2019 · Applied Sciences

In this paper we perform a comparative analysis of three models for a feature representation of text documents in the context of document classification. In particular, we consider the most often used family of bag-of-words …

Combinatorial search for selecting the structure of models of dynamical systems with equation discovery

2019 · Engineering Applications of Artificial Intelligence

Automated modeling aims at the induction of mathematical models, both their structure and parameter values, from time-series measurements of observed system variables. In this paper, we address the task of model structure selection, i.e., selecting …
