Research article On the statistical assessment of classifiers using DNA microarray data
SPARSE VS DENSE DATA REPRESENTATIONS IN KERNEL METHODS (2008)
N. Ancona, R. Maglietta, E. Stella
This paper focuses on the problem of how data representation influences the generalization error of kernel based learning machines like Support Vector Machines (SVM) for classification. Frame theory...

Abstract. This paper presents a comparative evaluation of the performance of linear and non-linear techniques for combining the outputs of an ensemble of neural network classifiers, expressed as...
Odor detection and recognition with Support Vector Machines (2008)
C. Distante, N. Ancona, P. Siciliano
Pattern recognition techniques have widely been used in the context of odor recognition. The recognition of mixtures and simple odors as separate clusters is an untractable problem with some of the...
Correcting colours for aided recomposition of fragments (2008)
G. Carlomagno, F. Renna, N. Ancona, N. Mosca, G. Attolico, A. Distante
The paper describes the colour correction approach of a system for the virtual aided recomposition of fragmented frescos, being developed and proved for the reconstruction of the S. Matthew’s...
Maglietta, R., Piepoli, A., Catalano, D., Licciulli, F., Carella, M., Liuni, S., ...
Motivation: A major challenge in current biomedical research is the identification of cellular processes deregulated in a given pathology through the analysis of gene expression profiles. To this...
On the statistical assessment of classifiers using DNA microarray data (2006)
Ancona, N, Maglietta, R, Piepoli, A, D'Addabbo, A, Cotugno, R, Savino, M, ...
Abstract Background In this paper we present a method for the statistical assessment of cancer predictors which make use of gene expression profiles. The methodology is applied to a new data set of...
Ancona, N., Maestri, R., Marinazzo, D., Nitti, L., Pellicoro, M., Pinna, G. D., ...
In this paper we show that different physiological states and pathological conditions may be characterized in terms of predictability of time series signals from the underlying biological system. In...
Ball Detection in Static Images with Support Vector Machines for Classification (2003)
N. Ancona, G. Cicirelli, E. Stella, A. Distante
We present a general method for detecting balls in images at the aim of automatically detecting goals during a soccer match. The detector learns the object to detect by using a supervised learning...
A Floor Boundary Sensor for Autonomous Robot Navigation (1991)
Bellutta And, P. Bellutta, N. Ancona
Simple indoor navigation subtasks, such as moving an autonomous platform robot in a corridor parallel to a wall or correcting its trajectory to avoid small obstacles, can be accomplished using...
