This course focus on deeper understanding of user preferences/needs/requirements. The problem depends both on the user seniority, visits frequency or the particular domain in question. We will focus e.g. on proportionality, preference drift, multicriteriality, unbiased evaluation and on algorithms capable to learn and recommend from such data. We will also focus on a wider context of preference interpretation, e.g. during search (strict/fuzzy preference, graphical interpretation). Labs will mainly focus on refering about recent papers and a virtual "Lean startup" project.
