Hyperparameter Choice as Search Bias in AlphaZero

ABSTRACT We investigate the effect of regulatory requirements on impairment decisions and managers' search for and evaluation of impairment information. We manipulate reversibility of impairment losses (“can be reversed” versus “cannot be reversed”) and transparency in disclosures of impairment assumptions (more transparent versus less transparent) in a 2 × 2 experiment. We find that managers are more willing to impair when impairment losses can be reversed than when they cannot be reversed, but this effect does not vary with disclosure transparency. We also find that managers display information search bias in all four experimental conditions, however, regulatory requirements do not result in differences in the level of information search bias across the conditions. In contrast, regulatory requirements affect the differences in the level of information evaluation bias across conditions. We find that when impairment losses cannot be reversed, information evaluation bias is higher when disclosures are more transparent than less transparent. JEL Classification: M40; M41.

Agenda Manipulation

Empirical studies suggest that mission-oriented bureaucrats bias their design of program alternatives to increase the odds that a superior will choose the kind of program the officials want. However, political executives may anticipate this manipulation and try to reassert control. These struggles are examined in three models. In Model 1 a senior bureaucrat is interested only in missions; the bureaucrat's political superior controls him or her by rejecting inferior proposals and entertaining new options from other policy specialists. Model 2 is a principal-agent analysis. Here the official is interested only in budgets; the official's superior reduces search bias by creating an ex ante incentive scheme. In Model 3 the bureaucrat cares about both budgets and programs; the superior uses both his or her final review authority and ex ante incentives to reduce agenda manipulation. The models' contrasting implications for the political control of bureaucracy are examined.

Search Bias

O mundo contemporâneo é caracterizado por um amplo volume de informações produzidas. Contudo, proceder a seleção e leitura dessas informações por meio de relatos de pesquisa ou de notícias ainda é um desafio. Entre os obstáculos presentes se destacam os vieses da informação, originados por tratamentos de jornalistas ou pesquisadores, ou mesmo provocados intencionalmente para subverter a representação da realidade a partir dos dados obtidos. Assim, o presente estudo visa discutir a interpretação de informações visuais em representações gráficas de cálculos estatísticos de modo a contextualizar alguns dos principais recursos visuais de enviesamento de pesquisa. Para tanto, aborda os principais modos de enviesamento em pesquisas a partir das representações da estatística e da visualização de dados e identifica alguns passos nos quais o enviesamento se traduz em informações visuais. A partir do levantamento realizado, sugere-se que a compreensão visual dos recursos de visualização de dados pode ao menos instigar a indagação do leitor acerca do possível viés.*****The contemporary world is characterized by a large volume of produced information. However, selecting and reading this information through research reports or news is still a challenge. Among the present obstacles stand out the information bias, originated by treatments of journalists or researchers, or even intentionally provoked to subvert the representation of reality from the obtained data. Thus, the present study aims to discuss the interpretation of visual information in graphical representations of statistical calculations in order to contextualize some of the main visual bias features of research. To this end, it addresses the main modes of search bias from statistical representations and data visualization and identifies some steps in which bias translates into visual information. From the study, it is suggested that the visual understanding of data visualization resources may at least instigate the reader's question about the possible bias.

Search Bias

We report a rare case of concurrent calcaneonavicular osseous coalition and osteoid osteoma of the navicular. While each pathology is relatively common, the combination of the two in one foot is rare and as such can present a unique challenge to imaging interpretation. This case reinforces the importance of the concept of “satisfaction of search.”
