线性回归

为了避免单次变化太大,一步跨过最小点,我们需要使用学习率(leaning rate)乘以导数,这个就是步长,这样就可以防止跨过最小点。 for i in range(num_iterations): [b, w, totalError] = gradient_descent_step(b, w, points, leaning_rate ) return [b, w, totalError] def gradient_descent_step(b: float, w: float, points: np.ndarray, leaning_rate : float): loss_b, loss_w, totalError = loss_function(b, w, points) new_b = b - leaning_rate * loss_b new_w = w - leaning_rate * loss_w return [new_b, new_w, totalError] def draw_figure
