Trustworthy explanations : Improved decision support through well-calibrated uncertainty quantification
- 2023
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The use of Artificial Intelligence (AI) has transformed fields like disease diagnosis and defence. Utilising sophisticated Machine Learning (ML) models, AI predicts future events based on historical data, introducing complexity that challenges understanding and decision-making. Previous research emphasizes users’ difficulty discerning when to trust predictions due to model complexity, underscoring addressing model complexity and providing transparent explanations as pivotal for facilitating high-quality decisions.Many ML models offer probability estimates for predictions, commonly used in methods providing explanations to guide users on prediction confidence. However, these probabilities often do not accurately reflect the actual distribution in the data, leading to potential user misinterpretation of prediction trustworthiness. Additionally, most explanation methods fail to convey whether the model’s probability is linked to any uncertainty, further diminishing the reliability of the explanations.Evaluating the quality of explanations for decision support is challenging, and although highlighted as essential in research, there are no benchmark criteria for comparative evaluations.This thesis introduces an innovative explanation method that generates reliable explanations, incorporating uncertainty information supporting users in determining when to trust the model’s predictions. The thesis also outlines strategies for evaluating explanation quality and facilitating comparative evaluations. Through empirical evaluations and user studies, the thesis provides practical insights to support decision-making utilising complex ML models.

- Research projects have an inherent risk of failure, and learning howto cope with the risk is an important task for everyone involved. In order to doso it is necessary to share the knowledge of the experiences done during andafter the project. This paper investigates a recently completed enterprisemodeling research project and contributes with lessons learned andrecommendations for future enterprise modeling projects.

Konferensbidrag (refereegranskat)abstract
- A clear understanding of the organizational competences of anenterprise and the underlying individual competences and the competencedevelopment needs has become more and more important for many industrialareas as a foundation for competence supply processes and adjustment tochanging market conditions. Competence modelling, i.e. the use of enterprisemodelling techniques for capturing existing and describing desiredorganisational and individual competences in enterprises, offers importantcontributions to this. In the last years, the authors of the paper have performed anumber of competence modelling cases, which revealed different characteristicsand resulted in lessons learned. This paper presents an examination of differentcharacteristics of competence modelling cases, and recommendations andlessons learned from these cases for the practice of competence modelling.

The Evolution of the Connector View Concept : Enterprise Models for Interoperability Solutions in the Extended Enterprise
- 2011
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- People around the world who are working in companies and organisations need to collaborate, and in their collaboration use information managed by different information systems. The requirements of information systems to be interoperable are therefore apparant. While the technical problems, of communicating or sharing information between different information systems, have become less difficult to solve, the attention has turned to other aspects of interoperability. Such aspects concern the bussiness processes, the knowledge, the syntax and the semantics that involves the information managed by information systems.Enterprise modelling is widely used to achieve integration solutions within enterprises and is a research area both for the integration wihin an enterprise (company or organisation) and the integration between several different enterprises. Enterprise modelling takes into account several of the aspects, mentioned as important for interoperability, in the models that are created.This thesis describes a research which has resulted in the connector view concept. The main contribution with this framework comprises a model structure and an approach, for performing the modelling of the collaboration between several partners in an extended enterprise. The purpose of the enterprise models thus created, by using the connector view concept, is to find solutions to interoperability problems, that exist in the collaboration between several enterprises.

Collaborative practice : an action research approach to efficient ITSM
- 2011
-
Ingår i: 1 st International & Inter-disciplinary Workshop on Practice Research.
-
Konferensbidrag (refereegranskat)abstract
- This paper addresses collaborative research as an action research approach. Many times action research is described as embracing one research organisation and one business organisation. We are challenging this view by introducing the concept of collaborative practice. A collaborative practice can be seen as a cluster of local practices and researchers working together. In this way, a collaborative practice should enable joint learning between, and joint development efforts for, several business practices as well as contributing to general practice and the scientific body of knowledge. Based on a case study within efficient IT Service Management (ITSM), the concept of collaborative practice and its relation to other adjacent concepts (such as local practice, general practice and scientific body of knowledge) have been characterized. Our results should be viewed as preliminary since they are gathered from an ongoing project.
