Auxiliary Variables in Conditional Gaus Speech Recogni

In previous work, we presented a case study using an estimated pitch value as the conditioning variable in conditional Gaussians that showed the utility of hiding the pitch values in certain situations or in modeling it independently of the hidden state in others. Since only single conditional Gaussians were used in that work, we extend that work here to using conditional Gaussian mixtures in t...

Neyman-Pearson Detection of Gaus Closed-Form Error Expone

The performance of Neyman-Pearson detection of correlated stochastic signals using noisy observations is investigated via the error exponent for the miss probability with a fixed level. Using the statespace structure of the signal and observation model, a closed-form expression for the error exponent is derived, and the connection between the asymptotic behavior of the optimal detector and that...

A Hierarchy of Armchairs: Gerald Gaus on Political Thought Experiments

Th e paper places the work of G. Gaus into the tradition of political thought experimenting. In particular, his strategy of modeling moral decision by the heuristic device of idealized Members of the Public is presented as an iterated thought experiment, which stands in marked contrast with more traditional devices like the veil of ignorance. Th e consequences are drawn, and issues of utopianis...

The Tragedy of Exclusion Katharina Pistor & Sai Balakrishnan

The tragedy of exclusion represents a state of the world where individual and entire social groups are excluded from access to resources, goods or services that are essential for their survival, such as water, food and shelter. There is broad normative consensus that all humans should have access to essential resources irrespective of wealth, power or status, but this normative goal is far from...
