How significant is the decoder part of the capsule network?

Capsule Networks use an encoder-decoder structure, where the encoder part consists of the capsule layers (PrimiaryCaps and DigitCaps) and is also the part of the capsule network which performs the ...

Is the number of neurons in each capsule in a capsule neural network hardcoded?

The capsule neural networks have been formally introduced in the paper Dynamic Routing Between Capsules. Much ado has been made about how the capsules output a vector (magnitude = probability that an ...

Is anyone able to reproduce Hinton's matrix capsule networks?

I've been working on Hinton's matrix capsule networks for several months. I searched each corner of the internet. But I couldn't find anyone that can reproduce Hinton's matrix capsule network. Can ...

How exactly is equivariance achieved in capsule neural networks?

I have read quite a lot about capsule networks, but I cannot understand how the squashed vector would also rotate in response to rotation or translation of the image. A simple example would be helpful....

Why coupling coefficients in capsule neural networks can't be learned by back-propagation?

The paper Dynamic Routing Between Capsules uses the algorithm called "Dynamic Routing Between Capsules" to determine the coupling coefficients between capsules. Why it can't be done by ...

Would it make sense to use together capsule neural neworks and "topic / narrative modeling"?

This is actually something I have been researching a bit on my own. Most movie scripts can be structurally analysed by using writing theory such as Dramatica. Dramatica is based upon a hierarchy of ...

Is the word "pose" used correctly in the paper "Matrix Capsules with EM Routing"?

In traditional computer vision and computer graphics, the pose matrix is a $4 \times 4$ matrix of the form $$ \begin{bmatrix} r_{11} & r_{12} & r_{12} & t_{1} \\ r_{21} & r_{...

Have capsule neural networks been used to NLP problems?

The capsule neural network seems to be a good solution for problems that involve hierarchies. For example, a face is composed of eyes, a nose and ears; a hand is made of fingers, nails, and a palm; ...
