SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires nemo-curator, cudf, dask, rapids, and includes references (resource) components.

What problem does it solve?

NeMo Curator helps you clean and deduplicate large-scale web and multimodal datasets so LLM training data is higher quality, less redundant, and safer.

Core Features & Use Cases

  • GPU-accelerated curation pipeline for text, images, video, and audio, enabling fast preprocessing at scale.
  • Fuzzy and semantic deduplication to remove exact, near-duplicate, and meaning-level duplicates using GPU-friendly approaches.
  • Quality filtering, PII redaction, and NSFW detection to reduce low-quality, unsafe, and sensitive-content contamination before training.
  • Common use case: preparing curated corpora from web scrapes (e.g., Common Crawl) before training or fine-tuning a multimodal LLM.

Quick Start

Use the NeMo Curator Skill to run GPU-accelerated quality filtering, fuzzy deduplication, and PII redaction over your Parquet dataset and write the curated output to a new Parquet directory.

Frequently Asked Questions about nemo-curator

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I deduplicate large-scale multimodal datasets for LLM training?▼

Deduplicate large-scale multimodal datasets by applying GPU-accelerated fuzzy and semantic deduplication to remove exact, near-duplicate, and meaning-level matches from text, image, video, and audio data.

What is the best way to redact PII and filter unsafe content from Common Crawl data?▼

Redact PII and filter unsafe content from Common Crawl data by running GPU-accelerated quality filtering, PII redaction, and NSFW detection to reduce low-quality and sensitive-content contamination.

Can I use RAPIDS and Dask for GPU-accelerated data curation?▼

Yes, you can use RAPIDS and Dask for GPU-accelerated data curation to meet distributed processing and performance needs when curating web-scale multimodal corpora.

Do I need Parquet datasets to run quality filtering and deduplication?▼

You need Parquet datasets to run GPU-accelerated quality filtering and fuzzy deduplication, writing the curated output to a new Parquet directory for downstream LLM training.

Does GPU data curation support preprocessing pipelines for text, image, video, and audio?▼

GPU data curation supports preprocessing pipelines for text, image, video, and audio, enabling fast multimodal quality screening and large-scale deduplication before LLM fine-tuning.

When should I use fuzzy deduplication instead of exact deduplication for LLM training data?▼

Use fuzzy deduplication instead of exact deduplication to remove near-duplicates and meaning-level matches, ensuring LLM training data is less redundant and higher quality.
