2018 PROCEEDINGS OF THE THIRTIETH AAAI CONFERENCE ON ARTIFICIAL INTELLIGENCE AND THE TWENTY-EIGHTH INNOVATIVE APPLICATIONS OF ARTIFICIAL INTELLIGENCE CONFERENCE  
We assume the user compactly expresses her preferences via soft constraints. We consider a sequential procedure that uses Decision Field Theory to model the decision making on each variable.  ...  In the future, we plan to compare our results non-sequential approach and with behavioral data to asses our approach both in terms of modeling human decision making over complex domains, and adopting DFT  ...  We use soft constraints to support a deliberation process performed through decision field theory and we consider a sequential approach, where deliberation is applied to each variable.  ...

Sometimes it is not so bad to decide in a hurry: Influence of different levels of temporal opportunity on the elaboration of purchasing intention

Jean-Christophe Giger, Grzegorz Pochwatko
2008 Polish Psychological Bulletin  
Results show that in 5 second limit and unlimited time conditions, they rely more on an attitude-based decision strategy and chose the less optimal store.  ...  Participants made their choices under time pressure (either 5, 9 or 15 seconds) or were given unlimited time to deliberate.  ...  In line with Wilson et al. (1989) and Dijksterhuis (2004) , the present results also support the idea that deliberation can be maladaptive in making choice.  ...

Deliberating Collective Decisions

Jimmy Chan, Alessandro Lizzeri, Wing Suen, Leeat Yariv
2017 The Review of Economic Studies  
Second, more diverse preferences, more patient members, or more unanimous decision voting rules lead to lengthier deliberation and more accurate decisions.  ...  Three main insights emerge from our analysis and match an array of stylized facts on committee decision making.  ...  Because (2) and (3) are necessary for constrained maximization, this unique cutoff pair must be optimal in the constraint set. 10 Equilibrium Analysis Given decision rule k, define the lower pivotal  ...

Ru Han, Shuyao Liang, Clément François, Samuel Aballea, Emilie Clay, Mondher Toumi
2021 Journal of Market Access & Health Policy  
Methods: A constrained optimization modelling of resource allocation for the treatment of CHC was developed in Excel from the perspective of the UK National Health System over a lifetime horizon.  ...  Conclusion: The current allocation of treatment budget for CHC is not optimal in the UK.  ...  Constrained optimization modeling is a flexible tool to solve different decision problems based on a simple yet accurate framework.  ...

The eightfold way of deliberation dialogue

Peter McBurney, David Hitchcock, Simon Parsons
2006 International Journal of Intelligent Systems  
We further fully articulate the locutions and rules of a formal dialogue game for this model, so as to specify a protocol for deliberation dialogues.  ...  To assess our protocol we consider it against various records of human deliberations, against normative principles for the conduct of human dialogues, and with respect to the outcomes produced by dialogues  ...  If only two participants remain in a dialogue and one of these utters this locution, the dialogue terminates. Commitment Store Update: No effects.  ...

Tutui Viorel
2015 Argumentum: Journal of the Seminar of Discursive Logic, Argumentation Theory and Rhetoric  
After presenting these models I will provide a critical analysis of each one of them with the purpose of revealing their virtues and limits.  ...  In the concluding section, I will argue that any theoretical model is confronted with the "the paradox of democratic deliberatio [...]  ...  And the solution they support has to do with the provisional nature of the results of deliberation.  ...
