1. Compression of neural network For some large-scale neural networks, their network structure is very complex (it is said that some neural networks of Huawei are composed of hundreds of millions of neurons). It is difficult for us to put this neural network on a small device (such as our apple watch). This requires us to be able to compress t ...

Loops and lists 1, Loop nesting The execution principle of loop nesting: the outer loop is once and the inner loop is complete for x in range(5): for y in range(2, 8): print(x, y) 2, Recognition list 1. List What does a list look like: a list is a container data type (sequence); Take [] as the flag of the container, in which multiple ...

1, Several traversal algorithms of tree 1. Preorder traversal First access the root of T, and then recursively access the root of the subtree. If the tree is ordered, traverse the subtree according to the child's order. The pseudo code for traversing the root of the subtree at position p is: Algorthm preorder(T, p): perform the visit act ...

sort Direct sort () numpy.sort(a[, axis=-1, kind='quicksort', order=None]) Axis: sort along the (axis) direction of the array. 0 means by vertical axis, 1 means by horizontal axis, and None means expand to sort. The default is - 1, which means sort along the last axis. kind: sorting algorithm, which provides fast sorting 'quicksort', mixe ...
