Model Architecture and Training
- The article describes a diffusion-based framework that separates the ingredient selection from ingredient quantification in burger recipes.
- The model utilizes a multinomial diffusion model for ingredient selection and a score-based diffusion model for ingredient quantification given a mask.
- This framework progressively randomizes existing recipes into noisy combinations and reverses the process to generate realistic burger recipes.
-
Diffusion-Based Recipe Generation
- A forward stochastic process adds noise to data samples, progressively obscuring the original sample over time steps.
- The reverse stochastic process is learned to progressively denoise the data and reconstruct realistic burger recipes from unstructured noise.
-
Ingredient Selection and Quantification
- Ingredient selection is modeled using a multinomial diffusion process where the presence of an ingredient is treated as a categorical variable.
- Ingredient quantification conditional on a selection mask is estimated using a score-based diffusion model formulated through stochastic differential equations.
-
Dataset and Training Validation
- The model is trained on a dataset derived from human-designed burger recipes, sourced from Food.com, containing 2,216 recipes with 146 ingredients.
- The model accurately reproduces the statistical properties of the training data, estimating ingredient presence and predicting quantities in unseen recipes with small errors.
-
Recipe Validation and Sensory Survey
- AI-generated burgers are prepared and evaluated in a blind sensory survey conducted with 101 participants, assessing overall liking, flavor, and texture on a Likert scale.
- Participants also rate binary flavor- and texture-related attributes. The survey aims to validate the palatability and novelty of the AI-generated recipes compared to a human-designed benchmark, the Big Mac®.
