Critiquing Art I agree with the workshop organizers that it is not constructive to evaluate interactive artwork under the same guidelines as traditional HCI work. There are often extremely divergent goals associated with artists and HCI researchers. Yes, there may be obvious parallels such as an artist that wants to insure that their work is correctly interpreted. However, art critique ≠ intera...

We show that, given a general mixed state for a quantum system, there are no physical means for broadcasting that state onto two separate quantum systems, even when the state need only be reproduced marginally on the separate systems. This result generalizes and extends the standard no-cloning theorem for pure states. 1995 PACS numbers: 03.65.Bz, 89.70.+c, 02.50.-r Typeset using REVTEX 1 The fl...

Correlations that violate a Bell inequality are said to be nonlocal; i.e., they do not admit a local and deterministic explanation. Great effort has been devoted to study how the amount of nonlocality (as measured by a Bell inequality violation) serves to quantify the amount of randomness present in observed correlations. In this work we reverse this research program and ask what do the randomn...

We address the problem of learning the parameters in graphical models when inference is intractable. A common strategy in this case is to replace the partition function with its Bethe approximation. We show that there exists a regime of empirical marginals where such Bethe learning will fail. By failure we mean that the empirical marginals cannot be recovered from the approximated maximum likel...

Sir, Saner and colleagues have made a good case for home haemodialysis (HHD) as an effective renal replacement therapy in Switzerland [1]. Yet, in the last paragraph of their case–cohort study of 58 patients, they admit that patient selection may have influenced their results. We agree. Our analysis of a much larger cohort, that of the United States Renal Data System, used the standardized mort...

In Dekel and Feinberg (2004) we suggested a test for discovering whether a potential expert is informed of the distribution of a stochastic process. This category test requires predicting a “small”– category I – set of outcomes. In this paper we show that under the continuum hypothesis there is a category test that cannot be manipulated, i.e. such that no matter how the potential expert randomi...
