Instance selection for multi-label learning based on a scalable evolutionary algorithm
(IEEE, 2021)
Multi-label classification has recently attracted
greater research interest as a data mining task. Many current ap-
plications in data mining address problems having instances that
belong to more than one class, which ...
CRIBEL: Lifelong learning social network governed by academic institutions: an affordable serverless model in the cloud
(IATED, 2023)
Academic institutions, teachers, students and workers are facing important changes in the way they
organise work and training in new skills demanded by companies in the face of the new challenges of
society in general ...
Higher education institutions to promote a lifelong learning strategy
(IATED, 2019)
In today’s society students and graduates are demanded to be equipped with two fundamental attitudes.
The first is being active learners enrolled in all different activities related to Active Learning that have
place at ...
A novel backtracking approach for two-axis solar PV tracking plants
(Elsevier, 2020)
Solar tracking is a technique required to increase energy production in multiple photovoltaic (PV) facilities. In these plants, during low-elevation solar angle hours, shadows appear between the collectors causing a dramatic ...
An Extended Approach of a Two-Stage Evolutionary Algorithm in Artificial Neural Networks for Multiclassification Tasks
(Springer, 2016)
This chapter considers a recent algorithm to add broader diversity at the beginning of the evolutionary process and extends it to sigmoidal neural networks. A simultaneous evolution of architectures and weights is performed ...
A two-stage algorithm in evolutionary product unit neural networks for classification
(Elsevier, 2011)
This paper presents a procedure to add broader diversity at the beginning of the evolutionary process. It consists of creating two initial populations with different parameter settings, evolving them for a small number of ...
Improvement of small wind turbine control in the transition region
(MDPI, 2020)
Wind energy conversion systems are very challenging from the control system viewpoint. The control difficulties are even more challenging when wind turbines are able to operate at variable speed and variable pitch. The ...
Reflection-aware generation and identification of square marker dictionaries
(MDPI, 2022)
Square markers are a widespread tool to find correspondences for camera localization because of their robustness, accuracy, and detection speed. Their identification is usually based on a binary encoding that accounts for ...
Unsupervised generation of polygonal approximations based on the convex hull
(Elsevier, 2020)
The present paper proposes a new non-optimal but unsupervised algorithm, called ICT-RDP, for generation of polygonal approximations based on the convex hull. Firstly, the new algorithm takes into account the convex hull ...
Multifractal detrended fluctuation analysis of sheep livestock prices in origin
(Elsevier, 2013)
The multifractal detrended fluctuation analysis (MF-DFA) is used to verify whether or not the returns of time series of prices paid to farmers in original markets can be described by the multifractal approach. By way of ...
