haxe-neataptic-js

Haxe externs for neataptic.js library for evaluating and training custom neural networks

Installation

1. install library from haxelib haxelib install haxe-neataptic-js
2. init node package config and install neataptic from npm npm i neataptic

Neataptic

This package api maximal like native neatapric api. Full neataptic native usage documentation on Neatapric website

Example of usage 1

init, stringify and parsing of percepron

import neatapticJs.architecture.Network;
import neatapticJs.architecture.Perceptron;
import haxe.Json;
...
//init, stringify and parsing of percepron
var perc = new Perceptron( 3, 2, 1 );
var str = Json.stringify( perc.toJSON() );
Assert.ok( str.indexOf( "nodes" ) != -1 );
Assert.ok( str.indexOf( "connections" ) != -1 );
var parsed = Network.fromJSON( Json.parse( str ) ); //new Neural Network like primal Perceptron

Example of usage 2

Test perceptrone perception

import neatapticJs.architecture.Network;
import neatapticJs.architecture.Perceptron;
import haxe.Json;
//Test perceptrone perception
var perc = new Perceptron( 10, 3, 1 );
var generatePerceptTwoData : () -> TrainingData = () -> {
	var val = Math.floor( Math.random() * 10 );
	return {
		input : [for ( i in 0...10 ) ( ( i == val ) ? 1 : 0 )],
		output : ( val == 2 ) ? [1] : [0]
	}
}
var dataSet = [for ( i in 0...10000 ) generatePerceptTwoData()];
perc.train( dataSet, {
	iterations : 1000,
	rate : 0.1,
} );
Assert.like( perc.activate( [1] )[0], 0 );
