Log AdaBoost: Optimizing Polylog loss function to improve the generalization performance of AdaBoost

Youth Academic Annual Conference of Chinese Association of Automation, 2022
As an ensemble learning algorithm, the classic AdaBoost has achieved incredible success in both classification and regression problems, but its generalization ability is still unsatisfactory. A modified version of the Real AdaBoost which is called Gentle

A new generalization of logistic Weibull distribution with theory and practical illustration

Journal of Statistics & Management Systems, 2021
This study developed the exponentiated logistic Weibull distribution as a new generality of the logistic Weibull distribution to deal with real-life data sets.

On exponential sums for coefficients of general L-functions

International Journal of Number Theory, 2021
We investigate the order of exponential sums involving the coefficients of general [Formula: see text]-functions satisfying a suitable functional equation and give some new estimates, including refining certain results in preceding works [X. Ren and Y.

Time-Independent Information-Theoretic Generalization Bounds for SGLD

Neural Information Processing Systems, 2023
We provide novel information-theoretic generalization bounds for stochastic gradient Langevin dynamics (SGLD) under the assumptions of smoothness and dissipativity, which are widely used in sampling and non-convex optimization studies.

Generalization of cyclic refinements of Jensen inequality by montgomery identity and Green’s function

Asian-European Journal of Mathematics, 2017
We consider discrete and continuous cyclic refinements of Jensen’s inequality and generalize them from convex function to higher order convex function by means of Lagrange Green’s function and Montgomery identity.

Estimation of the generalized exponential renewal function

Journal of Statistical Computation and Simulation, 2013
When the shape parameter is a non-integer of the generalized exponential (GE) distribution, the analytical renewal function (RF) usually is not tractable. To overcome this, the approximation method has been used in this paper. In the proposed model, the n-fold convolution of the GE cumulative distribution function (CDF) is approximated by n-fold ...

GENERATING FUNCTIONS OF EXPONENTIAL TYPE FOR ORTHOGONAL POLYNOMIALS

Infinite Dimensional Analysis, Quantum Probability and Related Topics, 2004
Let \(\{ P_n : n\in N_0, \deg P_n=n\}\) be a sequence of monic orthogonal polynomials for a given probability measure on \((-\infty, \infty)\). A function \(\psi(x, t)\) is a generating function of the polynomials \(P_n\) if \[ \psi(t,x)=\sum_{n=0}^\infty a_n t^n P_n(x). \] The following result is proved.

On the evaluation of generalized exponential integral functions

Journal of Quantitative Spectroscopy and Radiative Transfer, 2006
This paper deals with generalized exponential integral (GEI) functions arising in the study of anisotropic scattering in a multidimensional media. These functions are represented as finite linear combinations of basic GEIs introduced in this work. The recurrence relations are derived for the linear combination coefficients and basic GEIs.
