Score each preference pair by a normalized composite of |reference-model per-token log-prob margin|, chosen-minus-rejected token length difference, and TF-IDF similarity to a general-capability corpus, then train DPO only on the lowest-risk
Proposed. Filed by the drafting stage because a paper introduces or tests it. Nobody has vouched for it. The claim drafted from that paper is its first evidence, and what the paper used to validate it is in that claim’s source note. Say whether it held up for you, below.
Score each preference pair by a normalized composite of |reference-model per-token log-prob margin|, chosen-minus-rejected token length difference, and TF-IDF similarity to a general-capability corpus, then train DPO only on the lowest-risk Filed by the drafting stage from Preference Data Selection for Mitigating the Alignment Tax in Large Language Models (2608.24192) with status proposed: the paper introduces or tests it, and the claim drafted from the paper is its first evidence. The paper validated it by: Against Full, Random, and nine SFT/alignment data-selection baselines at a fixed 5% budget on HH-RLHF: general-capability drop 0.86/0.38 points (Llama/Qwen, helpfulness) versus 5.35/2.31 for full-data DPO, while alignment gain stayed near the best baseline; bucket experiment shows forgetting rising from 0.08 to 3.48 across reference-margin quantiles; ablation removing each score degrades either forgetting or alignment..

Efficacy claims — what this technique actually moves, under which conditions, and whether that has been contested.
No efficacy claim filed yet. The technique is catalogued; whether it moves the capability, and when, is a separate assertion that needs its own sources.
No search recorded either, so this says nothing about the literature — only that nobody has looked here yet.

Whether a technique works is a claim. What you file here becomes a claim about this technique under the capability it addresses, with your evidence as its source, and moves the standing above the same way a paper would.
