Leveraging Acoustic Images for Effective Self-Supervised Audio Representation Learning

1 code implementation ECCV 2020 Valentina Sanguineti, Pietro Morerio, Niccolò Pozzetti, Danilo Greco, Marco Cristani, Vittorio Murino

However, since 2D planar arrays are cumbersome and not as widespread as ordinary microphones, we propose that the richer information content of acoustic images can be distilled, through a self-supervised learning scheme, into more powerful audio and visual feature representations.

From Biased Data to Unbiased Models: a Meta-Learning Approach

no code implementations29 Sep 2021 Ruggero Ragonesi, Valentina Sanguineti, Jacopo Cavazza, Vittorio Murino

It is well known that large deep architectures are powerful models when adequately trained, but may exhibit undesirable behavior leading to confident incorrect predictions, even when evaluated on slightly different test examples.

Audio-Visual Model Distillation Using Acoustic Images

1 code implementation16 Apr 2019 Andrés F. Pérez, Valentina Sanguineti, Pietro Morerio, Vittorio Murino

In this paper, we investigate how to learn rich and robust feature representations for audio classification from visual data and acoustic images, a novel audio data modality.
