I am a Data Scientist and Software Engineer at Amazon FireTV. I use
machine learning for entity matching (also known as pairwise matching)
on live production systems. The work I do matches different media items
together (movies, TV episodes, etc.) from different data providers
(HBO, Netflix, Amazon Prime, etc.) and clusters them for use as a data
catalog, used by search. The model works to match and cluster tens of
thousands of media items prioritizing precision.
Currently, using
random forest model to accomplish this and actively researching LLM
related methods such as BeRT and others prioritizing vector comparison
with transformers and attention.
Previously, I conducted graduate level research for a year as a PhD student at the University of Southern
California (USC) advised by Professsor Gaurav Sukhatme
in RESL (Robotics Embedded Systems Laboratory). I worked at the intersection of machine learning, robotics, and computer vision. My research focused on using machine learning techniques such as deep reinforcement learning and imitation learning for robotic applications including perception and manipulation. I was funded by a USC four year fellowship.
I graduated with my Bachelors in Computer Science at the California Institute of Technology (Caltech), where I worked with Professor Yisong Yue on multi-agent Motion Planning using Imitation Learning. Also I have researched in the UC Berkeley AUTOLab under Professor Ken Goldberg using machine learning to intelligently search for desired objects in shelf environments. Additionally, I have researched in the Stanford Vision and Learning Lab (SVL) under Professor Silvio Savarese using deep reinforcement learning for object retrieval in bins.

Research
I'm interested in reinforcement learning, imitation learning,
and computer vision for general purpose robotic agents focused
on manipulation. Much of my research has focused on the
mechanical search problem searching for physical items in bins
and shelves and how to use robots in dynamic, home settings to
better assist individuals.
Additionally, interested in transformers and attention
for entity matching problems on real world, messy datasets.

Venture Beat Article
LAX-RAY (Lateral Access maXimal Reduction of occupancY support Area) is a system to automate mechanical search for occluded objects on shelves. LAX-RAY couples a perception pipeline predicting target object occupancy support distribution with a mechanical search policy to sequentially select occluding objects to push sideways to quickly reveal the target.

In this work we present a Deep Reinforcement Learning procedure that combines i) teacher-aided exploration, ii) a critic with privileged information, and iii) mid-level representations, resulting in sample efficient and effective learning for the problem of uncovering a target object occluded by a heap of unknown objects. Our appraoch, trains faster and converges to more efficient uncovering solutions than baselines and ablations, and our policies lead to an average improvement for target graspability.
