Sled dogs pull sleds for recreation and work. Sled dogs have been helping humans travel across the planet's coldest regions for centuries, hauling supplies, people, and equipment across the snow and ice. In the process, this important role that goes above and beyond simply being "man's best friend" could have a visible impact on their evolution. Sled dogs may have evolved shorter legs to help them pull loads more efficiently.

But they were both great at getting attention. Public Domain Indeed, academics at the time reportedly sent flustered letters to the editor at calling the prediction "ridiculous" and "manifestly absurd." "There was never, even at that time, any reason to think that it would keep growing fast like that."

Venus flytraps are only native to the coastal bogs, wetlands, and pine savannas of North Carolina and South Carolina in the United States. Anyone who's seen the 1986 musical comedy, is familiar with Audrey II . Audrey II looks like a towering, blood-eating Venus flytrap plant, even mimicking the jaw-like, snapping pod of real carnivorous plants. But while Venus flytraps consume insects, Audrey II feeds on humans.

Domain generalization aims to train models that perform robustly on unseen target domains without access to target data. The realm of vision-language foundation model has opened a new venue owing to its inherent out-of-distribution generalization capability. However, the static alignment to class-level textual anchors remains insufficient to handle the dramatic distribution discrepancy from diverse domain-specific visual features. In this work, we propose a novel cross-domain Schrödinger Bridge (SB) method, namely SBGen, to handle this challenge, which explicitly formulates the stochastic semantic evolution, to gain better generalization to unseen domains. Technically, the proposed SBGen consists of three key components: (1) text-guided domain-aware feature selection to isolate semantically aligned image tokens; (2) stochastic cross-domain evolution to simulate the SB dynamics via a learnable time-conditioned drift; and (3) stochastic domain-agnostic interpolation to construct semantically grounded feature trajectories. Empirically, SBGen achieves state-of-the-art performance on domain generalization in both classification and segmentation. This work highlights the importance of modeling domain shifts as structured stochastic processes grounded in semantic alignment.
