TLDR
By using real data coming from a person authentication system using image and speech data, it is confirmed that the proposed supervisor improves the quality of individual expert decisions by reaching success rates of 99.5 %.Abstract:
We present an algorithm functioning as a supervisor module in a multi expert decision making machine. It uses the Bayes theory in order to estimate the biases of individual expert opinions. These are then used to calibrate and conciliate expert opinions to one opinion. We present a framework for simulating decision strategies using expert opinions whose properties are easily modifiable. By using real data coming from a person authentication system using image and speech data we were able to confirm that the proposed supervisor improves the quality of individual expert decisions by reaching success rates of 99.5 %.read more

Score normalization in multimodal biometric systems
TL;DR: Study of the performance of different normalization techniques and fusion rules in the context of a multimodal biometric system based on the face, fingerprint and hand-geometry traits of a user found that the application of min-max, z-score, and tanh normalization schemes followed by a simple sum of scores fusion method results in better recognition performance compared to other methods.

Filterbank-based fingerprint matching
TL;DR: A filter-based fingerprint matching algorithm which uses a bank of Gabor filters to capture both local and global details in a fingerprint as a compact fixed length FingerCode and is able to achieve a verification accuracy which is only marginally inferior to the best results of minutiae-based algorithms published in the open literature.

Combining Probability Distributions from Dependent Information Sources
TL;DR: In the face of uncertainty, all available information should be used to make inferences or decisions as mentioned in this paper, when probability distributions for an uncertain quantity are obtained from experts, models, or models.

On the Reconciliation of Probability Assessments
TL;DR: In this paper, a general model for the analysis of probability assessments is introduced, and two approaches to reconcile incoherent probability assessments are developed, one internal approach, one estimates the subject's true probabilities on the basis of his assessments, and another external observer updates his own coherent probabilities in the light of the assessments made by the subject.

Reliability (and Fault Tree) Analysis Using Expert Opinions
TL;DR: A formal procedure for the use of expert opinions in reliability (and fault tree) analysis in the case of multicomponent parallel redundant systems for which there could be a single expert or a group of experts giving us opinions about each component.
