Detach-ROCKET: Sequential feature selection for time series classification with random convolutional kernels

1 code implementation25 Sep 2023 Gonzalo Uribarri, Federico Barone, Alessio Ansuini, Erik Fransén

When applied to the largest binary UCR dataset, Detach-ROCKET is able to improve test accuracy by $0. 6\%$ while reducing the number of features by $98. 9\%$.

CARSO: Blending Adversarial Training and Purification Improves Adversarial Robustness

1 code implementation25 May 2023 Emanuele Ballarin, Alessio Ansuini, Luca Bortolussi

In this work, we propose a novel adversarial defence mechanism for image classification - CARSO - blending the paradigms of adversarial training and adversarial purification in a mutually-beneficial, robustness-enhancing way.

Hierarchical nucleation in deep neural networks

1 code implementation NeurIPS 2020 Diego Doimo, Aldo Glielmo, Alessio Ansuini, Alessandro Laio

This process leaves a footprint in the probability density of the output layer where the topography of the peaks allows reconstructing the semantic relationships of the categories.

Intrinsic dimension of data representations in deep neural networks

1 code implementation NeurIPS 2019 Alessio Ansuini, Alessandro Laio, Jakob H. Macke, Davide Zoccolan

We find that, in a trained network, the ID is orders of magnitude smaller than the number of units in each layer.
