Estimating crowd density with Minkowski fractal dimension
(ICASSP, IEEE International Conference on Acoustics, Speech and Signal Processing - Proceedings, 1999-01-01) [Trabalho apresentado em evento]
The estimation of the number of people in an area under surveillance is very important for the problem of crowd monitoring. When an area reaches an occupation level greater than the projected one, people's safety can be ...
Feedforward neural networks based on PPS-wavelet activation functions
(Ii Workshop on Cybernetic Vision, Proceedings, 1997-01-01) [Trabalho apresentado em evento]
Function approximation is a very important task in environments where computation has to be based on extracting information from data samples in real world processes. Neural networks and wavenets have been recently seen ...
Function approximation by polynomial wavelets generated from powers of sigmoids
(Wavelet Applications Iii, 1996-01-01) [Trabalho apresentado em evento]
Comparative study between RBF and radial-PPS neural networks
(Applications and Science of Computational Intelligence, 1998-01-01) [Trabalho apresentado em evento]
The study of function approximation is motivated by the human limitation and inability to register and manipulate with exact precision the behavior variations of the physical nature of a phenomenon. These variations are ...
A simple mechanism to deal with sequential code in dataflow architectures
(Fifth International Conference on High Performance Computing, Proceedings, 1998-01-01) [Trabalho apresentado em evento]
The aim of this work is to propose a simple and efficient mechanism to deal with the problem of executing sequential code in a pure dataflow machine. Our results is obtained with a simulator of Wolf  architecture. The ...

The main purpose of this paper is to investigate theoretically and experimentally the use of family of Polynomial Powers of the Sigmoid (PPS) Function Networks applied in speech signal representation and function approximation. ...
Simulation and analysis of a collisionless optical interconnection network
(Its '98 Proceedings - Sbt/ieee International Telecommunications Symposium, Vols 1 and 2, 1998-01-01) [Trabalho apresentado em evento]
This article describes the simulation and analysis of collisionless optical interconnection network, which the objective is to achieve a high performance level based on a single protocol control. The optical coupler has ...
Mathematical tests about the existence and applications of PPS-wavelets in function approximation problems
(Wavelet Applications V, 1998-01-01) [Trabalho apresentado em evento]
Neural networks and wavelet transform have been recently seen as attractive tools for developing eficient solutions for many real world problems in function approximation. Function approximation is a very important task ...
