Description

Similar objects

The following are SFO Museum Aviation Collection object images whose mathematical representations are similar to this image. These representations are referred to as vector embeddings and were derived using a series of different machine-learning models. The definition of similar in the eyes of any given machine-learning model is often opaque, typically mysterious and sometimes incorrect. As such these objects are included because they are generally similar in nature, or spirit, and as a way to help you discover things in our collection which you might have otherwise missed.
