The awe and mystery of t-norm

چکیده
A popular score normalization technique termed T-norm is the central focus of this paper. Based on widely confirmed experimental observation regarding T-norm tilting the DET curves of speaker detection systems, we set out to identify the components taking role in this phenomenon. We claim that under certain local assumptions the T-norm performs a gaussianization of the individual true and impostor score populations and further derive conditions for clockwise and counter-clockwise DET rotations caused by this transform.

متن کاملHESITANT FUZZY INFORMATION MEASURES DERIVED FROM T-NORMS AND S-NORMS
In this contribution, we first introduce the concept of metrical T-norm-based similarity measure for hesitant fuzzy sets (HFSs) {by using the concept of T-norm-based distance measure}. Then,the relationship of the proposed {metrical T-norm-based} similarity {measures} with the {other kind of information measure, called the metrical T-norm-based} entropy measure {is} discussed. The main feature ...

Two hundred and forty (240) farmers were sampled by a multi stage sampling procedure and used as respondents for the study. Well-structured questionnaires were used for data collection. The main means of data analysis were percentages and correlation. Findings revealed that 4...
متن کاملA NORM INEQUALITY FOR CHEBYSHEV CENTRES
In this paper, we study the Chebyshev centres of bounded subsets of normed spaces and obtain a norm inequality for relative centres. In particular, we prove that if T is a remotal subset of an inner product space H, and F is a star-shaped set at a relative Chebyshev centre c of T with respect to F, then llx - qT (x)1I2 2 Ilx-cll2 + Ilc-qT (c) 112 x E F, where qT : F + T is any choice functi...
