How to achieve good clustering results in subsequence time series clustering with DBSCAN?
I want to find patterns in a time series and use clustering for that. Before I cluster, I create subsequences from the time series using a sliding window approach. (STS-clustering)
So far I have tried ...

Is clustering subsequences of time-series still meaningless with unsupervised learning?
In the paper "Clustering of Time Series Subsequences Is Meaningless" Keoh et al. claim that breaking a time-series into chunks (sometimes called lags) of fixed-size using the rolling window method ...
