Exploring foot pressure patterns for skiing experience classification in a simulator-based environment

Abstract This study investigated whether deep learning can distinguish groups of ski experience based on plantar-pressure distributions measured during simulator-based training and whether classifier outputs change during repeated training. Weight-shift images from 27 participant...

Proofs of Nothing: Zero-Witness Forgeries and the Side Conditions That Prevent Them

A lattice proof verifier is sound only if it binds the proof to a fixed statement the prover cannot choose. We report a post-quantum consensus verifier that does not, and accepts a proof of nothing. In a confidential-transaction opcode, an all-zero proof whose only nonzero field...

Expectation and acoustic neural network representations enhance music identification from brain activity

Abstract During music listening, cortical activity encodes both acoustic and expectation-related information. Prior work has shown that ANN representations resemble cortical representations and can serve as supervisory signals for EEG recognition. Here we show that distinguishing...
