In order to gain some intuition about the uniform distribution of orthogonal matrices V, it is useful to recognize that each orthogonal matrix corresponds to the rotation of a vector by a given angle. In a space of dimension M, the rotation is defined by specifying the values of M-1 angles, where ea ...

The basic modification rule in each case is Hebb-like; i.e. change in synaptic strength is proportional to presynaptic activity multiplied by the offset of the postsynaptic membrane potential from a baseline potential. This ...

Optimal Neural Spike Classification

A good such candidate is the set of the samples of the spike (or possibly also just part of the samples) ...
