Séminaire Valda : Anantha Padmanabha
20 mai 2022, 10:30-11:30. ENS S16. Algorithm for consistent query answering under primary key constraints Databases often have constraints. One of the basic constraints is the « primary key constraint » which states there can be at most one tuple for every primary key. However, these days it is common to have…
Séminaire Valda : Yann Ramusat
12 avril 2022, 10:30-11:30. ENS, S16 The Semiring-Based Provenance Framework for Graph Databases L’augmentation du volume de données collectées par des capteurs et générées par des interactions humaines a mené à l’utilisation des bases de données orientées graphes en tant que modèle de représentation efficace pour les données complexes. Les…
Séminaire Valda : Michaël Thomazo
8 avril 2022, 10:30-11:30. ENS, S16 Capturing Homomorphism-Closed Decidable Queries with Existential Rules Existential rules are a well studied ontology-mediated query language for which the chase represents a generic computational approach for query answering. It is straightforward that existential rule queries exhibiting chase termination are decidable and can only recognize…
Séminaire Valda : Debabrota Basu
Debabrota Basu, Inria Lille. 11 mars 2022, 10:30-11:30. ENS S16. Verifying and Explaining Unfairness of Machine Learning Algorithms In recent years, machine learning (ML) algorithms have been deployed in safety-critical and high-stake decision-making, where the fairness or unbiasedness of algorithms bears significant importance. Fairness in ML centres on detecting bias…
