Can We Theoretically Quantify the Impacts of Local Updates on the Generalization Performance of Federated Learning?

Posted by dbos Tokyo

Kavli Affiliate: Jia Liu | First 5 Authors: Peizhong Ju, Haibo Yang, Jia Liu, Yingbin Liang, Ness Shroff | Summary: Federated Learning (FL) has gained significant popularity due to its effectiveness in training machine learning models across diverse sites without requiring direct data sharing. While various algorithms along with their optimization analyses have shown that […]

Map-level baryonification: Efficient modelling of higher-order correlations in the weak lensing and thermal Sunyaev-Zeldovich fields

Posted by Chicago

Kavli Affiliate: Chihway Chang | First 5 Authors: Dhayaa Anbajagane, Shivam Pandey, Chihway Chang, , | Summary: Semi-analytic methods can generate baryon-corrected fields from N-body simulations (“baryonification”) and are rapidly becoming a ubiquitous tool in modeling structure formation on non-linear scales. We extend this formalism to consistently model the weak lensing and thermal Sunyaev-Zeldovich (tSZ) […]

Towards a self-consistent evaluation of gas dwarf scenarios for temperate sub-Neptunes

Posted by dbos Stanford

Kavli Affiliate: Laura Schaefer | First 5 Authors: Frances E. Rigby, Lorenzo Pica-Ciamarra, Måns Holmberg, Nikku Madhusudhan, Savvas Constantinou | Summary: The recent JWST detections of carbon-bearing molecules in a habitable-zone sub-Neptune have opened a new era in the study of low-mass exoplanets. The sub-Neptune regime spans a wide diversity of planetary interiors and atmospheres […]

A spherical harmonic-domain spatial audio signal enhancement method based on minimum variance distortionless response

Posted by dbos Peking

Kavli Affiliate: Huawei Zhang | First 5 Authors: Huawei Zhang, Jihui, Zhang, Huiyuan, Sun | Summary: Spatial audio signal enhancement aims to reduce interfering source contributions while preserving the desired sound field with its spatial cues intact. Existing methods generally rely on impractical assumptions (e.g. no reverberation or accurate estimations of impractical information) or have […]

How DREAMS are made: Emulating Satellite Galaxy and Subhalo Populations with Diffusion Models and Point Clouds

Posted by dbos MIT

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Tri Nguyen, Francisco Villaescusa-Navarro, Siddharth Mishra-Sharma, Carolina Cuesta-Lazaro, Paul Torrey | Summary: The connection between galaxies and their host dark matter (DM) halos is critical to our understanding of cosmology, galaxy formation, and DM physics. To maximize the return of upcoming cosmological surveys, we need an accurate […]
