Journal ArticleDOI
Clustering-Based Hyperspectral Band Selection Using Information Measures
TL;DR: This paper presents a technique for dimensionality reduction to deal with hyperspectral images based on a hierarchical clustering structure to group bands to minimize the intracluster variance and maximize the intercluster variance.
Proceedings ArticleDOI
UJIIndoorLoc: A new multi-building and multi-floor database for WLAN fingerprint-based indoor localization problems
Joaquín Torres-Sospedra,Raúl Montoliu,Adolfo Martínez-Usó,Joan Avariento,Tomas J. Arnau,Mauri Benedito-Bordonau,Joaquín Huerta +6 more
TL;DR: A multi-building and multi-floor localization database based on WLAN fingerprinting is presented, which not only is the biggest database in the literature but it is also the first publicly available database.
Journal ArticleDOI
Item response theory in AI: Analysing machine learning classifiers at the instance level
TL;DR: IRT suits classification tasks perfectly, where instances correspond to items and classifiers correspond to respondents and how the estimated classifier ability can be used to compare classifier performance in a different way through classifier characteristic curves is seen.
Proceedings ArticleDOI
Making sense of item response theory in machine learning
TL;DR: In this paper, a series of experiments with a range of datasets and classification methods are performed to fully understand how IRT works and what their parameters really mean in the context of machine learning.
Journal ArticleDOI
Multidimensional Optical Sensing and Imaging System (MOSIS): From Macroscales to Microscales
Bahram Javidi,Xin Shen,Adam Markman,Pedro Latorre-Carmona,Adolfo Martínez-Usó,José Martínez Sotoca,Filiberto Pla,Manuel Martínez-Corral,Genaro Saavedra,Yi-Pai Huang,Adrian Stern +10 more
TL;DR: In this article, the authors describe passive multidimensional imaging systems combined with different integral imaging configurations, which can be used for 3D visualization, seeing through obscurations, material inspection, and object recognition from microscales to long range imaging.
