Dear All,
I am using a log file on on a cross validation inside an Optimize Parameters function. The cross validation run on a kNN model with performance measured by a performance (regression) function. When I use the log file to view my performance measures (absolute_error and relative_error) for each iteration the values returned is a ?.
In the log file I have selected Absoluter Error - Performance - value - Absolute Error
Thank you in advance for your help
Below is the XML Code (I think)
