Early Research Projects

In middle school and high school I threw myself into science fairs and research competitions, exploring computer vision, speech recognition, and music analysis. These projects are early steps, full of trial-and-error and youthful ambition. They show where my interest in building intelligent systems began.

2010

Semantic Image Analysis and Image Exploration

Extending my previous research, I built an image search engine that searches images based on their semantic concepts.

2008

Content-Based Image Retrieval

I built an image search that combines color and texture to find similar images.

2010

Continually Adapting Speech Recognition Models

I improved MIT CSAIL's speech recognition engine to enable it to adapt continually to user input.

2007

Acoustic Music Similarity Analysis

I built a fully automatic approach for recommending music based on "how it sounds," using musical characteristics like instrumentation, tempo, and mood.

2006

RFID-Based Robot Navigation

In my 8th grade science fair project, I explored how RFID technology can be used to improve robot navigation algorithms.
