Emergence and Evolution of Hierarchical Structure in Complex Systems

1 code implementation13 May 2018 Payam Siyari, Bistra Dilkina, Constantine Dovrolis

It is well known that many complex systems, both in technology and nature, exhibit hierarchical modularity: smaller modules, each of them providing a certain function, are used within larger modules that perform more complex functions.

The Generalized Smallest Grammar Problem

no code implementations31 Aug 2016 Payam Siyari, Matthias Gallé

The Smallest Grammar Problem -- the problem of finding the smallest context-free grammar that generates exactly one given sequence -- has never been successfully applied to grammatical inference.

Lexis: An Optimization Framework for Discovering the Hierarchical Structure of Sequential Data

no code implementations17 Feb 2016 Payam Siyari, Bistra Dilkina, Constantine Dovrolis

We also consider the problem of identifying the set of intermediate nodes (substrings) that collectively form the "core" of a Lexis-DAG, which is important in the analysis of Lexis-DAGs.
