Low Data Learning
Pierre-André Noël is a Research Scientist at ServiceNow Research. His recent work involves graphs and/or diffusion. He holds a PhD in Physics from Université Laval and was a postdoctoral researcher at University of California Davis. His doctoral and postdoctoral research pertained to Complex Networks, Statistical Mechanics and Stochastic Processes. In 2017, he joined an NLP team at Element AI where he spent the following years building core capabilities and working on special projects. ServiceNow acquired Element AI in 2021, and Pierre-André now focuses on fundamental research.
