Among the many methods of recommender system, the user-based collaborative filtering recommendation algorithm was first born, and the principle was simpler. The algorithm was introduced in 1992 and used in the mail filtering system, two years later 1994 years Grouplens used for news filtering. Until 2000, the algorithm was the most famous algorithm in the field of recommendation systems.This paper briefly introduces the idea and principle of user-based collaborative filtering algorithm, and fina

JQuery and other JavaScript frameworksAs you've learned, jquery uses the $ symbol as a shorthand for jquery.
What if the other JavaScript framework also uses the $ symbol as a shorthand?
Other JavaScript frameworks include: MooTools, Backbone, Sammy, cappuccino, Knockout, JavaScript MVC, Google Web Toolkit, Google Closure, Ember, Batman and Ext JS.
Some of these frameworks also use the $ notation as shorthand (like jQuery), which may cause the scri

: Collaborative filtering based on user and collaborative filtering based on project.
The recommended algorithm includes two steps in the above scenario:
1. Find out how many users/projects in the database are similar to the target users/projects.
2. Evaluate other users/projects to predict the ratings of the related products you give to your users, given the total weight of users/projects that are more similar to a product user/project.
In this algorithm, the "most similar" means something.

In large applications, it is possible to encounter the following situations when a user is working on a large number of inputs.
For example, the user entered the information in a number of information detection failed, the server had to put the user input information back

Some of these frameworks also use the $ notation as shorthand (like jQuery), which may cause the script to stop running if you are using the same shorthand notation in two different frameworks.
