Fast and Efficient Local Search for Genetic Programming Based Loss Function Learning

1 code implementation1 Mar 2024 Christian Raymond, Qi Chen, Bing Xue, Mengjie Zhang

In this paper, we develop upon the topic of loss function learning, an emergent meta-learning paradigm that aims to learn loss functions that significantly improve the performance of the models trained under them.

Dialogue history integration into end-to-end signal-to-concept spoken language understanding systems

no code implementations14 Feb 2020 Natalia Tomashenko, Christian Raymond, Antoine Caubriere, Renato de Mori, Yannick Esteve

The dialog history is represented in the form of dialog history embedding vectors (so-called h-vectors) and is provided as an additional information to end-to-end SLU models in order to improve the system performance.

Generative Adversarial Networks for Multimodal Representation Learning in Video Hyperlinking

no code implementations15 May 2017 Vedran Vukotic, Christian Raymond, Guillaume Gravier

We show that GANs can be used for multimodal representation learning and that they provide multimodal representations that are superior to representations obtained with multimodal autoencoders.

One-Step Time-Dependent Future Video Frame Prediction with a Convolutional Encoder-Decoder Neural Network

no code implementations14 Feb 2017 Vedran Vukotić, Silvia-Laura Pintea, Christian Raymond, Guillaume Gravier, Jan van Gemert

There is an inherent need for autonomous cars, drones, and other robots to have a notion of how their environment behaves and to anticipate changes in the near future.
