Hybrid Clustering based on Content and Connection Structure using Joint Nonnegative Matrix Factorization | We present a hybrid method for latent information discovery on the data sets

Embedding dimension and codimension of tensor products of algebras over a field | Let k be a field. This paper investigates the embedding dimension and
codimension of Noetherian local rings arising as localizations of tensor

Improved nonparametric estimation of the drift in diffusion processes | In this paper, we consider the robust adaptive non parametric estimation
problem for the drift coefficient in diffusion processes. An adaptive model

Quasar Rain: the Broad Emission Line Region as Condensations in the Warm Accretion Disk Wind | The origin of the broad emission line region (BELR) in quasars and active

Consistent polynomial-time unseeded graph matching for Lipschitz graphons | We propose a consistent polynomial-time method for the unseeded node matching

Photoinduced filling of near nodal gap in Bi$_2$Sr$_2$CaCu$_2$O$_{8+δ}$ | We report time and angle resolved spectroscopic measurements in optimally

Globally convergent Jacobi-type algorithms for simultaneous orthogonal symmetric tensor diagonalization | In this paper, we consider a family of Jacobi-type algorithms for

Representing the Deligne-Hinich-Getzler $\infty$-groupoid | The goal of the present paper is to introduce a smaller, but equivalent
version of the Deligne-Hinich-Getzler $\infty$-groupoid associated to a
homotopy Lie algebra. In the case of differential graded Lie algebras, we
represent it by a universal cosimplicial object.

Sentence-level quality estimation by predicting HTER as a multi-component metric | This submission investigates alternative machine learning models for
predicting the HTER score on the sentence level. Instead of directly predicting
the HTER score, we suggest a model that jointly predicts the amount of the 4
distinct post-editing operations, which are then used to calculate the HTER
score. This also... | 1 | 0 | 0 | 0 | 0 | 0 |
Machine Assisted Analysis of Vowel Length Contrasts in Wolof | Growing digital archives and improving algorithms for automatic analysis of
