Identifying Correlated Heavy-Hitters in a Two-Dimensional Data Stream [PDF]

open access: yes, 2013
We consider online mining of correlated heavy-hitters from a data stream. Given a stream of two-dimensional data, a correlated aggregate query first extracts a substream by applying a predicate along a primary dimension, and then computes an aggregate ...

MIDAS: Open-source framework for distributed online analysis of data streams

open access: yesSoftwareX, 2018
Data streams are pervasive but implementing online analysis of streaming data is often nontrivial as data streams can have different, domain-specific formats.

An efficient closed frequent itemset miner for the MOA stream mining system [PDF]

open access: yes, 2013
Mining itemsets is a central task in data mining, both in the batch and the streaming paradigms. While robust, efficient, and well-tested implementations exist for batch mining, hardly any publicly available equivalent exists for the streaming scenario ...

Towards online concept drift detection with feature selection for data stream classification [PDF]

open access: yes, 2016
Data Streams are unbounded, sequential data instances that are generated very rapidly. The storage, querying and mining of such rapid flows of data is computationally very challenging.

The ABACOC Algorithm: a Novel Approach for Nonparametric Classification of Data Streams

open access: yes, 2015
Stream mining poses unique challenges to machine learning: predictive models are required to be scalable, incrementally trainable, must remain bounded in size (even when the data stream is arbitrarily long), and be nonparametric in order to achieve high ...
