MIQCQP reformulation of the ReLU neural networks Lipschitz constant estimation problem

Autor: Sbihi, Mohammed, Jan, Sophie, Couellan, Nicolas

It is well established that to ensure or certify the robustness of a neural network, its Lipschitz constant plays a prominent role. However, its calculation is NP-hard. In this note, by taking into account activation regions at each layer as new cons

Sentiment analysis in Tourism: Fine-tuning BERT or sentence embeddings concatenation?

Autor: Bouabdallaoui, Ibrahim, Guerouate, Fatima, Bouhaddour, Samya, Saadi, Chaimae, Sbihi, Mohammed

Undoubtedly that the Bidirectional Encoder representations from Transformers is the most powerful technique in making Natural Language Processing tasks such as Named Entity Recognition, Question & Answers or Sentiment Analysis, however, the use of tr

Robust SVM Optimization in Banach spaces

Autor: Sbihi, Mohammed, Couellan, Nicolas

We address the issue of binary classification in Banach spaces in presence of uncertainty. We show that a number of results from classical support vector machines theory can be appropriately generalised to their robust counterpart in Banach spaces. T

A bang-bang principle for the conditional expectation vector measure

Autor: Askoura, Youcef, Sbihi, Mohammed

We prove a conditional expectation bang-bang principle. Based on properties of the conditional expectation vector measure, we establish that the conditional expectation of a set-valued mapping coincides with the conditional expectation of the set of
