Note – Paper is presented from the point of view of Few shot learning for multi-
label samples

Methodology
Combine pairs of given examples in feature space, so that the resulting synthesized feature vectors will
correspond to examples whose label sets are obtained through certain set operations on the label sets of the
corresponding input pairs.

More of an
expectation.
Takes content into
consideration
Training process is different. We take
intersection of the labels (albeit in
feature space) and not the content.
What would happen if intersection of
labels if empty set.

Coco Experiments: Classification
The Coco dataset is split into Coco-A(64 classes), Coco-B(16 classes)
in order to evaluate the model on the unseen
categories, they separately train a 16-way classifier
on them, used for evaluation. This is a standard
metric in domain generalization, but it means the
model can not confuse them with already seen
classes, which would be a likely source of errors

Coco Experiments: Retrieval
The Coco dataset is split into Coco-A(64 classes), Coco-B(16 classes)
Their backbone itself seems to be
okish. Would like to see its
performance numbers (guess based
on visual results)
Why IOU now, we
are only bothered
about labels, no?
