Abstract(in English) | We treat a problem to estimate a relation among true values from noisy data, and correct the data using the estimated relation. It is also regarded as a learning problem for the case that both inputs and outputs of examples are noisy (errors-in-variables model). The equivalence between the maximum likelihood estimate for this problem and the autoassociative learning of the sandglass network is pointed out. The sandglass network can treat multi-valued functions. However, it is able to express only surfaces (manifolds) which are homeomorphic to the plane (hyperplane). Thus the learning of closed surfaces like the sphere is hard for it. We multiply the sandglass network and construct the mixture-of-experts type network, which is able to express a broad class of multi-valued functions. |
