Selecting GPTQ Damping from the Calibration Set by Nested-Ridge Leave-One-Out

GPTQ-style post-training quantization adds λI to the calibration Hessian before inverting it, with λ a fixed fraction of the mean diagonal (one percent in the GPTQ authors' code, five percent in a maintained implementation) that ignores how many calibration rows there are. Small...

Input Calibration and a Specificity Audit of Auditory-Scene-Analysis Cue Scores in Music Foundation Models

Do music foundation models encode auditory-scene-analysis (ASA) cues, the grouping principles behind source perception? A high cue score alone cannot answer this: the ordering may be inherited from the model's input transform or, for timing, arise from onset positions alone. We i...

Adaptation, Not Priming: A Repulsive In-Context Aftereffect Carried by a Sparse Set of Attention Heads

In-context learning is assumed to assimilate: repeated exposure pulls the next prediction toward the repeated pattern, as induction and copy mechanisms attest. We report the opposite sign for graded scalar attributes, and establish three things about it. The phenomenon. Across fi...

The Verdict Is a Function of the Slice: Auditing a Published Quantization Superiority Claim

A published comparison is read as deployment guidance, and what that reader needs is that its verdict holds on the files they are about to download. Two moves are supposed to make such a reading trustworthy: fix what will be read before the data exist, and reproduce it on a secon...

Reproduced Numbers, Unlicensed Claims: Preregistered Acceptance Contracts for Post-Training Compression

Reproducing a published table does not settle whether the sentence it supports was ever specified tightly enough to be accepted or rejected as written. We study that gap through the acceptance contract---the six fields a quality-preservation claim must fix before it is testable (...
