Supervised non-parametric discretization based on Kernel density estimation
(Pattern Recognition Letters, 2019-12-19)
Nowadays, machine learning algorithms can be found in many applications where the classifiers play a key role. In this context, discretizing continuous attributes is a common step previous to classification tasks, the main ...
Soft information for localization-of-things
(Proceeding of the IEEE, 2019-11-01)
Location awareness is vital for emerging Internetof-
Things applications and opens a new era for Localizationof-
Things. This paper first reviews the classical localization
techniques based on single-value metrics, such ...
An evolutionary discretized Lambert approach for optimal long-range rendezvous considering impulse limit
(Aerospace Science and Technology, 2019-09-18)
In this paper, an approach is presented for finding the optimal long-range space rendezvous in terms of fuel and time, considering limited impulse. In this approach , the Lambert problem is expanded towards a discretized ...
Analyzing rare event, anomaly, novelty and outlier detection terms under the supervised classification framework
(Artificial Intelligence Review, 2019-09-01)
In recent years, a variety of research areas have contributed to a set of related problems with rare event, anomaly, novelty and outlier detection terms as the main actors. These multiple research areas have created a ...
Crowd-Centric Counting via Unsupervised Learning
(2019 IEEE International Conference on Communications Workshops (ICC Workshops), 2019-07-11)
Counting targets (people or things) within a moni-tored area is an important task in emerging wireless applications,including those for smart environments, safety, and security.Conventional device-free radio-based ...
A mathematical analysis of edas with distance-based exponential models
(GECCO '19 Proceedings of the Genetic and Evolutionary Computation Conference Companion, 2019-07-01)

Optimal multi-impulse space rendezvous considering limited impulse using a discretized Lambert problem combined with evolutionary algorithms
(8th European Conference for Aeronautics and Space Sciences, 2019-07-01)
In this paper, a direct approach is presented to tackle the multi-impulse rendezvous problem considering the impulse limit. Particularly, the standard Lambert problem is extended toward several consequential orbit transfers ...
Approaching the Quadratic Assignment Problem with Kernels of Mallows Models under the Hamming Distance
(Proceedings of the Genetic and Evolutionary Computation Conference Companion, 2019-07)
The Quadratic Assignment Problem (QAP) is a specially challenging permutation-based np-hard combinatorial optimization problem, since instances of size $n>40$ are seldom solved using exact methods. In this sense, many ...
K-means for massive data
(2019-04-30)
The $K$-means algorithm is undoubtedly one of the most popular clustering analysis techniques, due to its easiness in the implementation, straightforward parallelizability
and competitive computational complexity, when ...
Early classification of time series using multi-objective optimization techniques
(Information Sciences, 2019-04-23)
In early classification of time series the objective is to build models which are able to make class-predictions for time series as accurately and as early as possible, when only a part of the series is available. It is ...
