    Characterization of autoregressive processes using entropic quantifiers

    Get PDF
    The aim of the contribution is to introduce a novel information plane, the causal-amplitude informational plane. As previous works seems to indicate, Bandt and Pompe methodology for estimating entropy does not allow to distinguish between probability distributions which could be fundamental for simulation or for probability analysis purposes. Once a time series is identified as stochastic by the causal complexity-entropy informational plane, the novel causal-amplitude gives a deeper understanding of the time series, quantifying both, the autocorrelation strength and the probability distribution of the data extracted from the generating processes. Two examples are presented, one from climate change model and the other from financial markets.Fil: Traversaro Varela, Francisco. Instituto Tecnológico de Buenos Aires; Argentina.

    Na esfera da cronoloxía dos cambios lingüísticos, o achado de novos textos antigos representa normalmente para a lingua galega unha oportunidade, moi esperada, de descubrir novas voces, novas acepcións, novos rexistros máis recuados delas, mais son contadas as ocasións nas que, na actualidade, saen da escuridade datos que modifican substancialmente o marco cronolóxico xeral do desenvolvemento dunha mudanza lingüística de longo percorrido temporal e de proxección diató- pica complexa. De haber almoedas fi lolóxicas, sería este o tipo de datos polos que se ofrecerían as sumas máis elevadas. Canto non estarían dispostos a ofrecer os historiadores da lingua por evidencias da existencia da gheada no período medieval, por falar dun cambio emblemático

    Youth itineraries, individuation, and reflexivities: approaches to social participation in low-income metropolitan neighborhoods

    En este artículo se presenta un análisis de itinerarios de individuación, en atención a las formas de participación y reflexividad de personas jóvenes que viven en barrios populares de tres áreas metropolitanas: Buenos Aires/Argentina, Porto Alegre/Brasil y Santiago/Chile. Para ello, se articulan resultados de diferentes estudios empíricos desarrollados entre 2013 y 2019, con herramientas conceptuales de la sociología del individuo de Danilo Martuccelli, especialmente las nociones de pruebas, soportes y texturas sociales. En primer lugar, se abordan los referentes teóricos utilizados para el despliegue del problema y las estrategias metodológicas utilizadas para la construcción y el análisis de las narrativas juveniles. Posteriormente, se realiza la interpretación del corpus de datos en torno a dos ejes centrales: a) territorios, actores e intermundos populares; b) jóvenes, participación social y reflexividades. Las personas jóvenes enfrentan, en diversos territorios populares, una pluralidad de coerciones materiales y simbólicas. Sin embargo, allí también traman espacios colectivos donde establecen identificaciones personales y grupales, cuando descubren o generan propuestas deportivas, artístico-políticas y educativas. En estas, producen vínculos intergeneracionales, recuperan saberes ancestrales y construyen marcos referenciales y reflexivos, volviendo la territorialidad un soporte y un signo de reconocimiento. En este sentido, el estudio de las narrativas juveniles constituye una herramienta privilegiada para el análisis de las agencias y las individualidades populares latinoamericanas.This study analyzes individuation itineraries by considering the forms of participation and reflexivity of young people who live in low-income neighborhoods in three metropolitan areas: Buenos Aires/Argentina, Porto Alegre/Brazil, and Santiago/Chile. For this, this study articulated the results of several empirical studies conducted from 2013 to 2019 with the conceptual tools in Danilo Martuccelli’s sociology of the individual, especially its notions of tests, supports, and social textures. This research first addresses theoretical frameworks to implement its problem and methodological strategies to build and analyze youth’s narratives. Then, it interpreted its data corpus around two central axes: a) low-income territories, actors, and interworlds and b) young people, social participation, and reflexivities. Young people face a plurality of material and symbolic coercions in several low-income territories. However, these territories also create collective spaces in which youths establish personal and group identifications as they discover or generate sports, artistic-political, and educational proposals, which create intergenerational bonds, recover ancestral knowledge, and build referential and reflective landmarks, transforming territorialities into supports and a sign of recognition. Thus, studying youth narratives offers a privileged tool to analyze Latin American low-income agencies and individualities

    Forest fire prediction using fuzzy prototypical knowledge discovery

    An application of Zadeh’s prototype theory in the Knowledge Acquisition process, is presented here, and as a practical example, to define a method for predicting the evolution of the forest fire occurrence-danger rate in INCEND-IA: A KBS for prediction and decision support in fighting against forest fires. This method then allows us to interpret any real cyclical situation using a previously discovered paradigm and define the current period. The FPKD (Fuzzy Prototypical Knowledge Discovery) is presented as a mechanism with the aim of generating Prototypes of Data (A new set of data sufficiently representative to be able to summarize or assimilate the behavior of any of the remaining data); but the concept of prototype is a fuzzy concept and Zadeh’s Theory provides an appropriate framework for its application. Data Mining techniques have been used (decision trees, time series, clustering...). Thus, it is possible to calculate the grade of compatibility of a real situation with the prototypes and define the current period using these affinity values, with the objective of predicting the evolution of the following daysI Workshop de Agentes y Sistemas Inteligentes (WASI)Red de Universidades con Carreras en Informática (RedUNCI
