I'm currently a senior researching under Jun-Yan Zhu in the Generative Intelligence Lab
as well as Nina Balcan on Theoretical Semi-Supervised Learning. I'm also a head TA for 15-151 Concepts of Mathematics.

Here's a brief overview of my work. My Resume again, for reference.

Battlecode is an MIT AI competition run every year throughout the month of January with 100s of teams and thousands of participants entering code. As a general overview, games consist of two teams, each with control of some number of robots. These robots have different abilities(making money, attacking, creating more robotos, etc),
and can only communicate through bitFlags whose messages must be coded up in some finite range.

There are multiple tournaments throughout the month, ending in a tournament for the top 16 teams getting flown out to MIT for cash prizes. We were lucky enough to be
in the top 16 for the past two years. Last year we went to MIT to watch the final competition.

Here are some of the cooler features from this year:

Like in 2021, we used a stack to store states (look at the first bullet 2021 for more info)

We used a distributed k clustering algorithm for troop movements. All troops reported enemy troops in their range to the main tower, which then found at most 3 main enemy clusters. From here our troops went towards their closest cluster

We spent a lot of time on troop to troop micro-interactions. for deciding whether to attack at a micro level, we considered how many troops we had vs how many troops the enemy had as well as health, cooldown, and land passability

Here are some of the cooler features from this year:

Our home base towers used a stack to store different States. With this in place, we could switch from a state like Default to defending, while pushing Default to the stack. Once we were done defending, we could pop the State Stack and go back to Default mode.
This allowed us to do a lot of tasks as intermediates while still having main tasks

We used priority queues that stored locations of enemy bases, giving priority to those that had the least amount of money, to effectively take over enemy bases when possible

We used bit manipulation to communicate between towers, which all had 24 bit flags that robots in sensor radius could see

We used the Spotify API in conjuction with Google's NLP API to create an app that
classified the mood of your songs. In addition to classification, we were able to query certain moods from
a user and output songs that had the most correlation to the mood that the user wanted.

Implementation

Given a user mood, we first transformed it into a mood vector.
From there, we used Spotify's API to find a subset of songs with similar mood vectors. From here, we created a further embedding that used both spotify's
mood vector and our sentiment analysis result and found the song with the highest dot product with the original user mood vector

We also used a similar process to generate a curated playlist given a specific mood, as well as added ability to log in to your current spotify account and save said playlilst.
Finally, we created a function to plot mood over time, so the user could see how the mood of their music changed over some time period.

The main goal of this project was to take data from the regular season of the NFL and predict the playoffs be computing rankings for each team.

Implementation

We employed two main strategies:

In the first, we try to find rankings of teams, such that for every game between teams i and j, the difference between team
i's score and team j's score is equal to their difference in ranking. This method didn't work well at first, but after taking all nonzero terms in our matrix and making them small values
1^(-15) it was very efficient. We surmise that this is because we were able to increase the stability of the matrix through perturbation

In the next method, we created a matrix that is 32 by 32, such that every entry Aij is equal to the total number of points scored by team i against team j,
with some normalization. Next, we tried to find some strength vector S such that,
when multiplying A by S, we get a vector proportional to S. This becomes an equation where we can use eigenvalues and eigenvectors to find a solution. It
worked better than a naive version of strategy 1, but worse than the perturbed values.

Our goal was to create a program that, given a start and end location, gives a user the safest timely walking path to their destination. We used Manhatten as a test area since they had a lot of crime data for us to use.

Implementation

First, we downloaded all street nodes from OSM, a mapping API. Next, we assigned each node a value based on the amount of crime in the area, specifically weighting crime intensity via
a function that took in severity of a crime as well as decayed in value deending on distance from a node. We also only considered crimes within a certain latitude longitude value of a given node.
From here, given a path, we would then run an A* search on the start and ending nodes, with the weight of each node being the crime rating we had assigned.

All nodes used for our A* Search

The idea of this project was to create a platform that origamists could share their work with each other and also share models that they made with each other along with instructions

Implementation

I first added a login feature with hashing passwords using MD5 so users can be authenticated in a secure manner in the backend. From here, users can look at the designs of their freinds,
add their own designs, and create new designs via a python program embedded into the webpage.

Origami

Models

I've been folding origami for over a decade now, and over time
I've been able to become skilled enough to fold some great models.
Nowadays I do most of my folding at CMU's origami club. Here are some of my favorites from my
origami instagram page

Teaching

I've been teaching origami since I was in middle school. Here are some pics of me teaching from when I was younger:

Me in 8th grade teaching origami to kids in South Carolina

Me in 9th grade teaching origami to kids in Kenya

Me in 10th grade teaching origami to kids in Myanmar

Basketball

I've been playing basketball since around second grade, and I currently play club basketball at CMU. One of my big goals for basketball was being able to dunk. Here's a video of me dunking :)
