The AGORA High-resolution Galaxy Simulations Comparison Project. VI. Similarities and Differences in the Circumgalactic Medium

Posted by klaurent February 7, 2024Stanford

Kavli Affiliate: Tom Abel | First 5 Authors: Clayton Strawn, Santi Roca-Fàbrega, Joel R. Primack, Ji-hoon Kim, Anna Genina | Summary: We analyze the circumgalactic medium (CGM) for eight commonly-used cosmological codes in the AGORA collaboration. The codes are calibrated to use identical initial conditions, cosmology, heating and cooling, and star formation thresholds, but each […]

On the evolution of the observed Mass-to-Length relationship for star-forming filaments

Posted by dbos February 7, 2024February 20, 2024Stanford

Kavli Affiliate: Susan E. Clark | First 5 Authors: Jiancheng Feng, Rowan J. Smith, Alvaro Hacar, Susan E. Clark, Daniel Seifried | Summary: The interstellar medium is threaded by a hierarchy of filaments from large scales (~ 100 pc) to small scales (~ 0.1pc). The masses and lengths of these nested structures may reveal important […]

Opening the AI black box: program synthesis via mechanistic interpretability

Posted by klaurent February 7, 2024MIT

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 […]

A Resource Model For Neural Scaling Law

Posted by dbos February 7, 2024MIT

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 […]
