DTW related issues

[sankalpg]

• Should DTW be used with some local constraints or not?
• Should we use DTW subsequence version or point to point version. If p2p then how do we handle tempo variations. Should we have multiple subsequences with linear stretching?
• Should we use weights for insertion and deletion?
• Should we path normalize distances? In which case lowerbounds might not work
• Should we have early abandoning enabled or disabled
