Concept design of a multiwavelength aerosol lidar system with mitigated diattenuation effects and depolarization-measurement capability
(EDP Sciences, 2015)
Conference lecture
Open AccessIt is known that the retrieval of aerosol extinction and backscatter coefficients from lidar data acquired through so-called total-power channels – intended to measure the backscattered power irrespective of the polarization ... -
Characterization of THz radiation by collimated wavefront aperture raster scanning
(Universidad de Málaga, 2020)
Conference report
Open AccessWe present measurements for characterization of the beam profile and polarization pattern of lens-coupled photoconductive antennas (PCAs) at THz frequencies using a setup with antennas at fixed positions and a movable ... -
Syntax-driven iterative expansion language models for controllable text generation
(Association for Computational Linguistics, 2020)
Conference lecture
Open AccessThe dominant language modeling paradigm handles text as a sequence of discrete tokens. While that approach can capture the latent structure of the text, it is inherently constrained to sequential dynamics for text generation. ... -
Enhancing word embeddings with knowledge extracted from lexical resources
(Association for Computational Linguistics, 2020)
Conference lecture
Open AccessIn this work, we present an effective method for semantic specialization of word vector representations. To this end, we use traditional word embeddings and apply specialization methods to better capture semantic relations ... -
Findings of the first shared task on lifelong learning machine translation
(Association for Computational Linguistics, 2020)
Conference lecture
Open AccessA lifelong learning system can adapt to new data without forgetting previously acquired knowledge. In this paper, we introduce the first benchmark for lifelong learning machine translation. For this purpose, we provide ... -
The TALP-UPC system description for WMT20 news translation task: multilingual adaptation for low resource MT
(Association for Computational Linguistics, 2020)
Conference lecture
Open AccessIn this article, we describe the TALP-UPC participation in the WMT20 news translation shared task for Tamil-English. Given the low amount of parallel training data, we resort to adapt the task to a multilingual system to ... -
Continual lifelong learning in natural language processing: a survey
(Association for Computational Linguistics, 2020)
Conference lecture
Open AccessContinual learning (CL) aims to enable information systems to learn from a continuous data stream across time. However, it is difficult for existing deep learning architectures to learn a new task without largely forgetting ... -
Motional behavior estimation using simple spectral estimation: application to the off-shore wind lidar
(Institute of Electrical and Electronics Engineers (IEEE), 2020)
Conference report
Open AccessThis paper proposes two methods to estimate the so-called “characteristic motional period” of a floating wind-lidar buoy. These techniques aim to characterise the buoy's pitch and roll tilting as simple harmonic motions ... -
Floating Doppler Wind Lidar measurement of wind turbulence: a cluster analysis
(Institute of Electrical and Electronics Engineers (IEEE), 2020)
Conference report
Open AccessThe standard deviation of the Horizontal Wind Speed as a proxy of wind turbulence is used to compare the apparent wind turbulence measured by an off-shore floating Doppler lidar to the one measured by a fixed lidar on a ... -
Offshore Doppler Wind LiDAR assessment of atmospheric stability
(Institute of Electrical and Electronics Engineers (IEEE), 2020)
Conference report
Open AccessThis paper tackles atmospheric stability typing using a Zephyr™ 300 offshore Doppler Wind Lidar in the context of its progressive acceptance in the offshore wind-energy industry. The lidar-retrieved wind-shear exponent, ... -
Modelling multi-vendor transponders performance and optimizing launch power
(Institute of Electrical and Electronics Engineers (IEEE), 2020)
Conference report
Open AccessWe propose physical layer model extensions that capture the performance variations of multivendor transponders and use those with appropriate algorithms to optimize connections’ launch powers. We estimated potential SNR ... -
Filter features extraction from optical spectra
(Institute of Electrical and Electronics Engineers (IEEE), 2020)
Conference report
Open AccessWe propose a method to estimate the central frequency and the bandwidth of optical filters, that relies on optical spectra captured with optical channel monitors at ROADM’s ingress port. We demonstrate for both features ...
