Arithmetic is expensive. If one has fewer bits to add and multiply once can do so faster and cheaper. Hence interest in lo-bit neural nets. Zhou et al. have an approach that they test on image recognition that shows one can get away with fewer bits of resolution, for example Read more…
The image below shows correlations between viewing of TV networks at increasing time lags. The central ridge reappears at a lag of a week showing recurrent weekly behaviour. With longer records this would be a natural target for empirical dynamical modelling a la Sugihara, as previously outlined in the post Read more…
A dynamical system is one that evolves with time either stochastically or deterministically. The evolution is described by a set of differential equations. The instantaneous state of a dynamical system is represented as a point in some phase space. As the system evolves the point moves describing a trajectory in Read more…
