The decomposition-based outer approximation algorithm for convex mixed-integer nonlinear programming.
Muts, Pavlo; Nowak, Ivo; Hendrix, Eligius María Theodorus (Springer Nature, 2020)
This paper presents a new two-phase method for solving convex mixed-integer nonlinear programming (MINLP) problems, called Decomposition-based Outer Approximation Algo- rithm (DECOA). In the first phase, a sequence of ... -
Three is not a crowd: ACPU-GPU-FPGA K-means implementation
(2017-06-15)Clustering is the task of assigning a set of objects into groups (clusters) so that objects in the same group are more similar to each other than to those in other groups. In particular, K-means is a clustering algorithm ... -
Time series analysis acceleration with advanced vectorization extensions
Quislant-del-Barrio, Ricardo; Fernández-Vega, Iván; Gutiérrez-Carrasco, Eladio Damián; Plata-González, Óscar Guillermo (Springer, 2023)

Time Series Heterogeneous Co-execution on CPU+GPU
Romero, José Carlos; González-Navarro, María Ángeles; Rodríguez-Moreno, Andrés; Asenjo-Plaza, Rafael; Cole, Murray (2019-07-10)
Time series motif (similarities) and discords discovery is one of the most important and challenging problems nowadays for time series analytics. We use an algorithm called “scrimp” that excels in collecting the relevant ... -
TMbarrier: speculative barriers using hardware transactional memory
Pedrero-Luque, Manuel; Gutiérrez-Carrasco, Eladio Damián; Plata-González, Óscar Guillermo (2018-11-15)
Barrier is a very common synchronization method used in parallel programming. Barriers are used typically to enforce a partial thread execution order, since there may be dependences between code sections before and after ... -
Towards a Software Transactional Memory for heterogeneous CPU-GPU processors
Villegas Fernández, Alejandro; González-Navarro, María Ángeles; Asenjo-Plaza, Rafael; Plata-González, Óscar Guillermo (2017-09-15)
The heterogeneous Accelerated Processing Units (APUs) integrate a multi-core CPU and a GPU within the same chip. Modern APUs provide the programmer with platform atomics, used to communicate the CPU cores with the GPU using ... -
Towards energy efficiency and productivity for decision making in mobile robot navigation
(UMA Editorial, 2022-11)Our goal in this work is to make it easy and feasible to implement solutions for autonomous decision-making and planning under uncertainty on low-power mobile platforms. We focus on practical applications, such as autonomous ... -
Towards the intelligent diagnosis of hematological diseases
Díaz-del-Pino, Sergio; Trelles-Martínez, Roberto; Perez-Wohlfeil, Esteban; Trelles-Salazar, Oswaldo Rogelio (2019-11-18)
In traditional medicine, patient diagnosis usually implies an in depth study of its state and symptoms that a specialist has to carry out. The adaptation and customization of the medical treatment to those individual ... -
Transactional memory on heterogeneous architectures
(UMA Editorial, 2018-02)Si observamos las necesidades computacionales de hoy, y tratamos de predecir las necesidades del mañana, podemos concluir que el procesamiento heterogéneo estará presente en muchos dispositivos y aplicaciones. El motivo ... -
TraTSA: A Transprecision Framework for Efficient Time Series Analysis
Fernández-Vega, Iván; Quislant-del-Barrio, Ricardo; González-Navarro, Sonia; Gutiérrez-Carrasco, Eladio Damián; Plata-González, Óscar Guillermo (Elsevier, 2022-09)
