"Plot all predicitons in SlidingWindowValidation"

韦塞尔

Dear All,

I wish to plot all my predictions made in my SlidingWindowValidation.
Currently I can only plot the predictions made in the FIRST iteration of the SlidingWindowValidation!

To plot the FIRST iteration I have to:
Set a breakpoint in RegressionPerformance.
Click on:
DataTable Tab.
PlotView
Plotter: Series
Index Dimension: Date
Plot series: [single_price, prediction(single_price)]
(A lot of work, would be nice if this could be automated)


现在我如何阴谋slidi预测ng my SlidingWindowValidation.
I figured on each iteration I could write the datasets the comes out of ModelApplier to a new dataset.
The problem is CSVExampleSetWriter overwrites the old results.csv on each iteration!
Is there any way to make it append, instead of overwrite?

Regards,

Wessel

Yes I know this is not the way to predict single_price.
But this should be the way to evaluate the performance of the prediction.

Hi Wessel,

Use the much unloved process log and his chums, like this...

Weird, can't get it to work.
My version is now only logging the last example, of each iteration...

I think this is because your version only works with

If I change it to 350, it only logs the first 1 in this window.

Hi,
just an idea, but if you want to merge all results, the following process variation could give you an impression of another way:

I did not really test the process, so the setup might fail. But the way should be clear...

I think it works like this:
Although I don't understand why the 2 RegressionPerformance don't give the same results.
21 vs 22...
