Epicure: Navigating the Emergent Geometry of Food Ingredient Embeddings
This presentation explores Epicure, a family of multilingual food ingredient embeddings built from 4.14 million recipes across seven languages. The talk demonstrates how controlling the balance between recipe co-occurrence and flavor chemistry during embedding construction creates distinct, navigable geometries that support practical culinary operations—from intelligent ingredient pairing and substitution to cross-cuisine exploration—while revealing how computational methods can capture and expose the hidden structure of global food culture.Script
When you embed 4.14 million recipes from seven languages into a shared geometric space, something remarkable emerges: ingredients self-organize into culinary neighborhoods you can actually navigate.
The authors built three distinct embedding models by changing just one design lever: the random walk template. Cooc follows recipe co-occurrence, Chem navigates flavor compound graphs, and Core blends both signals, creating three different lenses on the same culinary knowledge.
Without any explicit cuisine labels during training, the Chem model achieves a Cohen's d of 3.07 for separating macro-regional cuisines. The geometry itself has learned to encode cultural boundaries purely from the chemistry of shared flavor compounds.
Epicure exposes a powerful navigation primitive called SLERP rotation. Rotate rice toward the South Asian pole and you surface dal and ghee; rotate corn toward Latin America and tomatillo and queso fresco emerge. The angle controls how far you travel from familiar to contextually appropriate.
The same operation reveals the models' fundamental difference. Rotating chocolate toward sweet baking yields vanilla and butter in Cooc, but red bean and matcha in Chem, because chemistry-driven walks privilege flavor profiles over regional co-occurrence patterns.
By making the chemistry versus recipe context axis explicit and controllable, Epicure transforms embedding design into a practical tool for culinary exploration. Visit EmergentMind.com to learn more about this work and create your own video summaries of cutting-edge research.
