My academic interests lie at the intersection of computing,
linguistics, and artificial intelligence. Some of my work in these areas
can be seen on the Projects tab, or you can download
my Résumé. In my free time, I
enjoy playing viola and violin, listening to classical music, playing
tennis and ping pong, hiking,
competitive Scrabble, and making ice cream.
If you share any of these interests, feel free to get in touch!

This is Jemmin Chang's personal website. Graciously hosted by the

Our term project in 11-411 Natural Language Processing at CMU was to
build a system to ask and answer intelligent questions based on
Wikipedia articles. Somehow, my team won 3rd place (of 17) in the
question asking component.
The short video below explains what we implemented in our system,
and the (very messy) code is hosted
Tailor is a Python tool for automatic generation of original song
lyrics from a N-gram-based language model trained on a set of songs'
lyrics. I started working on it during summer 2015, so it's still
young, but you can check out its progress
GitHub. I'm happy to partner with one of my oldest friends,
Rohit Kapur, on this
For my high school senior project, I built Letterpress Victory, a
Java application with an interactive GUI that allowed the user to enter
Letterpress games and moves, and calculated the
best moves to make. As part of the project, I tested my AI against
similar apps, and found that it well outperformed them (see the video
for the statistics).
My knowledge of AI was much smaller at that time, and the
implementation was quite simple. After a year of CS at CMU, I decided
algorithms, and - as I soon discovered - many new challenges (mostly
related to JS...). But the results far exceeded my expectations: as I
coded, I realized more and more of the design flaws, inefficiencies,
and downright bugs in my original Java program. By the end, everything
was different, from the dictionary data structure to the game tree
exploration algorithm to the GUI layout. And, though I haven't done any
tests yet, I'm sure Lettercrush performs far better than Letterpress
Victory did. I still haven't gotten around to polishing the GUI, but
you can play with it here,
and see the code on GitHub.
Below is my Letterpress Victory presentation video from high school.
The algorithms discussed here are long gone in Lettercrush, replaced by
much more efficient and powerful solutions.
In my Phonetics & Phonology (80-282) class in Fall 2014, I conducted
an experiment to understand how whispering (breathy voice) affects the
distinguishability between minimal pairs of consonants with respect to
voicing. Here's the report, titled Distinguishability of Out-of-Context Whispered
I started playing Scrabble through the School Scrabble program when I was 12 years old. I
attended the National School Scrabble Championships in 2008 and 2009,
partnering with Danilo Vicioso and Bryan Poellot and finishing
26th and 18th, respectively. After graduating
from 8th grade and becoming too old to play School Scrabble, my
Scrabble activity decreased due to the much harder competition in adult
tournaments and my getting more involved with music and other
activities. Recently, upon starting college at Carnegie Mellon, I've
started playing more Scrabble again and attending a few
In Fall 2014 and Spring 2015, I taught a StuCo
class called "Wordplay: Fundamentals of Scrabble Strategy." The course
number is 98-252.
My love for and involvement in classical music has developed
steadily over the years. I began playing viola in the 3rd
grade with my intermediate school orchestra, and started taking private
lessons with Elizabeth Kaplan in high school. Somewhere along the way I
picked up the violin as well.
I continue to practice and study viola at CMU, and I've played viola
and violin in the All-University Orchestra and String Theory. My
favorite, though, is to perform in small chamber ensembles and quartets
- so if you're interested in playing something together, please let me
My favorite period of music is the transition between the Classical
and Romantic periods, and (some of) my favorite composers are
Beethoven, Mendelssohn, Schubert, Tchaikovsky, and Chopin.
