Web5 okt. 2024 · 1 Answer Sorted by: 6 Upon some reflection, the answer is that no, they most definitely do not. The easiest way to see this is to observe that there are d 2 − 1 orthogonal directions in the Bloch representation ( i.e. orthogonal Hermitian traceless operators) containing pure states. WebIn this work, we identify two key properties related to the contrastive loss: (1) alignment (closeness) of features from positive pairs, and (2) uniformity of the induced distribution of the (normalized) features on the hypersphere.
