Incremental Learning of Local Linear Mappings

A new incremental network model for supervised learning is proposed. The model builds up a structure of units each of which has an associated local linear mapping (LLM). Error information obtained during training is used to determine where to insert new units whose LLMs are interpolated from their neighbors. Simulation results for several classiication tasks indicate fast convergence as well as good generalization. The ability of the model to also perform function approximation is demonstrated by an example.
