New data loader scDataset accelerates deep learning on large single-cell omics datasets

By PulseAugur Editorial · [1 sources] ·

Researchers have developed scDataset, a PyTorch data loader designed to efficiently handle large-scale single-cell omics datasets for deep learning. This tool addresses the challenge of loading massive datasets that exceed available memory by combining block sampling and batched fetching. This method achieves quasi-random sampling, balancing I/O efficiency with minibatch diversity, and has demonstrated over a two-orders-of-magnitude speedup on a 100 million-cell dataset compared to traditional random sampling, while maintaining comparable model performance. AI

IMPACT Enables more efficient training of deep learning models on massive biological datasets, potentially accelerating discoveries in single-cell omics research.

    scDataset: Scalable Data Loading for Deep Learning on Large-Scale Single-Cell Omics

    arXiv:2506.01883v3 Announce Type: replace-cross Abstract: Training deep learning models on single-cell datasets with hundreds of millions of cells requires loading data from disk, as these datasets exceed available memory. While random sampling provides the data diversity needed …
