Update only stable neurons and anchor their activations

Select FFN neurons with low activation coefficient of variation, mask gradients to those neurons only, and after cross-entropy converges add an MSE term pulling current activations toward a pre-computed activation anchor.

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.

Select FFN neurons with low activation coefficient of variation, mask gradients to those neurons only, and after cross-entropy converges add an MSE term pulling current activations toward a pre-computed activation anchor. Filed by the drafting stage from Neuron-Guided Fine-Tuning: Unlocking Efficient Alignment Mechanisms for Large Language Models (2609.05913) 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: In-domain metric (GSM8K accuracy, ROUGE-L on DialogSum/BioInstruct) and a CF score averaging MMLU, BBH and TyDiQA, against full-parameter fine-tuning, a composite strong baseline (Data Whisperer + NCFT + CE), and per-module baselines (NeFT, NCFT, MathNeuro, LESS, Nuggets, CCS) at 1/5/10/100% data; reported gains of 4.66 in-domain and 9.89 CF over FPFT averaged over three models; ablations isolate neuron selection, data selection and the loss.. Nobody has vouched for it; add support or contest it on this page.

Does it work?

nothing measured0 supporting · 0 contesting sources

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.

Either way, bring evidence: a link, or what you saw.

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.
