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

(2021-11-16)
This thesis includes 3 contributions of different types to the area of supervised time series classification, a growing field of research due to the amount of time series collected daily in a wide variety of domains. In ...
Location Awareness in Beyond 5G Networks
(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 ...
Statistical assessment of experimental results: a graphical approach for comparing algorithms
(2021-08-25)
Non-deterministic measurements are common in real-world scenarios: the performance of a stochastic optimization algorithm or the total reward of a reinforcement learning agent in a chaotic environment are just two examples ...
On the symmetry of the Quadratic Assignment Problem through Elementary Landscape Decomposition
(2021-07)
When designing meta-heuristic strategies to optimize the quadratic assignment problem (QAP), it is important to take into account the specific characteristics of the instance to be solved. One of the characteristics that ...
A cheap feature selection approach for the K -means algorithm
(2021-05)
The increase in the number of features that need to be analyzed in a wide variety of areas, such as genome sequencing, computer vision or sensor networks, represents a challenge for the K-means algorithm. In this regard, ...
Efficient meta-heuristics for spacecraft trajectory optimization
(2021-03)
Meta-heuristics has a long tradition in computer science. During the past few years, different types of meta-heuristics, specially evolutionary algorithms got noticeable attention in dealing with real-world optimization ...
