Reconstructing the 3D articulated shape of an animal from a single in-the-wild image is a challenging task.

A natural generalization is to replace this input setP of n points by a setP of n sets inX. The distance from such an input setP P to a setC of centers can then be defined as the distance between the closest point-center pair. This problem is calledk-mean for sets; see e.g.

Language models have been successfully used to model natural signals, such as images, speech, and music.

Further,inthemiddlestage,i.e. fromthe7thto9thlayers,head tokens draw more attention from other tokens.

Our comparisons show that self-attention is not critical for Vision Transformers, as gMLP can achieve the same accuracy.
