Zatom-1: A Multimodal Flow Foundation Model for 3D Molecules and Materials

arXiv:2602.22251v1 Announce Type: new Abstract: General-purpose 3D chemical modeling encompasses molecules and materials, requiring both generative and predictive capabilities. However, most existing AI approaches are optimized for a single domain (molecules or materials) and a single task (generation or prediction),…

Symmetry in language statistics shapes the geometry of model representations

arXiv:2602.15029v2 Announce Type: replace Abstract: The internal representations learned by language models consistently exhibit striking geometric structure: calendar months organize into a circle, historical years form a smooth one-dimensional manifold, and cities’ latitudes and longitudes can be decoded using a…

Sustainable LLM Inference using Context-Aware Model Switching

arXiv:2602.22261v1 Announce Type: new Abstract: Large language models have become central to many AI applications, but their growing energy consumption raises serious sustainability concerns. A key limitation in current AI deployments is the reliance on a one-size-fits-all inference strategy where…

LinGuinE: Longitudinal Guidance Estimation for Volumetric Tumour Segmentation

arXiv:2506.06092v2 Announce Type: replace-cross Abstract: Longitudinal volumetric tumour segmentation is critical for radiotherapy planning and response assessment, yet this problem is underexplored and most methods produce single-timepoint semantic masks, lack lesion correspondence, and offer limited radiologist control. We introduce LinGuinE…

Entropy-Controlled Flow Matching

arXiv:2602.22265v1 Announce Type: new Abstract: Modern vision generators transport a base distribution to data through time-indexed measures, implemented as deterministic flows (ODEs) or stochastic diffusions (SDEs). Despite strong empirical performance, standard flow-matching objectives do not directly control the information geometry…

The Spacetime of Diffusion Models: An Information Geometry Perspective

arXiv:2505.17517v4 Announce Type: replace Abstract: We present a novel geometric perspective on the latent space of diffusion models. We first show that the standard pullback approach, utilizing the deterministic probability flow ODE decoder, is fundamentally flawed. It provably forces geodesics…

Simplex-to-Euclidean Bijections for Categorical Flow Matching

arXiv:2510.27480v2 Announce Type: replace Abstract: We propose a method for learning and sampling from probability distributions supported on the simplex. Our approach maps the open simplex to Euclidean space via smooth bijections, leveraging the Aitchison geometry to define the mappings,…
