Innovative Technology
Our Technologies
Fit Analytics’ solutions are powered by a vast database of garment, size and fit information as well as purchase and return data records. Our sophisticated approach uses machine learning algorithms to help apparel shoppers receive accurate size and fit recommendations, alleviating costly returns for retailers.


Machine Learning Overview
Machine learning, which is a subset of artificial intelligence, is the technology we leverage in our computing system to match the body shapes of Fit Finder users with correctly sized apparel. Our algorithms identify patterns in purchases and returns data, which allows us to deliver personalized recommendations for the items that are most likely to fit shoppers, resulting in happier customers and fewer returns.

Algorithms and Models
Our recommendations are based on closed-loop interaction between data and machine learning within our advanced algorithmic framework. We identify garment sizes and shapes using apparel metadata from our vast database. User inputs and our large body-modeling dataset help us understand body shapes. Advanced machine learning is then used to match products to body shapes based on whether similar users have kept their products. Our frequently updated datasets and models learn, adjust, and improve for future recommendations.
