Vision-Based Outfit Recommendation & Styling Engine

Built a computer-vision and recommendation platform that combines clothing embeddings, attribute tagging, and hybrid ranking logic for personalized outfit generation.

Challenge

AI Wardrobe needed a recommendation system that could reason across visual similarity, style constraints, and user-specific preferences. Rule-only systems lacked personalization depth, while pure embedding similarity produced stylistically inconsistent combinations for real-world occasions.

Solution

Helios developed a hybrid recommendation architecture combining vision embeddings, attribute extraction, FAISS-based nearest-neighbor retrieval, and rule-aware outfit composition. The system tagged catalog items across category, color, material, and occasion dimensions, then merged embedding relevance with business and style rules. A feedback loop captured user interactions to incrementally refine recommendation ranking and personalization quality over time.

Technical Responsibilities

  • Built clothing embedding and feature extraction pipelines for visual understanding
  • Implemented attribute tagging across category, color, material, and occasion
  • Integrated FAISS-based retrieval for high-speed similarity search
  • Designed hybrid ranking combining rule-based logic with embedding relevance
  • Developed personalization feedback loop for ranking refinement
  • Implemented scalable serving APIs for recommendation workflows

Outcomes

  • Consistent and scalable outfit recommendation generation
  • Improved recommendation relevance through hybrid ranking logic
  • Better personalization via iterative user-feedback incorporation
  • Operationally efficient retrieval and serving pipeline for large catalogs
