Abstract

Sigma-Pi (Σ-驴) neural networks (SPNNs) are known to provide more powerful mapping capability than traditional feed-forward neural networks. A unified convergence analysis for the batch gradient algorithm for SPNN learning is presented, covering three classes of SPNNs: Σ-驴-Σ, Σ-Σ-驴 and Σ-驴-Σ-驴. The monotonicity of the error function in the iteration is also guaranteed.
