Need advise to improve decision tree output

Output Accuracy StatisticsHi,

I am beginner using KNIME. I am trying to predict a status of cow based on the accelerometer data. I have used decision trees in my model. However, the accuracy is shown as .22. Any advise on how to improve this? I would like to know if the data set is not complete.

Attaching the screenshot of the output. Many thanks, Bharadwaj


did you consider using the tree ensemble nodes instead? Maybe the underlying model is too complex for a decision tree.

Best regards, Iris
