IMO exponential moving average suites better here. It is better to weight
the latest values rather than giveing same weight to old data.

Yes. Finding the curve after smoothing with exponentially weighted moving
average would be good. [1] is explaining something similar.

Hi Pranvan,
Thanks for the update. It seems Suho has replied in the WSO2 dev. So i hope
you are progressing without an issue.
Thanks.

Hi Lahiru and Raj,

finish the samples tomorrow. Can you please get me the document which
consists the regression functions from suho? Then I can write a regression

Hi Lahiru and Raj,
The samples that are provided with M4 pack have some library problems. Suho
suggested to use alpha pack. Shall I go ahead with alpha pack?
Thanks

Hi Lahiru and Raj,
Please comment on the following updatess.
1. I am going to implement a new method inside RuleTasksDelegator class
which has the usual prediction method *getPredictedValueForNextMinute().
*I am going to use the same name for the new method. (Method
Overloading)
2. I need some help in implementing a CustomWindowProcessor inside cep
extension package.
Please look into my work.
Thanks

Good work Pranavan.
I also think exponential moving average method will suit our requirement.
Also, it is better to use CEP 4.0.0 milestone. When we merge your changes,
CEP 4.0.0 might be released.
Tomorrow we have to start coding. Hope to see more progress!
Thanks.

Hi All,
As per my schedule I have shared the documentation on different
possibilities to improve the auto scaler algorithm[1]. Please share your
thoughts and suggestions on it. Currently I am in the process of
familiarizing with R integration of CEP(Complex Event Processor).
Sorry for the late update, since I was not well during the past few days.
