Cold start problem

As explained in Building Reliable AI Systems

The difficulty of producing useful recommendations or representations for new items that lack interaction history.

In search, a new listing has no clicks or bookings to shape its embedding, risking poor visibility before it can accumulate interaction data. section 4.2.6

Use a two-stage approach:

Generate an initial embedding from listing descriptions and attributes. section 4.2.6
Re-embed frequently as clicks and bookings accumulate, so new listings can benefit from interaction signals. section 4.2.6
