Description:

mlp

mlp #
mlp is a Dart package for constructing and working with multi-layer perceptron (MLP) neural networks. It provides classes to define neurons, layers, edges, and the overall model, enabling easy creation and manipulation of neural networks for machine learning tasks.
Features #


Define neurons (Neuron class) with various attributes such as value, name, and connections.
Create layers (Layer class) with different types (input, hidden, output) and manage their connectivity.
Establish connections between neurons using edges (Edge class) with optional weights.
Build and manage the entire neural network model (Model class).

Getting started #
To start using the mlp package, add it to your pubspec.yaml:
dependencies:
mlp: ^1.0.0

Then, run pub get to install the package.
Usage #
Here is a simple example to demonstrate how to use the mlp package to create a neural network:
void main() async{
ARFFConverter arffConverter = ARFFConverter();
ARFF arff = await arffConverter.parseARFFFile(fileName: 'assets/penguins.arff');
// Or csv file like that one:
// ARFF arff = await arffConverter.parseARFFFile(fileName: 'assets/penguins.csv');
MultilayerPerceptron mlp = MultilayerPerceptron(
inputLayer: Layer.input(
neurons: arff.getInputLayerNeurons(className: 'species')),
outputLayer:
Layer.output(neurons: arff.getOutputLayerNeurons(className: 'species')),
);
// 'Gentoo','Biscoe',42.8,14.2,209,4700,'female'
// 'Adelie','Biscoe',37.8,20.0,190,4250,'male'
var model = await mlp.createModel(ARFFModelCreationParameter(arff: arff, className: 'species'));
var prediction = mlp.getPrediction(arff: arff, model: model, data: [
ARFFData(name: 'island', value: 'Biscoe'),
ARFFData(name: 'flipper_length_mm', value: '209'),
ARFFData(name: 'bill_length_mm', value: '42.8'),
ARFFData(name: 'bill_depth_mm', value: '14.2'),
ARFFData(name: 'sex', value: 'female'),
ARFFData(name: 'body_mass_g', value: '4700'),
]);
var prediction2 = mlp.getPrediction(arff: arff, model:model, data: [
ARFFData(name: 'island', value: 'Biscoe'),
ARFFData(name: 'flipper_length_mm', value: '190'),
ARFFData(name: 'bill_length_mm', value: '37.8'),
ARFFData(name: 'bill_depth_mm', value: '20.0'),
ARFFData(name: 'sex', value: 'male'),
ARFFData(name: 'body_mass_g', value: '4250'),
]);
print(prediction);
print(prediction2);
}
