A federated data-driven evolutionary algorithm

چکیده

Data-driven evolutionary optimization has witnessed great success in solving complex real-world problems. However, existing data-driven algorithms require that all data are centrally stored, which is not always practical and may be vulnerable to privacy leakage security threats if the must collected from different devices. To address above issue, this paper proposes a federated framework able perform driven when distributed on multiple On basis of learning, sorted model aggregation method developed for aggregating local surrogates based radial-basis-function networks. In addition, surrogate management strategy suggested by designing an acquisition function takes into account information both global models. Empirical studies set widely used benchmark functions presence various distributions demonstrate effectiveness proposed framework.

A quantum evolutionary algorithm for data clustering

The emerging field of quantum computing has recently created much interest in the computer science community due to the new concepts it suggests to store and process data. In this paper, we explore some of these concepts to cope with the data clustering problem. Data clustering is a key task for most fields like data mining and pattern recognition. It aims to discover cohesive groups in large d...

A Data-Driven Evolutionary Algorithm for Mapping Multibasin Protein Energy Landscapes

Evidence is emerging that many proteins involved in proteinopathies are dynamic molecules switching between stable and semistable structures to modulate their function. A detailed understanding of the relationship between structure and function in such molecules demands a comprehensive characterization of their conformation space. Currently, only stochastic optimization methods are capable of e...

Enhancing Learning from Imbalanced Classes via Data Preprocessing: A Data-Driven Application in Metabolomics Data Mining

This paper presents a data mining application in metabolomics. It aims at building an enhanced machine learning classifier that can be used for diagnosing cachexia syndrome and identifying its involved biomarkers. To achieve this goal, a data-driven analysis is carried out using a public dataset consisting of 1H-NMR metabolite profile. This dataset suffers from the problem of imbalanced classes...

An Evolutionary Data Clustering Algorithm

Data mining is the process of deriving knowledge from data. The data clustering is a classical activity in data mining. Clustering is the process of grouping objects together in such a way that the objects belonging to the same group are similar and those belonging to different groups are dissimilar. In this paper we propose a method to carry out data clustering using Evolutionary Computation. ...
