Semantic discovery and reuse of business process patterns
Patterns currently play an important role in modern information systems (IS) development and their use has mainly been restricted to the design and implementation phases of the development lifecycle. Given the increasing significance of business modelling in IS development, patterns have the potential of providing a viable solution for promoting reusability of recurrent generalized models in the very early stages of development. As a statement of research-in-progress this paper focuses on business process patterns and proposes an initial methodological framework for the discovery and reuse of business process patterns within the IS development lifecycle. The framework borrows ideas from the domain engineering literature and proposes the use of semantics to drive both the discovery of patterns as well as their reuse
Booleovská faktorová analýza atraktorovou neuronovou sítí
Import 23/08/2017Methods for the discovery of hidden structures of high-dimensional binary data rank among the most important challenges facing the community of machine learning researchers at present. There are many approaches in the literature that try to solve this hitherto rather ill-defined task. The Boolean factor analysis (BFA) studied in this work represents a hidden structure of binary data as Boolean superposition of binary factors complied with the BFA generative model of signals, and the criterion of optimality of BFA solution is given. In these terms, the BFA is a well-defined task completely analogous to linear factor analysis. The main contributions of the dissertation thesis are as follows: Firstly, an efficient BFA method, based on the original attractor neural network with increasing activity (ANNIA), which is subsequently improved through a combination with the expectation-maximization method(EM),so LANNIA method has been developed. Secondly, the characteristics of the ANNIA that are important for LANNIA and ANNIA methods functioning were analyzed. Then the functioning of both methods was validated on artificially generated data sets. Next, the method was applied to real-world data from different areas of science to demonstrate their contribution to this type of analysis. Finally, the BFA method was compared with related methods, including applicability analysis.Jednou z nejdůležitějších výzev současnosti, která stojí před komunitou badatelů z oblasti strojového učení je výzkum metod pro analýzu vysoce-dimenzionálních binárních dat s cílem odhalení jejich skryté struktury. V literatuře můžeme nalézt mnoho přístupů, které se snaží tuto doposud poněkud vágně definovanou úlohu řešit. Booleovská Faktorová Analýza (BFA), jež je předmětem této práce, předpokládá, že skrytou strukturu binárních dat lze reprezentovat jako booleovskou superpozici
binárních faktorů tak, aby co nejlépe odpovídala generativnímu modelu signálů BFA a danému kritériu optimálnosti. Za těchto podmínek je BFA dob��e definovaná úloha zcela analogická lineární faktorové analýze. Hlavní přínosy disertační práce, jsou následující: Za prvé byl vyvinut efektivní způsob BFA založený na původní atraktorové neuronové síti s rostoucí aktivitou (ANNIA), která byla následně zlepšena kombinací s metodou expectation–maximization (EM)a tak vytvo5ena metoda LANNIA. Dále byly provedeny analýzy charakteristik ANNIA, které jsou důležité pro fungování obou metod. Funkčnost obou metod byla také ověřena na uměle vytvořených souborech dat pokrývajících celou škálu parametrů generativního modelu. Dále je v práci ukázáno použití metod na reálných datech z různých oblastí vědy s cílem prokázat jejich přínos pro tento typ analýzy. A konečně bylo provedeno i srovnání metod BFA se podobnými metodami včetně analýzy jejich použitelnosti.460 - Katedra informatikyvyhově

Classificação de pacientes para adaptação de cadeira de rodas inteligente
Doutoramento em Engenharia InformáticaA importância e preocupação dedicadas à autonomia e independência das
pessoas idosas e dos pacientes que sofrem de algum tipo de deficiência tem
vindo a aumentar significativamente ao longo das últimas décadas. As
cadeiras de rodas inteligentes (CRI) são tecnologias que podem ajudar este
tipo de população a aumentar a sua autonomia, sendo atualmente uma área
de investigação bastante ativa. Contudo, a adaptação das CRIs a pacientes
específicos e a realização de experiências com utilizadores reais são assuntos
de estudo ainda muito pouco aprofundados.
A cadeira de rodas inteligente, desenvolvida no âmbito do Projeto IntellWheels,
é controlada a alto nível utilizando uma interface multimodal flexível,
recorrendo a comandos de voz, expressões faciais, movimentos de cabeça e
através de joystick. Este trabalho teve como finalidade a adaptação automática
da CRI atendendo às características dos potenciais utilizadores.
