On matching scores for LDA-based face
"... We address the problem of face verification using linear discriminant analysis and investigate the issue of matching score . We establish the reason behind the success of the normalised correlation. The improved understanding about the role of metric then naturally leads to a novel way of meas ..."

Combining Matching Scores in Identification Model
"... The paper discusses a problem of combination recognition scores for different classes produced by one recognizer during one recognition attempt. This problem arises in identification problems which we define as 1:N classification problems with big or variable N. Using artificial example we show that ..."

that intuitive solution of using solely best matching score is frequently suboptimal. Paper presents reasons for such behavior, and draws parallels with score normalization technique used in speaker identification. Two examples of real life applications illustrate the possible benefits of properly combining

Propensity Score Matching Methods For Non-Experimental Causal Studies
, 2002
"... This paper considers causal inference and sample selection bias in non-experimental settings in which: (i) few units in the non-experimental comparison group are comparable to the treatment units; and (ii) selecting a subset of comparison units similar to the treatment units is difficult because uni ..."

units must be compared across a high-dimensional set of pretreatment characteristics. We discuss the use of propensity score matching methods, and implement them using data from the NSW experiment. Following Lalonde (1986), we pair the experimental treated units with non-experimental comparison units
e Identification Model with Independent Matching Scores
"... Biometric applications can be divided into two types: verification tasks and identification tasks. For verification tasks a single matching score is given, and application accepts or rejects a matching attempt by thresholding the matching score. Based on the threshold value a performance characteris ..."

Methods and Statistics for Combining Motif Match Scores
- Journal of Computational Biology
, 1998
"... Position-specific scoring matrices are useful for representing and searching for protein sequence motifs. A sequence family can often be described by a group of one or more motifs, and an effective search must combine the scores for matching a sequence to each of the motifs in the group. We describe ..."

Privacy & Security Issues Related to Match Scores
"... Security and privacy issues remains a major hurdle in wide deployment of biometric based authentication system. For example, unauthorized access or regeneration of face templates has serious implications on the privacy of the concerned users. For robust and practical implementation of such system it ..."

it is necessary to identify and explore the possible ways by which reconstruction of template is feasible. In this paper, we show that even match scores carries sufficient information for reconstruction of the original face templates. We propose a novel non-iterative scheme to reconstruct face templates from
The Central Role of the Propensity Score in Observational Studies for Causal Effects.
- Biometrika
, 1983
"... SUMMARY The propensity score is the conditional probability of assignment to a particular treatment given a vector of observed covariates. Both large and small sample theory show that adjustment for the scalar propensity score is sufficient to remove bias due to all observed covariates. Application ..."

. Applications include: (i) matched sampling on the univariate propensity score, which is a generalization of discriminant matching, (ii) multivariate adjustment by subclassification on the propensity score where the same subclasses are used to estimate treatment effects for all outcome variables and in all
