This paper present a technique for unsupervised learning algorithm for inferring important locations to be associated to a posssible custimization of the user interface of an application. The author departes from previous studies of inferring context extending the technique in such a way that would be possible to use the method on-the-fly and without the training period, which is impeding the development of such techniques on mobile devices.

The algorithm is called K-SCM and it is based on the idea to fuse several input sources into a string. The string is then associated to a matrix for which is calculated the variation and probability of presentation of a certain node at a certain time. Using solutions from the neural networks theory, the algorithm is able to select the winning node over a certain period of time that will define the winning location to be associated with the user interaction on the phone.
