### Description
Cylinder bands UCI dataset - Process delays known as cylinder banding in rotogravure printing were substantially mitigated using control rules discovered by decision tree induction.
### Attribute Information
There are 40 attributes for 540 observations, including the class: 20 are numeric and 20 are nominal.
There are missing values in 302 of the instances.

Notes:
* cylinder number is an identifier and should be ignored when modeling the data
* data set consists of 540 observations. UCI explanation states 541, which is wrong.
