Minimax Classification under Concept Drift with Multidimensional Adaptation and Performance Guarantees 

Alvarez, V.Autoridad BCAM; Mazuelas, S.Autoridad BCAM; Lozano, J.A.Autoridad BCAM (2022-07)
The statistical characteristics of instance-label pairs often change with time in practical scenarios of supervised classification. Conventional learning techniques adapt to such concept drift accounting for a scalar rate ...

The role of asymmetric prediction losses in smart charging of electric vehicles 

Straka, M.; Buzna, L.; Refa, N.; Mazuelas, S.Autoridad BCAM (2022-07-01)
Climate change prompts humanity to look for decarbonisation opportunities, and a viable option is to supply electric vehicles with renewable energy. The stochastic nature of charging demand and renewable generation requires ...

Variational Bayesian Framework for Advanced Image Generation with Domain-Related Variables 

li, Y.; Mazuelas, S.Autoridad BCAM; Shen, Y. (2022-05-23)
Deep generative models (DGMs) and their conditional counterparts provide a powerful ability for general-purpose generative modeling of data distributions. However, it remains challenging for existing methods to address ...

Generalized Maximum Entropy for Supervised Classification 

Mazuelas, S.Autoridad BCAM; Shen, Y.; Pérez, A.Autoridad BCAM (2022-04)
The maximum entropy principle advocates to evaluate events’ probabilities using a distribution that maximizes entropy among those that satisfy certain expectations’ constraints. Such principle can be generalized for ...

A Deep Learning Approach for Generating Soft Range Information from RF Data 

li, Y.; Mazuelas, S.Autoridad BCAM; Shen, Y. (2022-01-24)
Radio frequency (RF)-based techniques are widely adopted for indoor localization despite the challenges in extracting sufficient information from measurements. Soft range information (SRI) offers a promising alternative ...

Derivation of a Cost-Sensitive COVID-19 Mortality Risk Indicator Using a Multistart Framework 

Armañanzas, R.Autoridad BCAM; Diaz, A.Autoridad BCAM; Martinez, M.; Mazuelas, S.Autoridad BCAM (2022-01-14)
The overall global death rate for COVID-19 patients has escalated to 2.13% after more than a year of worldwide spread. Despite strong research on the infection pathogenesis, the molecular mechanisms involved in a fatal ...

A Semi-Supervised Learning Approach for Ranging Error Mitigation Based on UWB Waveform 

Li, Y.; Mazuelas, S.Autoridad BCAM; Shen, Y. (2021-12-30)
Localization systems based on ultra-wide band (UWB) measurements can have unsatisfactory performance in harsh environments due to the presence of non-line-of-sight (NLOS) errors. Learning-based methods for error ...

Deep GEM-based network for weakly supervised UWB ranging error mitigation 

Li, Y; Mazuelas, S.Autoridad BCAM; Shen, Y. (2021-12-30)
Ultra-wideband (UWB)-based techniques, while becoming mainstream approaches for high-accurate positioning, tend to be challenged by ranging bias in harsh environments. The emerging learning-based methods for error ...

Deep Generative Model for Simultaneous Range Error Mitigation and Environment Identification 

Li, X.; Mazuelas, S.Autoridad BCAM; Shen, Y. (2021-12-07)
Received waveforms contain rich information for both range information and environment semantics. However, its full potential is hard to exploit under multipath and non-line- of-sight conditions. This paper proposes a ...

Location Awareness in Beyond 5G Networks 

Conti, A.; Morselli, F.; Liu, Z.; Bartoletti, S.; Mazuelas, S.Autoridad BCAM; Lindsey, W.C.; Win, M.Z. (2021-11-01)
Location awareness is essential for enabling contextual services and for improving network management in 5th generation (5G) and beyond 5G (B5G) networks. This paper provides an overview of the expanding opportunities ...
