Bits and Memories: Measuring Verbatim Extraction Across LLM Quantization
Akshay Sasi
Language models are almost always quantized before they are deployed, and a growing line of work asks whether quantization also lowers their privacy risk. That work measures privac…
HyperShadow: A Benchmark for Detecting 3D Projections of Higher-Dimensional Spatial Objects
Akshay Sasi
Machine-learning datasets labelled "4D" universally denote three spatial dimensions plus time. We introduce HyperShadow, the first public benchmark in which the fourth, fifth, and…
Pupillometry and Brain Dynamics for Cognitive Load in Working Memory
Nusaibah Farrukh, Malavika Pradeep, Akshay Sasi +2
Cognitive load, the mental effort required during working memory, is central to neuroscience, psychology, and human-computer interaction. Accurate assessment is vital for adaptive…
Cross-Modal Computational Model of Brain-Heart Interactions via HRV and EEG Feature
Malavika Pradeep, Akshay Sasi, Nusaibah Farrukh +2
The electroencephalogram (EEG) has been the gold standard for quantifying mental workload; however, due to its complexity and non-portability, it can be constraining. ECG signals,…
Unveiling the Heart-Brain Connection: An Analysis of ECG in Cognitive Performance
Akshay Sasi, Malavika Pradeep, Nusaibah Farrukh +2
Understanding the interaction of neural and cardiac systems during cognitive activity is critical to advancing physiological computing. Although EEG has been the gold standard for…
