A Self-Supervised Learning Pipeline with Open-Set Detection and Quality Assessment for Embryonic Lineage Classification from scRNA-seq

Single-cell RNA sequencing enables high-resolution analysis of early embryonic lineage specification, but most computational pipelines reduce the task to closed-set TE/ICM classification and discard uncertain cells before training. This practice can inflate apparent accuracy while removing the cells most relevant for t...

World Models for Cross-Machine CNC Transfer under Partial Sensor Overlap

This study asks whether a command-conditioned latent world model, trained to predict future representations of the process rather than to reconstruct future samples, keeps its value on a machine it has never seen: a source CNC machine exposes 17 sensor channels, the target sharing 10 of those.

What Do Medical Vision-Language Models Learn in Radiology? Transfer, Alignment, and Source-Proxy Leakage Under Distribution Shift

The study shows that apparent competence under a single protocol can conceal transfer, alignment, and shortcut-related failure modes, motivating stress-tested evaluation of medical VLMs under distribution shift.
