Can a powerful neural network be a teacher for a weaker neural network?

Nicola Landro, Ignazio Gallo, Riccardo La Grassa

The transfer learning technique is widely used to learning in one context and applying it to another, i.e. the capacity to apply acquired knowledge and skills to new situations. Bu…

OCmst: One-class Novelty Detection using Convolutional Neural Network and Minimum Spanning Trees

Riccardo La Grassa, Ignazio Gallo, Nicola Landro

We present a novel model called One Class Minimum Spanning Tree (OCmst) for novelty detection problem that uses a Convolutional Neural Network (CNN) as deep feature extractor and g…

A Classification Methodology based on Subspace Graphs Learning

Riccardo La Grassa, Ignazio Gallo, Alessandro Calefati +1

In this paper, we propose a design methodology for one-class classifiers using an ensemble-of-classifiers approach. The objective is to select the best structures created during th…

Binary Classification using Pairs of Minimum Spanning Trees or N-ary Trees

Riccardo La Grassa, Ignazio Gallo, Alessandro Calefati +1

One-class classifiers are trained with target class only samples. Intuitively, their conservative modelling of the class description may benefit classical classification tasks wher…
