 1) Открыть в Chrome файл index.html<br/>
 2) Открыть консоль F12<br/>
 3) Запустить функцию ini(), которая присваивает случайные веса<br/>
 4) Посмотреть значения массива w<br/>
 5) Запустить функцию checkAll(), которая проверяет все примеры из набора для проверки fullCheckSet и покажет, сколько правильных ответов<br/>
 6) Запустить train(100), 100 эпох обучения нейрона на учебном наборе trainingSet <br/>

/*Описание задачи:
Прямая у = 3х + 2 делит плоскость координат на 2 части:
левая сторона (значение 0);
правая сторона (значение 1).
Сама прямая принадлежит правой стороне.

Цель: по заданным координатам (х,у) определить, к какой стороне принадлежит точка.

Для обучения и проверки работы нейрона используются выборки по 1000 элементов.
*/

//Константы:
const n = 3; //число входящих сигналов
/*
Входные данные: х = [ X0, X1, X2 ], где
X0 - нейрон смещения, всегда равен 1
X1 - координата х
Х2 - координата у
*/

//Переменные:
let w = [], //массив весов
t = 0.0001; // коэффициент скорости обучения
