AMI-Class: Towards a Fully Automated Multi-view Image Classifier

27.09.2021
In this paper, we propose an automated framework for multi-view image classification tasks. The proposed framework is able to, all at once, train a model to find a common latent representation and perform data imputation, choose the best classifier and tune all necessary hyper-parameters.

Policy-based Automated Compliance Checking

27.07.2021
Under the GDPR requirements and privacy-by-design guidelines, access control for personal data should not be limited to a simple role-based scenario. For the processing to be compliant, additional attributes, such as the purpose of processing or legal basis, should be verified against an established data processing agreement or policy.

Anomaly Detection: How to Artificially Increase your F1-Score with a Biased Evaluation Protocol

30.06.2021
Anomaly detection is a widely explored domain in machine learning. Many models are proposed in the literature, and compared through different metrics measured on various datasets. The most popular metrics used to compare performances are F1-score, AUC and AVPR.

DAEMA: Denoising Autoencoder with Mask Attention

30.06.2021
Missing data is a recurrent and challenging problem, especially when using machine learning algorithms for real-world applications. For this reason, missing data imputation has become an active research area, in which recent deep learning approaches have achieved state-of-the-art results. We propose DAEMA: Denoising Autoencoder with Mask Attention.

Estimating Expected Calibration Errors

30.06.2021
Uncertainty in probabilistic classifiers predictions is a key concern when models are used to support human decision making, in broader probabilistic pipelines or when sensitive automatic decisions have to be taken. Studies have shown that most models are not intrinsically well calibrated, meaning that their decision scores are not consistent.

A Framework Using Contrastive Learning for Classification with Noisy Labels

11.06.2021
We propose a framework using contrastive learning as a pre-training task to perform image classification in the presence of noisy labels. Recent strategies, such as pseudo-labelling, sample selection with Gaussian Mixture models, and weighted supervised contrastive learning have been combined into a fine-tuning phase following the pre-training.

AMU-EURANOVA at CASE 2021 Task 1: Assessing the stability of multilingual BERT

11.06.2021
This paper explains our participation in task 1of the CASE 2021 shared task. This task is about multilingual event extraction from the news. We focused on sub-task 4, event information extraction. This sub-task has a small training dataset, and we fine-tuned a multilingual BERT to solve this sub-task.

Our Research Director Invited as PC Member at IEEE Big Data

10.05.2021
We are very proud of our research director Sabri Skhiri for joining the program committee of IEEE Big Data 2021! He will be the only Belgian and one of the few Europeans to be on the program committee of this top tier research conference in Big Data. Congratulation Sabri!

A Combined Rule-Based and Machine Learning Approach for Automated GDPR Compliance Checking

19.04.2021
The General Data Protection Regulation (GDPR) requires data controllers to implement end-to-end compliance. Controllers must therefore ensure that the terms agreed with the data subject and their own obligations under GDPR are respected in the data flows from data subject to controllers, processors and sub-processors (i.e. data supply chain).
