Conditioned Query Generation for Task-Oriented Dialogue Systems

1 code implementation9 Nov 2019 Stéphane d'Ascoli, Alice Coucke, Francesco Caltagirone, Alexandre Caulier, Marc Lelarge

Scarcity of training data for task-oriented dialogue systems is a well known problem that is usually tackled with costly and time-consuming manual data annotation.

A Deterministic and Generalized Framework for Unsupervised Learning with Restricted Boltzmann Machines

no code implementations10 Feb 2017 Eric W. Tramel, Marylou Gabrié, Andre Manoel, Francesco Caltagirone, Florent Krzakala

Restricted Boltzmann machines (RBMs) are energy-based neural-networks which are commonly used as the building blocks for deep architectures neural architectures.

Inferring Sparsity: Compressed Sensing using Generalized Restricted Boltzmann Machines

no code implementations13 Jun 2016 Eric W. Tramel, Andre Manoel, Francesco Caltagirone, Marylou Gabrié, Florent Krzakala

In this work, we consider compressed sensing reconstruction from $M$ measurements of $K$-sparse structured signals which do not possess a writable correlation model.

Blind Calibration in Compressed Sensing using Message Passing Algorithms

no code implementations NeurIPS 2013 Christophe Schulke, Francesco Caltagirone, Florent Krzakala, Lenka Zdeborová

We study numerically the phase diagram of the blind calibration problem, and show that even in cases where convex relaxation is possible, our algorithm requires a smaller number of measurements and/or signals in order to perform well.
