We show that, without any language model, Seq2Seq and RNN-Transducer models both outperfo...

Title: Phase Transitions of Spectral Initialization for High-Dimensional Nonconvex Estimation, Abstract: We study a spectral initialization method that serves a key role in recent work on estimating signals in nonconvex settings. Previous analysis of this method focuses on the phase retrieval problem and provides only ...

Title: Analysis of Footnote Chasing and Citation Searching in an Academic Search Engine, Abstract: In interactive information retrieval, researchers consider the user behavior towards systems and search tasks in order to adapt search results by analyzing their past interactions. In this paper, we analyze the user behav...

Title: Quantification of the memory effect of steady-state currents from interaction-induced transport in quantum systems, Abstract: Dynamics of a system in general depends on its initial state and how the system is driven, but in many-body systems the memory is usually averaged out during evolution. Here, interacting ...

Title: Quandle rings, Abstract: In this paper, a theory of quandle rings is proposed for quandles analogous to the classical theory of group rings for groups, and interconnections between quandles and associated quandle rings are explored.
