The Lottery Ticket Hypothesis for Vision Transformers. (arXiv:2211.01484v1 [cs.CV])

The conventional lottery ticket hypothesis (LTH) claims that there exists a
sparse subnetwork within a dense neural network and a proper random
initialization method, called the winning ticket, such that it can be trained
from scratch to almost as good as the dense counterpart. Meanwhile, the
research of LTH in vision transformers (ViTs) is scarcely evaluated. In this
paper, we first show that the conventional winning ticket is hard to find at
weight level of ViTs by existing methods. Then, …
