Reducing example set using average
Attached to this is the image of my example set, it shows i have 683 examples and 343 regular attributes. I would like to reduce the examples set down to 100 examples and keep the number of attributes, with each of the new example is the average of a group of old example. For example, 683/100 = 6.83, so each new example will be the average for 6 of the old example. I know it is similar to moving average, but with moving average operator can only select 1 column and the result of that operator is just the average continuously. I also plan to use this on different example set and each of them have varied size from 500 examples to 2000 examples.
