Assigning Weights

11/25/2014 1:34 AM

Hi..

I have data which has many setpoint changes. I have to calculate the oscillation index for the data. I have calculated OSI for the different Setpoint changes differently and i want to know how to proceed with it. I can take the mean of the values/ max of the value. One more method is assigning weight according to the number of data points is also possible solution to this i think. I need some help with this and will neural network help in this problem??

All depends on what you are actually trying to achieve.

i wanted to know which method will work fine.. According to me assigning according to the data length will be good because we are calculating the index based on the data length (of a Setpoint change) only. But i dont know how to apply neural networks here. How to assign weights to this problem.

Like this: http://en.wikipedia.org/wiki/Artificial_neural_network

The method should be chosen by the desired outcome.

Not sure how the setpoint works in this.

There might be vendors out there with available software to do what you need to do.
