562. <i>IN VIVO</i> ASSESSMENTS OF TAU PATHOLOGIES IN PATIENTS WITH LATE-ONSET PSYCHOSIS: A PET STUDY Open
Background Late-onset psychosis (LOP) has distinct clinical features compared to younger-onset psychosis. While previous postmortem and epidemiological studies have suggested a link between the neural substrates of LOP and neurodegenerativ…

Why Do Some Inputs Break Low-Bit LLM Quantization? Open
Low-bit weight-only quantization significantly reduces the memory footprint of large language models (LLMs), but disproportionately affects certain examples. We analyze diverse 3-4 bit methods on LLMs ranging from 7B-70B in size and find t…

Large-Scale Data Selection for Instruction Tuning Open
Selecting high-quality training data from a larger pool is a crucial step when instruction-tuning language models, as carefully curated datasets often produce models that outperform those trained on much larger, noisier datasets. Automated…

Extracting Filaments Based on Morphology Components Analysis from Radio Astronomical Images Open
Filaments are a type of wide-existing astronomical structure. It is a challenge to separate filaments from radio astronomical images, because their radiation is usually weak. What is more, filaments often mix with bright objects, e.g., sta…
