The Personalization & Relevance team at OLX is increasing transactions between buyers and sellers by showing the most relevant content to our users. We are developing personalization technologies and optimization strategies that fuel the discovery of new items and have a direct impact on OLX’s bottom line. A picture is worth a thousand words: OLX is a gold mine for unique hard to find items. While sellers often use few words to describe the items they are selling, many buyers find it hard to formulate their intent into a search query. We are researching deep learning techniques to enable users to visually search through millions of items by either taking a photo or using any image online as a search query.

Implement a search algorithm that finds visually similar images. Two main challenges of the project are

  • the solution shall learn similarity metrics;
  • the solution shall provide efficient instance retrieval.
