Research direction

Edit docs/wiki-guide/Glossary-for-Imageomics.md and first review nearby glossary entries for formatting and level of detail. Add the proposed Data Leakage term with its Imageomics-specific context and references, then check the rendered Markdown and links. Done means the glossary entry is clear, consistent with surrounding terms, and correctly cited.

Description

Proposed glossary item

Data Leakage

In machine learning, data leakage occurs when information that would not be available at prediction time influences model building or evaluation, yielding overly optimistic performance estimates. In Imageomics datasets, leakage can occur when duplicate images or multiple views or records of the same biological specimen are divided between training and evaluation; keep all records with the same specimen identifier in one split.

This proposed definition is based on the Imageomics data-workshop onboarding lesson and is intended for docs/wiki-guide/Glossary-for-Imageomics.md.
