Linear Regression 구현

function updateGradient() { var m = datas.length; var alpha = 0.00002; var sum = 0; for(var i=0; i<m; i++){ sum += t0 + t1 * datas[i][0] - datas[i][1]; } var tempT0 = t0 - alpha / m * sum; sum = 0; for(var i=0; i<m; i++){ sum += (t0 + t1 * datas[i][0] - datas[i][1]) * datas[i][0]; } var tempT1 = t1 - alpha / m * sum; t0 = tempT0; t1 = tempT1; //console.log(t0," , ", t1); }

직선으로 regression 하는것.
