Image Colour Segmentation by Genetic Algorithms
Vitorino Ramos, Fernando Muge
Segmentation of a colour image composed of different kinds of texture regions can be a hard problem, namely to compute for an exact texture fields and a decision of the optimum num…
Artificial Ant Colonies in Digital Image Habitats - A Mass Behaviour Effect Study on Pattern Recognition
Vitorino Ramos, Filipe Almeida
Some recent studies have pointed that, the self-organization of neurons into brain-like structures, and the self-organization of ants into a swarm are similar in many respects. If…
Map Segmentation by Colour Cube Genetic K-Mean Clustering
Vitorino Ramos, Fernando Muge
Segmentation of a colour image composed of different kinds of texture regions can be a hard problem, namely to compute for an exact texture fields and a decision of the optimum num…
Line and Word Matching in Old Documents
A. Marcolino, Vitorino Ramos, Mario Ramalho +1
This paper is concerned with the problem of establishing an index based on word matching. It is assumed that the book was digitised as better as possible and some pre-processing te…
Artificial Neoteny in Evolutionary Image Segmentation
Vitorino Ramos
Neoteny, also spelled Paedomorphosis, can be defined in biological terms as the retention by an organism of juvenile or even larval traits into later life. In some species, all mor…
The Biological Concept of Neoteny in Evolutionary Colour Image Segmentation - Simple Experiments in Simple Non-Memetic Genetic Algorithms
Vitorino Ramos
Neoteny, also spelled Paedomorphosis, can be defined in biological terms as the retention by an organism of juvenile or even larval traits into later life. In some species, all mor…
The MC2 Project [Machines of Collective Conscience]: A possible walk, up to Life-like Complexity and Behaviour, from bottom, basic and simple bio-inspired heuristics - a walk, up into the morphogenesis of information
Vitorino Ramos
Synergy (from the Greek word synergos), broadly defined, refers to combined or co-operative effects produced by two or more elements (parts or individuals). The definition is often…
On the Implicit and on the Artificial - Morphogenesis and Emergent Aesthetics in Autonomous Collective Systems
Vitorino Ramos
Imagine a "machine" where there is no pre-commitment to any particular representational scheme: the desired behaviour is distributed and roughly specified simultaneously among many…
Clustering Techniques for Marbles Classification
J. R. Caldas-Pinto, Pedro Pina, Vitorino Ramos +1
Automatic marbles classification based on their visual appearance is an important industrial issue. However, there is no definitive solution to the problem mainly due to the presen…
Self-Organized Stigmergic Document Maps: Environment as a Mechanism for Context Learning
Vitorino Ramos, Juan J. Merelo
Social insect societies and more specifically ant colonies, are distributed systems that, in spite of the simplicity of their individuals, present a highly structured social organi…
Swarms on Continuous Data
Vitorino Ramos, Ajith Abraham
While being it extremely important, many Exploratory Data Analysis (EDA) systems have the inhability to perform classification and visualization in a continuous basis or to self-or…
Web Usage Mining Using Artificial Ant Colony Clustering and Genetic Programming
Ajith Abraham, Vitorino Ramos
The rapid e-commerce growth has made both business community and customers face a new situation. Due to intense competition on one hand and the customer's option to choose from sev…
Less is More - Genetic Optimisation of Nearest Neighbour Classifiers
Vitorino Ramos, Fernando Muge
The present paper deals with optimisation of Nearest Neighbour rule Classifiers via Genetic Algorithms. The methodology consists on implement a Genetic Algorithm capable of search…
Swarming around Shellfish Larvae
Vitorino Ramos, Jonathan Campbell, John Slater +3
The collection of wild larvae seed as a source of raw material is a major sub industry of shellfish aquaculture. To predict when, where and in what quantities wild seed will be ava…
From Feature Extraction to Classification: A multidisciplinary Approach applied to Portuguese Granites
Vitorino Ramos, Pedro Pina, Fernando Muge
The purpose of this paper is to present a complete methodology based on a multidisciplinary approach, that goes from the extraction of features till the classification of a set of…
Intrusion Detection Systems Using Adaptive Regression Splines
Srinivas Mukkamala, Andrew H. Sung, Ajith Abraham +1
Past few years have witnessed a growing recognition of intelligent techniques for the construction of efficient and reliable intrusion detection systems. Due to increasing incident…
Evolving a Stigmergic Self-Organized Data-Mining
Vitorino Ramos, Ajith Abraham
Self-organizing complex systems typically are comprised of a large number of frequently similar components or events. Through their process, a pattern at the global-level of a syst…
