Making Cortically-Inspired Sensorimotor Control Realistic for Robotics: Design of an Extended Parallel Cellular Programming Model

Colloque avec actes et comité de lecture. internationale.International audienceThis paper introduces a multi-layer software architecture, that allows smart design and implementation of complex cortical neural networks, and efficient parallel execution on multiprocessor machines. The developer implements cortical networks sticking to their natural fine grained formalism, without caring about its mapping on coarse grained parallel computers. The developer can use a set of graphical tools to easily develop and debug the cortical systems. Some experiments of new cortical model design on multiprocessor PCs are introduced, and some performance measurements are given. This software suite is operational and currently in use in our laboratory to control a robotic am through cortical neural networks running on multiprocessor PCs

Towards a Security Enabled and SOA-based QoS (for the Smart Grid) Architecture

QoS and Security features are playing an important role in modern network architecures. Dynamic selection of services and by extension of service providers are vital in today’s liberalized market of energy. On the other hand it is equally important for Service Providers to spot the one QoS Module that offers the best QoS level in a given cost. Type of service, response time, availability and cost, consist a basic set of attributes that should be taken into consideration when building a concrete Grid network. In the proposed QoS architecture Prosumers request services based on the aforementioned set of attributes. The Prosumer requests the service through the QoS Module. It is then the QoS Module that seeks the Service Provider that best fits the needs of the client. The aforementioned approach is well supplemented with an in depth analysis on existing authentication and authorization protocols. The authors believe that QoS and security can work in parallel without adding extra burden in the Smart Grid infrastructure. This is feasible by building an in advance system for placing, scheduling, and assigning of the requests for energy consumption or production, thus decongesting the traffic in the whole network

Towards an adaptive SOA-based QoS & Demand-Response Provisioning Architecture for the Smart Grid

Dynamic selection of services and by extension of service providers are vital in today’s liberalized market of energy. On the other hand it is equally important for Service Providers to spot the one QoS Module that offers the best QoS level in a given cost. Type of service, response time, throughput, availability and cost, consist a basic set of attributes that should be taken into consideration when building a concrete Grid network. In the proposed QoS architecture Prosumers request services based on the aforementioned set of attributes. The Prosumer requests the service through the QoS Module. It is then the QoS Module that seeks the Service Provider that best fits the needs of the client. The aforementioned approach is well supplemented with a data analytics/machine learning architecture to further enrich the provisioning aspect this work is bringing to the Smart Grid market of energy

A takeover time-driven adaptive evolutionary algorithm for mobile user tracking in pre-5G cellular networks

Cellular networks are one of today’s most popular means of communication. This fact has made the mobile phone industry subject to a huge scientific and economic competition, where the quality of service is key. Such a quality is measured on the basis of reliability, speed and accuracy when delivering a service to a user no matter his location or behaviour are. This fact has placed the users’ tracking process among the most difficult and determining issues in cellular network design. In this paper, we present an adaptive bi-phased evolutionary algorithm based on the takeover time to solve this problem. The proposal is thoroughly assessed by tackling twenty-five real-world instances of different sizes. Twenty-eight of the state-of-the-art techniques devised to address the users’ mobility problem have been taken as the comparison basis, and several statistical tests have been also conducted. Experiments have demonstrated that our solver outperforms most of the top-ranked algorithms.This research is partially funded by the Universidad de Málaga, Consejería de Economía y Conocimiento de la Junta de Andalucía and FEDER under grant number UMA18-FEDERJA-003 (PRECOG); MCIN/AEI/10.13039/501100011033 under grant number PID 2020-116727RB-I00 (HUmove) and under TAILOR ICT-48 Network (No952215) funded by EU Horizon 2020 research and innovation programme.

SABACO: Extensiones a los Algoritmos de Optimización basados en Colonias de Hormigas para la Toma de Decisiones Influenciada por Emociones y el Aprendizaje de Secuencias Contextuales en Ambientes Inteligentes

En el trabajo que presentamos en esta tesis hacemos inicialmente una revisión de cómo ha ido evolucionando la interacción hombre máquina en el contexto de la computación, desde los primeros y escasos computadores hasta el momento actual, en el que los avances tecnológicos han permitido que, en muchos de los escenarios en los que se desarrolla nuestra vida diaria, estemos rodeados de diversos dispositivos electrónicos con los que interactuamos para hacer uso de alguno de los servicios que ofrecen. Veremos cómo esta difusión tecnológica ha introducido los sistemas de información en ámbitos más allá del contexto del trabajo, como la educación o el hogar, haciendo necesario que se tenga en cuenta en el diseño de los sistemas no sólo la funcionalidad o facilidad de uso sino también otros factores como la experiencia de uso o las emociones que siente una persona al interactuar con el sistema. Además, ha dado lugar a la aparición de los conocidos como ambientes inteligentes, en los que son los sistemas presentes en el entorno los que deben adaptarse al usuario y al contexto en el que se encuentra, adaptación que, dados los nuevos contextos en los tiene lugar la interacción con el usuario, plantea algunos retos. En particular, en el presente trabajo identificamos dos factores clave que los ambientes inteligentes deben tener en cuenta para tomar las decisiones y llevar a cabo las acciones adecuadas para conseguir una mejor adaptación al usuario y al contexto. Estos factores son la influencia de las emociones en la interacción y la utilización de la información contextual histórica. Por ello hacemos una revisión tanto de las propuestas de sistemas de decisión influenciados por emociones existentes en el área de la computación afectiva, como de las propuestas de sistemas sensibles al contexto, mostrando propuestas basadas en sistemas multiagente, redes neuronales, modelos ocultos de Markov, e introduciendo las técnicas metaheurísticas. Recientemente parece haber un sentimiento en la comunidad investigadora sobre la necesidad de aproximaciones híbridas para resolver problemas reales, no existe por desgracia una base sistemática que describa de forma rigurosa como proceder para combinar las distintas aproximaciones existentes.Mocholí Agües, JA.
