You can use the PartitionedMultiFilter for that: https://weka.sourceforge.io/doc.dev/weka/filters/unsupervised/attribute/PartitionedMultiFilter.html This meta-filter allows you to define attribute ranges and their associated filters. Just specify the correct range of attributes that you want to normalize and use Normalize as the filter. By default, all attributes not covered by the ranges will just be copied across.
