Interpretable Fashion Matching with Rich Attributes

Understanding the mix-and-match relationships of fashion items receives increasing attention in fashion industry. Existing methods have primarily utilized the visual content to learn the visual compatibility and performed matching in a latent space. Despite their effectiveness, these methods work like a black box and cannot reveal the reasons that two items match well. The rich attributes associated with fashion items, e.g.,off-shoulder dress and black skinny jean, which describe the semantics of items in a human-interpretable way, have largely been ignored. This work tackles the interpretable fashion matching task, aiming to inject interpretability into the compatibility modeling of items. Specifically, given a corpus of matched pairs of items, we not only can predict the compatibility score of unseen pairs, but also learn the interpretable patterns that lead to a good match, e.g., white T-shirt matches with black trouser. We propose a new solution named A ttribute-based I nterpretable C ompatibility (AIC) method, which consists of three modules: 1) a tree-based module that extracts decision rules on matching prediction; 2) an embedding module that learns vector representation for a rule by accounting for the attribute semantics; and 3) a joint modeling module that unifies the visual embedding and rule embedding to predict the matching score. To justify our proposal, we contribute a new Lookastic dataset with fashion attributes available. Extensive experiments show that AIC not only outperforms several state-of-the-art methods, but also provides good interpretability on matching decisions.
