Identifying Student Profiles Within Online Judge Systems Using Explainable Artificial Intelligence
Juan Ramón Rico-Juan, Víctor M. Sánchez-Cartagena, Jose J. Valero-Mas +1
Online Judge (OJ) systems are typically considered within programming-related courses as they yield fast and objective assessments of the code developed by the students. Such an ev…
Multilabel Prototype Generation for Data Reduction in k-Nearest Neighbour classification
Jose J. Valero-Mas, Antonio Javier Gallego, Pablo Alonso-Jiménez +1
Prototype Generation (PG) methods are typically considered for improving the efficiency of the -Nearest Neighbour (NN) classifier when tackling high-size corpora. Such approa…
Efficient Gesture Recognition for the Assistance of Visually Impaired People using Multi-Head Neural Networks
Samer Alashhab, Antonio Javier Gallego, Miguel Ángel Lozano
This paper proposes an interactive system for mobile devices controlled by hand gestures aimed at helping people with visual impairments. This system allows the user to interact wi…
Multi-Label Logo Recognition and Retrieval based on Weighted Fusion of Neural Features
Marisa Bernabeu, Antonio Javier Gallego, Antonio Pertusa
Classifying logo images is a challenging task as they contain elements such as text or shapes that can represent anything from known objects to abstract shapes. While the current s…
Two Heads are Better than One: Geometric-Latent Attention for Point Cloud Classification and Segmentation
Hanz Cuevas-Velasquez, Antonio Javier Gallego, Robert B. Fisher
We present an innovative two-headed attention layer that combines geometric and latent features to segment a 3D scene into semantically meaningful subsets. Each head combines local…
Unsupervised Neural Domain Adaptation for Document Image Binarization
Francisco J. Castellanos, Antonio-Javier Gallego, Jorge Calvo-Zaragoza
Binarization is a well-known image processing task, whose objective is to separate the foreground of an image from the background. One of the many tasks for which it is useful is t…
Incremental Unsupervised Domain-Adversarial Training of Neural Networks
Antonio-Javier Gallego, Jorge Calvo-Zaragoza, Robert B. Fisher
In the context of supervised statistical learning, it is typically assumed that the training set comes from the same distribution that draws the test samples. When this is not the…
A selectional auto-encoder approach for document image binarization
Jorge Calvo-Zaragoza, Antonio-Javier Gallego
Binarization plays a key role in the automatic information retrieval from document images. This process is usually performed in the first stages of documents analysis systems, and…
MirBot: A collaborative object recognition system for smartphones using convolutional neural networks
Antonio Pertusa, Antonio-Javier Gallego, Marisa Bernabeu
MirBot is a collaborative application for smartphones that allows users to perform object recognition. This app can be used to take a photograph of an object, select the region of…
