REWIND Dataset: Privacy-preserving Speaking Status Segmentation from Multimodal Body Movement Signals in the Wild

no code implementations2 Mar 2024 Jose Vargas Quiros, Chirag Raman, Stephanie Tan, Ekin Gedik, Laura Cabrera-Quiros, Hayley Hung

In addition to providing the signals and ground truth necessary to evaluate a wide range of speaking status detection methods, the availability of audio in REWIND makes it suitable for cross-modality studies not feasible with previous mingling datasets.

Mesh-Tension Driven Expression-Based Wrinkles for Synthetic Faces

no code implementations5 Oct 2022 Chirag Raman, Charlie Hewitt, Erroll Wood, Tadas Baltrusaitis

Recent advances in synthesizing realistic faces have shown that synthetic training data can replace real data for various face-related computer vision tasks.

Why Did This Model Forecast This Future? Closed-Form Temporal Saliency Towards Causal Explanations of Probabilistic Forecasts

no code implementations1 Jun 2022 Chirag Raman, Hayley Hung, Marco Loog

In this work, we introduce and address the following question: given a probabilistic forecasting model how can we identify observed windows that the model considers salient when making its forecasts?

ConfLab: A Data Collection Concept, Dataset, and Benchmark for Machine Analysis of Free-Standing Social Interactions in the Wild

1 code implementation10 May 2022 Chirag Raman, Jose Vargas-Quiros, Stephanie Tan, Ashraful Islam, Ekin Gedik, Hayley Hung

Recording the dynamics of unscripted human interactions in the wild is challenging due to the delicate trade-offs between several factors: participant privacy, ecological validity, data fidelity, and logistical overheads.

Towards a Real-time Measure of the Perception of Anthropomorphism in Human-robot Interaction

1 code implementation24 Jan 2022 Maria Tsfasman, Avinash Saravanan, Dekel Viner, Daan Goslinga, Sarah de Wolf, Chirag Raman, Catholijn M. Jonker, Catharine Oertel

43 English-speaking participants took part in the study for whom we analysed the degree of acoustic-prosodic entrainment to the human or robot face, respectively.

Social Processes: Self-Supervised Meta-Learning over Conversational Groups for Forecasting Nonverbal Social Cues

1 code implementation NeurIPS 2021 Chirag Raman, Hayley Hung, Marco Loog

In this way, an SP model learns to adapt its forecasts to the unique dynamics of the interacting partners, generalizing to unseen groups in a data-efficient manner.

A Modular Approach for Synchronized Wireless Multimodal Multisensor Data Acquisition in Highly Dynamic Social Settings

no code implementations9 Aug 2020 Chirag Raman, Stephanie Tan, Hayley Hung

In this work, we propose a modular and cost-effective wireless approach for synchronized multisensor data acquisition of social human behavior.

Towards automatic estimation of conversation floors within F-formations

no code implementations19 Jul 2019 Chirag Raman, Hayley Hung

We motivate a metric for the existence of distinct conversation floors based on simultaneous speaker turns, and provide an analysis using this metric to characterize conversations across F-formations of varying cardinality.
