Since the task is simple, it has been considered a toy dataset in the deep learning boundary, so KNN has a good effect. GBDT is a very good algorithm, in Kaggle and other bi

Preface : 工欲善其事, its prerequisite. Find deep learning data, found a python package:Theano. Then began to study, of course, the best information is the official website documents, did not find a better Chinese document, then recorded. Theano official website Tutorial.

Php learning notes: uses the gd library to generate images and implement Random verification codes, Note: I have commented on some basic code. Here, you can set the number of digits of the verification code and the required strings. With my comments, you can easily understand them. Basic Ideas: 1. use mt_rand () to randomly generate a number to determine the string to be obtained and splice the string (thin

1. Beautiful Soup Introduction Beautiful Soup is a python library that parses data from HTML and XML files to provide a customary way to traverse the search and modify the parse tree, which greatly reduces the time it takes to run the crawler. Beautiful soup automatically converts the input document to Unicode encoding, and the output document is converted to UTF-8 encoding. You don't have to think about encoding, unless the document does not s

. When the user agrees to share the user's location with the browser, the map automatically adjusts the window center to that location.The Leaflet.js has two interfaces Locationerror is the callback function that is called after the local address failure is obtained, and Locationfound is the callback that gets the successful local address.Make sure that all the code is before creating div tags and referencing leaflet.js. There should be no problem, you now have a leaflet map to use.Parameter des
