target In this chapter, we will recognize the handwritten dataset again, but use SVM instead of kNN. Recognize handwritten numbers In kNN, we directly use pixel intensity as feature vector. This time we will use the directional gradient histogram (HOG) as the feature vector. Here, we use the second-order moment to correct the skew of the image ...

Simple mahjong ai algorithm Write a mahjong game, need to automatically play ai algorithm, do it yourself, although not very smart, but surprised by its simplicity, just record it. Implemented in python. First, summarize the rules of mahjong. The seemingly complex rules of mahjong can be expressed by a formula. Hu = AA and (AAA or AAAA or ABC) ...

Thank you for your reference- http://bjbsair.com/2020-03-27/tech-info/7154/ The simplest way to accelerate the training of neural network is to use GPU. The speed of GPU in the normal operation (matrix multiplication and addition) of neural network is twice faster than that of CPU. As models or datasets grow larger, a GPU will soon become inad ...
