Individual variability of neural computations underlying flexible decisions
The ability to flexibly switch our response to external stimuli according to contextual
information is critical for successful interactions with a complex world. Context-dependent …

Dynamic reinforcement learning reveals time-dependent shifts in strategy during reward learning
Different brain systems have been hypothesized to subserve multiple “experts” that compete
to generate behavior. In reinforcement learning, two general processes, one model-free …

Partial observation can induce mechanistic mismatches in data-constrained models of neural dynamics
One of the central goals of neuroscience is to gain a mechanistic understanding of how the
dynamics of neural circuits give rise to their observed function. A popular approach towards …

TOWARDS THE ESTIMATION OF CAUSAL NETWORKS BY THE INFORMATION IMBALANCE APPROACH
M Allione - 2024 - webthesis.biblio.polito.it
Inferring the presence of causal links from observational data is a challenging task which
typically goes under the name of causal discovery. After reviewing the basic concepts of this …
