ARNI WG Multi-resource-cost optimization of neural network models: Paul Schrater
ARNI WG Multi-resource-cost optimization of neural network models: Paul Schrater
Title: Control when confidence is costly Abstract: We develop a version of stochastic control that accounts for computational costs of inference. Past studies identified efficient coding without control, or efficient control that neglects the cost of synthesizing information. Here we combine these concepts into a framework where agents rationally approximate inference for efficient control. Specifically,…

ARNI Frontier Models for Neuroscience and Behavior Working Group (Priorly: Animal Behavior)
ARNI Frontier Models for Neuroscience and Behavior Working Group (Priorly: Animal Behavior)
Description: Advances in neurotechnology and behavioral tracking have enabled the collection of large-scale neural and behavioral datasets, offering new opportunities to study brain function in complex settings. However, researchers face significant challenges in integrating and analyzing data across different brain regions, individuals, and behavioral contexts. Inspired by recent successes in large-scale “foundation” models in natural language…

Title: The geometry of cognitive flexibility Abstract: Humans and animals are remarkably good at multi-tasking: we quickly learn many different tasks and flexibly switch between them. Theoretical work suggests such cognitive flexibility requires representing the current task and then using this task representation to selectively engage in task-relevant computations. In this talk, I will discuss recent research…

Title: Computing with spikes: A geometric approach Abstract: How can recurrent spiking networks perform computations in a biologically realistic regime? I will outline the progress we have made in answering this question. Our approach follows two principles. First, we don't average over spikes, but focus on the contribution of each individual spike. Second, we study the decision…
