And so did you learn to represent these contour lines as isolines?

那你学会用等线来些等高线了吗？

The two axes on this contour plots are b, on the vertical axis, and w on the horizontal axis.

此等线图上两个轴分别是 b （在垂直轴上） 和 w （在水平轴上）。

And so in the sciences what we do is we draw isolines, lines of equal scalar value.

而在科学中，我绘制等线，即标量相等线。

And you'll also see a contour plot, seeing how the cost gets closer to the global minimum as gradient descent finds better and better values for the parameters w and b. So remember that to do the optional lab.

您还将看到一个等线图，可以看到随着梯度下降为参数 w 和 b 找到越来越，成本如何越来越接近全局最小。因此，请记住，要进行可选实验。

One thing that you will notice is that none of these isolines ever cross.

你会注意到一点是，些等线永远不会相交。

But if I were to connect a lot of these with what are called isolines, where we are seeing they are the same value then you start to see an image here.

但如果我把些用所谓等线连接起来，你会发现它具有相同数， 然后你就会开始看到一个图像。

And then did you learn to use isolines?

然后你学会使用等线了吗？

If you ever move along a isoline, again it is going to be equal levels of potential.

如果你沿着等线移动，那么你将会处于相同电势水平。

And so we could draw in isolines.

我可以画出等线。
