Finding frequent patterns from data

Finding frequent patterns from data

Posted in Science

Discovery of frequent patterns = finding positive conjunctions that are true for a given fraction of the observations - this basic idea can be instantiated in many ways: - finding frequent sets from 0/1 data (association mining) - finding frequent episodes in sequences - finding frequent subgraphs in graphs etc. - efficient algorithms exist -- the levelwise approach - theoretical analysis of th...

Patterns in sets of points: an overview

Patterns in sets of points: an overview

Posted in Science

1 - "Patterns in sets of points: an overview" "We illustrate the importance of optimization principles in the search for interesting patterns, more in particular for patterns in sets of points embedded in a metric space. This talk will be a journey along the types of patterns in point sets that can efficiently be searched for, and general principles will be outlined. We provide examples from di...

Suffix tree and Hidden Markov techniques for pattern analysis

Suffix tree and Hidden Markov techniques for pattern analysis

Posted in Science

Suffix tree construction. Mention the new linear time array constructions - - using suffix trees for finding motifs with gaps (some new observations: 0.5 - 1 hours). - finding cis-regulatory motifs by comparative genomics (1 hour) - Hidden Markov techniques for haplotypingAuthor: Esko Ukkonen, University Of Helsinki

Statistical Aspects of Pattern Analysis

Statistical Aspects of Pattern Analysis

Posted in Science

Abstract: The lectures will introduce the role of statistics in pattern analysis with a discussion of the difference between pattern significance and pattern stability. We will go on to discuss composite hypothesis testing and the Bonferroni correction. Concentration inequalities will be introduced and used to assess the statistical reliability of empirical estimates. We move to consider unifor...

Fast Best-Effort Pattern Matching in Large Attributed Graphs

Fast Best-Effort Pattern Matching in Large Attributed Graphs

Posted in Science

We focus on large graphs where nodes have attributes, such as a social network where the nodes are labelled with each person’s job title. In such a setting, we want to find subgraphs that match a user query pattern. For example, a ‘star’ query would be, “find a CEO who has strong interactions with a Manager, a Lawyer, and an Accountant, or another structure as close to that as possible”. Simila...

A general purpose segmentation algorithm using analytically evaluated random walks

A general purpose segmentation algorithm using analytically evaluated random walks

Posted in Science

An ideal segmentation algorithm could be applied equally to the problem of isolating organs in a medical volume or to editing a digital photograph without modifying the algorithm, changing parameters, or sacrificing segmentation quality. However, a general-purpose, multiway segmentation of objects in an image/volume remains a challenging problem. In this talk, I will describe a recently develop...
