On the usage of generative models for network anomaly detection in multivariate time-series.
(ACM, 2020)
Despite the many attempts and approaches for anomaly detection explored over the years, the automatic detection of rare events in data communication networks remains a complex problem. In this paper we introduce Net-GAN, ...
Risk assessment of diabetes mellitus by chaotic globals to heart rate variability via six power spectra
(2017-09-01)
Background: The priniciple objective here is to analyze cardiovascular dynamics in diabetic subjects by actions related to heart rate variability (HRV). The correlation of chaotic globals is vital to evaluate the probability ...
A contribuição da informação contábil para a previsão de retornos de ações: avaliação a partir de modelos de séries temporais
(Universidade Federal de Minas GeraisUFMG, 2012-07-12)
The objective of this research was to determine if the use of financial indicators improves the capacity of the stock return forecast over forecasts made only from the returns past history. Univariate models forecasting ...
A framework for causal discovery in non-intervenable systems
(American Institute of Physics, 2021-12)
Many frameworks exist to infer cause and effect relations in complex nonlinear systems, but a complete theory is lacking. A new framework is presented that is fully nonlinear, provides a complete information theoretic ...
Estadística multivariada: inferencia y métodos

La segunda edición tiene en cuenta al lector para quien se pensó debe ir dirigido, es decir cualquier persona que posea conocimientos básicos de matemáticas y estadística. Aunque se ha mantenido la estructura de la primera ...
On the importance of examining the relationship between shape data and biologically meaningful variables. An example studying allometry with geometric morphometrics.
(Sociedad Española de Paleontología, 2013-07)
Geometric morphometrics (GM) is a tool for the statistical analysis of shape on Cartesian landmark coordinates. However, because GM studies commonly focus on the description of morphological trends within shape space (or ...
Rastreamento da máxima potência em conexão série de sistemas fotovoltaicos utilizando o controle granular
(Universidade Tecnológica Federal do ParanáCornelio ProcopioBrasilEngenharia ElétricaUTFPR, 2017-06-12)
Considering the use of energy from photovoltaic (PV) systems, this work presents a comparative study of the traditional PV system with the multi-string PV system. The traditional system consists of three PV panels associated ...
