The Power of Domain Randomization
Traditional deep learning in cryo-ET suffers from the 'synthetic-to-real domain gap'. Template Learning addresses this by simulating diverse scenarios, including variations in molecular shape, pose, and experimental conditions. This approach allows models to generalize effectively to real-world data, circumventing the need for labor-intensive, annotated experimental datasets.
Key elements include randomizing object shapes, introducing 'distractor' molecules, and varying rendering parameters like electron dose and defocus, all critical for robust model training.

Case Study: Nucleosome Picking in Mitotic Chromosomes
In a direct comparison for nucleosome annotation in a challenging dataset of partially decondensed mitotic chromosomes, Template Learning outperformed traditional template matching. Our method demonstrated significantly higher precision and, critically, a more uniform orientation detection. This resolves a major issue with template matching, which often exhibits an orientational bias, especially for non-spherical particles.
The ability to train models that pick particles isotropically, without manual curation to eliminate false positives, represents a substantial advancement for downstream structural analysis.
