Xtool Dedup: Parameter Patched

Enter — a powerful command-line toolkit for dataset processing. One of its most critical (and often misunderstood) flags is the dedup parameter.

"text": "Paris is the capital of France." "text": "France's capital city is Paris." "text": "The capital of France is Paris." keeps all three (they are not identical strings). Fuzzy dedup (threshold 0.8) → keeps only one representative example, saving you from bloating your training set with redundant information. Critical Parameters That Work With dedup To get the most out of dedup , combine it with: xtool dedup parameter

| Parameter | Purpose | |-----------|---------| | --field text | Only deduplicate based on the text field, ignoring metadata like id or timestamp . | | --minhash | Enable MinHash for fast fuzzy deduplication on huge datasets (millions+ rows). | | --keep first | Keep the first occurrence; discard later duplicates. | | --report | Generate a dedup_report.json showing how many duplicates were removed. | Enter — a powerful command-line toolkit for dataset

When preparing datasets for large language model (LLM) training or fine-tuning, duplicate data is the silent killer . It wastes compute, causes overfitting, and skews your model’s understanding. Fuzzy dedup (threshold 0
