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?

You can deduplicate large-scale multimodal datasets using GPU-accelerated exact, fuzzy, and semantic deduplication. Nemo-curator processes text, image, video, and audio sources to produce high-quality, filtered training data for LLMs.

Does GPU-accelerated data curation require NVIDIA RAPIDS and compatible GPUs?

Yes, GPU-accelerated data curation requires the NVIDIA RAPIDS stack and compatible GPUs. Nemo-curator leverages this environment to perform multi-GPU scaling for large datasets like RedPajama and The Pile.

What is the best way to filter NSFW content and redact PII from web-scraped corpora?

The best way to filter NSFW content and redact PII from web-scraped corpora is using built-in detection modules. Nemo-curator includes NSFW detection and PII redaction features during the multimodal data curation pipeline.

Can I use multi-GPU scaling to preprocess web-scraped corpora for LLM benchmarks?

Yes, you can use multi-GPU scaling to preprocess web-scraped corpora for LLM benchmarks. Nemo-curator supports scalable, multi-GPU workflows designed for large-scale data curation tasks across text, image, video, and audio sources.

How does semantic deduplication work for multimodal training data?

Semantic deduplication works by identifying and removing contextually similar data points across modalities. Nemo-curator applies GPU-accelerated semantic, fuzzy, and exact deduplication to ensure high-quality training data.

When should I not use GPU-accelerated deduplication for my training data?

You should not use GPU-accelerated deduplication if your environment lacks NVIDIA RAPIDS stack support or compatible GPUs. Nemo-curator is designed for large-scale multimodal data curation and requires specific GPU hardware to function.
