SLIDE 3

Classification results using GCN, with 20 label per class

Cora features visualization

SLIDE 4

What about 1 labeled sample per class?

SLIDE 5

Classification results using GCN, with 1 label per class

Cora features visualization

SLIDE 6

Our solution

Shoestring

SLIDE 7

What we get

Shoestring-cos with 1 label Per class Shoestring-L2 with 1 label Per class

SLIDE 8

Furthermore…

We applied Shoestring to few-shot image classification on miniImageNet and tieredImageNet (5- way).
