Sliding Window GP

[mkommend]

For various data analysis tasks it would be beneficial to have a sliding window modeling approach similar to the implementation in HL 2.0. Instead of implementing this as an algorithm, it can be implemented as analyzers that shift the window over the training partition and thus all other features of HL 3.3 can be used.

The only modified classes which must be reviewed are in an extra folder SlidingWindow in HL.Problems.DataAnalysis.Symbolic and the SlidingWindowDataView. To ease the testing and to have some kind of template for further algorithms, three samples are provided in the folder of the solution.

Observations:

• for a users it is surprising the the GA stops before the max. number of generations is reached (this happens because the algorithm seemingly stops when the sliding window is empty?).
• large number of parameters makes it unnecessarily complicated to configure the sliding window behavior (e.g. are "generation interval start" and "initial sliding window" really useful?)
• icon of "sliding window data" result does not indicate that there is a line chart view available
• I think it is sufficient to only have the "sliding window data" result in the results collection. The "Sliding Window" result should be removed.
• "Sliding Window Visualizer" is an unconventional name for an analyzer (should be discussed)
• Why is there an algorithm parameter that allows to set parameters for the "sliding window" (only "generational sliding window analyzer" is allowed) and an additional analyzer where I can set the same parameters? What happens if I use the "offspring selection sliding window analyzer" instead?

I have not yet looked at the source in detail.
