We are looking for an enthusiastic and talented student interested in novel technologies and in their evolution, to work on A Generic and Model-Agnostic Evaluation Framework for Decision-Making Tasks such as Task-Oriented Dialogue.
The candidate will join the team NADIA (Natural Dialogue Interaction) in the R&D division of Orange at Lannion Brittany France (a charm and touristic city next to the sea: http://www.bretagne-cotedegranitrose.com/ , https://www.lannion.bzh/). Similarly, the PhD student will enrol at the University of Marseille, and will be attached to the laboratory LIS (Laboratoire d’Informatique et Systèmes).
The candidate must hold a Master’s degree in Computer Science, Mathematics, Engineering or a related field, with a high mathematical level (optimisation, statistics and probability theory). Programming skills are absolutely necessary. Understanding autoregressive generative models is very important.
Experience in Machine Learning, Deep Learning and AI is desired, as well as mastering deep learning modules such as Torch, pyTorch and TensorFlow. Fluent English level is required, while knowing French is not essential.

PhD- A Generic and Model-Agnostic Evaluation Framework for Decision-Making Tasks (e.g. Task-Oriented Dialogue)
Abstract:
Orange has implemented various bot solutions, and records large amounts of human-machine and human-to-human conversations for customer care. Often, these conversations are not rigorously evaluated.
Large language models (LLMs) are a breakthrough in many natural language processing (NLP) tasks, including the development of agents capable of solving complex tasks [6]. Moreover, developing chatbots has become democratized. It is likely that there will be a proliferation of solutions in the near future. The boundaries between various NLP tasks and the domains (e.g. tourism, restaurant, retail, technical support, etc.) are blurring.
The evaluation of the various solutions is becoming a real need, it is necessary to broaden the scope of evaluation and to make it transposable.
Previous work studied the correlation between objective and subjective metrics (indicators) to evaluate conversations [3] and for text generation [6]. Others predicted the quality of the conversation [1]. Model-agnostic scores are proposed in [4] to compare the behaviour of two dialogue systems. Recently the DSTC (Dialogue System Technology Challenge) has been focused on the evaluation of dialogues [5].
Inspired by the game theory [7], interpretability [2] and self-driving cars [8], we would like to infer the strategy that has been followed by the dialogue system [10] in order to evaluate it under distinct perspectives. We will work both on public (WebShop, ALFWorld,...) and private Orange (Technical Assistance, Commercial Bots, etc.) datasets.
