Week 1 Progress

 This is the official start week of the project, and the task of this week is to have a specific discussion about the direction of the project and assign the work to the team members.


First of all, the division of work of our group has been decided as follows:

Group Manager: Yuantong Li

Designer: Zirui Wang

Developer: Jingshi Yang

Technical Writer: Yuanzhen Liu

Each of them would serve as a backup for another role, so that extra hands would be available if progress issues arose.


This project can be completed in many ways, and we temporarily choose bi-LSTM and GRU to complete it.


We have about 6 weeks to complete an entire project, so our plan (tentative) is as follows:

Week 1: Division of work, plan design and data collecting.

Week 2: Complete bi-LSTM method programming, training and testing.

Week 3: Complete GRU method programming, training and testing.

Week 4: Final fine-tuning and testing of the program, poster making, and bench inspection preparation.




The database we found to test our project is linked as follows:

Week 2 Progress

 T his is the second week of the project.   This week we did a lot of programming and a lot of expansions. First of all, we abandoned the bi-LSTM work and used LSTM to complete the project, because bi-LSTM had twice the amount of training as LSTM, and time cost would be a big problem. Then we finished the basic part of the LSTM program. Simple Demostration of LSTM algorithm Besides finishing the LSTM part, we also add two features into our program: · Data processing part. In this part, the program reads the data from the database and processes it in a format that is easy for the main program to read. · Data Visualization Part. In this part, the program will plot the read data for visual viewing.

Week 4 Progress

  This is the fourth week of the project.   The main body of work has been completed. The purpose of this week is to make the final adjustment and prepare the bench inspection. First we made some final adjustments to the program to make it as accurate as possible. ·For example, we found that the deviation of data in a certain interval of the data set was too large, which would lead to the deviation of the whole prediction result when generating the prediction result. As shown in the figure, the initial data circled in the figure is obviously "error data", which in some cases eventually leads to inadequate fitting of our prediction results. Therefore, during training, we need to remove the data with large errors in the original data set to ensure the correctness of our training. Second, we finished the poster over the weekend. Finally, we prepared for the bench inspection. Our bench inspection speech is divided into three parts: Part 1: Brief Introduction By Li Yuantong. Part ...
