    Learning STRIPS Action Models with Classical Planning

    Full text link
    This paper presents a novel approach for learning STRIPS action models from examples that compiles this inductive learning task into a classical planning task. Interestingly, the compilation approach is flexible to different amounts of available input knowledge; the learning examples can range from a set of plans (with their corresponding initial and final states) to just a pair of initial and final states (no intermediate action or state is given). Moreover, the compilation accepts partially specified action models and it can be used to validate whether the observation of a plan execution follows a given STRIPS action model, even if this model is not fully specified.Comment: 8+1 pages, 4 figures, 6 table

    Esta comunicación narra la experiencia de la aplicación de un Ciclo de Mejora Docente con un modelo didáctico basado en la investigación y en la reelaboración de las ideas de los estudiantes, dentro del marco de la asignatura optativa “Temas de Lingüística General” del cuarto curso correspondiente al Grado de Filología Hispánica y al Doble Grado de Hispánica y Clásica, impartido en la Universidad de Sevilla durante el segundo cuatrimestre del ejercicio docente 2017/2018. Con una muestra total de 8 alumnos participantes, hemos obtenido unos resultados muy favorables que nos indican la necesaria implantación de este tipo de innovaciones educativas y animan a seguir indagando en el tema con una muestra mayor que corrobore las positivas evidencias aportadas mostradas en este Ciclo de Mejora, que, a su vez, nos han permitido concluir con la consolidación de unos principios didácticos que se llevarán a cabo en los futuros ejercicios docentes

    The current era is characterized by the exchange of information between people around the world. In this way, medical translation is one of the essential tasks in the area of Health Sciences. For this reason, the purpose of this undergraduate dissertation is to study the field of medical translation by explaining the difficulties and translation processes applied in a practical case: a research article. The project uses the previous analysis of the text as a fundamental tool for the translation of scientific texts, as well as parallel texts in English and Spanish. The result of this project provides answers to several relevant questions that must be taken into account during the translation of medical texts. Finally, it can be observed how previous analysis and translation procedures are crucial in the proposed translation of the article Surgery for Drug- Resistant Epilepsy in Children.La época actual esta caracterizada por el intercambio de información entre personas de todo el mundo. De este modo, la traducción médica es una de las tareas más importantes en el área de las ciencias de la salud. Por este motivo, el propósito de este trabajo de fin de grado es analizar el campo de la traducción médica exponiendo las dificultades y los procesos de traducción aplicados en un caso práctico: un artículo de investigación. Este trabajo utiliza el análisis previo del texto como herramienta básica para la traducción de textos científicos, así como textos paralelos en inglés y en español. El resultado de este proyecto aporta respuestas a varias preguntas relevantes que hay que tener en cuenta durante la traducción de textos médicos. Finalmente, el lector podrá comprobar cómo los análisis previos y los procedimientos de traducción son cruciales en la propuesta de traducción del artículo Surgery for Drug-Resistant Epilepsy in Children.Grado en Estudios Inglese

    Stochastic models and methods for the assessment of earthquake risk in insurance

    The problem of earthquake risk assessment and management in insurance is a challenging one at the interface of geophysics, engineering seismology, stochastics, insurance mathematics and economics. In this work, I propose stochastic models and methods for the assessment of earthquake risk from an insurer's point of view, where the aim is not to address problems in the financial mathematics and economics of risk selection, pricing, portfolio management, and risk transfer strategies such as reinsurance and securitisation, but to enable the latter through the characterisation of the foundation of any risk management consideration in insurance: the distribution of losses over a period of time for a portfolio of risks. Insurance losses are assumed to be generated by a loss process that is in turn governed by an earthquake process, a point process marked with the earthquake's hypocentre and magnitude, and a conditional loss distribution for an insurance portfolio, governing the loss size given the hypocentre and magnitude of the earthquake, and the physical characteristics of the portfolio as described in the individual policy records. From the modeling perspective, I examine the (non-trivial) minutiae around the infrastructure underpinning the loss process. A novel model of the earthquake process, a Poisson marked point process with spatial gamma intensity measure on the hypocentral space, and extensions of the Poisson and stress release models through the inclusion of hypocentral location in the mark, are proposed. I discuss the general architectural considerations for constructing the conditional loss distribution, and propose a new model as an alternative to the traditional ground motion attenuation and seismic vulnerability approach in engineering risk assessment. On the actuarial mathematics front, given a fully specified loss process, I address the problem of constructing simulation based and, where possible, analytical approximations to the distribution of portfolio losses over a period of time. I illustrate the applicability of the stochastic models and methods proposed in this work through the analysis of a residential homeowners property catastrophe portfolio exposed to earthquake risk in California. I construct approximations to the distribution of portfolio losses over a period of time under each of the three models of the earthquake process that I propose, and discuss their relative merits
