A Hierarchical Genetic Optimization of a Fuzzy Logic System for Flow Control in Micro Grids

no code implementations16 Apr 2016 Enrico De Santis, Antonello Rizzi, Alireza Sadeghian

In particular, this study focuses on the application of a Hierarchical Genetic Algorithm (HGA) for tuning the Rule Base (RB) of a Fuzzy Inference System (FIS), trying to discover a minimal fuzzy rules set in a Fuzzy Logic Controller (FLC) adopted to perform decision making in the microgrid.

Data-driven detrending of nonstationary fractal time series with echo state networks

1 code implementation24 Oct 2015 Enrico Maiorino, Filippo Maria Bianchi, Lorenzo Livi, Antonello Rizzi, Alireza Sadeghian

We assume that such a dynamical process is predictable to a certain degree by means of a class of recurrent networks called Echo State Network (ESN), which are capable to model a generic dynamical process.

On the impact of topological properties of smart grids in power losses optimization problems

no code implementations19 Jan 2015 Francesca Possemato, Maurizio Paschero, Lorenzo Livi, Antonello Rizzi, Alireza Sadeghian

In this paper, we face the problem of joint optimization of both topology and network parameters in a real smart grid.

An Agent-Based Algorithm exploiting Multiple Local Dissimilarities for Clusters Mining and Knowledge Discovery

no code implementations17 Sep 2014 Filippo Maria Bianchi, Enrico Maiorino, Lorenzo Livi, Antonello Rizzi, Alireza Sadeghian

We propose a multi-agent algorithm able to automatically discover relevant regularities in a given dataset, determining at the same time the set of configurations of the adopted parametric dissimilarity measure yielding compact and separated clusters.

Classifying sequences by the optimized dissimilarity space embedding approach: a case study on the solubility analysis of the E. coli proteome

no code implementations17 Aug 2014 Lorenzo Livi, Antonello Rizzi, Alireza Sadeghian

We evaluate a version of the recently-proposed classification system named Optimized Dissimilarity Space Embedding (ODSE) that operates in the input space of sequences of generic objects.

Characterization of graphs for protein structure modeling and recognition of solubility

no code implementations30 Jul 2014 Lorenzo Livi, Alessandro Giuliani, Alireza Sadeghian

This paper deals with the relations among structural, topological, and chemical properties of the E. Coli proteome from the vantage point of the solubility/aggregation propensity of proteins.

Data granulation by the principles of uncertainty

no code implementations26 Jul 2014 Lorenzo Livi, Alireza Sadeghian

The proposed framework is conceived (i) to offer a guideline for the synthesis of information granules and (ii) to build a groundwork to compare and quantitatively judge over different data granulation procedures.

Modeling and Recognition of Smart Grid Faults by a Combined Approach of Dissimilarity Learning and One-Class Classification

no code implementations25 Jul 2014 Enrico De Santis, Lorenzo Livi, Alireza Sadeghian, Antonello Rizzi

Modern electric power grids (smart grids) are equipped with smart sensors that allow to gather real-time information regarding the physical status of all the component elements belonging to the whole infrastructure (e. g., cables and related insulation, transformers, breakers and so on).
