, 1 output neuron
n.learing_params(
    10000,  // epochs
    .4      // learning rate [epsilon]
);

// train model
std::ifstream data("data.csv");
n.learn(data, [](unsigned epoch, Scalar cost) {
    std::cout << "Epoch " << epoch << ": " << cost << std::endl;
});

// apply model
Tensor1D output = n({ /* input vector */ });
std::cout << output[0] << std::endl;
