Regret as Autobiographical Memory
… memory framework for the study of regret is contrasted with traditional decision-making approaches to regret. Based on the autobiographical memory framework a memory-based distinction is introduced between regrets for specific and general events. Across 6 studies the distinction is …

Collaborative filtering with low regret
… following item-item paradigm achieves a regret (which captures the number of poor recommendations over T time steps) that is sublinear and scales as ... , where d is the doubling dimension of the item space. As the second main result we show that the cold-start time (which is the first …

Optative Regret in George Eliot's Middlemarch
… fiction, there exists the concept of optative regret,which is when a character becomes aware of and yearns for alternate versions of him orherself that may have become realized if different choices had been made in his or herpast. George Eliot's Middlemarch constantly confronts the reader with …

Children’s thinking about regret and relief
… children’s thinking about their own and others’ regret and relief. The results were described in relation to the developmental counterfactual thinking literature which offers an account of gradual improvements in order to achieve adult-like counterfactual thinking. Children aged 5 to 6 years old …

No-Regret Learning in General Games
This thesis investigates the regret performance of no-regret learning algorithms in the competitive, though not fully-adversarial, environment of games. We establish exponential improvements on previously best-known external and internal regret bounds for these settings. We show that Optimistic …

The Ontogenesis of Counterfactual Emotions: Regret and Relief
… deals with the development of the emotions of regret and relief. Five studies were conducted to determine at which age children start to understand, to feel and to attribute to others counterfactual emotions, as well as to experience the comparison with others during a choice. Study 1 aims to …

Interpersonal regret and prosocial risk taking in children
… various counterfactual emotions, one of which - regret- has received particular research attention. Regret is the emotion we feel when things would have turned out better than they are now, if only we had acted differently in some way. Thus, regret involves a comparison between reality and a …

Exploring Factors Associated with Regret Following Cancer Treatment
… decision may lead to later decisional regret, which has been linked to a lower quality of life in survivors. While some research has begun to explore the factors that influence decisional regret, few studies have comprehensively examined the role that psychological and social factors …

The Influence of Risk and Regret on Marketing Exchanges
… this way leads, logically, to the development of regret, defined as the expectation of loss from not proceeding with an exchange. The two constructs are not viewed as mirror images and this was substantiated by the data.

Passivity, no-regret, and performance in online learning and games
… investigates the interplay between passivity, no-regret and performance of continuous-time learning dynamics. The analysis is divided into two parts: (i) the interaction between a learning model and a dynamic, uncertain environment, and (ii) the interaction among multiple adaptive learners within …

REGRET AS A MODULATORY SYSTEM: HOW IMAGINED FUTURES BECOME REAL PASTS
… through anticipated and retrospective regret. Using a longitudinal design, we measured students’ study habit quality, study habit quantity, study goals, anticipated regret, retrospective regret, and behavior-goal inconsistency. From this, we proposed four specific hypotheses: (a) …

Consistency-Fit and the Impact of Self-Awareness on Retrospective Regret
… to further explore the nature and experience of regret, and to supplement previous findings from the consistency-fit model of regret (Seta, McElroy, & Seta, 2001; Seta, Seta, McElroy, & Hatz, 2008) with assumptions and findings from the area of self-awareness research. The primary hypothesis was …

Hurting to Helping: Regret as a Potential Motivator of Helping Behavior
… analyses of a previous study indicated that regret may also motivate increased prosocial intentions, but no research has been published to experimentally test whether feelings of regret may motivate prosocial behaviors. Therefore, the present research seeks to experimentally manipulate …

Improved worst-case regret bounds for randomized least-squares value iteration
This work studies regret minimization with randomized value functions in reinforcement learning. In tabular finite-horizon Markov Decision Processes, we introduce a clipping variant of one classical Thompson Sampling (TS)-like algorithm, randomized least-squares value iteration (RLSVI). Our …

Low-complexity, low-regret link rate selection in rapidly varying wireless channels
… states and which achieves at most logarithmic regret as a function of time when compared to an optimal algorithm which knows the probability distribution of the channel states.

Exposure to sexual media and college students' sexual risk-taking and sexual regret
… sexual media exposure may be linked to sexual regret indirectly through its effect on sexual risk-taking. The main project was an online survey completed by 561college students. To assist the investigation, three subprojects were conducted beforehand. Subproject 1 employed focus group …

A methodology for the robustness-based evaluation of systems-of-systems alternatives using regret analysis
… is defined as the integral of the alternative s regret over the likelihood-weighted plausible scenario space. Surrogate modeling techniques were used to overcome shortcomings associated with conventional regret analysis, including the discrete nature of scenario cases and static results. The new …

How different types of anticipated regret advertising messages interact with mood to influence purchase intention
… can influence people’s choice. To avoid feeling regretful, consumers generally change their original decision or attitude to ensure that a future outcome is congruent with their expectation. The effect of anticipated regret has been applied in health and safety domains for years. However, only a …
