Comparing Self-Supervised Learning Techniques for Wearable Human Activity Recognition

no code implementations8 Apr 2024 Sannara Ek, Riccardo Presotto, Gabriele Civitarese, François Portet, Philippe Lalanda, Claudio Bettini

Although supervised learning methods are the most effective in this task, their effectiveness is constrained to using a large amount of labeled data during training.

Combining Public Human Activity Recognition Datasets to Mitigate Labeled Data Scarcity

1 code implementation23 Jun 2023 Riccardo Presotto, Sannara Ek, Gabriele Civitarese, François Portet, Philippe Lalanda, Claudio Bettini

In this paper, we propose a novel strategy to combine publicly available datasets with the goal of learning a generalized HAR model that can be fine-tuned using a limited amount of labeled data on an unseen target domain.

Evaluation and comparison of federated learning algorithms for Human Activity Recognition on smartphones

no code implementations30 Oct 2022 Sannara Ek, François Portet, Philippe Lalanda, German Vega

Unfortunately, however, the most popular federated learning algorithms have been shown not to be adapted to some highly heterogeneous pervasive computing environments.

Lightweight Transformers for Human Activity Recognition on Mobile Devices

1 code implementation22 Sep 2022 Sannara Ek, François Portet, Philippe Lalanda

Human Activity Recognition (HAR) on mobile devices has shown to be achievable with lightweight neural models learned from data generated by the user's inertial measurement units (IMUs).
