QTempIntMiner : quantitative temporal sequence mining

QTempIntMiner (Quantitative Temporal Interval Miner) is a software that implements the QTempIntMiner algorithm presented in section 1 .

The software is mainly implemented in Matlab. It uses the Mixmod toolbox [39] to compute multi-dimensional Gaussian distributions. The main features of QTempIntMiner are:

• a generator of synthetic noisy sequences of temporal events,

• an implementation of the QTempIntMiner algorithm,

• a graphical interface that enables the user to generate or import data set and to define the parameters of the algorithm. The interfaces although displays the extracted temporal patterns.

This year, the software has been updated to mine long sequences of temporal events such as cardiac monitoring annotations. Long sequences are transformed into short temporal sequences that are used as instances of the QTempIntMiner algorithm. The software is currently applied to the characterisation of cardiac arrythmias.

The following website gives many details about the algorithm and provides the latest stable implementation of QTempIntMiner : http://www.irisa.fr/dream/QTempIntMiner/ .
