A Novel Hybrid Scheme Using Genetic Algorithms and Deep Learning for the Reconstruction of Portuguese Tile Panels

This paper presents a novel scheme, based on a unique combination of genetic algorithms (GAs) and deep learning (DL), for the automatic reconstruction of Portuguese tile panels, a challenging real-world variant of the jigsaw puzzle problem (JPP) with important national heritage implications. Specifically, we introduce an enhanced GA-based puzzle solver, whose integration with a novel DL-based compatibility measure (DLCM) yields state-of-the-art performance, regarding the above application. Current compatibility measures consider typically (the chromatic information of) edge pixels (between adjacent tiles), and help achieve high accuracy for the synthetic JPP variant. However, such measures exhibit rather poor performance when applied to the Portuguese tile panels, which are susceptible to various real-world effects, e.g., monochromatic panels, non-squared tiles, edge degradation, etc. To overcome such difficulties, we have developed a novel DLCM to extract high-level texture/color statistics from the entire tile information. Integrating this measure with our enhanced GA-based puzzle solver, we have demonstrated, for the first time, how to deal most effectively with large-scale real-world problems, such as the Portuguese tile problem. Specifically, we have achieved 82% accuracy for the reconstruction of Portuguese tile panels with unknown piece rotation and puzzle dimension (compared to merely 3.5% average accuracy achieved by the best method known for solving this problem variant). The proposed method outperforms even human experts in several cases, correcting their mistakes in the manual tile assembly

Chapitre V. La glose

Dans la poésie espagnole, la Glose consiste dans un texte de quelques vers, suivi de strophes aussi nombreuses que les vers de ce texte, dont chacun, à tour de rôle, reparaît à la fin de chaque strophe. Au-delà des Pyrénées, ce genre est représenté par un très grand nombre de pièces. Je transcris l'exemple suivant, qui a pour auteur le licencié Juan Lopez de Ubeda, dont le Cançoniero y Vergel de Plantas divinas date de 1588 : Ojos, cejas y cabellos,Puso el cielo todo en vos;Que à no conocer a..

Social Awareness and Ideology: Self-Assessment and Socio-Civic Knowledge Competence

"The fundamental cause of the trouble is that in the modern world the stupid are cocksure while the intelligent are full of doubt" (Russell, 1933, p. 28). One seldom hears doubt in the espousing of socio-civic, cultural, or political pronouncements. While the voices seem to always be “cocksure;” we first ask at what level is their objective knowledge and how well do they self-assess that knowledge? We explore how ideological positioning is related to self-assessment and objective knowledge. We conducted a non-comparative (absolute) quantitative study through an email survey of 330 residents of the U.S. over the age of 18 that examined objective socio-civic knowledge and self-assessed ideology and wokeness. The experimental results confirmed misestimations consistent with Dunning-Kruger Effects
