Visiting Research at Web Intelligence Group (WI), UCL.

I am a Visiting Researcher at Web Intelligence Group (WI) at the University College London (UCL), United Kingdom. I am working on problems at the intersection of Machine Learning and Information Retrieval. My research interests are mainly in recommender systems, bias and fairness, and conversational systems.

I completed my MSc in Computer Science from University of Zanjan (ZNU), where I was advised by Prof. Mohsen Afsharchi and Dr. Mitra Baratchi (co-supervisor from Leiden University) and worked on context-aware recommender systems. During my MSc studies, I had also spent four months visiting Information Retrival group (USI-IR) at the Università della Svizzera italiana (USI), working on information retrieval (IR) and recommender systems (RecSys) problems. My work was generously supported by a Swiss State Secretariat for Education, Research and Innovation (SERI) mobility grant. Also, I participated in the European Union project consists of Vienna University of Technology, University of Bonn, Aristotle University of Thessaloniki and two European SMEs focused on Data Science and Big Data. I received my B.Sc. degree from the University of Zanjan.

My full name is “HosseinAli Rahmani Dashti”, and my nickname is “Saeed”. I prefer to be called “Saeed” and generally everyone knows me by my nickname. But in academic and papers, I use the abbreviated “Hossein A. Rahmani” of my full name.
