Knowledge discovery from data streams

João Gama, Jesus Aguilar-Ruiz, João Gama, Jesus Aguilar-Ruiz
2007 Intelligent Data Analysis  
Examples include customer click streams, telephone records, large sets of web pages, multimedia data, and sets of retail chain transactions. These sources of continuous data are called data streams.  ...  Standard machine learning algorithms work on static data. Most of the times, all the data is loaded into memory and the learning task is solved by performing multiple scans over the training data.  ...  The common concept in all the papers is that learning occurs while data continuously flow.  ...

High-performance face tracking

Nenad Markuš, Miroslav Frljak, Igor S. Pandžić, Jörgen Ahlberg, Robert Forchheimer
2012 Proceedings of the 3rd Symposium on Facial Analysis and Animation - FAA '12  
Acknowledgements The core tracking algorithm has been developed by Visage Technologies AB, Linköping, Sweden and work continues in collaboration with the company.  ...  The obtained data is passed to the information form of extended Kalman filter (EIF) [Bar-Shalom et al. 2001 ]. The filter recursively estimates the rotation, translation and action parameters.  ...  It is robust, resistant to rapid changes in pose and facial expressions, does not suffer from drifting and is modestly computationally expensive. The tracker runs in real-time on mobile devices.  ...

Nayer Wanas, Ahmed Farouk, Dina Said, Nabila Khodeir, Magda Fayek
2019 International Journal of Computer Science & Information Technology (IJCSIT)  
Data modelling in IKCD uses k-means clustering to determine the occurrence of a drift while avoiding the dependency on the availability of data labels.  ...  However, data streams are highly prone to the phenomena of concept drift, in which the data distribution changes over time.  ...  One of the major issues facing RSs is that the user's interest, and/or the item features themselves may change over time especially for data streams that online users interact with [4] .  ...
