• Abstract: Possibility and probability theories are alternative and complementary ways to deal with uncertainty, which has motivated over the last years an interest for the study of ways to transform probability distributions into possibility distributions and conversely. This paper studies the advantages and shortcomings of two well-known discrete probability to possibility transformations: the optimal transformation and the symmetrical transformation, and presents a novel parametric family of probability to possibility transformations which generalizes them and alleviate their shortcomings, showing a big potential for practical application. The paper also introduces a novel fuzzy measure of specificity for probability distributions based on the concept of fuzzy subsethood and presents a empirical validation of the generalized transformation usefulness applying it to the text authorship attribution problem.

• Probabilistic Coherence Transformation [0.0]
  We investigate the probabilistic coherence transformation under strictly incoherent operations. It is found that the large coherence gain can be realized with the price of success probability loss. As an application, it is shown that the conversion from coherence into entanglement may benefit from probabilistic coherence transformation.

We demonstrate that the interchangeability principle holds if and only if certain measurable projection and weak measurable selection conditions are satisfied.

We propose a novel combination of optimization and sampling techniques for approximate Bayesian inference.

  We study few-shot supervised domain adaptation (DA) for regression problems, where only a few labeled target domain data and many labeled source domain data are available. Many of the current DA methods base their transfer assumptions on either parametrized distribution shift or apparent distribution similarities. We propose mechanism transfer, a meta-distributional scenario in which a data generating mechanism is invariant among domains.
