Semi-supervised Kernel Metric Learning Using Relative Comparisons
Ehsan Amid, Aristides Gionis, Antti Ukkonen
We consider the problem of metric learning subject to a set of constraints on relative-distance comparisons between the data items. Such constraints are meant to reflect side-infor…
Finding Statistically Significant Attribute Interactions
Andreas Henelius, Antti Ukkonen, Kai Puolamäki
In many data exploration tasks it is meaningful to identify groups of attribute interactions that are specific to a variable of interest. For instance, in a dataset where the attri…
Estimating the pattern frequency spectrum inside the browser
Matthijs van Leeuwen, Antti Ukkonen
We present a browser application for estimating the number of frequent patterns, in particular itemsets, as well as the pattern frequency spectrum. The pattern frequency spectrum i…
Approximate Top-k Retrieval from Hidden Relations
Antti Ukkonen
We consider the evaluation of approximate top-k queries from relations with a-priori unknown values. Such relations can arise for example in the context of expensive predicates, or…
