Bilimsel iş akışlarında yapay zekâ

Machine learning now enters science at every step: screening literature, designing experiments, analysing images and sequences, emulating simulations and drafting text. Each use can speed discovery and each can introduce errors that look like findings. This page sets out how models are evaluated for scientific use, where leakage, benchmark overfitting and silent drift arise, and what evidence editors, funders and regulators need before they rely on a model-assisted result.

AI in scientific workflows: how the risk develops.

Model evaluation and scientific assistance. The dossier below sets out how the risk develops, what is measured, where the data come from, how it is modelled and who decides.

Mekanizma

Leakage inflates performance

When information from the test set reaches training, through duplicates, shared patients, neighbouring sites or preprocessing fitted on all the data, a model appears more accurate than it is. Leakage has been documented in many fields that adopted machine learning.

Mekanizma

Benchmarks get overfitted

Repeated tuning against the same public benchmark selects models that fit its quirks. Gains on a leaderboard can vanish on new data, and contamination of training corpora with benchmark items makes scores hard to interpret.

Mekanizma

Drift and distribution shift

Instruments, protocols, populations and software change. A model validated on last year’s data or another lab’s scanner can degrade without any visible error. Monitoring after deployment is part of the evaluation, not an extra.

Mekanizma

Generated text and fabricated sources

Language models can produce fluent text, citations and code that are wrong. Unchecked, these errors enter manuscripts, peer reviews and proposals, and spread through citation. Disclosure and verification policies exist because such errors are hard to see.

08Temel sorular

What experts ask about AI in research.

  • What task is the model doing, and what is it compared against?
  • Was the model evaluated on data independent of the data it was trained or tuned on?
  • How does performance change when conditions shift away from the training data?
  • Can the output be checked by a person or a simpler method, and is it?
  • Which steps of the workflow were assisted, and is that disclosed in the result?
09Mekanizmalar ve etkenler

Where AI helps and where it misleads.

Machine learning models learn statistical regularities from data. They can be very effective where those regularities are stable and data are plentiful, for example classifying land cover from satellite imagery or emulating a climate model to explore many scenarios. They are weaker where data are sparse, where the system changes over time or where rare events matter most, which describes much of risk science.

Common failure modes are well understood: leakage, where information from the test set reaches training; dağılım kayması, where conditions in use differ from those in training; shortcut learning, where a model relies on a spurious cue; and overconfident outputs without calibrated uncertainty. Generative models add the risk of fluent but fabricated content, including citations and code that looks correct but is not.

Workflow effects matter as much as model accuracy. When a tool is used at several stages, small errors can accumulate, and reviewers may give automated outputs more trust than they deserve.

10Yöntemler ve veriler

How AI tools are evaluated.

  1. 01

    Held-out and out-of-distribution tests

    Evaluation on data separated by time, place or source. This is the minimum for any claim of generalisation.

  2. 02

    Baselines

    Comparison with simple statistical methods and expert judgement. A complex model that does not beat a simple baseline is not adding value.

  3. 03

    Calibration and uncertainty

    Checks that stated confidence matches observed accuracy, using belirsizlik ölçümü.

  4. 04

    Provenance and disclosure

    A record of which model, version and prompts or settings were used at each step, so the workflow can be re-run or audited.

Benchmark scores rarely transfer directly to a new research setting, and a model’s behaviour can change between versions. Evaluation is repeated when either the task or the model changes.

13Sorular

Sorular ve yanıtlar.

What is data leakage?
Any route by which information about the test data influences training or model selection. It makes reported performance higher than the model will achieve on genuinely new data.
Is a high benchmark score enough to publish a method?
Not on its own. Reviewers increasingly expect external validation, uncertainty on the score, ablations and an account of how the benchmark was protected from contamination.
Can a generative AI tool be listed as an author?
COPE and the ICMJE say no, because authorship carries accountability a tool cannot hold. Use of such tools is disclosed in the methods or acknowledgements, under the journal’s policy.
Why publish model weights and code?
So others can rerun the evaluation, test on new data and find errors. Where weights cannot be shared, for privacy or safety, a controlled access route and a stated reason are the accepted alternative.
Does Labs use generative AI to write findings?
Any assisted step is designed to be disclosed. Findings are the responsibility of named researchers, who check every generated claim, citation and line of code.
Can Labs evaluate a commercial AI model?
A model can be evaluated under a published protocol. The result describes performance on the tested task and is not an endorsement or approval.
Why compare with simple baselines?
Because complex models often appear impressive on benchmarks but add little over a well-chosen simple method on real research data.
