Improving Atlas-Scale Single-Cell Annotation Models with Hierarchical Cross-Entropy Loss
Unlocking Precision in Single-Cell Annotation
Traditional computational models for single-cell RNA sequencing often miss the intricate, hierarchical relationships between cell types, leading to suboptimal performance, especially with new, unseen data. This analysis reveals a novel hierarchical cross-entropy (HCE) loss function that aligns model objectives with biological structure, significantly boosting out-of-distribution performance by 12-15% without increased computational cost. It highlights that improved connectivity between annotated cell types, rather than just model complexity, is key to more generalizable algorithms.
Quantifiable Impact for Your Enterprise
The integration of Hierarchical Cross-Entropy loss into your enterprise AI models for single-cell analysis can unlock unprecedented levels of accuracy and generalizability, particularly when dealing with diverse and evolving biological datasets. This innovation minimizes costly manual re-annotation efforts and accelerates drug discovery and biomarker identification by providing more reliable cell-type classifications.

Impact on Atlas-Scale Cell Type Annotation
The new HCE loss was applied to models ranging from linear classifiers to transformers, demonstrating consistent improvements across architectures. This is critical for atlas-scale projects like the Human Cell Atlas, where new studies are continuously added. The method particularly excels in densely connected regions of the cell ontology, amplifying generalization capabilities where data connectivity is high. This approach means that future efforts should prioritize data generation that improves connectivity among cell types, moving beyond just increasing dataset size.
