PILOT: Introducing Transformers for Probabilistic Sound Event Localization

1 code implementation7 Jun 2021 Christopher Schymura, Benedikt Bönninghoff, Tsubasa Ochiai, Marc Delcroix, Keisuke Kinoshita, Tomohiro Nakatani, Shoko Araki, Dorothea Kolossa

Sound event localization aims at estimating the positions of sound sources in the environment with respect to an acoustic receiver (e. g. a microphone array).

Event Detection

Exploiting Attention-based Sequence-to-Sequence Architectures for Sound Event Localization

1 code implementation28 Feb 2021 Christopher Schymura, Tsubasa Ochiai, Marc Delcroix, Keisuke Kinoshita, Tomohiro Nakatani, Shoko Araki, Dorothea Kolossa

Herein, attentions allow for capturing temporal dependencies in the audio signal by focusing on specific frames that are relevant for estimating the activity and direction-of-arrival of sound events at the current time-step.

Joining Sound Event Detection and Localization Through Spatial Segregation

1 code implementation29 Mar 2019 Ivo Trowitzsch, Christopher Schymura, Dorothea Kolossa, Klaus Obermayer

This work presents an approach that robustly binds localization with the detection of sound events in a binaural robotic system.

Audiovisual Speaker Tracking using Nonlinear Dynamical Systems with Dynamic Stream Weights

1 code implementation14 Mar 2019 Christopher Schymura, Dorothea Kolossa

This paper presents a framework that extends the well-established theory of nonlinear dynamical systems with the notion of dynamic stream weights for an arbitrary number of sensory observations.
