Artificial intelligence in all its forms is increasingly interwoven into all our lives, and remains one of the most lively areas of discussion and interest in technology today.This book presents the proceedings of the 20th International Conference of the Catalan Association for Artificial Intelligence (CCIA’2017): ‘Recent Advances in Artificial Intelligence Research and Development’, held in Deltebre, Terres de l'Ebre, Spain, in October 2017. Despite its title, this annual conference is not only for researchers from the Catalan Countries, but is an international event which attracts participants from countries all around the world. In total, 41 original contributions were submitted to CCIA’2017. Of these, 21 were accepted as long papers for oral presentation and 13 were accepted as short papers to be presented as posters. These 34 submissions appear in this book organized around a number of different topics including: agents and multi-agent systems; artificial vision and image processing; machine learning; artificial neural networks; cognitive modeling; fuzzy logic and reasoning; robotics; and AI applications. The book also includes abstracts of the 3 presentations by invited speakers.The book offers a representative sample of the current state of the art in the artificial intelligence community, and will be of interest to all those working with AI worldwide.

Mapping and localization are two essential tasks in autonomous mobile robotics. Due to the unavoidable noise that sensors present, mapping algorithms usually rely on loop closure detection techniques, which entail the correct identification of previously seen places to reduce the uncertainty of the resulting maps. This book deals with the problem of generating topological maps of the environment using efficient appearance-based loop closure detection techniques. Since the quality of a visual loop closure detection algorithm is related to the image description method and its ability to index previously seen images, several methods for loop closure detection adopting different approaches are developed and assessed. Then, these methods are used in three novel topological mapping algorithms. The results obtained indicate that the solutions proposed attain a better performance than several state-of-the-art approaches. To conclude, given that loop closure detection is also a key componentin other research areas, a multi-threaded image mosaicing algorithm is proposed. This approach makes use of one of the loop closure detection techniques previously introduced in order to find overlapping pairs between images and finally obtain seamless mosaics of different environments in a reasonable amount of time.

El diablo llegó a América protegido por el imaginario colectivo y el mito tradicional, pero los autores del discurso contra la magia y los propios colonizadores afirmaron que siempre había estado allí, fungiendo como señor de los naturales, proclamándose dios entre las supersticiones y las idolatrías. Así que fue necesario gestionar en la continuidad de los discursos que alertaban, aleccionaban y protegían contra un enemigo capaz de disfrazarse y adoptar formas rituales autóctonas; comenzó entonces una nueva etapa en la redacción de textos asimilados a la tradición del discurso demonológico. La atención se centró en la idolatría; el enfoque remozó su prejuicio diferenciador, y el formato recurrió al tratado, al informe, y la literatura. En el presente libro se analizan algunas muestras representativas de este proceso cultural acaecido en la época novohispana, pero detectable aún bajo las bases de nuestra idiosincrasia, a la luz de la teoría que Occidente había legado para comprender la presencia del mal y sus representantes en el mundo.

Esta novela epistolar muestra cuan intensa puede ser la narrativa confesional para revelar pasiones que definen los destinos de los actores de la tragicomedia que llamamos vida real. Acaso dolorosas, acaso tristes, dichas confesiones acontecen para mostrar el significado de la existencia.Al escribir los recuerdos de su infancia, Mario Quiroga descubre los complejos caminos de la memoria y reafirma la extraordinaria identidad de su anorada Violeta, la joven que llego a su vida para protegerlo, ilustrarlo y mostrarle un horizonte diferente de sentimientos, pensamientos y vivencias. Desde su presente, el narrador instala a Violeta en el centro de los hechos que marcaron su pasado; su propia labor confesional es una muestra de devocion hacia tan extraordinario ser.Conforme pasa de la edad infantil a la adolescencia, Mario comprende el mundo y forja su caracter gracias a Violeta y a los acontecimientos fa-miliares, amorosos y escolares que los rodean. Con el tiempo, los lazos se rompen o fortalecen de acuerdo a las decisiones del corazon o a la fuerza del caprichoso destino.A traves de las cartas que redacta para su sobrina, el devoto amigo rinde homenaje a su intima amiga, al tiempo que revela los conflictos de dos familias diferentes obligadas a relacionarse por el caprichoso azar y las pulsiones humanas. Tales factores pertenecen a un mundo que ya no existe mas; sin embargo, son trascendentes, a tal grado que lo alcanzan hasta enfrentarlo a tragicos acontecimientos.
