Amin Allahyar I recieved my MSc in Computer Engineering - Artificial Intelligence from Ferdowsi University of Mashhad, Iran. I am also a member of the Pattern Recognition Lab led by Dr Hadi Sadoghi, working on Machine Learning and Pattern Recognition. My current research focuses on Online Semi-Supervised Clustering. I am looking for ways to incorporate available domain knowledge to clustering stream data. I am also interested in other clustering problems such as Spectral Clustering and Self Organizing Maps.
