Time series pattern mining (TSPM) finds correlations or dependencies in same series or in multiple time series. When the numerous instances of multiple time series data are associated with different quantitative attributes, they form a multiple multi-dimensional framework. In this paper, we consider real-life time series data of muscular activities of human participants obtained from multiple Electromyogram (EMG) sensors and discover patterns in these EMG data streams. Each EMG data stream is associated with quantitative attributes such as energy of the signal and onset time which are required to be mined along with EMG time series patterns. We propose a two-stage approach for this purpose: in the first stage, our emphasis is on discovering frequent patterns in multiple time series by doing sequential mining across time slices. And in the next stage, we focus on the quantitative attributes of only those time series that are present in the patterns discovered in the first stage. Our ev...
