Workflow Polynomial regression in Rapdminer 9.5

Hello all,

对不起,也许我有两个简单的问题that I still can't answer after two weeks of searching.

1. How can I use linear regression and polynomial regressions both in the workflow with root mean squared error as a metric?
2. I have worked them out separately, see the workflow in the attachment, but I get two completely different results? I think that the polynomial, in particular, is rather strange to interpret. I do exactly the same workflow as the linear regression both with factor 1 and with factor 2. I have read on this community that it must be factor 2?

I hope you will help me with this how I can solve this.

Thanks in advance!

Greetings,

Bernie

    嗨@Brendasorry no one has chimed in here. Let me see if I can help...

    1. do you want to use polynomial and linear in two separate models, or as one ensemble model? The approach is different depending on what you want to do.
    2. it's hard to tell why you're getting different results just by those screenshots. Can you please post your data set and your process XMLs so we can replicate what you're doing?
