How to install

$ npm install n42

Getting started

var n42 = require('n42');
    
// input data
// This is made of sylvester matrix
var input = $M([
    [1.0, 1.0, 0.0, 0.0],
    [1.0, 1.0, 0.2, 0.0],
    [1.0, 0.9, 0.1, 0.0],
    [0.0, 0.0, 0.0, 1.0],
    [0.0, 0.0, 0.8, 1.0],
    [0.0, 0.0, 1.0, 1.0]
]);

// label data
// This is made of sylvester matrix
var label = $M([
    [1.0, 0.0],
    [1.0, 0.0],
    [1.0, 0.0],
    [0.0, 1.0],
    [0.0, 1.0],
    [0.0, 1.0]
]);

var sda = new n42.SdA(input, label, 4, [3, 3], 2);

// Training all hidden layers
sda.pretrain(0.3, 0.01, 1000);

// Tuning output layer which is composed of logistics regression
sda.finetune(0.3, 50);

// Test data
var data = $M([
    [1.0, 1.0, 0.0, 0.0],
    [0.0, 0.0, 1.0, 1.0]
]);

console.log(sda.predict(data));
