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.

Learning Unbiased Representations via Mutual Information Backpropagation

1 code implementation13 Mar 2020 Ruggero Ragonesi, Riccardo Volpi, Jacopo Cavazza, Vittorio Murino

We are interested in learning data-driven representations that can generalize well, even when trained on inherently biased data.

Generative Pseudo-label Refinement for Unsupervised Domain Adaptation

2 code implementations9 Jan 2020 Pietro Morerio, Riccardo Volpi, Ruggero Ragonesi, Vittorio Murino

We exploit this finding in an iterative procedure where a generative model and a classifier are jointly trained: in turn, the generator allows to sample cleaner data from the target distribution, and the classifier allows to associate better labels to target samples, progressively refining target pseudo-labels.
