BACKGROUND Decision curve analysis (DCA) has been proposed as an alternative method for evaluation of diagnostic tests, prediction models, and molecular markers. However, DCA is based on expected utility theory, which has been routinely violated by decision makers. Decision-making is governed by intuition (system 1), and analytical, deliberative process (system 2), thus, rational decision-makin...

In 4 studies, the authors demonstrated that when errors associated with action were inconsistent with decision nakers' orientation, they were undesirable and produced more regret than did errors associated with inaction. Conversely, when errors associated with action were consistent with decision makers' orientation. they were desirable and produced less regret than did errors associated with i...

Purpose – The purpose of this paper is to assess how regret affects consumer satisfaction levels, extent of rumination, and brand-switching intention. The paper also seeks to examine any mediating effects between regret and rumination that can be found due to consumers’ negative emotions. Design/methodology/approach – A purchase-decision scenario was presented to 125 undergraduate students. A b...

We consider a policy gradient algorithm applied to finite-arm bandit problem with Bernoulli rewards. allow learning rates depend on the current state of rather than using deterministic time-decreasing rate. The forms Markov chain probability simplex. apply Foster–Lyapunov techniques analyze stability this chain. prove that, if are well-chosen, then is transient chain, and converges optimal arm ...

RELATIONSHIP DECISION-MAKING AS A MEDIATOR BETWEEN REGRET, AUTONOMY, AND TWO FORMS OF RELATIONSHIP COMMITMENT: DEDICATION AND CONSTRAINT Ashley M. A. Fehr Old Dominion University, 2015 Director: Dr. James M. Henson This study examined the relationships among autonomy, anticipated regret, decision-making, and dedication and constraint commitment of college students in romantic relationships. Two...

We present two alternative ways to apply PAC-Bayesian analysis to sequences of dependent random variables. The first is based on a new lemma that enables to bound expectations of convex functions of certain dependent random variables by expectations of the same functions of independent Bernoulli random variables. This lemma provides an alternative tool to Hoeffding-Azuma inequality to bound con...

This paper explores a fundamental connection between computational learning theory and game theory through a property we call no-Φ-regret. Given a set of transformations Φ (i.e., mappings from actions to actions), a learning algorithm is said to exhibit no Φ-regret if an agent experiences no regret for playing the actions the algorithm prescribes, rather than playing the transformed actions pre...
