SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

NeMo Curator removes the slow, manual work of preparing large training datasets by filtering low-quality content, deduplicating near matches, redacting sensitive data, and scaling the whole workflow across GPUs.

Core Features & Use Cases

  • Quality Filtering: Apply 30+ heuristics to remove short, repetitive, noisy, or low-value documents before training.
  • Deduplication: Handle exact, fuzzy, and semantic duplicates to reduce redundancy in web-scale corpora.
  • Multimodal Curation: Work with text, images, video, and audio datasets for LLM and multimodal model preparation.
  • Privacy and Safety: Redact PII and screen for NSFW or otherwise unsafe content during dataset cleanup.
  • Use Case: A data team can take raw Common Crawl exports, filter them for quality, deduplicate them, redact personal information, and export a cleaner parquet dataset for model training.

Quick Start

Use the nemo-curator skill to clean a parquet dataset by filtering low-quality records, removing duplicates, and redacting any sensitive information.

Frequently Asked Questions about nemo-curator

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

FAQPage Schema
How do I clean and deduplicate large-scale LLM training datasets efficiently?▼

To clean and deduplicate large-scale LLM training datasets, apply GPU-accelerated quality filtering, exact and semantic duplicate removal, and PII redaction across text, image, video, and audio corpora to yield deterministic high-throughput curation.

What is GPU-accelerated data curation for multimodal model preparation?▼

GPU-accelerated data curation for multimodal model preparation is the process of using RAPIDS and Dask-based scaling to filter, classify, and embed text, image, video, and audio datasets for deterministic high-throughput cleaning.

Can I redact PII and screen for NSFW content during web crawl curation?▼

Yes, you can redact PII and screen for NSFW content during web crawl curation by applying privacy and safety filters alongside 30+ quality heuristics to remove low-value documents before training.

Does data deduplication work with both exact and fuzzy matches in web-scale corpora?▼

Yes, data deduplication handles exact, fuzzy, and semantic duplicates to reduce redundancy in web-scale corpora, utilizing distributed GPU processing and filter, classifier, and embedding workflows.

Do I need RAPIDS and Dask to scale dataset quality filtering across GPUs?▼

Yes, you need RAPIDS-powered GPU acceleration and Dask-based scaling to execute filter, classifier, and embedding workflows for deterministic high-throughput dataset quality filtering across large corpora.

When should I not use GPU acceleration for dataset cleaning?▼

You should not use GPU acceleration for dataset cleaning if your training data is small-scale, lacks multimodal complexity, or does not require the high-throughput distributed processing needed for web crawl curation.
