Relevant data fields
The fields most relevant here span several groups in our schema reference: ingredients, ingredients_formatted, and inci_format from Ingredients; average_rating and number_of_reviews from Reviews & Ratings; category_1/2/3, brand_name, and description from Product Info; and price, original_price, and timestamp from Pricing & Availability for any model with a temporal or demand-forecasting component.
As noted on our ingredient formatting page, normalization is continuously improved but not guaranteed to be perfect on every record — worth accounting for with standard data-quality checks in a training pipeline, the same as you would for any external data source.
