Learning Representations from Audio-Visual Spatial Alignment

NeurIPS 2020poster

We introduce a novel self-supervised pretext task for learning representations from audio-visual content. Prior work on audio-visual representation learning leverages correspondences at the video level. Approaches based on audio-visual correspondence (AVC) predict whether audio and video clips origi…

Self-Supervised Generation of Spatial Audio for 360° Video

NeurIPS 2018poster

We introduce an approach to convert mono audio recorded by a 360° video camera into spatial audio, a representation of the distribution of sound over the full viewing sphere. Spatial audio is an important component of immersive 360° video viewing, but spatial audio microphones are still rare in curr…

Large Margin Discriminant Dimensionality Reduction in Prediction Space

NeurIPS 2016poster

In this paper we establish a duality between boosting and SVM, and use this to derive a novel discriminant dimensionality reduction algorithm. In particular, using the multiclass formulation of boosting and SVM we note that both use a combination of mapping and linear classification to maximize the…
