Learning novel concepts: beyond one-class
Joao Gama
Video in druga učna gradiva
Oznake:
OLINDDA (OnLIne Novelty and Drift Detection Algorithm) addresses the problem of novelty detection in an online continuous learning scenario as an extension to a single-class classification problem. This paper presents its current version, that evolved toward the discovery of new concepts initially a ...

Data Stream Mining for Ubiquitous Environments
Joao Gama
Video in druga učna gradiva
Oznake: computer science;data mining
In the data stream computational model examples are processed once, using restricted computational resources and storage capabilities. The goal of data stream mining consists of learning a decision model, under these constraints, from sequences of observations generated from environments with unknow ...

Issues in Evaluation of Stream Learning Algorithms
Joao Gama
Video in druga učna gradiva
Oznake: computer science;data mining;temporal & streams mining
Learning from data streams is a research area of increasing importance. Nowadays, several stream learning algorithms have been developed. Most of them learn decision models that continuously evolve over time, run in resource-aware environments, detect and react to changes in the environment generati ...

Clustering Distributed Sensor Data Streams
Pedro Pereira Rodrigues , Joao Gama , Luis Lopes
Video in druga učna gradiva
Oznake: computer science;machine learning;clustering;sensor networks
In this work we study the problem of continuously maintain a cluster structure over the data points generated by a sensor network. We propose DGClust, a new distributed algorithm which reduces both the dimensionality and the communication burdens, by allowing each local sensor to keep an online disc ...
