Tinn: Tiny Neural Network

Tinn is a tiny and dependency free neural network implementation for dotnet. It has three configurable layers: an input layer, a hidden layer and an output layer.

How to get started?

Create a neural network:

var network = new TinyNeuralNetwork(inputCount: 2, hiddenCount: 4, outputCount: 1);

Load a data set:

// This is XOR operation example.
var input = new float[][]
{
    new []{ 1f, 1f }, // --> 0f
    new []{ 1f, 0f }, // --> 1f
    new []{ 0f, 1f }, // --> 1f
    new []{ 0f, 0f }, // --> 0f
};
var expected = new float[][]
{
    new []{ 0f }, // <-- 1f ^ 1f
    new []{ 1f }, // <-- 1f ^ 0f
    new []{ 1f }, // <-- 0f ^ 1f
    new []{ 0f }, // <-- 0f ^ 0f
};

Train the network until a desired accuracy is achieved:

for (int i = 0; i < input.Length; i++)
{
    network.Train(input[i], expected[i], 1f);
}
// Note: you will probably have to loop this for a few times until network improves.

Try to predict some values:

var prediction = network.Predict(new [] { 1f, 1f });  
// Will return probability close to 0f, since 1 ^ 1 = 0.

For more examples see the examples directory and automated tests.

The original library was written by glouw in C.

# Changelog

All notable changes to this project will be documented in this file.

The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/),
and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).

## [Unreleased]


## [2.1.0] - 2023-10-08

### Added

- `TinyNeuralNetwork` now has a constructor to provide pre-trained weights and biases.
- `TinyNeuralNetwork` weights and biases can now be accessed via read-only properties `Weights` and `Biases`.

## [2.0.0] - 2023-07-28

### Changed

- `TinyNeuralNetwork.Train` no longer calculates or returns error. To get current error values call `TinyNeuralNetwork.GetTotalError` instead.
- Improved `TinyNeuralNetwork.Load` and `TinyNeuralNetwork.Save` performance.

### Fixed

- Swapped parameters in `LossFunctionPartialDerivative`, this was a bug.
- Saving and loading is now independent of the current culture.
- Reserved 10% of training data for verification in the hand written number recognition example.

## [1.0.0] - 2021-01-18

### Added

- Initial `TinyNeuralNetwork` implementation based on [C implementation].
- Example of a hand written number recognition (MNIST database).
