Overcoming Copyright Barriers in Corpus Distribution Through Non-Reversible Hashing
Arthur Amalvy, Vincent Labatut, Xavier Bost +1
While annotated corpora are crucial in the field of natural language processing (NLP), those containing copyrighted material are difficult to exchange among researchers. Yet, such…
Improved optimization strategies for deep Multi-Task Networks
Lucas Pascal, Pietro Michiardi, Xavier Bost +2
In Multi-Task Learning (MTL), it is a common practice to train multi-task networks by optimizing an objective function, which is a weighted average of the task-specific objective f…
Maximum Roaming Multi-Task Learning
Lucas Pascal, Pietro Michiardi, Xavier Bost +2
Multi-task learning has gained popularity due to the advantages it provides with respect to resource usage and performance. Nonetheless, the joint optimization of parameters with r…
Serial Speakers: a Dataset of TV Series
Xavier Bost, Vincent Labatut, Georges Linares
For over a decade, TV series have been drawing increasing interest, both from the audience and from various academic fields. But while most viewers are hooked on the continuous plo…
Semantic and Visual Similarities for Efficient Knowledge Transfer in CNN Training
Lucas Pascal, Xavier Bost, Benoît Huet
In recent years, representation learning approaches have disrupted many multimedia computing tasks. Among those approaches, deep convolutional neural networks (CNNs) have notably r…
Remembering Winter Was Coming: Character-Oriented Video Summaries of TV Series
Xavier Bost, Serigne Gueye, Vincent Labatut +4
Today's popular TV series tend to develop continuous, complex plots spanning several seasons, but are often viewed in controlled and discontinuous conditions. Consequently, most vi…
Extraction and Analysis of Fictional Character Networks: A Survey
Vincent Labatut, Xavier Bost
A character network is a graph extracted from a narrative, in which vertices represent characters and edges correspond to interactions between them. A number of narrative-related p…
M2H-GAN: A GAN-based Mapping from Machine to Human Transcripts for Speech Understanding
Titouan Parcollet, Mohamed Morchid, Xavier Bost +1
Deep learning is at the core of recent spoken language understanding (SLU) related tasks. More precisely, deep neural networks (DNNs) drastically increased the performances of SLU…
Multiple topic identification in telephone conversations
Xavier Bost, Marc El Bèze, Renato De Mori
This paper deals with the automatic analysis of conversations between a customer and an agent in a call centre of a customer care service. The purpose of the analysis is to hypothe…
Constrained speaker diarization of TV series based on visual patterns
Xavier Bost, Georges Linares
Speaker diarization, usually denoted as the ''who spoke when'' task, turns out to be particularly challenging when applied to fictional films, where many characters talk in various…
Multiple topic identification in human/human conversations
X. Bost, G. Senay, M. El-Bèze +1
The paper deals with the automatic analysis of real-life telephone conversations between an agent and a customer of a customer care service (ccs). The application domain is the pub…
Audiovisual speaker diarization of TV series
Xavier Bost, Georges Linarès, Serigne Gueye
Speaker diarization may be difficult to achieve when applied to narrative films, where speakers usually talk in adverse acoustic conditions: background music, sound effects, wide v…
Extraction and Analysis of Dynamic Conversational Networks from TV Series
Xavier Bost, Vincent Labatut, Serigne Gueye +1
Identifying and characterizing the dynamics of modern tv series subplots is an open problem. One way is to study the underlying social network of interactions between the character…
Narrative Smoothing: Dynamic Conversational Network for the Analysis of TV Series Plots
Xavier Bost, Vincent Labatut, Serigne Gueye +1
Modern popular TV series often develop complex storylines spanning several seasons, but are usually watched in quite a discontinuous way. As a result, the viewer generally needs a…
How to merge three different methods for information filtering ?
Jean-Valère Cossu, Ludovic Bonnefoy, Xavier Bost +1
Twitter is now a gold marketing tool for entities concerned with online reputation. To automatically monitor online reputation of entities , systems have to deal with ambiguous ent…
