Debunking the speed-fidelity trade-off: Speeding-up large-scale energy models while keeping fidelity
(2025-07-01)Energy system models are essential for planning and supporting the energy transition. However, increasing temporal, spatial, and sectoral resolutions have led to large-scale linear programming (LP) models that are often ... -
Boosting Deep Reinforcement Learning with Semantic Knowledge for Robotic Manipulators
(2025-07-01)Deep Reinforcement Learning (DRL) is a powerful framework for solving complex sequential decision-making problems, particularly in robotic control. However, its practical deployment is often hindered by the substantial ... -
Enhancing keyphrase extraction from long scientific documents using graph embeddings
(2025-07-01)This study explores the integration of graph neural network (GNN) representations with pre-trained language models (PLMs) to enhance keyphrase extraction (KPE) from lengthy documents. We demonstrate that incorporating graph ... -
Support mechanisms for low-carbon hydrogen: The risks of segmenting a commodity market
(2025-07-01)Although the actual scope of the hydrogen sector is subject to great uncertainty, a global wave of support mechanisms for low-carbon hydrogen is being registered. In many cases, these schemes aim to bridge the gap between ... -
A Stochastic Adaptive Robust Optimization Approach to Build Day-Ahead Bidding Curves for an EV Aggregator
(2025-07-08)This paper proposes a stochastic adaptive robust optimization approach to build the bidding curves of an aggregator managing a fleet of electric vehicles (EVs) participating in the day-ahead and intraday electricity markets. ... -
Alpha entropy search for new information-based Bayesian optimization
(2025-07-08)Bayesian optimization (BO) methods based on information theory have obtained state-of-the-art results in several tasks. These techniques rely on the Kullback–Leibler (KL) divergence to compute the acquisition function. We ... -
COMISET: Dataset for the analysis of malicious events in Windows systems
(2025-08-01)The evaluation of threat detection and prevention systems requires the use of datasets that are up-to-date and correctly designed according to the most common threats. Currently, the availability of event datasets containing ... -
Metric tools for sensitivity analysis with applications to neural networks
(2025-08-01)As Machine Learning models are considered for autonomous decisions with significant social impact, the need to understand how these models work rises rapidly. Explainable Artificial Intelligence (XAI) aims to provide ... -
Single-level flexible robust optimal bidding of Renewable-Only Virtual Power Plant in energy and secondary reserve markets
(2025-08-01)This paper proposes a novel single-level robust mathematical approach to model the Renewable-only Virtual Power Plant (RVPP) bidding problem in the simultaneous day-ahead and secondary reserve markets. In existing single-level ... -
Regional rebound effects of energy efficiency improvements in a spatial general equilibrium framework
(2025-08-01)We study the impact of energy efficiency improvements and associated rebound effects on regional economies in the European Union. We use a spatial dynamic computable general equilibrium model calibrated for 235 regions and ... -
From crypto to NFTs: Identifying the new wave of digital investors
(2025-08-01)The objective of this paper is to explore whether NFT investors represent a distinct cohort within the broader crypto investment sphere. Employing data from a public survey with global outreach, we first find that NFT ... -
Frequency stability services to compensate for low inertia in renewable-dominated power systems
(2025-08-01)The shift towards non-synchronous generation reduces system inertia, creating operational challenges in power systems worldwide. This inertia challenge depends on the synchronous grid size, generation mix, and the existing ... -
Floating exchange rate efficiency: Grouping patterns and pandemic impacts
(2025-08-01)This study investigates the efficiency of global floating exchange rates spanning 19 years from 2004 to 2022. We examine the presence of long memory in a sample of twenty-five floating exchange rates against the US Dollar, ... -
Life cycle assessment of clinker and cement production in Spain. Environmental assessment of decarbonisation measures
