A hybrid origin for the Martian atmosphere

Posted by klaurent Stanford

Kavli Affiliate: Laura Schaefer | Summary:The Martian isotopic record displays a dichotomy in volatile compositions. Interior volatiles from the mantle record a chondritic heritage (e.g., H, N, Kr, Xe) whereas the atmospheric reservoir of Kr and Xe – which do not currently experience escape – record heritage from a solar-like source. Motivated by disparate inferences […]

Mitigating Forgetting in LLM Supervised Fine-Tuning and Preference Learning

Posted by dbos UCAS

Kavli Affiliate: Yi Zhou | First 5 Authors: Heshan Fernando, Han Shen, Parikshit Ram, Yi Zhou, Horst Samulowitz | Summary: Post-training of pre-trained LLMs, which typically consists of the supervised fine-tuning (SFT) stage and the preference learning (RLHF or DPO) stage, is crucial to effective and safe LLM applications. The widely adopted approach in post-training […]
