Reframing Audience Expansion through the Lens of Probability Density Estimation
Claudio Carvalhaes
Audience expansion has become an important element of prospective marketing, helping marketers create target audiences based on a mere representative sample of their current custom…
The Surface Laplacian Technique in EEG: Theory and Methods
Claudio Carvalhaes, J. Acacio de Barros
This paper reviews the method of surface Laplacian differentiation to study EEG. We focus on topics that are helpful for a clear understanding of the underlying concepts and its ef…
Exploring non-signalling polytopes with negative probability
G. Oas, J. Acacio de Barros, C. Carvalhaes
Bipartite and tripartite EPR-Bell type systems are examined via joint quasi-probability distributions where elementary probabilities are permitted to be negative. It is shown that…
The joint use of the tangential electric field and surface Laplacian in EEG classification
C. G. Carvalhaes, J. Acacio de Barros, M. Perreau-Guimarães +1
This paper discusses the use of the scalp electric field to decode EEG-recorded brain processes. Instead of using bipolar measurements, the scalp electric field is described as a 3…
Recognition of Words from the EEG Laplacian
J. Acacio de Barros, C. G. Carvalhaes, J. P. R. F. de Mendonça +1
Recent works on the relationship between the electro-encephalogram (EEG) data and psychological stimuli show that EEG recordings can be used to recognize an auditory stimulus prese…
Dynamic modelling of a freshwater stream community from experimental field data
Roberto de Moraes Lima Silveira, Claudio Goncalves Carvalhaes, Claudio Sasaki +2
We developed mathematical models that simulate community dynamics derived from a series of perturbation experiments. These experiments were performed in an Atlantic Forest stream.…
