Importance-based Multimodal Autoencoder

no code implementations1 Jan 2021 Sayan Ghosh, Eugene Laksana, Louis-Philippe Morency, Stefan Scherer

In this paper we propose the IMA (Importance-based Multimodal Autoencoder) model, a scalable model that learns modality importances and robust multimodal representations through a novel cross-covariance based loss function.

Improving Recurrent Neural Network Responsiveness to Acute Clinical Events

no code implementations28 Jul 2020 David Ledbetter, Eugene Laksana, Melissa Aczon, Randall Wetzel

This work presents input data perseveration as a method of training and deploying an RNN model to make its predictions more responsive to newly acquired information: input data is replicated during training and deployment.

The Impact of Extraneous Variables on the Performance of Recurrent Neural Network Models in Clinical Tasks

no code implementations1 Apr 2019 Eugene Laksana, Melissa Aczon, Long Ho, Cameron Carlin, David Ledbetter, Randall Wetzel

Electronic Medical Records (EMR) are a rich source of patient information, including measurements reflecting physiologic signs and administered therapies.

Learning Representations of Affect from Speech

no code implementations15 Nov 2015 Sayan Ghosh, Eugene Laksana, Louis-Philippe Morency, Stefan Scherer

Experiments on a well-established real-life speech dataset (IEMOCAP) show that the learnt representations are comparable to state of the art feature extractors (such as voice quality features and MFCCs) and are competitive with state-of-the-art approaches at emotion and dimensional affect recognition.
