Information processing system, network structure learning device, link strength prediction device, link strength prediction method, and program

摘要

An information processing system separately generates sample sequences from a posterior distribution of each random variable in a probability model representing the structure of a template network that serves as a template for a plurality of networks whose network structures are to be learned, and from a posterior distribution of each random variable in a probability model representing the structures of the plurality of networks, using learning data and hyperparameters relating to the plurality of networks. Next, the information processing system derives a predictive value of the strength of a link specified by an external variable based on the external variable and on the sample sequences.
