FIRE-3: Updated Stellar Evolution Models, Yields, & Microphysics and Fitting Functions for Applications in Galaxy Simulations

Posted by klaurent February 28, 2022March 21, 2022MIT

Kavli Affiliate: Lina Necib | First 5 Authors: Philip F. Hopkins, Andrew Wetzel, Coral Wheeler, Robyn Sanderson, Michael Y. Grudic | Summary: Increasingly, uncertainties in predictions from galaxy formation simulations (at sub-Milky Way masses) are dominated by uncertainties in stellar evolution inputs. In this paper, we present the full set of updates from the FIRE-2 […]

Predicting the Thermal Sunyaev-Zel’dovich Field using Modular and Equivariant Set-Based Neural Networks

Posted by klaurent February 28, 2022March 21, 2022Tokyo

Kavli Affiliate: David N. Spergel | First 5 Authors: Leander Thiele, Miles Cranmer, William Coulton, Shirley Ho, David N. Spergel | Summary: Theoretical uncertainty limits our ability to extract cosmological information from baryonic fields such as the thermal Sunyaev-Zel’dovich (tSZ) effect. Being sourced by the electron pressure field, the tSZ effect depends on baryonic physics […]

Biological error correction codes generate fault-tolerant neural networks

Posted by klaurent February 25, 2022MIT

Kavli Affiliate: Max Tegmark | First 5 Authors: Alexander Zlokapa, Andrew K. Tan, John M. Martyn, Max Tegmark, Isaac L. Chuang | Summary: It has been an open question in deep learning if fault-tolerant computation is possible: can arbitrarily reliable computation be achieved using only unreliable neurons? In the mammalian cortex, analog error correction codes […]

On The Design of a Light-weight FPGA Programming Framework for Graph Applications

Posted by klaurent February 25, 2022Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Jing Wang, Jinyang Guo, Chao Li, , | Summary: FPGA accelerators designed for graph processing are gaining popularity. Domain Specific Language (DSL) frameworks for graph processing can reduce the programming complexity and development cost of algorithm design. However, accelerator-specific development requires certain technical expertise and significant effort […]
