Fwd: Can The Classification Engine Handle Multiple Sets of Independent Data

[Dipen Patel <pa...@gmail.com>]

Hello,

I am interested in using predictionio's classification engine. Would the
classification be able to accurately classify if it had data consisting of
multiple independent sets of data. For instance, if a training data set
accepted the id corresponding to a movie director, the amount of money
spent filming the movie, and the views the movie received, could one
classification engine be able to predict the amount of views a movie would
be likely to receive if the training data had included data of different
directors? My concern is that not having a separate classification engine
instance for each director will cause the single classification engine to
mistakenly use data from other directors.

Thanks.

 you can filter the data you need by using PEventStore API or modifying the
DataSource.scala. Then train different engine instance with different
configuration.

Hi,

If you are using the stock classification engine template, your easiest way
out would be to use multiple engine servers. If that is not desired, you
could modify the engine template to handle different data sets
independently.
