The exact scheme is a recursive one, namely the generalized distributive law (GDL), whose purpose is to distribute all operators across the conditionally independent (CI) factors of the joint model, so ...
For practical use, two novel algorithms, namely the no-longer-needed (NLN) algorithm and the generalized form of the Markovian Forward-Backward (FB) algorithm, recursively factorizes and computes the CI ...
indices can be updated by either sliding window approach (LZ77 algorithm [Ziv and Lempel (1977) ]), or a tree-structure approach (LZ78 algorithm [Ziv and Lempel (1978) ]). ...
