Discriminatory power of RNA family models
MOTIVATION RNA family models group nucleotide sequences that share a common biological function. These models can be used to find new sequences belonging to the same family. To succeed in this task, a model needs to exhibit high sensitivity as well as high specificity. As model construction is guided by a manual process, a number of problems can occur, such as the introduction of more than one ...
متن کاملThe Intrinsic Forensic Discriminatory Power of Diphthongs
This paper describes an experiment investigating how well same-speaker speech samples can be discriminated from different-speaker speech samples using acoustic parameters from Australian English diphthongs. A two-level kernel density multivariate likelihood ratio is used as a discriminant function on five of the diphthongs of the 171 speakers of the Bernard data base: /a /. Comparin...
متن کاملGroup discriminatory power of handwritten characters
Using handwritten characters we address two questions (i) what is the group identification performance of different alphabets (upper and lower case) and (ii) what are the best characters for the verification task (same writer/different writer discrimination) knowing demographic information about the writer such as age,sex or country of birth. The Bhattacharya distance is used to rank different ...
متن کاملDiscriminatory power of stoichiometry-driven protein folding?
There is a saying that when life hands you a lemon, you make lemonade out of it. I found that this has a parallel in molecular modeling: when your test of a putative diagnostic property fails to show discriminatory power, make an invariant out of it. The paper by Mittal, Jayaram, Shenoy and Bawa (1) is a brilliant example of this. Based on three independent observations, comparison of Cα distan...
متن کاملAssessing the Discriminatory Power of Biometric Verifiers
The task of establishing the distinctiveness of biometric data is important in many types of biometric applications. Earlier work had identified the concept of distance statistics as central to our approach to the individuality of a biometric, and the inferential statistical aspects had been considered crucial in evaluating the individuality of certain biometric data. Here we consider the geome...
