HOW TO APPLY DBScan & Deep Learning on Classification Model

kimchi · February 2019

Hi,

I'm pretty new with RapidMiner and wondering how to apply DBScan & Deep Learning on a classification model.
My data is binomial. Do I need to use binomial or integer values for these methods?

Hi @kimchi

Deep learning in RM can be done using a deep learning extension that is available in the market place (Menu Bar --> Extensions --> Market Place). You need to install that.

If you are just trying to apply deep learning with fully connected layers you can use the deep learning operator that comes with RM, but if you are looking to apply CNN, LSTM then you need to have deep learning extension.

If you install a deep learning extension from market place it comes with examples. You can see below screenshots for understanding. I also added code for a deep learning operator which is a multilayer feed forward neural network.
