Explaining, Analyzing, and Probing Representations of Self-Supervised Learning Models for Sensor-based Human Activity Recognition

no code implementations14 Apr 2023 Bulat Khaertdinov, Stylianos Asteriadis

In recent years, self-supervised learning (SSL) frameworks have been extensively applied to sensor-based Human Activity Recognition (HAR) in order to learn deep representations without data annotations.

Unsupervised Interpretable Basis Extraction for Concept-Based Visual Explanations

no code implementations19 Mar 2023 Alexandros Doumanoglou, Stylianos Asteriadis, Dimitrios Zarpalas

An important line of research attempts to explain CNN image classifier predictions and intermediate layer representations in terms of human understandable concepts.

Contrastive Learning with Cross-Modal Knowledge Mining for Multimodal Human Activity Recognition

1 code implementation20 May 2022 Razvan Brinzea, Bulat Khaertdinov, Stylianos Asteriadis

We extend a number of recent contrastive self-supervised approaches for the task of Human Activity Recognition, leveraging inertial and skeleton data.

Being the center of attention: A Person-Context CNN framework for Personality Recognition

no code implementations15 Oct 2019 Dario Dotti, Mirela Popa, Stylianos Asteriadis

Experiments on two public datasets demonstrate the effectiveness of jointly modeling the mutual Person-Context information, outperforming the state-of-the art-results for personality recognition in two different scenarios.
