Exploiting semi-supervised training through a dropout regularization in end-to-end speech recognition

In this paper, we explore various approaches for semi- supervised learning in an end-to-end automatic speech recog- nition (ASR) framework. The first step in our approach in- volves training a seed model on the limited amount of labelled data. Additional u ...

Island Interfaces: Insularity, Distance, and Proximity

Jérôme Chenal, Diego Alejandro Marcelo Mermoud

The main common point between insular territories is a limited amount of land. This might seem obvious or irrelevant because it concerns a large majority of states. However this ‘physical’ boundary defined by nature causes certain impacts: first of all a c ...

Uniqueness of equilibrium in a payment system with liquidation costs

Damir Filipovic, Léo Hamed Amini

We study a financial network where forced liquidations of an illiquid asset have a negative impact on its price, thus reinforcing network contagion. We give conditions for uniqueness of the clearing asset price and liability payments. Our main result holds ...