Foi desenvolvida uma metodologia capaz de criar um modelo do utilizador. A
investigação foi baseada num sistema de recolha de dados que permite obter
e armazenar dados de voz, expressões faciais, movimentos de cabeça e do
corpo dos pacientes. A utilização da CRI pode ser efetuada em diferentes
situações em ambiente real e simulado e um jogo sério foi desenvolvido
permitindo especificar um conjunto de tarefas a ser realizado pelos
utilizadores. Os dados foram analisados recorrendo a métodos de extração de
conhecimento, de modo a obter o modelo dos utilizadores. Usando os
resultados obtidos pelo sistema de classificação, foi criada uma metodologia
que permite selecionar a melhor interface e linguagem de comando da cadeira
para cada utilizador.
A avaliação para validação da abordagem foi realizada no âmbito do Projeto
FCT/RIPD/ADA/109636/2009 - "IntellWheels - Intelligent Wheelchair with
Flexible Multimodal Interface". As experiências envolveram um vasto conjunto
de indivíduos que sofrem de diversos níveis de deficiência, em estreita
colaboração com a Escola Superior de Tecnologia de Saúde do Porto e a
Associação do Porto de Paralisia Cerebral. Os dados recolhidos através das
experiências de navegação na CRI foram acompanhados por questionários
preenchidos pelos utilizadores. Estes dados foram analisados estatisticamente,
a fim de provar a eficácia e usabilidade na adequação da interface da CRI ao
utilizador. Os resultados mostraram, em ambiente simulado, um valor de
usabilidade do sistema de 67, baseado na opinião de uma amostra de
pacientes que apresentam os graus IV e V (os mais severos) de Paralisia
Cerebral. Foi também demonstrado estatisticamente que a interface atribuída
automaticamente pela ferramenta tem uma avaliação superior à sugerida pelos
técnicos de Terapia Ocupacional, mostrando a possibilidade de atribuir
automaticamente uma linguagem de comando adaptada a cada utilizador.
Experiências realizadas com distintos modos de controlo revelaram a
preferência dos utilizadores por um controlo compartilhado com um nível de
ajuda associado ao nível de constrangimento do paciente. Em conclusão, este
trabalho demonstra que é possível adaptar automaticamente uma CRI ao
utilizador com claros benefícios a nível de usabilidade e segurança.The importance and concern given to the autonomy and independence of
elderly people and patients suffering from some kind of disability has been
growing significantly in the last few decades. Intelligent wheelchairs (IW) are
technologies that can increase the autonomy and independence of this kind of
population and are nowadays a very active research area. However, the
adaptations to users’ specificities and experiments with real users are topics
that lack deeper studies.
The intelligent wheelchair, developed in the context of the IntellWheels project,
is controlled at a high-level through a flexible multimodal interface, using voice
commands, facial expressions, head movements and joystick as its main input
modalities. This work intended to develop a system enabling the automatic
adaptation, to the user characteristics, of the previously developed intelligent
wheelchair.
A methodology was created enabling the creation of a user model. The
research was based on the development of a data gathering system, enabling
the collection and storage of data from voice commands, facial expressions,
head and body movements from several patients with distinct disabilities such
as Cerebral Palsy. The wheelchair can be used in different situations in real
and simulated environments and a serious game was developed where
different tasks may be performed by users.
Data was analysed using knowledge discovery methods in order to create an
automatic patient classification system. Based on the classification system, a
methodology was developed enabling to select the best wheelchair interface
and command language for each patient.
Evaluation was performed in the context of Project FCT/RIPD/ADA/109636/
2009 – “IntellWheels – Intelligent Wheelchair with Flexible Multimodal
Interface”. Experiments were conducted, using a large set of patients suffering
from severe physical constraints in close collaboration with Escola Superior de
Tecnologia de Saúde do Porto and Associação do Porto de Paralisia Cerebral.
The experiments using the intelligent wheelchair were followed by user
questionnaires. The results were statistically analysed in order to prove the
effectiveness and usability of the adaptation of the Intelligent Wheelchair
multimodal interface to the user characteristics. The results obtained in a
simulated environment showed a 67 score on the system usability scale based
in the opinion of a sample of cerebral palsy patients with the most severe cases
IV and V of the Gross Motor Function Scale. It was also statistically
demonstrated that the data analysis system advised the use of an adapted
interface with higher evaluation than the one suggested by the occupational
therapists, showing the usefulness of defining a command language adapted to
each user. Experiments conducted with distinct control modes revealed the
users' preference for a shared control with an aid level taking into account the
level of constraint of the patient. In conclusion, this work demonstrates that it is
possible to adapt an intelligent wheelchair to the user with clear usability and
safety benefits
