DATA INPUT FORMAT

KNIME Analytics Platform
1

I am working on a research project of comparing Discrete choice model (DCM) with Machine learning model with Prof Vithal Rao from Cornell University in US.

I need your help in data input to ML Models.

The way data is available for DCM from various surveys are that each customer has multiple records for the different choices he has exercised .
For each choice the attribute levels will be different.

So say for customer no 1 out of the three choices he will respond that response to Question 2 will be choice Number 1 , Response to Q1 will be choice 2 , Response to Q3 will be Choice 3 .

If I recall for ML Models it expects a single record for each customer.

I am planning to use KNIME for this work.

Will appreciate if you can suggest how to set up data for this type of analysis.

Hi @Chandrasekhar -

I believe my colleague Stefan emailed you to continue the discussion about possible workarounds. Perhaps I can get a summary of that for the benefit others here. I’ll check. :slight_smile:
