Finding Temporal Patterns Using Constraints on
نویسنده
چکیده
When the evolution of variables over time is relevant to a classification task, established classifiers cannot be applied directly as the typical input format (data table) is not appropriate. We propose a new representation of temporal patterns that includes constraints on (partial) presence, (partial) absence as well as the duration of temporal predicates. A general-to-specific search-based algorithm is presented to derive classification rules. The approach evaluates promising on artificial and real data.

متن کاملInferring neuronal network connectivity from spike data: A temporal data mining approach
Understanding the functioning of a neural system in terms of its underlying circuitry is an important problem in neuroscience. Recent developments in electrophysiology and imaging allow one to simultaneously record activities of hundreds of neurons. Inferring the underlying neuronal connectivity patterns from such multi-neuronal spike train data streams is a challenging statistical and computat...
متن کاملInvestigating the Effect of Music on Spatial Learning in a Virtual Reality Task
Background: Spatial learning and navigation is a fundamental cognitive ability consisting of multiple cognitive components. Despite intensive efforts conducted with the assistance of virtual reality technology and functional Magnetic Resonance Imaging (fMRI) modality, the music effect on this cognition and the involved neuronal mechanisms remain elusive. Objectives: We aimed to investigate the...
متن کاملSTCSP: A Representation Model for Sequential Patterns
Temporal constraint satisfaction problem is a useful formalism for representing and reasoning about temporal occurrences and their temporal relationships. In this paper, we present a new temporal constraint satisfaction problem to deal with sequential patterns (STCSP). The problem is represented as a constraint satisfaction problem with sequential valuated variables, where multiple sequential v...

DEFINING AND USING REQUIREMENTS PATTERNS FOR EMBEDDED SYSTEMS By SASCHA J. KONRAD It is well-known that requirements modeling and analysis is one of the most difficult tasks in the software development process, but this problem is greatly exacerbated for embedded systems given the hardware constraints and the potentially complex control logic. This research investigates how an approach similar ...
