scDataset: scalable data loading for deep learning in single-cell omics

The exponential growth of single-cell genomic data has led to datasets that exceed available memory, forcing information to be loaded directly from disk during deep learning model training. The need for random sampling to preserve minibatch diversity clashes with the inefficiency of random access, while sequential reading, although fast, introduces biases that degrade performance. This technical dilemma has become a bottleneck for biomedical research and the development of new therapies. In response, strategies such as block sampling combined with batch preloading have emerged, achieving a balance between I/O speed and statistical diversity. This approach, similar to that used by certain advanced data loaders, can accelerate training by several orders of magnitude without sacrificing model quality. For companies working with large volumes of data, having optimized infrastructures is key. At Q2BSTUDIO we offer AI for businesses that integrates efficient data processing, whether in cloud or on-premises environments. Our AWS and Azure cloud services ensure scalability and performance in intensive workloads. Additionally, we develop custom applications and custom software tailored to each organization's specific needs, including data pipelines for artificial intelligence and AI agents. Managing data diversity is not just an academic problem; it is also faced by areas such as cybersecurity, where anomaly detection requires representative sampling, or business intelligence, where tools like Power BI need up-to-date and unbiased data. Therefore, our business intelligence services solutions cover everything from extraction to visualization, ensuring that every decision is based on reliable information. Ultimately, the combination of intelligent sampling techniques with a solid technological platform allows organizations to extract the full potential of their data, as demonstrated in the field of single-cell omics with scalable loading systems.
