Visually-Aware Fashion Recommendation and Design with Generative Image Models
This work addresses the challenge of subjective and complex fashion recommendation for users, offering a step towards generative design systems, though it builds incrementally on prior visual recommendation techniques.
The paper tackles the problem of improving fashion recommendation by learning fashion-aware image representations jointly with the recommender system, showing significant performance improvements over state-of-the-art methods like BPR, and demonstrates the model's generative capability to create new clothing images based on user preferences.
Building effective recommender systems for domains like fashion is challenging due to the high level of subjectivity and the semantic complexity of the features involved (i.e., fashion styles). Recent work has shown that approaches to `visual' recommendation (e.g.~clothing, art, etc.) can be made more accurate by incorporating visual signals directly into the recommendation objective, using `off-the-shelf' feature representations derived from deep networks. Here, we seek to extend this contribution by showing that recommendation performance can be significantly improved by learning `fashion aware' image representations directly, i.e., by training the image representation (from the pixel level) and the recommender system jointly; this contribution is related to recent work using Siamese CNNs, though we are able to show improvements over state-of-the-art recommendation techniques such as BPR and variants that make use of pre-trained visual features. Furthermore, we show that our model can be used \emph{generatively}, i.e., given a user and a product category, we can generate new images (i.e., clothing items) that are most consistent with their personal taste. This represents a first step towards building systems that go beyond recommending existing items from a product corpus, but which can be used to suggest styles and aid the design of new products.
