Chebyshev approximations to the histogram χ2 kernel
The random Fourier embedding methodology can be used to approximate the performance of non-linear kernel classifiers in linear time on the number of training examples. However, there still exists a non-trivial performance gap between the approximation and the nonlinear models, especially for the exponential χ kernel, one of the most powerful models for histograms. Based on analogies with Chebys...
متن کاملConvexity of quantum χ2-divergence.
The general quantum χ(2)-divergence has recently been introduced by Temme et al. [Temme K, Kastoryano M, Ruskai M, Wolf M, Verstrate F (2010) J Math Phys 51:122201] and applied to quantum channels (quantum Markov processes). The quantum χ(2)-divergence is not unique, as opposed to the classical χ(2)-divergence, but depends on the choice of quantum statistics. It was noticed that the elements in...
متن کاملSome Comments on χ2 Minimisation Applications
χ2 minimisation. The determination of parameters in fits to measured data is a standard task of data analysis. The standard method of least squares is often referred to as χ2 minimisation, which is a confusion in terminology; the minimum of the least squares sum follows often, but not always, the χ2 distribution. In “χ2 minimization” used in a wide range of applications from calorimeter calibra...
متن کاملCriticality in the configuration-mixed Interacting Boson Model: (2) Q̂(χ1)Q̂(χ1)-Q̂(χ2)Q̂(χ2) mixing
The case of Q̂(χ1) · Q̂(χ1)-Q̂(χ2) · Q̂(χ2) mixing in the interacting boson model is studied within its mean-field approximation. It is shown that the criticality conditions lead to two classes of solutions and that χ1 and χ2 need to have an opposite sign to allow for prolate-oblate shape coexistence. No evidence for a stable triaxial minimum is found. Phase diagrams for selected cases have been co...
متن کاملA New Approach to χ2 Cryptanalysis of Block Ciphers
The main contribution of this paper is a new approach to χ analyses of block ciphers in which plaintexts are chosen in a manner similar to that in a square/saturation attack. The consequence is a faster detection of χ correlation when compared to conventional χ cryptanalysis. Using this technique we (i) improve the previously best-known χ attacks on 2and 4-round RC6, and (ii) mount the first at...
