Epicure: Multidimensional Flavor Structure in Food Ingredient Embeddings

Jakub Radzikowski, Josef Chen · 2026

A chef's intuition about flavor, texture, and cultural identity represents tacit knowledge that is difficult to articulate yet central to culinary practice. We show that this knowledge is already enco…

Beyond the Largest Lyapunov Exponent: Entropy-Based Diagnostics of Chaos in Henon-Heiles and N-Body Dynamics

Alessandro Alberto Trani, Pierfrancesco Di Cintio, Michele Ginolfi · 2026

The largest Lyapunov exponent is widely used to diagnose chaos in gravitational dynamics, but in mixed phase spaces and finite-N systems it does not always provide a complete description of orbital co…

A visual observation on the geometry of UMAP projections of the difference vectors of antonym and synonym word pair embeddings

Rami Luisto · 2026

Antonyms, or opposites, are sometimes defined as \emph{word pairs that have all of the same contextually relevant properties but one}. Seeing how transformer models seem to encode concepts as directio…

The Separating Noether Number of Finite Abelian Groups

Jing Huang · 2026

For a finite abelian group $G$, let $\beta_{\mathrm{sep}}(G)$ denote its separating Noether number. We determine $\beta_{\mathrm{sep}}(G)$ exactly for every finite abelian group $ G \cong C_{n_1}\oplu…
