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. ...

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] . ...
