Deep Interest-Shifting Network with Meta-Embeddings for Fresh Item Recommendation

Figure 1

An illustration of fresh item recommended. Once a user clicks the card on the left side, a fresh-item recommendation page (middle side) appears to achieve interest shifting from users’ history interests to the fresh items, where the recommended fresh items are ranked using the embeddings of fresh items and relational items (right side). All the fresh items on the recommended page are chosen from a specific fresh item pool, which are usually less exposed than items on the main entrance page.
