Accelerating Look-ahead in Bayesian Optimization: Multilevel Monte Carlo is All you Need

1 code implementation3 Feb 2024 Shangda Yang, Vitaly Zankin, Maximilian Balandat, Stefan Scherer, Kevin Carlberg, Neil Walton, Kody J. H. Law

We leverage multilevel Monte Carlo (MLMC) to improve the performance of multi-step look-ahead Bayesian optimization (BO) methods that involve nested expectations and maximizations.

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.

What type of happiness are you looking for? - A closer look at detecting mental health from language

no code implementations WS 2018 Alina Arseniev-Koehler, Sharon Mozgai, Stefan Scherer

Computational models to detect mental illnesses from text and speech could enhance our understanding of mental health while offering opportunities for early detection and intervention.

A Cross-modal Review of Indicators for Depression Detection Systems

no code implementations WS 2017 Michelle Morales, Stefan Scherer, Rivka Levitan

Automatic detection of depression has attracted increasing attention from researchers in psychology, computer science, linguistics, and related disciplines.

Learning Representations of Emotional Speech with Deep Convolutional Generative Adversarial Networks

no code implementations22 Apr 2017 Jonathan Chang, Stefan Scherer

Automatically assessing emotional valence in human speech has historically been a difficult task for machine learning algorithms.

AVEC 2016 - Depression, Mood, and Emotion Recognition Workshop and Challenge

no code implementations5 May 2016 Michel Valstar, Jonathan Gratch, Bjorn Schuller, Fabien Ringeval, Denis Lalanne, Mercedes Torres Torres, Stefan Scherer, Guiota Stratou, Roddy Cowie, Maja Pantic

The Audio/Visual Emotion Challenge and Workshop (AVEC 2016) "Depression, Mood and Emotion" will be the sixth competition event aimed at comparison of multimedia processing and machine learning methods for automatic audio, visual and physiological depression and emotion analysis, with all participants competing under strictly the same conditions.

Emotion Recognition

A Multimodal Corpus for the Assessment of Public Speaking Ability and Anxiety

no code implementations LREC 2016 Mathieu Chollet, Torsten W{\"o}rtwein, Louis-Philippe Morency, Stefan Scherer

As such, tools enabling the improvement of public speaking performance and the assessment and mitigation of anxiety related to public speaking would be very useful.

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.

Denoising Emotion Classification +3

The Distress Analysis Interview Corpus of human and computer interviews

no code implementations LREC 2014 Jonathan Gratch, Ron artstein, Gale Lucas, Giota Stratou, Stefan Scherer, Angela Nazarian, Rachel Wood, Jill Boberg, David DeVault, Stacy Marsella, David Traum, Skip Rizzo, Louis-Philippe Morency

The Distress Analysis Interview Corpus (DAIC) contains clinical interviews designed to support the diagnosis of psychological distress conditions such as anxiety, depression, and post traumatic stress disorder.

An audiovisual political speech analysis incorporating eye-tracking and perception data

no code implementations LREC 2012 Stefan Scherer, Georg Layher, John Kane, Heiko Neumann, Nick Campbell

Additionally, we compare the gaze behavior of the human subjects to evaluate saliency regions in the multimodal and visual only conditions.
