Sotirios Panagiotis (Takis) Chytas I am an AI Research Scientist in Apple Maps. Before that, I completed my PhD in Computer Sciences at University of Wisconsin-Madison, working with Professor Vikas Singh. Prior to that, I obtained my Diploma and my Master's degree at University of Thessaly in Greece. During my PhD studies, I had also been part of the Lawrence Livermore National Laboratory, closely working with Dr. Rudrasis Chakraborty as well as Apple Maps Research, closely working with Dr. Feili Hou. |

ResearchMy general expertise lies in Machine/Deep Learning, with my main focus, during my PhD studies, being on structure encoding in latent spaces. My goal is to combine ideas from multiple fields (machine learning, algorithms, optimization, differential and abstract algebra) so that I offer new capabilities or improve existing solutions. |
