Linear Spatial Integration for Single-Trial Detection in Encephalography
Lucas C. Parra,Christopher V. Alvino,Akaysha C. Tang,Barak A. Pearlmutter,Nick Yeung,Allen Osman,Paul Sajda +6 more
TL;DR: This work demonstrates how a purely data-driven method for learning an optimal spatial weighting of encephalographic activity can be validated against the functional neuroanatomy.
Journal ArticleDOI
Nonnegative matrix factorization for rapid recovery of constituent spectra in magnetic resonance chemical shift imaging of the brain
Paul Sajda,Shuyan Du,Truman R. Brown,Radka Stoyanova,Dikoma C. Shungu,Xiangling Mao,Lucas C. Parra +6 more
TL;DR: An algorithm for blindly recovering constituent source spectra from magnetic resonance (MR) chemical shift imaging (CSI) of the human brain is presented, showing that it can be used to recover tissue-specific spectra given a processing hierarchy that proceeds coarse-to-fine.
Journal ArticleDOI
Quantification of the Roles of Trabecular Microarchitecture and Trabecular Type in Determining the Elastic Modulus of Human Trabecular Bone
TL;DR: The results suggest that trabecular plates play an essential role in determining elastic properties of trabECular bone.
Journal ArticleDOI
Response error correction-a demonstration of improved human-machine performance using real-time EEG monitoring
TL;DR: A brain-computer interface system which uses a set of adaptive linear preprocessing and classification algorithms for single-trial detection of error related negativity (ERN) and the detected ERN is used to correct subject errors.
Proceedings Article
Unmixing Hyperspectral Data
TL;DR: This work assumes linear combinations of reflectance spectra with some additive normal sensor noise and derives a probabilistic MAP framework for analyzing hyperspectral data and develops an algorithm that can be understood as constrained independent component analysis (ICA).
