Cover Story: An approximate 2-decomposable rigid-backbone sequence energy landscape (top) is superimposed over the true sequence energy landscape (bottom). While the two landscapes share a lot, the GMEC in the top landscape corresponds to a shallow basin in the more complex real energy landscape. By enumerating diverse low-energy solutions in the approximate landscape (blacks dots surrounded by circles denoting distance constraints), a third solution emerges in a shallow basin which almost matches the GMEC of the true landscape.

Unbiased Fuzzy Estimators in Fuzzy Hypothesis Testing

  • Nikos Mylonas and
  • Basil Papadopoulos

17 June 2021

In this paper, we develop fuzzy, possibilistic hypothesis tests for testing crisp hypotheses for a distribution parameter from crisp data. In these tests, fuzzy statistics are used, which are produced by the possibility distribution of the estimated...
