 Some operations can be found in cortical layers, but they do not seem to relate this technique.The pose vector formula_1 is rotated and translated by a matrix formula_2 into a vector formula_3 that predicts the output of the parent capsule.Capsules formula_5 in the next higher level are fed the sum of the predictions from all capsules in the lower layer, each with a coupling coefficient formula_6

The coupling coefficients from a capsule formula_8 in layer formula_9 to all capsules in layer formula_10 sum to one, and are defined by a "routing softmax".
