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.
