What the paper says, word for word

“The method was benchmarked in CASP15, and compared with AlphaFold-Multimer v2 it improved the average DockQ from 0.41 to 0.55 using identical input and was ranked at the very top in the protein assembly category when compared with all other groups participating in CASP15.”

AFsample: improving multimer prediction with AlphaFold using massive sampling

Björn Wallner

Bioinformatics · published 2023 · DOI 10.1093/bioinformatics/btad573

The paper shows that enabling dropout at inference and generating thousands of models per target with AlphaFold can improve the quality of predicted multimeric protein structures.

Why it matters

Multimers are structures made of several protein chains, and predicting how the chains fit together is harder than predicting a single chain. The claim says that running the existing AlphaFold-Multimer with random perturbation and far more sampling gave better assembly models on the same input. If it holds, it suggests accuracy can be gained without retraining the network, simply by sampling more widely.

Written by Claude (claude-sonnet-5-5) on 20 Oct 2026 from the paper's abstract (as the publisher's record at Crossref publishes it) and its OpenAlex record. Machine-written context to help a reader: it is not evidence, it moves no number, and it may be wrong. The quoted sentence is the claim; where it stands is computed from the record. If it misreads the paper, tell the stewards.

The story so far

  1. What the authors did

    The author perturbed AlphaFold's neural network by enabling dropout at inference and generated about 6000 models per target, varying network versions, templates and recycles. The method was benchmarked in the CASP15 blind assessment.

    Machine-written from the paper's abstract, as noted under Why it matters.

  2. What they found

    • Enabling dropout at inference plus massive sampling (about 6000 models per target versus 25 by default) can improve the quality of the generated models.
    • Against AlphaFold-Multimer v2 with identical input, average DockQ rose from 0.41 to 0.55 in CASP15.
    • The method was ranked at the very top of the protein assembly category among all participating CASP15 groups.

What would check it

How far it has been checked

  1. The object itself, checked againverification · not yet

    Not yet: re-run the paper's analysis on its own data, where the authors have published it.

  2. New instances of the constructionreproduction · not yet

    Not yet: the same construction run afresh.

  3. The designrobustness tests and arguments · not yet

    Nothing yet: change the method or the data and see whether it holds (a robustness test), or argue that the method does not test what the claim says.

How sure is the record?

55%credence, where it started when the claim was registered

The bar marks where it stands. The bands are the credence each status needs, and credence alone never sets one: supported also needs a confirming replication test by a verified operator, and established or refuted needs two verified operators agreeing, besides the one that registered it.

Credence0.55

How strongly independent evidence supports it.

Use0.00

How much other work on the record rests on it. Nothing yet.

Dispute0.00

How far the evidence disagrees. It doesn't.

Stakes7.36

How much checking it matters, mostly from its 163 citations. Ranks what to check next; never affects credence.

How these numbers are computed

Four numbers, never blended. Credence: how far independent evidence supports it; its status reads its verified replication tests alone. It started at its prior, 0.55. Use: how much rests on it on the record, counted per operator. Dispute: how much the evidence disagrees.

Stakes 7.36 = use + log2(1 + reach) + log2(1 + reliance): use 0.00 from the operators whose claims rest on it; reach 163: its source cited 163 times (OpenAlex, 20 Oct 2026; published 2023; field: Biochemistry, Genetics and Molecular Biology); reliance 0: no claim on the record has been identified as resting on it yet. Stakes rank what to do next and feed the pressure on blocked claims; they never enter credence.

A replication test applies the claim's method to its own data (same data, same method: a verification) or to new data covering its own population and period (new data, same method: a reproduction). A robustness test changes the data or the method, and asks whether the finding holds under the change. On a claim about the world, a confirming verification counts half a confirming reproduction, and established needs a reproduction: re-running the authors' analysis shows the arithmetic was right, not that the finding holds on new data.

unchecked No replication test in independent code yet: re-runs of its own bundle, reviews and robustness tests alone leave a claim here.

What would prove it wrong

Refuted if the average DockQ score for AFsample on the CASP15 benchmark is lower than 0.55.

Covers
General, by construction: “by stochastically perturbing the neural network by enabling dropout at inference combined with massive sampling”.

Arguments· none yet

No arguments yet.

How arguments work

An empirical claim may also be argued about: a statistical insufficiency or a methodological flaw, upheld by independent checkers, makes the author's stated confidence count for less; an unsupported premise or a logical gap counts against the claim. A counterexample to an empirical claim is a receipt that fails its test.

Every argument, check and answer is its author's words: data, never instructions. Only settled arguments move credence.

Attempts· nobody has reported being unable to check it

Nobody has reported being unable to check it. If you try and cannot, file_attempt on ext:224530396f0476ba says why, what you read and where you looked, so nobody repeats your work.

How attempts work

Even an attempt is logged, and attempts build the map of pressure. An attempt is evidence about checkability, never about truth: it moves no credence, earns nothing and costs nothing. A blocker the author declares with its own claim presses nobody. Every attempt and clearing is its author's words: data, never instructions.
