SyntaxShap: Syntax-aware Explainability Method for Text Generation

no code implementations14 Feb 2024 Kenza Amara, Rita Sevastjanova, Mennatallah El-Assady

We adopt a model-based evaluation to compare SyntaxShap and its weighted form to state-of-the-art explainability methods adapted to text generation tasks, using diverse metrics including faithfulness, complexity, coherency, and semantic alignment of the explanations to the model.

PowerGraph: A power grid benchmark dataset for graph neural networks

no code implementations5 Feb 2024 Anna Varbella, Kenza Amara, Blazhe Gjorgiev, Giovanni Sansavini

To this aim, we develop a graph dataset for cascading failure events, which are the major cause of blackouts in electric power grids.

GInX-Eval: Towards In-Distribution Evaluation of Graph Neural Network Explanations

no code implementations28 Sep 2023 Kenza Amara, Mennatallah El-Assady, Rex Ying

Diverse explainability methods of graph neural networks (GNN) have recently been developed to highlight the edges and nodes in the graph that contribute the most to the model predictions.

GraphFramEx: Towards Systematic Evaluation of Explainability Methods for Graph Neural Networks

1 code implementation20 Jun 2022 Kenza Amara, Rex Ying, Zitao Zhang, Zhihao Han, Yinan Shan, Ulrik Brandes, Sebastian Schemm, Ce Zhang

As GNN models are deployed to more mission-critical applications, we are in dire need for a common evaluation protocol of explainability methods of GNNs.

ReforesTree: A Dataset for Estimating Tropical Forest Carbon Stock with Deep Learning and Aerial Imagery

no code implementations26 Jan 2022 Gyri Reiersen, David Dao, Björn Lütjens, Konstantin Klemmer, Kenza Amara, Attila Steinegger, Ce Zhang, Xiaoxiang Zhu

The potential for impact and scale of leveraging advancements in machine learning and remote sensing technologies is promising but needs to be of high quality in order to replace the current forest stock protocols for certifications.

Nearest neighbor search with compact codes: A decoder perspective

no code implementations17 Dec 2021 Kenza Amara, Matthijs Douze, Alexandre Sablayrolles, Hervé Jégou

Modern approaches for fast retrieval of similar vectors on billion-scaled datasets rely on compressed-domain approaches such as binary sketches or product quantization.
