Bias Reduction in Sample-Based Optimization [PDF]

open access: yesSIAM Journal on Optimization, 2022
We consider stochastic optimization problems which use observed data to estimate essential characteristics of the random quantities involved. Sample average approximation (SAA) or empirical (plug-in) estimation are very popular ways to use data in optimization. It is well known that sample average optimization suffers from downward bias.

Comparing personal and social optimism biases: magnitude, overlap, modifiability, and links with social identification and expertise

open access: yesHumanities & Social Sciences Communications, 2021
Individuals are more optimistic about their own future than a comparable person’s future (personal optimism bias). In addition, they show overoptimism toward people or social groups they identify with compared with those they do not identify with (social

Bias of Particle Approximations to Optimal Filter Derivative [PDF]

open access: yesSIAM Journal on Control and Optimization, 2021
In many applications, a state-space model depends on a parameter which needs to be inferred from a data set. Quite often, it is necessary to perform the parameter inference online. In the maximum likelihood approach, this can be done using stochastic gradient search and the optimal filter derivative.

The optimism bias [PDF]

open access: yesCurrent Biology, 2011
SummaryThe ability to anticipate is a hallmark of cognition. Inferences about what will occur in the future are critical to decision making, enabling us to prepare our actions so as to avoid harm and gain reward. Given the importance of these future projections, one might expect the brain to possess accurate, unbiased foresight.

Optimality bias in moral judgment

open access: yesJournal of Experimental Social Psychology, 2017
We often make decisions with incomplete knowledge of their consequences. Might people nonetheless expect others to make optimal choices, despite this ignorance? Here, we show that people are sensitive to moral optimality: that people hold moral agents accountable depending on whether they make optimal choices, even when there is no way that the agent ...

Relationships Between Self-Rated Health at Three Time Points: Past, Present, Future

open access: yesFrontiers in Psychology, 2022
Background: Multiple studies have shown that people who have experienced a serious health problem such as an injury tend to overrate the quality of health they had before that event.
