Kavli Affiliate: Max Tegmark | First 5 Authors: David D. Baek, Ziming Liu, Max Tegmark, , | Summary: We present GenEFT: an effective theory framework for shedding light on the statics and dynamics of neural network generalization, and illustrate it with graph learning examples. We first investigate the generalization phase transition as data size increases, […]

Kavli Affiliate: Max Tegmark | First 5 Authors: Eric J. Michaud, Isaac Liao, Vedang Lad, Ziming Liu, Anish Mudide | Summary: We present MIPS, a novel method for program synthesis based on automated mechanistic interpretability of neural networks trained to perform the desired task, auto-distilling the learned algorithm into Python code. We test MIPS on […]
Kavli Affiliate: Max Tegmark | First 5 Authors: Jinyeop Song, Ziming Liu, Max Tegmark, Jeff Gore, | Summary: Neural scaling laws characterize how model performance improves as the model size scales up. Inspired by empirical observations, we introduce a resource model of neural scaling. A task is usually composite hence can be decomposed into many […]
Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Aklant K. Bhowmick, Laura Blecha, Paul Torrey, Luke Zoltan Kelley, Rainer Weinberger | Summary: The first "seeds" of supermassive black holes (BH) can range from $sim10^2-10^6~M_{odot}$. However, the lowest mass seeds ($lesssim10^3 M_{odot}$) are inaccessible to most cosmological simulations due to resolution limitations. We present our new […]

Kavli Affiliate: George R. Ricker | First 5 Authors: Michelle L. Hill, Stephen R. Kane, Paul A. Dalba, Mason MacDougall, Tara Fetherolf | Summary: The Transiting Exoplanet Survey Satellite (TESS) continues to dramatically increase the number of known transiting exoplanets, and is optimal for monitoring bright stars amenable to radial velocity (RV) and atmospheric follow-up […]
Kavli Affiliate: Michael Fausnaugh | First 5 Authors: Yashvi Sharma, Jesper Sollerman, Shrinivas R. Kulkarni, Takashi J. Moriya, Steve Schulze | Summary: Multi-peaked supernovae with precursors, dramatic light-curve rebrightenings, and spectral transformation are rare, but are being discovered in increasing numbers by modern night-sky transient surveys like the Zwicky Transient Facility (ZTF). Here, we present […]

Kavli Affiliate: Herman L. Marshall | First 5 Authors: Fei Xie, Josephine Wong, Fabio La Monaca, Roger W. Romani, Jeremy Heyl | Summary: We report on X-ray polarization measurements of the extra-galactic Crab-like PSR B0540-69 and its Pulsar Wind Nebula (PWN) in the Large Magellanic Cloud (LMC), using a ~850 ks Imaging X-ray Polarimetry Explorer […]
