My name is Ioannis Psarros and I am a 2nd year Phd student at the University of Athens, Greece, under the supervision of Prof. Ioannis Z. Emiris. After graduating from the school of Informatics and Telecommunications in the University of Athens I attended the interdepartmental Graduate Program in Logic, Algorithms and Computation at the same university. I am now a member of the Laboratory of Algebraic and Geometric Algorithms .
Low-quality dimension reduction and high-dimensional Approximate Nearest Neighbor. Joint work with E. Anagnostopoulos and I. Z. Emiris. In Proc. of 31th International Symposium on Computational Geometry, 2015. Updated version in arXiv.
Practical linear-space Approximate Near Neighbors in high dimension. Joint work with G. Avarikioti, I. Z. Emiris and G. Samaras. Submitted. Also in arXiv. Implemented by G. Samaras and available at Github. My implementation in Python: DolphinnPy.
