images, these patches are used to generate a basis that can describe their "base", that is, the basis composed of 8*8 = 64 basis on the right, and then a test patch is given, we can use the linear combination of basis according to the formula above, and sparse matrix is A. There are 64 dimensions in a, where there are only 3 non-zero items, so it is called "sparse ". Here, we may wonder why we use the underlying layer as an edge detector? What is the

stage, the granularity of use cases is that each use case can describe a complete interaction between the operator and the computer.Mistakes in use cases and functions Functions and use cases are essentially different. 1. The function exists without the user's desire. For example, the function of describing a bicycle is that it can ride and carry things, and no one will use it. 2. functions are isolated.

The red part of the XPath is "/html/body/div[4]/div/div[1]/div[2]/div[2]/ul/li[11", and, obviously, is the absolute path, specifically why it failed, and I now boil it down to an absolute path. Self-summary, there are currently two solutions:1. If the XPath parsing is not correct, then the simplest solution is to keep the last label subscript, the rest is deleted, starting from the body.2. Rewrite it as a relative path: "//div[@class =\" p-base\ "]/ul/li[11]
