How neural networks learn to classify chaotic time series

no code implementations4 Jun 2023 Alessandro Corbetta, Thomas Geert de Jong

In particular, we show that the relation between input periodicity and activation periodicity is key for the performance of LKCNN models.

Towards a Numerical Proof of Turbulence Closure

no code implementations18 Feb 2022 Giulio Ortali, Alessandro Corbetta, Gianluigi Rozza, Federico Toschi

The development of turbulence closure models, parametrizing the influence of small non-resolved scales on the dynamics of large resolved ones, is an outstanding theoretical challenge with vast applicative relevance.

Pedestrian orientation dynamics from high-fidelity measurements

no code implementations14 Jan 2020 Joris Willems, Alessandro Corbetta, Vlado Menkovski, Federico Toschi

We investigate in real-life conditions and with very high accuracy the dynamics of body rotation, or yawing, of walking pedestrians - an highly complex task due to the wide variety in shapes, postures and walking gestures.

Vocal Bursts Intensity Prediction

Deep learning velocity signals allows to quantify turbulence intensity

no code implementations13 Nov 2019 Alessandro Corbetta, Vlado Menkovski, Roberto Benzi, Federico Toschi

Turbulence, the ubiquitous and chaotic state of fluid motions, is characterized by strong and statistically non-trivial fluctuations of the velocity field, over a wide range of length- and time-scales, and it can be quantitatively described only in terms of statistical averages.

StampNet: unsupervised multi-class object discovery

1 code implementation7 Feb 2019 Joost Visser, Alessandro Corbetta, Vlado Menkovski, Federico Toschi

Unsupervised object discovery in images involves uncovering recurring patterns that define objects and discriminates them against the background.

Accurate pedestrian localization in overhead depth images via Height-Augmented HOG

no code implementations31 May 2018 Werner Kroneman, Alessandro Corbetta, Federico Toschi

We tackle the challenge of reliably and automatically localizing pedestrians in real-life conditions through overhead depth imaging at unprecedented high-density conditions.

BIG-bench Machine Learning Data Augmentation

Weakly supervised training of deep convolutional neural networks for overhead pedestrian localization in depth fields

no code implementations9 Jun 2017 Alessandro Corbetta, Vlado Menkovski, Federico Toschi

Even though hand-crafted image analysis algorithms are successful in many common cases, they fail frequently when there are complex interactions of multiple objects in the image.
