In this lesson, we'll learn how to train a Naive Bayes classifier and a Logistic Regression Classifier-basic machine L Earning algorithms-on JSON text data, and classify it into categories.While the this dataset is still considered a small dataset – only a couple hundred points of data--we'll start to get Bette R results.The general rule was that the Logistic Regression would work better than Naive Bayes, a

Author: Yan Final Solution: 1. The database stores the carriage return line code "\ r \ n "; 2. Because \ r \ n cannot be directly stored in JSON, you can replace it with 3. On the page, VaR strremark = "";If (SYS. ie ){Strremark = data. remark. replace (/} Else {Strremark = data. remark. replace (/} // In jquery's text (VAL) method, replace the carriage return linefeed with the corresponding HTML object

JSON has serious efficiency problems when processing big text data. During deserialization, the CPU usage may even reach 80%, The solution is to split a small segment on the client and assemble it on the server, as shown below: Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/-->1 // large text Optimization 2 var orig

There's nothing to say, just on the code.PHP read CSV file converted to JSON and write new file

Since JSON-formatted files are highly convenient to work with and produce a large number of XML-formatted files every day, there is a need to convert XML-formatted files into JSON-formatted files.Directly below the code, there are two versions, according to the requirements of the free choice:#!/usr/bin/python# -*- coding: utf-8 -*-#Function:Xml_To_Json#version 1.0#Author: Herman#需要用到的两个模块import xmltodict;

There was a problem installing json-server today, and the build file did not generate a dev-server.js file.Start is suspected configuration has a problem, or is not installed correctly, then reinstalled two or three times, or so, depressed.By querying the information, the new version of the VUE-CLI canceled Dev-server.js and dev-client.js instead of webpack.dev.conf.js instead, so configure local access in
