Krishna Somandepalli
PhD Candidate, Electrical & Computer Engineering
I build robust machine intelligence models by learning from multiple views and modalities in datasets. A few application areas of my research are understanding multimedia content, computational imaging, affective computing and developing inclusive technologies. I enjoy working on open-ended problems that contribute to products with a tangible societal impact.

Research Assistant at SAIL, Viterbi School of Engineering, USC
Highlights
- Led research and collaboration of the Multimedia Intelligence and Content Analysis (MICA) group at SAIL with 10 PhD students
- Created three large-scale open-source datasets for computer vision and speech understanding of multimedia content
- Co-created a patent-pending application to analyze language and characters in screenplays and piloted the tool for over 25 film/TV scripts of 5 production companies including Disney and NBCUniversal
- Collaborated with Geena Davis Institute on the Project SeeJane to computationally analyze over 600 movies from 2014-2019
- Partnered with J Walter Thompson to analyze portrayal of women in over 9000 ads nominated to Cannes Lions from 2006-2017
- Co-developed an application for tracking female participation for the United Nations ITU conferences analyzing over 120 hours of meetings
–
Research Intern at Google LLC.
Highlights
- Demonstrated the use of federated learning (FL) for classifying 42 emotion labels at scale in a privacy-preserving manner
- Benchmarked emotion experience and perception federated models on a dataset of ~1500 users and ~3200 raters
- Proposed an algorithm to model raters and estimate their reliability in a distributed setting with a relative improvement of 3% average precision over the state-of-the-art
–
Research Intern at Google LLC.
Highlights
- Developed self-supervised methods to learn robust features of facial movements and audio from ~3M unlabeled videos
- Improved emotion classification system performance by a relative gain of 5% average precision using self-supervised features
–
Research Software Intern at Google LLC.
Highlights
- Designed a data collection framework to localize cartoon characters in animated content
- Adopted computer vision models to detect, track & identify characters in video content and evaluated the system for seven animation genres
–
Jr. Research Scientist at NYU Langone Medical Center
Highlights
- Automated systems for quality control and denoising of functional MRI data reducing data attrition by ~12% over a 6 month period
- Contributed to 5+ journal publications in the field of computational neuroimaging
- Studied test-retest reliability of the fMRI connectome and replicability of the measures in a sample of 120 participants
