Diurnal variations of resting-state fMRI data: A graph-based analysis

no code implementations12 Oct 2021 Farzad V. Farahani, Waldemar Karwowski, Mark D Esposito, Richard F. Betzel, Magdalena Fafrowicz, Bartosz Bohaterewicz, Tadeusz Marek, Pamela K. Douglas

Also, connectivity and hub analyses showed that the somatomotor, ventral attention, and visual networks are the most densely-connected brain areas in both sessions, respectively, with the first being more active in the evening session and the two latter in the morning session.

On the Similarity of Deep Learning Representations Across Didactic and Adversarial Examples

no code implementations17 Feb 2020 Pamela K. Douglas, Farzad Vasheghani Farahani

The increasing use of deep neural networks (DNNs) has motivated a parallel endeavor: the design of adversaries that profit from successful misclassifications.

Cognitive computational neuroscience

1 code implementation31 Jul 2018 Nikolaus Kriegeskorte, Pamela K. Douglas

To learn how cognition is implemented in the brain, we must build computational models that can perform cognitive tasks, and test such models with brain and behavioral experiments.

Decoding the Encoding of Functional Brain Networks: an fMRI Classification Comparison of Non-negative Matrix Factorization (NMF), Independent Component Analysis (ICA), and Sparse Coding Algorithms

no code implementations1 Jul 2016 Jianwen Xie, Pamela K. Douglas, Ying Nian Wu, Arthur L. Brody, Ariana E. Anderson

Spatial sparse coding algorithms ($L1$ Regularized Learning and K-SVD) would impose local specialization and a discouragement of multitasking, where the total observed activity in a single voxel originates from a restricted number of possible brain networks.
