Tensorflow artificial intelligence learning tensor and detailed explanation of high-order operation examples
ItensorCutting 1.tf.maximum/minimum/clip_by_value() This method is clipped according to the value, and the tensor and threshold are passed in. Maximum turns the data less than the threshold into the threshold. Minimum is to change the data greater than the threshold into a threshold. clip_ by_ Value needs to pass in two thresholds, and the data will […]

Tensorflow tensor
Concept of Tensor Tensor in tensorflow is tensor, which is a mathematical object and a generalization of scalar, vector and matrix. We can directly understand that tensors are lists and multidimensional arrays. The dimension of the tensor is expressed in order: 0-order tensor scalar single value example: a = 1Dimension group of tensor vector […]

Application and exploration of Python artificial intelligence in Snake game
So how do we deal with the data reasonably? We know that the state in Q (s, a) represents the state of the snake. This state includes the position of the apple, the position of the snake, the position of the boundary, the distance between the snake and the boundary, and so on. How to […]

Pytorch to delete the specified row and column in the tenor
preface In Python, if you want to delete the specified row and column in the tendon, you thought you could have a function or assign a line to [] directly. It turns out that it’s not so simple. So you use a curve to save the country. I hope you can point out a more […]
