Maciej Grzenda commented on SAMOA-68:
-------------------------------------
In a recent commit [SAMOA-68: fix and extensions to prediction
file|https://github.com/apache/incubator-samoa/pull/61/commits/6031bf7a3a362553dafbd6cc0b8ab847269e7e61]
we added test templates for testing -h option (frequency of prediction dump to
file) and added the ability to dump predictions for last instance (thanks
Nicolas for the comments noticing this)
> Saving true and predicted labels to file

> Key: SAMOA-68
> URL: https://issues.apache.org/jira/browse/SAMOA-68
> Project: SAMOA
> Issue Type: New Feature
> Components: SAMOA-API
> Reporter: Maciej Grzenda
> Labels: features
>
> Currently PrequentialEvaluation task supports dumpFile option. With this
> option model performance can be saved to a file. However, in some cases it
> would be good to save also individual predictions made by a model. This is
> useful for model debugging and method development.
> This could be also used to visualize model output, calculate custom
> performance indicators (e.g. model accuracy for instances of a certain class
> or sharing the same feature value). Such saving of model output (if done)
> should be made for every instance. Hence, a new option making it possible to
> dump predictions to a separate file seems justified. For classification, it
> should include votes made for individual classes, if available.
