Daylight savings: what an answer to the perceptual variation problem cannot be

Simulating what cannot be simulated

The background to these notes is the expectation that mathematical modelling and simulation is going to play increasingly important role in the understanding of the organization and control of genetic-, metabolic-, and signalling pathways. I am going to argue that for modelling and simulation to help our understanding of cellular dynamics, the current practice of experimental design has to chan...

What Cannot be Learned with Bethe Approximations

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...

What seems to be the problem?

Psychotherapy has lost some of its stigma since Sept. 11, but many Americans still have issues with seeing a shrink.

swinburne’s answer to the problem of evil

the examination and explanation of swinburne’s view about the “problem of evil” and his response to it, is the main approach of this paper. in his viewpoint, in contrast with this idea, we should appeal to “theory of theodicy”. his understanding of theodicy depends on “the greater goods” and according to which evils are necessary for attaining greater goods. moreover, in this paper we'll t...
