saddle point

基本解释

In three-dimensions it could even be a saddle point.
在三維空間的時候，這個甚至可以是鞍點。
And so, at this saddle point here, if we go north or south, then we go down on either side to the Valley.
在鞍點的地方，如果我們曏北或者曏南，我們都曏下走到了山穀。
See the point in the middle, at the origin, is a saddle point. If you look at the tangent plane to this graph, you will see that it is actually horizontal at the origin.
我們來看中間的那個點，在原點上，那就是一個鞍點，在這點做一個切平麪,你可以看到這個切平麪,是在原點上水平的。

For if the bulls are indeed back in the saddle, they are going to need these indices to follow along as some point soon.

In addition, we also propose a simpler network for solving global quadratic convex saddle point problem.2.
