The model is based onfine-tuning LLaMA 2 with LoRA.- Participed on share tasks: OSACT 2020, HASOC 2022, and HASOC 2023, SemEval 2022.
- Aquila Data EnablerSenior Applied Scientist NLPE-COMMERCEmars 2020 - septembre 2020 (7 mois)Paris, FranceParticipated in the implementation of a question-answering system using a large database of PDFdocuments. The implemented model is based on fine-tuned BERT and TAPAS transformers.
- EpitaAnalyse des sentiments, Chatbot, Reconnaissance d'entités nomméesRÉSEAUX SOCIAUXoctobre 2017 - Aujourd'hui (8 ans et 8 mois)Paris, FranceWorked on different projects: detecting emotions in textual conversations, dialect identification andsentiment analysis.+ Developed a system for classifying textual dialogues into emotion classes such as Angry, Happy, Sad,and Others. Utilized various deep neural network techniques including Recurrent Neural Networks(LSTM, B-LSTM, GRU, B-GRU), Convolutional Neural Network (CNN), and Transfer Learning (TL).+ Developed a system for classifying comments into one of 26 classes, corresponding to various dialectsof Arabic language. The implemented system based on Recurrent Neural Networks (BLSTM, BGRU)using hierarchical classification. We started with a higher level of classification (8 classes) and thenperformed the finer-grained classification (26 classes).+ Developed a system for classifying tweets into one of seven classes, corresponding to various levelsof positive and negative sentiment intensity, that best represents the mental state of the tweeter. Themain idea of our solution is to use transfer learning, which allows to avoid learning from scratch.Indeed, we start to train a first model to predict if a tweet is positive, negative or neutral. For thiswe use an external dataset which is larger and similar to the target dataset. Then, the pre-trainedmodel is re-used as the starting point to train a new model that classifies a tweet into one of the sevenvarious levels of sentiment intensity.
