Sample and Communication Efficient Fully Decentralized MARL Policy Evaluation via a New Approach: Local TD update

Kavli Affiliate: Jia Liu | First 5 Authors: Fnu Hairi, Zifan Zhang, Jia Liu, , | Summary: In actor-critic framework for fully decentralized multi-agent reinforcement learning (MARL), one of the key components is the MARL policy evaluation (PE) problem, where a set of $N$ agents work cooperatively to evaluate the value function of the global […]

Pulsatile electrical stimulation creates predictable, correctable disruptions in neural firing

Kavli Affiliate: Kathleen Cullen | Authors: Cynthia R Steinhardt, Diana E Mitchell, Kathleen E Cullen and Gene Y Fridman | Summary: Electrical stimulation is a key tool in neuroscience, both in brain mapping studies and in many therapeutic applications such as cochlear, vestibular, and retinal neural implants. Due to safety considerations, stimulation is restricted to […]

Local operator quench induced by two-dimensional inhomogeneous and homogeneous CFT Hamiltonians

Kavli Affiliate: Masahiro Nozaki | First 5 Authors: Weibo Mao, Masahiro Nozaki, Kotaro Tamaoka, Mao Tian Tan, | Summary: We explore non-equilibrium processes in two-dimensional conformal field theories (2d CFTs) due to the growth of operators induced by inhomogeneous and homogeneous Hamiltonians by investigating the time dependence of the partition function, energy density, and entanglement […]

Runaway Gravitational Production of Dark Photons

Kavli Affiliate: Edward W. Kolb | First 5 Authors: Christian Capanelli, Leah Jenks, Edward W. Kolb, Evan McDonough, | Summary: We demonstrate that gravitational particle production (GPP) of a massive, Abelian, vector (Proca) field during inflation in the presence of nonminimal coupling to gravity may suffer from an instability which leads to runaway production of […]

K-theoretic Heisenberg algebras and permutation-equivariant Gromov–Witten theory

Kavli Affiliate: Todor Milanov | First 5 Authors: Todor Milanov, , , , | Summary: We found an interesting application of the K-theoretic Heisenberg algebras of Weiqiang Wang to the foundations of permutation equivariant K-theoretic Gromov–Witten theory. We also found an explicit formula for the genus 0 correlators in the permutation equivariant Gromov–Witten theory of […]

Connection between galaxy morphology and dark-matter halo structure I: a running threshold for thin discs and size predictors from the dark sector

Kavli Affiliate: Luis C. Ho | First 5 Authors: Jinning Liang, Fangzhou Jiang, Houjun Mo, Andrew Benson, Avishai Dekel | Summary: We present a series of studies on the connection between galaxy morphology and the structure of host dark-matter (DM) haloes using cosmological simulations. In this work, we introduce a new kinematic decomposition scheme that […]

Empowering Segmentation Ability to Multi-modal Large Language Models

Kavli Affiliate: Jing Wang | First 5 Authors: Yuqi Yang, Peng-Tao Jiang, Jing Wang, Hao Zhang, Kai Zhao | Summary: Multi-modal large language models (MLLMs) can understand image-language prompts and demonstrate impressive reasoning ability. In this paper, we extend MLLMs’ output by empowering MLLMs with the segmentation ability. The extended MLLMs can both output language […]
