2022-current External Associate Researcher in XAI & Cognitive sciences

DECIDE Team, IMT Atlantique, Lab-STICC, UMR CNRS 6285, F-29238 Brest, France

Abstract: As a continuation of my postdoc and as an opening to this one, I am working on the extraction of explainable knowledge in order to generate multi-modal explanations according to the level of expertise of the target audience. Through this topic, I also explore what are the elements impacting the acceptability and the perception of what is a good explanation. Several research topics are conducted in parallel:

• The generation of multimodal explanations from heterogeneous data
• The generation of visual explanations thanks to the interpretability of CNNs
• Biases and their impact on the management of AI projects: cognitive, statistical and algorithmic biases
• The impact of context in the acceptability of an explanation

Thesis title: ”Learning sequences and extracting rules from recurrent networks: application to the drawing of technical diagrams.”

Supervisors: Frédéric Alexandre, Head of Mnemosyne team, and Nicolas Rougier, INRIA Researcher

Abstract: The implicit knowledge of an individual is acquired in two ways. The first one consists of the repetition of sequences, which allows the individual to implicitly extract regularities. The second way is a migration from explicit knowledge to implicit knowledge due to development expertise. Both are implicit learning. In our work, we wanted to look at the sequences of components that are used in the and in particular the problem of extracting implicit rules in these sequences, an important aspect of the extraction of business expertise from technical drawings. We place ourselves in the connective field, in particular, we have considered neural models capable of processing sequences. We have implemented two neural networks recurrent: Elman’s model, the Simple Recurrent Network, and a model with LSTM (Long Short Term Memory) units. We evaluated these two models on different artificial grammars (Reber’s grammar and its variations) in terms of learning, their ability to generalize from this one, and their management of sequential dependencies. Finally, we have also shown that it was possible to extract the encoded rules (from the sequences) in the recurrent network equipped with LSTM, in the form of an automaton. The electrical field is particularly relevant to this issue because it is more constrained (more combinatorial and less combinatorial) than task scheduling in more general cases such as navigation for example, which could constitute a perspective of this work.
