1. 1. Optimisation of Clinical Trials using Bayesian Decision Theory

   Författare :Sebastian Jobjörnsson; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; decision theory; drug regulation; ; Bayesian statistics; subgroup analysis; clinical trials; health economics; multiple testing; decision theory;

   Sammanfattning : A decision maker confronted with the task of designing a clinical trial has to consider a multitude of aspects. Large trials lead to more evidence,which in turn makes it less likely that harmful decisions are taken when deciding on future treatments for patients. LÄS MER

3. 2. Pipe failure assessment and decision support system for a smart operation and maintenance : A comprehensive literature review and a conceptual decision analysis model proposal

   Författare :Roya Meydani; John Leander; Andreas Lindhe; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Urban pipeline systems’ rehabilitation; Infrastructure management; Decision-modeling; Decision analysis; Problem structuring; Uncertainty; Bayesian decision theory; Utility-based decision-making.; Urbana ledningssystemsunderhåll; Infrastruktur förvaltning; Beslutsmod- ellering; Beslutsanalys; Problembeskrivning; Osäkerhet; Bayesiansk beslutsteori; Nyttobaserad beslutsmodell; Bro- och stålbyggnad; Structural Engineering and Bridges;

   Sammanfattning : The reported research provides a rough guide to the best practice of decision modeling concerning urban pipeline systems’ rehabilitation. The thesis aims to bring attention to the fact that a proper decision-making model is a cornerstone for efficient infrastructure management. LÄS MER

4. 3. Efficient Bayesian Planning

   Författare :Divya Grover; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; POMDP; Partially Observable MDP; Planning; Bayesian Reinforcement Learning;

   Sammanfattning : Artificial Intelligence (AI) is a long-studied and yet very active field of research. The list of things differentiating humans from AI grows thinner but the dream of an artificial general intelligence remains elusive. LÄS MER

5. 4. Sample Efficient Bayesian Reinforcement Learning

   Författare :Divya Grover; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Decision Making under Uncertainty; Bayesian Reinforcement Learning; Model based Reinforcement Learning;

   Sammanfattning : Artificial Intelligence (AI) has been an active field of research for over a century now. The research field of AI may be grouped into various tasks that are expected from an intelligent agent; two major ones being learning & inference and planning . LÄS MER

7. 5. On the Optimisation and Regulation of Clinical Trials

   Författare :Sebastian Jobjörnsson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; decision theory; Bayesian statistics; optimal stopping.; clinical trials; subgroup analysis; drug regulation;

   Sammanfattning : The basic premise of this thesis is that Bayesian Decision Theory (BDT) can and should be used to solve clinical trial design problems. While the flexibility of the framework allows for accommodating a great variety of situations, it also requires an explicit consideration of the gains and costs associated with the trial. LÄS MER
