Its usefulness depends on whether that local approximation predicts well, which the formulation alone cannot show. - [What an Elephant Minus Horse Vector Says](https://agi.technocraftai.com/what-an-elephant-minus-horse-vector-says/): The difference between elephant and horse embeddings can be drawn as a direction in semantic space. That direction suggests a route for extrapolation, but is not evidence that an unseen class will be recognized. - [From Edges to Unseen Object Classes](https://agi.technocraftai.com/from-edges-to-unseen-object-classes/): An object representation built from edges, corners, and formal parts has a natural connection to compositional zero-shot learning. The connection is structural; it does not, by itself, establish recognition performance. ## Pages - [About](https://agi.technocraftai.com/about/) - [Home](https://agi.technocraftai.com/) [comment]: # (Generated by Hostinger Tools Plugin)
