A Cognitive Framework for Imitation Learning
2006
Abstract In order to have a robotic system able to effectively learn by imitation, and not merely reproduce the movements of a human teacher, the system should have the capabilities of deeply understanding the perceived actions to be imitated. This paper deals with the development of cognitive architecture for learning by imitation in which a rich conceptual representation of the observed actions is built. The purpose of the following discussion is to show how this Conceptual Area can be employed to efficiently organize perceptual data, to learn movement primitives from human demonstration and to generate complex actions by combining and sequencing simpler ones. The proposed architecture ha…
An algebra for the manipulation of conceptual spaces in cognitive agents
2013
According to Gärdenfors, the theory of conceptual spaces describes a level of representation present in some cognitive agents between a sub-conceptual and a symbolic level of representation. In contrast to a large part of contemporary philosophical speculation on these matters for which concepts and conceptual content are propositional, conceptual spaces provide a geometric framework for the representation of concepts. In this paper we introduce an algebra for the manipulation of different conceptual spaces in order to formalise the process whereby an artificial agent rearranges its internal conceptual representations as a consequence of its perceptions, which are here rendered in terms of …
$varphi$-pairs and common fixed points in cone metric spaces
2008
In this paper we introduce a contractive condition, called $\varphi \textrm{-}pair$, for two mappings in the framework of cone metric spaces and we prove a theorem which assures existence and uniqueness of common fixed points for $\varphi \textrm{-}pairs$. Also we obtain a result on points of coincidence. These results extend and generalize well-known comparable results in the literature.
Common fixed points in cone metric spaces for CJM-pairs
2011
Abstract In this paper we introduce some contractive conditions of Meir–Keeler type for two mappings, called f - M K -pair mappings and f - C J M -pair (from Ciric, Jachymski, and Matkowski) mappings, in the framework of regular cone metric spaces and we prove theorems which guarantee the existence and uniqueness of common fixed points. We give also a fixed point result for a multivalued mapping that satisfies a contractive condition of Meir–Keeler type. These results extend and generalize some recent results from the literature. To conclude the paper, we extend our main result to non-regular cone metric spaces by using the scalarization method of Du.
On fuzzification of topological categories
2014
This paper shows that (L,M)-fuzzy topology of U. Hohle, T. Kubiak and A. Sostak is an instance of a general fuzzification procedure for topological categories, which amounts to the construction of a new topological category from a given one. This fuzzification procedure motivates a partial dualization of the machinery of tower extension of topological constructs of D. Zhang, thereby providing the procedure of tower extension of topological categories. With the help of this dualization, we arrive at the meta-mathematical result that the concept of (L,M)-fuzzy topology and the notion of approach space of R. Lowen are ''dual'' to each other.
Invariant approximation results in cone metric spaces
2011
Some sufficient conditions for the existence of fixed point of mappings satisfying generalized weak contractive conditions is obtained. A fixed point theorem for nonexpansive mappings is also obtained. As an application, some invariant approximation results are derived in cone metric spaces.
Non absolutely convergent integrals of functions taking values in a locally convex space
2006
Properties of McShane and Kurzweil-Henstock integrable functions taking values in a locally convex space are considered and the relations with other integrals are studied. A convergence theorem for the Kurzweil-Henstock integral is given
Riemann type integrals for functions taking values in a locally convex space
2006
The McShane and Kurzweil-Henstock integrals for functions taking values in a locally convex space are defined and the relations with other integrals are studied. A characterization of locally convex spaces in which Henstock Lemma holds is given.
El aula como caja de resonancia para la creación sonora: nuevas arquitecturas y herramientas tecnológicas para acercar el arte sonoro al ámbito educa…
2019
RESUMEN: Este artículo reflexiona sobre la importancia de repensar los espacios que habitamos de acuerdo con la idea de que el mundo físico y el digital interactúen de manera natural. A partir de esta premisa, y en el ámbito educativo-musical, las prácticas desarrolladas en el MusicLAB CR-209 del IES Arabista Ribera de Carcaixent (Valencia) son una muestra de cómo estas nuevas arquitecturas pueden favorecer el desarrollo de la creatividad. Acorde con las posibilidades que ofrece la tecnología actual, esta aula laboratorio está concebido como un espacio para la experimentación y la improvisación. El objeto de este artículo es describir ?La Máquina Interestelar?, una propuesta pedagógica inte…
Spaces of Identity: Gender, Ethnicity, and Race in Salome of the Tenements (1923) and Quicksand (1928)
2018
Abstract The 1920s marked a fervent time for artistic and literary expression in the United States. Besides the famous authors of the decade, including F. Scott Fitzgerald, Ernest Hemingway, and William Faulkner, Anzia Yezierska and Nella Larsen, among other female writers, also managed to carve “a literary space” for their stories. Yezierska and Larsen depicted the struggles and tribulations of minority women during the fermenting 1920s, with a view to illustrating the impact of ethnicity and race on the individual female identity. Yezierska, a Jewish-American immigrant, and Larsen, a biracial American woman, share an interest in capturing the nuances of belonging to a particular community…
