El análisis de series temporales es una técnica clave para extraer y predecir sucesos en ámbitos tan diversos como la epidemiología, la genómica, la neurociencia, las ciencias medioambientales o la economía, entre otros. ... -
New formats for computing with real-numbers under round-to-nearest
Hormigo-Aguilar, Javier; Villalba-Moreno, Julio (2015-09-17)
In this paper, a new family of formats to deal with real number for applications requiring round to nearest is proposed. They are based on shifting the set of exactly represented numbers which are used in conventional ... -
New Results on Non-normalized Floating-point Formats
González-Navarro, Sonia; Hormigo-Aguilar, Javier (IEEE Computer Society, 2019)
Compulsory normalization of the represented numbers is a key requirement of the floating-point standard. This requirement contributes to fundamental characteristics of the standard, such as taking the most of the precision ... -
Normalizing or not normalizing? An open question for floating-point arithmetic in embedded systems
González-Navarro, Sonia; Hormigo-Aguilar, Javier (IEEE, 2017-07-24)
Emerging embedded applications lack of a specific standard when they require floating-point arithmetic. In this situation they use the IEEE-754 standard or ad hoc variations of it. However, this standard was not designed ... -
Novel parallel approaches to efficiently solve spatial problems on heterogeneous CPU-GPU systems
(UMA Editorial, 2022)In recent years, approaches that seek to extract valuable information from large datasets have become particularly relevant in today's society. In this category, we can highlight those problems that comprise data analysis ... -
On an OptLearn implementation using collaborative filtering.
Fuster López, Alejandro; Guerrero-García, Pablo; Hendrix, Eligius María Theodorus; Martínez-Cruz, Jesús; Nowak, Ivo (2023)
The aim of the iMath project is to develop a recommender system where a student is recommended a next question or literature in a learning platform MathE. This paper describes the systems developed based on collaborative ... -
On computational procedures for Value Iteration in inventory control
Dynamic programming (DP) is often seen in inventory control to lead to optimal ordering policies. When considering stationary demand, Value Iteration (VI) may be used to derive the best policy. In this paper, our focus is ... -
On conceptualisation and an overview of learning path recommender systems in e-learning.
Fuster López, Alejandro; Martínez-Cruz, Jesús; Guerrero-García, Pablo; Hendrix, Eligius María Theodorus; Košir, Andrej; Nowak, Ivo; Oneto, Luca; Sirmakessis, Spiros; Pacheco, Maria Fátima; Fernandes, Florbela Pires; Pereira, Ana Isabel[et al.] (2024-06-10)
The use of e-learning systems has a long tradition, where students can study online helped by a system. In this context, the use of recommender systems is relatively new. In our research project, we investigated various ... -
On Dealing with Minima at the Border of a Simplicial Feasible Area in Simplicial Branch and Bound.
G.-Tóth, Boglárka; Hendrix, Eligius María Theodorus; Casado, Leocadio G.; Messine, Fréderic (Springer Nature, 2024-07-22)
We consider a simplicial branch and bound Global Optimization algorithm, where the search region is a simplex. Apart from using longest edge bisection, a simplicial partition set can be reduced due to monotonicity of the ... -
On decomposition and multiobjective-based column and disjunctive cut generation for MINLP.
Muts, Pavlo; Nowak, Ivo; Hendrix, Eligius María Theodorus (Springer Nature, 2020)
Most industrial optimization problems are sparse and can be formulated as block- separable mixed-integer nonlinear programming (MINLP) problems, defined by linking low-dimensional sub-problems by (linear) coupling constraints. ... -
On how to improve tracklet-based gait recognition systems
Marín-Jiménez, Manuel J.; Castro Payán, Francisco Manuel; Carmona-Poyato, Ángel; Guil-Mata, Nicolás (Elsevier, 2015-12-15)
Abstract Recently, short-term dense trajectories features (DTF) have shown state-of-the-art results in video recognition and retrieval. However, their use has not been extensively studied on the problem of gait recognition. ... -
On Optimizing Ensemble Models using Column Generation.
Aziz, Vanya; Wu, Ouyang; Nowak, Ivo; Hendrix, Eligius María Theodorus; Kronqvist, Jan (Springer Nature, 2024-02-22)
In recent years, an interest appeared in integrating various optimization algorithms in machine learning. We study the potential of ensemble learning in classification tasks and how to efficiently decompose the underlying ... -
On Order Policies for a Perishable Product in Retail.
Hendrix, Eligius María Theodorus; Pauls-Worm, Karin G.J.; De Jong, Maartje V. (Vilnius University Press, 2023-05)
We study an inventory control problem of a perishable product with a fixed short shelf life in Dutch retail practice. The demand is non-stationary during the week but stationary over the weeks, with mixed LIFO and FIFO ... -
On order policies with pre-specified order schedules for a perishable product in retail.
This paper studies a retail inventory system for a perishable product, based on a practical setting in Dutch retail. The product has a fixed shelf life of three days upon delivery at the store and product demand has a ... -
