Smoothing Problem in 2D Images with Tissue-like P Systems and Parallel Implementation
(Fénix Editora, 2011)
Smoothing is often used in Digital Imagery to reduce noise within an image. In this paper we present a Membrane Computing algorithm for smoothing 2D images in the framework of tissue-like P systems. The algorithm has ...

Computational topology on neural networks: from the data to the model
(2021)
Machine learning is drawn from a dataset that needs to be explained. Following this aim, a model is described to make predictions. These datasets can be of very different nature, as well as the problems they pose: ...

Solving SAT with Antimatter in Membrane Computing
(Fénix Editora, 2015)
The set of NP-complete problems is split into weakly and strongly NP- complete ones. The di erence consists in the in uence of the encoding scheme of the input. In the case of weakly NP-complete problems, the intractability ...

Two-hidden-layer feed-forward networks are universal approximators: A constructive approach
(ScienceDirect, 2020-11)
It is well-known that artificial neural networks are universal approximators. The classical existence result proves that, given a continuous function on a compact set embedded in an n-dimensional space, there exists a ...

Integer Linear Programming for Tissue-like P Systems
(Fénix Editora, 2011)
In this paper we report a work-in-progress whose final target is the implementation of tissue-like P system in a cluster of computers which solves some instances of the segmentation problem in 2D Digital Imagery. We focus ...

Simplicial-Map Neural Networks Robust to Adversarial Examples
(MDPI [Commercial Publisher], 2021-01-15)
Broadly speaking, an adversarial example against a classification model occurs when a small perturbation on an input data point produces a change on the output label assigned by the model. Such adversarial examples represent ...

Designing a new software tool for digital imagery based on P systems
(2012)
In this paper we present a new software tool for dealing with the problem of segmentation in Digital Imagery. The implementation is inspired in the design of a tissue-like P system which solves the problem in constant time ...

Solving the Independent Set problem by using tissue-like P systems with cell division
(Springer, 2009)
Tissue-like P systems with cell division is a computing model in the framework of Membrane Computing inspired by the intercellular communication and neuronal synaptics. It considers the cells as unit processors and the ...
