Ilya Sutskever — Education: PhD in Machine Learning, University of Toronto (advisor: Geoffrey Hinton)

NoteThe source directly confirms all elements of the claim: (1) PhD from University of Toronto in 2013, (2) advisor was Geoffrey Hinton, (3) BSc from University of Toronto (2005, in mathematics), and (4) MSc from University of Toronto (2007, in computer science). The only minor discrepancy is that the source specifies the PhD was in 'computer science' rather than 'machine learning', but this is a standard disciplinary classification and does not contradict the claim's substance—machine learning is a subfield of computer science, and the thesis title 'Training Recurrent Neural Networks' confirms the ML focus. The infobox also lists 'PhD' under Education with University of Toronto.
