... occurring simultaneously. There has been much work on clustering time-series data and clustering can be done based on either similar- ity of expression magnitude or the shape of expression dynamics. Clustering methods include ... x g . 2.3. Extraction of Shape Information and Time Scaling. To extract shape information of time-varying gene expression, the de...

The use of lattice QMF representation for converting the constrained optimization ... spread of wavelet in time. This definition of time-duration gives a measure of time localization of the wavelet [25]. Now, the above definition of time duration is used for selec...
