Octahedral Transforms for 3D Image Processing
Institute of Electrical and Electronics Engineers (2009)The octahedral group is one of the finite subgroups of the rotation group in three-dimensional Euclidean space and a symmetry group of the cubic grid. Compression and filtering of three-dimensional volumes are given as ... -
Off-Line Evaluation of Mobile-Centric Indoor Positioning Systems: The Experiences from the 2017 IPIN Competition
MDPI (2018)The development of indoor positioning solutions using smartphones is a growing activity with an enormous potential for everyday life and professional applications. The research activities on this topic concentrate on the ... -
On compiler error messages: what they say and what they mean
Hindawi Publishing Corporation (2010)Programmers often encounter cryptic compiler error messages that are difficult to understand and thus difficult to resolve. Unfortunately, most related disciplines, including compiler technology, have not paid much attention ... -
On Metrics for Location-Aware Games
MDPI (2017-09)Metrics are important and well-known tools to measure users’ behavior in games, and gameplay in general. Particularities of location-aware games—a class of games where the player’s location plays a central role-demand ... -
On the Complementarity of Face Parts for Gender Recognition
Springer Verlag (2008)This paper evaluates the expected complementarity between the most prominent parts of the face for the gender recognition task. Given the image of a face, five important parts (right and left eyes, nose, mouth and chin) ... -
On the influence of spatial information for hyper-spectral satellite imaging characterization
Springer (2011)Land-use classification for hyper-spectral satellite images requires a previous step of pixel characterization. In the easiest case, each pixel is characterized by its spectral curve. The improvementof the spectral and ... -
On the interconnection of message passing systems
Elsevier (2008)One of the most important abstractions for designing distributed programs is the broadcast facility. In this paper, we study the interconnection of distributed message passing systems. We have shown that totally ordered ... -
On the Problem of Automatically Aligning Indicators to SDGs
Springer Nature (2023-10-21)In this paper we present a first approach to the application of transformer-based language models to the automatic alignment to sustainable development goals (SDGs). This task is quite relevant for the development of new ... -
On the suitability of combining feature selection and resampling to manage data complexity
Springer Verlag (2010)The effectiveness of a learning task depends on data com- plexity (class overlap, class imbalance, irrelevant features, etc.). When more than one complexity factor appears, two or more preprocessing techniques should be ... -
On the suitability of resampling techniques for the class imbalance problem in credit scoring
Palgrave Macmillan (2013)In real-life credit scoring applications, the case in which the class of defaulters is under-represented in comparison with the class of non-defaulters is a very common situation, but it has still received little attention. ... -
On-line classification of data streams with missing values based on reinforcement learning
Springer (2011)In some applications, data arrive sequentially and they are not available in batch form, what makes difficult the use of traditional classification systems. In addition, some attributes may lack due to some real-world ... -
On-line learning from streaming data with delayed attributes: A comparison of classifiers and strategies
Springer (2011-10)In many real applications, data are not all available at the same time, or it is not affordable to process them all in a batch process, but rather, instances arrive sequentially in a stream. The scenario of streaming data ... -
One-Sided Prototype Selection on Class Imbalanced Dissimilarity Matrices
Springer Berlin Heidelberg (2012)In the dissimilarity representation paradigm, several prototype selection methods have been used to cope with the topic of how to select a small representation set for generating a low-dimensional dissimilarity space. In ... -
Ontology integration using mappings: towards getting the right logical consequences
Springer Verlag (Germany) (2009)We propose a general method and novel algorithmic techniques to facilitate the integration of independently developed ontologies using mappings. Our method and techniques aim at helping users understand and evaluate the ... -
Ontology refinement for improved information retrieval
Elsevier (2010)Ontologies are frequently used in information retrieval being their main applications the expansion of queries, semantic indexing of documents and the organization of search results. Ontologies provide lexical items, allow ... -
Optimizing fairness in cellular networks with mobile drone relays
Elsevier (2023-02-10)Aiding the ground cellular network with aerial base stations carried by drones has experienced an intensive raise of interest in the past years. Reconfigurable air-to-ground channels enable aerial stations to enhance users’ ... -
Optimizing the management of continuous level of detail models on GPU
Elsevier (2008)In this paper we present a new continuous multiresolution framework which has been developed in view of the outstanding evolution of hardware. Our interest not only focuses on exploiting GPUs possibilities, but also on ... -
Optimizing UAV Resupply Scheduling for Heterogeneous and Persistent Aerial Service
Institute of Electrical and Electronics Engineers (2023-08)With the current advances in unmanned aerial vehicle (UAV) technologies, aerial vehicles are becoming very attractive for many purposes. However, currently the bottleneck in their adoption is no longer due to architectural ... -
