Title of talk: Learning as tensor completion
Abstract: Function approximation from input and output data pairs constitutes a fundamental problem in supervised learning. Deep neural networks are currently the most popular method for this task, but they are not interpretable and they do not work well with limited training. Tsetlin machines learn logical clauses from the input-output data, which is more parsimonious and interpretable. In this work, I will explain that identifying a general nonlinear function y=ƒ (x_1, …, x_N) of categorical (e.g., binary) variables x_1, …, x_N from input-output examples can be viewed as a tensor completion problem. This is important because provably correct nonlinear function identification is possible in this way, under certain reasonable conditions. Furthermore, I will explain how to extend this approach to the case of multivariate functions of continuous variables, which are not tensors in their native form. I will illustrate how well this idea works, even with limited training data, using various real-world classification tasks. Time permitting, I will provide a sneak preview of recent work (joint with Vladimir Zadorozhny) on interpretability.

Keynote Speaker 21 June 2022:
Dr. Veronique Ventos, Founding Head of Research, NukkAI and professor at University Paris Saclay.
Dr Véronique Ventos has a PhD in Artificial Intelligence and was an Associate Professor at Paris-Sud University where she investigated Logical Knowledge Representation and Symbolic Machine Learning. She is also a world reference in the field of AI applied to games.
In 2018 she cofounded NukkAI http://www.nukk.ai where as Head of Research she leads research on hybrid AI. NukkAI is committed to creating new generation AIs at the service of humans instead of replacing them and uses as a sandbox the game of Bridge which has resisted AI so far, unlike chess or Go.
In 2022 her team achieved a major scientific breakthrough when Nook, the hybrid explainable AI designed by NukkAI, beat 8 world champions at a Bridge challenge that took place in Paris.
Title of talk: Nook: a new generation AI dedicated to the game of Bridge
Abstract: On March 25 2022, at the end of a two-day Bridge tournament against eight world champions the Bridge AI Nook was declared victorious. This is a world première the game of bridge still being a great challenge to Artificial Intelligence.
NooK is a new generation AI according to several aspects. The first one is related to the fact that Nook is hybrid since it is made up of symbolic rule-based modules and neural network one. Rather than learning by playing a huge amount of games, it begins by recovering and modeling human expertise in a Background Knowledge described using a relational logic. Moreover Nook is able to provide explanations related to each decision.
The robot is developed by NukkAI, a French start-up that we will present at the start of the talk. In the following we will give the basics of the game of bridge and its distinguishing characteristics from other mind games The other two parts will be devoted to the challenge and the description of the NooK modules.
