[[Unsupervised learning|Unsupervised]] capsnets learn a global [[Affine space|linear manifold]] between an object and its pose as a matrix of weights. In other words, capsnets can identify an object independent of its pose, rather than having to learn to recognize the object while including its spatial relationships as part of the object. In capsnets, the pose can incorporate properties other than spatial relationships, e.g., color (cats can be of various colors).

Multiplying the object by the manifold poses the object (for an object, in space).<ref>{{Cite web|url=https://kndrck.co/posts/capsule_networks_explained/|title=Capsule Networks Explained|last=Tan|first=Kendrick|date=November 10, 2017|website=kndrck.co|language=en|archive-url=|archive-date=|dead-url=|access-date=2017-12-26}}</ref>
