The binary mask is a 0/1 label generated for each record in the dataset, where 1 means keep and 0 means remove, forming a mask vector corresponding one-to-one with the samples for downstream filtering; compared with directly deleting anomalous records, the advantage of the mask is that it is traceable and reversible, facilitating ablation experiments comparing different filtering strategies and making it convenient to record filtering decisions in data version management.

UnverifiedMetadata filtering comes in two forms: pre-filtering, which uses structured fields to narrow the candidate set before vector computation for higher precision; and post-filtering, which recalls the Top-K results first and then filters them out—simpler to implement but potentially leaving insufficient usable results.67% similarUnverifiedMetadata fields need to be explicitly declared as indexable fields at data ingestion time; otherwise, filter operations will degrade to full scans, affecting performance.67% similarUnverifiedReplacing the forget set labels with zero causes the model to learn to predict those samples as class 0, and modifying labels is a different thing from eliminating the influence of samples.66% similarUnverifiedMetadata filtering excludes irrelevant documents before retrieval, both improving precision and reducing downstream computational costs.64% similar
