Senior Capstone, Looking Back

by

Abstract An ever-present problem in the world of politics and governance in the United States is that of unfairly political congressional redistricting, often referred to as gerrymandering. One method for removing gerrymandering that has been proposed is that of using software to create nonpartisan, unbiased congressional district maps, and there have been some researchers who … Read more

I mostly worked on my poster during this week. There were a number of small issues with my original poster created using LaTeX, which I could not fix without delving into a lot of code, so I recreated it using power point and improved it based on Charlie’s feedback. Igor, my advisor, also pointed out … Read more

This week I submitted my second draft of the paper, which required lots of results production as well as time to write. I graphed prediction trends between different materials of foreign data with my model which also was demonstrating how my model was performing. I received great feedback from my advisor regarding the poster and … Read more

Week of April 20th

by

This last week I tried to connect my C++ code with my Python code. I failed because I couldn’t convert from cv::Mat to Numpy Array. There were several problems with that. I will instead save the output of my C++ code as a jpg, and read the jpg in python. This is still considerably faster … Read more

Week of April 13th

by

I finished the first draft of the poster. While doing that, I needed to get the accuracies for my AI model and my image processing algorithm overall. My AI accuracy was around 90% for the testing set. However, I realized my initial idea for measuring image processing accuracy was flawed. I have been working on … Read more

CS488 – Week 13

by

This week we had the first draft of the poster due, which meant producing and visualizing a lot of results from my project. From this motivation, I compared my predictions across very different data (news articles, fictional novels, ect) and also was able to produce a convolution matrix that showed just how accurate my model … Read more

CS 488 Update

by

I’ve mostly been working on making the poster and validating results. I found out that my original plan for validation would not work as nicely, so I will discuss with Xunfei to figure out what I can do. My diagram also needs to be tweaked.

I couldn’t do much due to comps, but collected all information from participants to conduct the validation process. I also ran their results on my software and recorded the results. This week, I will work on extracting relevant reviews from Sephora to evaluate the efficiency of my method.

CS488 – Week 12

by

This week I further improved the pre-processing of sentences so that they are cleaner and easier to read on output. I then downloaded some previous year project posters to help with designing my own and have already completed half of it. It showed me that now I need to work further on results to present, … Read more

CS 488 – Week 11

CS 488 Update

by

In the past week, I mainly worked on implementing a simple interface for my program. I decided to take text inputs for skin type and beauty effects and use a button that returns the recommended products when clicked. To test my program, I collected more input data from participants. I will be using them in … Read more

CS488 – Week 11

by

During the past couple of weeks, I made some good progress on my project. I now have a functioning driver file that the user will run to train or validate a model, or to predict from their input data. This has allowed me to tie up different parts of my software into one functioning project. … Read more

Week of march 23

by

I’ve done some work on the configuration parser to enable to core of the project to work: allowing a user to generate a ui with functionality from a text file. All i’ve been able to do so far runtime wise is to have the user select whether they are using VR mode or AR mode. … Read more

CS 488 – Week 9

by

This past week I worked on my other model that uses both engaging/readable and non-engaging/readable advertisements, I found that this model does not perform well because of the lack of parallel data and sentence structures between the two different sentences. For the next week, I will work on refining my initial model as well as … Read more

Week of 23 March

by

I parallelized some of the python code. I also rewrote the color processing code into C++. The C++ code for individually changing each pixel is 600 times faster. I read up on how to make images of food look better and added more algorithms. I want to improve the algorithms/add more algorithms. They are currently … Read more
