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 have done work along these very same lines. This project seeks to be a tool with which one can create congressional maps while adjusting the weights of various factors that it takes into account, and further evaluate these maps using the Monte Carlo method to simulate thousands of elections to see how ‘fair’ the maps are.

Software Architecture Diagram

As shown in the figure above, this software will create a congressional district map based off of pre-existing datasets (census and voting history) as well as user-defined factor weighting, which then goes under a Monte Carlo method of simulating thousands of elections in order to evaluate the fairness of this new map. The census data is used both for the user-defined factor weighting and for determining the likelihood to vote for either party (Republican or Democrat), which includes race/ethnicity, income, age, gender, geographical location (urban, suburban, or rural), and educational attainment. The voting history is based on a precinct-by-precinct voting history in Congressional races, and has a heavy weight on the election simulation.

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 a number of improvements that could be made to my paper, so I worked on an intermediate draft for additional feedback before I complete the final version.

I completed the second draft of my paper which required changes in the diagram, motivation for the project. The final draft shall have all the required and suggested materials. I am working on the final version of the poster which requires similar changes as the paper. Currently the application is in testing process. The QR code generation, scanning and the user login/logout process is all set. The aim is to improve the return books feature by adding an additional security layer to prevent book thefts. The librarian gets a list of books away from the library on the homepage and the student is charged a fine if its returned late.

I have been working on wrapping up my project and worked on finishing up the final paper and the poster. The obstacle remains the same where the model gives out very erratic outputs for sentences that are not in its vocabulary but works well with sentences that it has seen before. I will keep continuing to keep working on this and try to figure out a way to make it work, but this goal might be outside the scope of the project given the current workload and time.

During the past week, I have submitted the second version of my paper. After submission, I have continued working on the final parts of the paper. These parts include finishing the social engineering results and making the recommended changes to certain images to enhance my paper. With the given feedback, I have also started making changes to my senior poster which is due Sunday.

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 paper and will look to improve these both this week for final submission.

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 than using Python for the image processing part.

The second video was primarily focussed on the student application. As of now, a user can search for books based on categories like sports, academics, fiction, etc. They can issue books by scanning the QR code as well. The homepage of the student app needs some work, it will show which book is currently issued and give a brief history of the user and their activities in the library. In the coming week, I shall work on the 2nd draft of my poster, hope to complete the project and work on testing.

I worked on finishing the frontend and wrapping up my project and figuring out what metrics to use measure and compare my models with. I also worked on the poster for my project. This upcoming week I will work on wrapping up my final paper and add the description of my second model to the final paper.

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 some new, improved ideas.

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 was. This coming week I want to transfer these results into the next paper draft and continue with the user flow of the software.

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, on the accuracy of my model outside of its dataset.

I have finished the front end of the project, and am trying to wrap it up. One obstacle that I am facing is that my project proposed to have human testing, which will not be possible due to the current situation. I will be working on the poster in the next few days.

This past week I mainly worked on the first draft of my poster. It was much easier to complete since I have the majority of my project finished. In the coming week, I plan to continue my testing with my virtual servers, Kali and Metasploitable. Luckily, I have not encountered any obstacles when trying to use these two for testing. I also plan to continue work on the second draft of my paper.

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 the upcoming week to validate my methods.

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. I also have predictions working (big step) and am currently working on the best way for the user to view their results.

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. Backend wise, i’ve done a lot of setup of methods and variables and i’ve done the first tests with ssh and telnet (long story) integration which didn’t turn out like i wanted. Next on my list is to create the actual objects that the user defines and start hooking up the ability for said objects to do stuff.

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 writing the frontend for the project. 

Week of 23 March

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 not hooped up to the rest of the code.

Next I need to link the C++ code to my Python code, and find a way to to generate meaning full varaibles to pass the processing algorithms. I might rewrite and benchmark the cropping-and-retargeting code in c++ as well.

Working on the logout procedure and to be able to pull up books from the database correctly when the QR code is scanned. The profile page of the librarian and student needs some design elements since the users can view the profile page to see the history of books issued. Planning on working on the second video in the coming week.

The feature extraction module is finished (ready to use) now, but I am still stuck on the modeling module… The model I am using is called VGGVOX which is available on Keras. I am stuck on input pre-processing. The bug is on a function on BatchNormalization(). This function normalizes the activations of the previous layer at each batch. But the issue is not on this function, instead, it is on some deep layers of tensorflow innate functions… which i cannot modify. I am kind of lost which step is wrong exactly.

Project Description: Gender Bias Detection Using Facebook Reactions
by on with No Comments

Gender bias on Facebook might be measured by analyzing the difference in reactions on posts by women or men. My project is studying bias on Facebook pages of United States politicians using Facebook Reactions and post comments. Specifically, I am focusing on politicians running for US Senate in 2020. Data is being collected from Facebook pages of the politicians using a crawler and will be into a database. 

The data will be analyzed by performing sentiment analysis on the comments and using an entropy function on the reactions for each post. The comment analysis is both focused on whether a comment contains more negative or positive words, and if it contains more personal or professional related words. My hypothesis is that female politicians may have comments directed at them that are both more negative, and more focused on personal issues. I am using an entropy function on the reactions to each post to measure how divided the reactions are. Related work used an entropy function on reactions to measure the controversy of a post. My hypothesis is that, in general, posts by female politicians will be more controversial than posts by male politicians.

My project aims to develop models where we can predict the risk of having cancer based on both numerical data and image data. After training all the models, they will be analyzed to see which has the best accuracy and possible ideas to improve the accuracy. After that we can decide the best model to use if we want to predict the risk of having cancer.

Since I uploaded the architecture design last week, this will I will go back to posting the normal updates here – I have been slowly working on my second model that I will compare my initial mode to. I have not faced any obstacles yet except the learning curve that comes with learning Keras, but since Keras is well documented it does not take much time for me to figure out something that I am stuck in. In the upcoming week, I will keep working on the second model and plan to have it finished by the end of spring break.

 I fixed the problem where all returned images look the same. I started looking into how to parallelize the code and learning photography techniques to make images better. 

I have also made a more presentable diagram, which I will also use in my paper and poster.

CS488 – Elevator Pitch
by on with No Comments

Information informs our entire lives. Information shapes public opinion which shapes things like public policy, elections, the health and safety of the public, and more. No one is above the harm that can come from misinformation, which is why we need to fight against its spread.

Fake News as an area of research is relatively new and so some of the aspects are not very well researched, and new aspects to research pop up. Some existing problems in this research are that all of the solutions to these aspects are made in isolation, therefore no one solution can be used to find all instances of fake news, and that most solutions do not have an accessible, comprehensive user platform to disseminate their solution to the people.

This solution that I will provide will be a functional model of a user platform that demonstrates how an engaging and accessible one-stop-shop for fake news detection can work. It allows the user to interact in many different ways that require different levels of effort and is able to scale to include many different automatic detection methods.

In the past week, I worked to finish implementing non content-based filtering which recommends products based on the user’s skin type and desired beauty effects. I was able to apply the concept of TF-IDF to judge which ingredients are heavily related to each beauty effect. Now that all my methods are working, I will implement widgets to the python notebook to create some sort of interface so that I don’t need to change the input each time. I will also start revising the paper and validating my method.
