K-NN calculation for RMSE, MAE and MAPE

[norhayati]

Hi,

I tried to develop a predictive model (regression) using K-NN. I attached the workflow below.

For now, I used the formula tool to calculate the RMSE, but have trouble to calculate MAE and MAPE.

Is there any other way to have all the value? For other models such as linear regression and RF, I can use a model comparison tool to get the value.

Thank you,

Hayati

Hi @norhayati,

Are you able to upload the dataset to the thread? Or re-save the workflow and package with the data within?  When I download the workflow, the input tool references your file, but it is not attached.  Thanks!

Hi ggruccio,

I re-save the workflow. Are u able to see the data?

Hi @norhayati,

It doesn't look like the data gets saved.  You may need to go to Options-> Export Workflow->   then this will package the data inside the workflow.

Thanks!
