Fine grained model capability access control mechanism based on machine unlearning

Tongxin xuebao
A fine-grained model capability access control mechanism, named Model-Guard, was proposed to address the lack of capability access control in deployed artificial intelligence models, which may lead to unauthorized misuse of model capabilities.

Feature-based attention selectively modulates connectivity between sensory regions and attention and default networks

, 2018
While numerous previous studies investigated how feature-based attention modulates mean neural activity, little is known about effects of feature-based attention on connectivity between feature-selective regions and nodes of the dorsal attention network ...

Cholinergic modulation supports dynamic switching of resting state networks through selective DMN suppression.

PLoS Computational Biology
Brain activity during the resting state is widely used to examine brain organization, cognition and alterations in disease states. While it is known that neuromodulation and the state of alertness impact resting-state activity, neural mechanisms behind ...

Weakened effective connectivity between salience network and default mode network during resting state in adolescent depression

Frontiers in Psychiatry
Adolescent major depressive disorder (MDD) is associated with altered resting-state connectivity between the default mode network (DMN) and the salience network (SN), which are involved in self-referential processing and detecting and filtering salient ...

Sovereign debt issuance and selective default

Sovereigns issue debt on both domestic and foreign markets and the two debts are uncorrelated in the data. Sovereigns default mostly selectively. We propose a theory to rationalize these observations.
