Adapting Appearance-Based Gaze Estimation to Narrow-Range, Long-Duration Screen Viewing
Jordan Prescott, Kleanthis Avramidis, Shrikanth Narayanan
Appearance-based gaze estimation offers a low-cost alternative to infrared eye tracking for screen-based behavioral and clinical applications, however existing models are typically…
MyoCodec: A Streaming Neural Codec for Electromyography
Jihwan Lee, Kleanthis Avramidis, Junhyeok Lee +3
Neural codecs encode continuous signals into compact sequences of discrete tokens, providing an interface for efficient transmission, storage, and token-based sequence modeling. Th…
A Multi-dimensional Framework for Evaluating Generalization in EEG Foundation Models
Aditya Kommineni, Emily Zhou, Kleanthis Avramidis +2
Evaluating foundation models under appropriate adaptation settings is essential for understanding the quality and transferability of the learned representations. Recent EEG foundat…
Aperiodic and Low-Frequency Spectral Bias in Reconstruction based EEG Foundation Models
Aditya Kommineni, Emily Zhou, Kleanthis Avramidis +7
EEG foundation models, pre-trained on large-scale unlabelled EEG data, have emerged as a promising direction towards learning generalizable EEG representations. Despite showing pos…
Looking Into the Past: Eye Movements Characterize Elements of Autobiographical Recall in Interviews with Holocaust Survivors
Emily Zhou, Marcus Ma, Kleanthis Avramidis +2
Eye movement and memory retrieval are deeply and bidirectionally intertwined, however existing literature is generally confined to controlled lab settings. We investigate the relat…
Smiling Regulates Emotion During Traumatic Recollection
Marcus Ma, Emily Zhou, Leonard Ludwig +7
We study when, where, and why 978 Holocaust survivors smile in video testimonies. We create an automatic smile detection model from facial features with an F1 of 85% and annotate d…
Encoding Emotion Through Self-Supervised Eye Movement Reconstruction
Marcus Ma, Jordan Prescott, Emily Zhou +4
The relationship between emotional expression and eye movement is well-documented, with literature establishing gaze patterns are reliable indicators of emotion. However, most stud…
