what would a task2vec (cosine) distance of -1 mean?

I feel -1 would mean the task representations/embeddings point in opposite directions. But the actual vectors are the same. So are the tasks completely similar up to a single bit of info (the sign) or is it better to interpret this that the two tasks are the same and the direction should be ignored?

In general I'm trying to figure how to interpret the negative sign.

I suppose 0 means perpendicular tasks and 1 means the actual same vector -- even the sign.

Start with the Task2Vec paper linked in the repository description and inspect how cosine distance is used in this project. Compare the mathematical definition with the reported vector behavior, then document the intended interpretation of negative values; done when the sign convention and similarity meaning are clearly explained.
