Seattle, Washington, United States

Worked on developing a python package for semi-supervised learning to be used by multiple teams using different model architectures for speech recognition tasks, allowing model to use incremental learning methods on time-sensitive data.

Seattle, Washington, United States

Was responsible for developing a novel SSL framework for speech recognition tasks, reducing annotation costs without significant hit in performance.Technical paper related to the work was published in AMLC 2020, framework later integrated into existing ML pipeline.

Boston, Massachusetts

Worked as a member of the data infrastructure team, while collaborating heavily with other teams on various projects to minimize annotation costs on unlabeled real-world data.Identified the problem of unreliable annotators in crowdsourcing websites and implemented methods to block them from annotating company data resulting in better quality annotations for unlabeled data. Developed an SSL pipeline including novel active learning techniques tailored for company needs after analyzing their model training data, helping their deep learner models achieve better performance with lower training costs.Developed a technique to identify which regions of large videos may consist of potentially interesting frames that may boost model performance, and should use for producing data first.

Guwahati Area, India

Developed a web crawler to crawl data from social networks using python in a distributed system andwas involved in generating test data sets for performance analysis of a batch-wise implementation ofdbScan algorithm for k-means clustering, in the Awekar group. Developed a software version of a 2D turn based educational game designed by department of design, under the supervision of Dr. Awekar, and Dr. Bokil. Learnt Python and developed Unity/C# skills.

Guwahati, Assam, India

Developed a 2D turn based educational games designed by department of design, inspired by Tangram, under the supervision of Dr. Awekar, and Dr. Bokil. Developed an educational game to help students learn C programming language, under the supervision of Dr. Awekar, and Dr. Bokil. Learnt Unity/C# & C skills.
