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 ...

Parallel Interconnection of Broadcast Systems with Multiple FIFO Channels
Springer Berlin Heidelberg (2009)This paper proposes new protocols for the interconnection of FIFO- and causal-ordered broadcast systems, thus increasing their scalability. They use several interconnection links between systems, which avoids bottleneck ...
-
Partially-coherent spirally-polarized gradual-edge imaging
Elsevier (2019)In this work we develop a partially-coherent spirally-polarized imaging system for generating gradual edge detection images. A rotating diffuser is used for producing illumination sources with tunable degree of coherence. Using ...
