How To Set up RapidMiner library in Android Studio

edited October 2019 in Help

I am currently working on an object recognition app. I'm using Android Studio and I have created a Neural Network model on Rapid Miner Studio and saved it as PMML. I want to apply this model on a set of extracted features in Android Studio so that I can obtain a prediction (e.g: is the object a fruit/vegetable/nut?). However, I'm not able to integrate the Rapid Miner library in Android Studio. I've downloaded "rapidminer-extension-template" from https://github.com/rapidminer/rapidminer-extension-template. Is it the correct file that should be downloaded?

I have looked for a working solution for the past 4 days but I can't seem to find one.

Do I have to use the Rapid Miner library to apply the PMML model or is it possible to use something else?

    It is possible to import the PMML file in Android Studio. I had to add a library ("pmml-model-1.3.9.jar" along with the schema library: "pmml-schema-1.3.9") that supports it. Now I only have to look for the library's documentation to be able to apply the model on a set of features to obtain a prediction.

    Thanks for the help :D

    I downloaded the wrong library and found out about this only after receving an email from the library developer stating that the pmml-evaluator library had to be used instead of pmml-model.

    Ok, I'm not familiar with Android but maybe a RapidMiner Server is what you need to fill the gap. 

     

    If you're writing an Andriod app to do something, you could ping an entire RapidMiner process via a RapidMiner Server exposed REST API address. This way the app can communicate with RapidMiner and give a response.

    Thanks for your reply. The app is not supposed to require Internet connection to work.

    I just need to know:
    1. if it is possible to save a Neural Net RapidMiner model as PMML
    2. can i import this PMML file in Android Studio/Eclipse so that I can apply it on an ExampleSet to obtain a prediction

    1. There is a PMML extension but I'm not sure if you can save a neural net model in PMML format.  I would install the extension and test it out. 

    2. I can't say anything about merging PMML with Andriod Studio, assuming the NN can be saved in PMML format, you'd probably have to check if the Andriod would even support PMML.
