It’s a vector (a direction to move) that Points in the direction of greatest increase of a function (intuition on why) Is zero at a local maximum or local minimum (because there is no single direction of increase) The term "gradient" is typically used for functions with several inputs...
A general feature of Tensor Notation is the compression of multiple functions each of multiple arguments into these compact nuggets. 我们先把坐标放在一边。关于array的另一个令人困惑的事情是它们也可以有所有的向量元素(vector elements)。这必须与rank 1 Tensor(如 T^{i} )仔细区分开来,我们将了解 rank ...

Visual representation of scalar and vector fields using Numpy's contour and quiver functions. Comparison of vector field computed using Numpy's gradient function with the same vector field plotted using analytically deduced expressions for the gradient. Wrote a program for plotting vector field arrows ...
For example, we can say that North and East are 0% similar since $(0, 1) \cdot (1, 0) = 0$. Or that North and Northeast are 70% similar ($\cos(45) = .707$, remember thattrig functions are percentages.) The similarity shows the amount of one vector that “shows up” in the...
