Collaborative Filtering Based Recommendation System
-
ABOUT PROJECT:
This is the production of joining Alibaba's data mining innovation competition, which is based on the borrowing data of the Beijing University of Posts and Telecommunications as the basis for designing a user recommendation system based on collaborative filtering algorithm. The android version of the app implements functions such as borrowing history query, hot search recommendation, and user personality recommendation, so that students can borrow books in a easy way.
My DUTY:
1. responsible for first data processing, analyze the main attributes of the datasets, and extract important attributes from the original datasets；
2. responsible for design and creating proper recommendation model by using Python language according to the principle of Collaborative filtering algorithm, use datasets to train this model, and modify parameters of the recommendation system model in order to get expected recommendation result;
3. Build static website to show our work: Show Page;
4. Build MySQL access interface for App version, and test the algorithm processing parts of the App version. - Data_Mining Details

"Pivot" IOT Management Project
-
ABOUT PROJECT:
The project combines the basic characteristics of the Internet of Things, and implements the dynamic management of Internet of Things system by designing a efficient website page based on the Bootstrap front-end framework. Design and implement Web Server on the basis of Django framework, and use ODBC Interface to access datas from remote MySQL databases. In order to test the robustness and system efficiency, design and implement python and shell Script Programs to simulate multi remote devices and a variety of abnormal conditions in IOT system, and achieve efficient methods in web server to deal with.
MY DUTY:
1. Design the web server in Django Framework, implement functions of login, usermanagement, equipments management and automatic alert so on.
2. implement user-friendly front-end pages based on Bootstrap Framework, used Ajax to implement Asynchronous Loading of websites.
3. Design the database structure of SQLite in order to maintain IOT system datas, and the user information.
4. design Python scripts to simulate a dynamic IOT system, test the robustness of Website, and handle abnormalities of IOT system, using email to inform certain user for abnormality. - Html Details

Topic: Recommendation System Based on Collaborative Filtering Algorithm
ABOUT PROJECT:
Collaborative filtering algorithm is the earliest and most widely used type of algorithm in the recommendation algorithm. My graduation design analyzed user-based collaborative filtering algorithm and item-based collaborative filtering algorithm, and based on this, completed the design and implementation of the switching hybrid algorithm and stack hybrid algorithm. Besides, I researched and analyzed the degree of improvement of the recommendation system, which use hybrid algorithms, and verified the accuracy of the algorithms. I finally designed a movie recommendation system model based on the hybrid collaborative filtering algorithm. For the large data set processing problems in the correlation measurement process, I used Spark(distributed data processing platform) to complete and improve the efficiency of data processing. At the same time, on the basis of the movie recommendation algorithm module, I designed and implemented a fully featured movie recommendation website based on Django Web framework. Users can complete user login, registration, management, and other functions through the movie website. At the same time, the website can instantly query the user's history rating record and the movie recommendation list generated thereby.
MY DUTY:
1. design the hybrid collaborative filtering algorithms based on Collaborative Filtering Algorithm, using data to test efficiency of recommendation model, and modify variables to enhance the efficiency, design and implement algorithm section APIs.
2. use Spark as data processing platform to calculate big data sets, generate user-based similarity matrixes, item-based similarity matrixes, then store them into MySQL database.
3. Build full featured Web Movie Recommendation System, including functions of user management, recommendation generating and so on. Link web server with MySQL database and algorithm sections. - Projects Repository

Dormitory Management System
-
ABOUT PROJECT:
This project is course design of Database Design.
The system is designed to realize the database storage of the dormitory information and the large amount of data encountered in the existing dormitory management system. This system has following functions:basic registration of student accommodation; registration for students in every semester; inquiry function to facilitate users' inquiry of basic information of students (to realize inquiry according to various conditions) and inquiry of building information; functions of adding, deleting and modifying user accounts; the ability to add, modify, and delete student basic information. In the process of this in-depth study, as far as possible, a convenient and friendly operation interface and data report are realized.
MY DUTY:
1. Design structures of dormitory information, define their relations and UML graphs, and convert them into MySQL tables;
2. According to software engineering principle to design development process, in charge of back-end web server developement.
3. Implement database access Interface in Python language, then connect them into web server. - Html Repository
