Quieter Than the Room: Representation Drift and Task Robustness in Speech Encoders
Vsevolod Kovalev, Pranay Manocha
Non-speech interference can change a speech representation without causing comparable task loss. We test eight frozen encoders on four tasks, adding non-speech sounds throughout re…
SEAM: Shortcut-Aware Real-Time Detection of Scripted vs. Spontaneous Speech for Interview Guardrails
Vsevolod, Kovalev, Pranay Manocha
Scripted vs spontaneous speech detection is appealing for interview guardrails, but benchmark performance can be inflated by shortcuts tied to corpus identity, channel conditions,…
CourseTimeQA: A Lecture-Video Benchmark and a Latency-Constrained Cross-Modal Fusion Method for Timestamped QA
Vsevolod Kovalev, Parteek Kumar
We study timestamped question answering over educational lecture videos under a single-GPU latency/memory budget. Given a natural-language query, the system retrieves relevant time…
Thermodynamic Prediction Enabled by Automatic Dataset Building and Machine Learning
Juejing Liu, Haydn Anderson, Noah I. Waxman +4
New discoveries in chemistry and materials science, with increasingly expanding volume of requisite knowledge and experimental workload, provide unique opportunities for machine le…
