Discovering Longest-lasting Correlation in Sequence Databases
- In this work, we propose several techniques such that longest-lasting correlated
subsequences can be discovered efficiently.
- Two core techniques, i.e., α-skipping technique and diamond cover index, are
proposed and their performance are evaluated thoroughly in this work. Given
reasonable space overhead, our best method (i.e., SKIP+DCI) is up to one order of
magnitude faster than the state-of-the-art adaption.
Quick-Motif: An Efficient and Scalable Framework for Exaxt Motif Discovery
- Discovering motifs in sequence databases has been receiving abundant attentions
from both database and data mining communities, where the motif is the most
correlated pair of subsequences in a sequence object.
-In this work, we propose a novel framework named Quick-Motif which adopts a twolevel approach to enable batch pruning at the outer level and enable fast correlation
calculation at the inner level. We further propose two optimization techniques for
the outer and the inner level. According to our experimental study, our method is
up to three orders of magnitude faster than the state-of-the-art methods.

A Real-time Attention Detection and Treatment System Based On HRV
- HRV (i.e., Heart Rate Variability) biofeedback therapy is widely used in the
treatment of ADHD (i.e., Attention Deficit Hyperactivity Disorder). In this work,
we captures user’s attention and design several computer games such that user’s
performance is mainly affected by his attention. As a remark, the user’s attention
is measure by his HRV.
