Fast Learning of MNL Model from General Partial Rankings with Application to Network Formation Modeling [PDF]
Web Search and Data Mining, 2021 Multinomial Logit (MNL) is one of the most popular discrete choice models and has been widely used to model ranking data. However, there is a long-standing technical challenge of learning MNL from many real-world ranking data: exact calculation of the ...

Non-singular spherical harmonic expressions of geomagnetic vector and gradient tensor fields in the local north-oriented reference frame [PDF]
Geoscientific Model Development, 2015 General expressions of magnetic vector (MV) and magnetic gradient tensor (MGT) in terms of the first- and second-order derivatives of spherical harmonics at different degrees/orders are relatively complicated and singular at the poles. In this paper, we

Homotopy-Sumudu transforms for solving system of fractional partial differential equations
Advances in Difference Equations, 2020 In this paper, we investigate the Sumudu transforms and homotopy analysis method (S-HAM) for solving a system of fractional partial differential equations. A general framework for solving such a kind of problems is presented.

Poset structures in Boij-S\"oderberg theory [PDF]
, 2011 Boij-S\"oderberg theory is the study of two cones: the cone of cohomology tables of coherent sheaves over projective space and the cone of standard graded minimal free resolutions over a polynomial ring.
