Signatures of visuospatial information foraging during learning of complex environments

Posted by klaurent September 22, 2021September 26, 2022Columbia

Kavli Affiliate: Daphna Shohamy | Authors: David L Barack, Akram Bakkour, Daphna Shohamy and C Daniel Salzman | Summary: Abstract In the real world, making sequences of decisions to achieve goals often depends upon the ability to learn aspects of the environment that are not directly perceptible. Learning these so-called latent features requires seeking information […]

Anomalous elasticity of cellular tissue vertex model

Posted by klaurent September 21, 2021UCSB

Kavli Affiliate: Mark J. Bowick | First 5 Authors: Arthur Hernandez, Michael F. Staddon, Mark J. Bowick, M. Cristina Marchetti, Michael Moshe | Summary: Vertex Models, as used to describe cellular tissue, have an energy controlled by deviations of each cell area and perimeter from target values. The constrained nonlinear relation between area and perimeter […]

Formation and evolution of young massive clusters in galaxy mergers: the SMUGGLE view

Posted by klaurent September 21, 2021MIT

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Hui Li, Mark Vogelsberger, Greg L. Bryan, Federico Marinacci, Laura V. Sales | Summary: Galaxy mergers are known to host abundant young massive cluster (YMC) populations, whose formation mechanism is still not well-understood. Here, we present a high-resolution galaxy merger simulation with explicit star formation and stellar […]

AutoGCL: Automated Graph Contrastive Learning via Learnable View Generators

Posted by klaurent September 21, 2021Berkeley

Kavli Affiliate: Xiang Zhang | First 5 Authors: Yihang Yin, Qingzhong Wang, Siyu Huang, Haoyi Xiong, Xiang Zhang | Summary: Contrastive learning has been widely applied to graph representation learning, where the view generators play a vital role in generating effective contrastive samples. Most of the existing contrastive learning methods employ pre-defined view generation methods, […]

Hyper Suprime-Cam Subaru Strategic Program: A Mass-Dependent Slope of the Galaxy Size-Mass Relation at $z<1$

Posted by klaurent September 20, 2021Tokyo

Kavli Affiliate: Naoki Yasuda | First 5 Authors: Lalitwadee Kawinwanichakij, John D. Silverman, Xuheng Ding, Angelo George, Ivana Damjanov | Summary: We present the galaxy size-mass ($R_{e}-M_{ast}$) distributions using a stellar-mass complete sample of $sim1.5$ million galaxies, covering $sim100$ deg$^2$, with $log(M_{ast}/M_{odot})>10.2~(9.2)$ over the redshift range $0.2<z<1.0$ $(z<0.6)$ from the second public data release of […]

An Overview of Penumbral Moonshine

Posted by klaurent September 20, 2021Chicago

Kavli Affiliate: Jeffrey A. Harvey | First 5 Authors: John F. R. Duncan, Jeffrey A. Harvey, Brandon C. Rayhaun, , | Summary: As Mathieu moonshine is a special case of umbral moonshine, Thompson moonshine (in half-integral weight) is a special case of a family of similar relationships between finite groups and vector-valued modular forms of […]
