Discarding Logic

Discarding logic: 2008 Ancel Keys Memorial Lecture.

T hank you. The comments I am about to make are my own personal views. They are not the views of the National Heart, Lung, and Blood Institute or the US Department of Health and Human Services. I have no conflicts of interest to disclose. There once was a king who had 2 servants. 1 One day, he asked the servants to take buckets down to the well, which was located just outside the palace. He tol...

Measuring Instability in Normal Residuated Logic Programs: Discarding Information

Inconsistency in the framework of general residuated logic programs can be, somehow, decomposed in two notions: incoherence and instability. In this work, we focus on the measure of instability of normal residuated programs. Some measures are provided and initial results are obtained in terms of the amount of information that have to be discarded in order to recover stability.

Better models by discarding data?

In macromolecular X-ray crystallography, typical data sets have substantial multiplicity. This can be used to calculate the consistency of repeated measurements and thereby assess data quality. Recently, the properties of a correlation coefficient, CC1/2, that can be used for this purpose were characterized and it was shown that CC1/2 has superior properties compared with `merging' R values. A ...

Discarding data may help in system identification

We present results concerning the parameter estimates obtained by prediction error methods in the case of input signals that are insuuciently rich. Such input signals are typical of industrial measurements where occasional stepwise reference changes occur. As is intuitively obvious, the data located around the input signal discontinuities carry most of the useful information. Using singular val...
