On Thursday evening, we had the pleasure of hosting another tech event at our Lille office, focusing on a topic that was as specialised as it was fascinating: reranking using Transformers 👨‍💻🚀

A big thank you to Alex LENFANT for this highly informative presentation, based on his work at Objectware for ADEO ✨

On the agenda:

🔹 Fine-tuning a cross-encoder on a category/product corpus using Multiple Negative Ranking Loss

🔹 Mining hard negatives using a bi-encoder

🔹 Curriculum Learning to improve performance on complex cases

🔹 Fusion of web signals and semantic scores to enhance ranking consistency

🔹 Measuring impact via NDCG 📊

A highly enriching evening, combining applied research, real-world business challenges and feedback from the field 💡

👏 Thanks also to everyone who joined us in person and remotely for the discussions and camaraderie during this tech evening!
