Mahout-18 is about the description of physical data instances. Here I refer to the model representation. For example, with Naieve Bayes, we may need store the number of instances of (Class = 1) and (Class = 0), as well as the cases of ( Class=1| X_i = 0 ). With this information, we can re-store the model for updating or scoring purpose.
Another case is the Bayesian Network. We need store the graph structure as well as the conditional probability table if we want to re-install it somewhere.

Seems like that is a similar thing, trying to define common I/O, or am I misinterpreting? > Embrace interoperability with other softwares > --------------------------------------------- > > Key: MAHOUT-18 > URL: https://issues.apache.org/jira/browse/MAHOUT-18 > Project: Mahout > Issue Type: New JIRA Project > Reporter: Shunkai Fu > Priority: Minor > > This is an open issue. It is related with all possible components existing or to born in the future. > ML or DM models normally have two phases: training and scoring (or predicting). If we agree "updating" is an independent one, we will have 3 phases. > There are many softwares about ML/DM outside. We want the users of Mahout be able to import models got built from other software here, update them and/or use them for scoring. To achieve this goal, we need to recognize the commonly used formats. > Besides, users may choose Mahout because Mahout is speedy in learning. After a model is ready, they may export the model trained, view it with some visualization tool, or import it into other software or application for scoring (or predicting). In this case, exporting into widely recognized format is expected. > Finally, I want to say that the importing and exporting will not influence the ongoing projects, so developers of other components need not worry about this. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
