Naive DTW is up and running.

So I've made it through the Wicket data models and ended up with a lot of a spaghetti code for this version while refactoring telemetry/trajectory code and my previous DTW code out of trajectory. Look at the amount of debug information I am printing, (haha!):




Voila:

The trajectory convenience in action, "the base page":



If you can find a little "Do DTW analysis" button right to the "Get Chart" button and click it this is what you'll see:



Basically along with the streams statistics at the left you can see the sequence of three plots:
1) the original trajectory/telemetry chart,
2) the normalized timeseries which have Zeroes instead of NA... (i know it'll work for DevTime chart, but I need to figure out what to do with other streams.)
3) the DTW-treated normalized time series.

Nice... However I found that it is somehow different from the R implementation I am using as the reference:



Right now I am debugging what is going wrong with my Dynamic Programming implementation and meanwhile trying to clean-up my code from repeating myself. While debugging, I found an awesome new feature in the Excel 2007: Conditional formatting, just look at this beautiful heat maps:



Bottom line for this week progress is that Naive DTW is implemented and embedded in the ProjectBrowser. You would ask, "So what about "similarity"?", well, I have a code to calculate the Euclidean distances between time series too, and have numbers calculated, just need to find a place where to render those at UI panels.

Next week plan is: code cleanup and optimization, implementation of the R Charting instead of GoogleCharts.
