Tree structured data are a flexible tool to properly express many forms of hierarchical information. However, learning of such data through deep recursive models is particularly demanding. We will show through the introduction of the Deep Tree Echo State Network model (DeepTESN) that the randomized Neural Networks framework offers a formidable approach to allow an efficient treatment of learning in tree structured domains by deep architectures. Theoretical properties, for the Reservoir Computing setup constraints, and empirical behavior of the proposed approach are analyzed, showing its feasibility and accuracy.

Abstract
Tree structured data are a flexible tool to properly express many forms of hierarchical information. However, learning of such data through deep recursive models is particularly demanding. We will show through the introduction of the Deep Tree Echo State Network model (DeepTESN) that the randomized Neural Networks framework offers a formidable approach to allow an efficient treatment of learning in tree structured domains by deep architectures. Theoretical properties, for the Reservoir Computing setup constraints, and empirical behavior of the proposed approach are analyzed, showing its feasibility and accuracy.File | Dimensione | Formato | |
