On The Potential of The Fractal Geometry and The CNNs Ability to Encode it

no code implementations7 Jan 2024 Julia El Zini, Bassel Musharrafieh, Mariette Awad

In this work, we investigate the features that are learned by deep models and we study whether these deep networks are able to encode features as complex and high-level as the fractal dimensions.

Beyond Model Interpretability: On the Faithfulness and Adversarial Robustness of Contrastive Textual Explanations

1 code implementation17 Oct 2022 Julia El Zini, Mariette Awad

Accordingly, we extend the computation of three metrics, proximity, connectedness and stability, to textual data and we benchmark two successful contrastive methods, POLYJUICE and MiCE, on our suggested metrics.

On the Explainability of Natural Language Processing Deep Models

no code implementations13 Oct 2022 Julia El Zini, Mariette Awad

Such challenges can be attributed to the lack of input structure in textual data, the use of word embeddings that add to the opacity of the models and the difficulty of the visualization of the inner workings of deep models when they are trained on textual data.

The Power of Transfer Learning in Agricultural Applications: AgriNet

no code implementations8 Jul 2022 Zahraa Al Sahili, Mariette Awad

Additionally, all proposed models were found to accurately classify the 423 classes of plant species, diseases, pests, and weeds with a minimum accuracy of 87% for the Inception-v3 model. Finally, experiments to evaluate of superiority of AgriNet models compared to ImageNet models were conducted on two external datasets: pest and plant diseases dataset from Bangladesh and a plant diseases dataset from Kashmir.
