KNIME WEKA nodes (3.7) version 4.2.0.v202007031307 by KNIME AG, Zurich, Switzerland
Cluster data using the sequential information bottleneck algorithm. Note: only hard clustering scheme is supported
sIB assign for each instance the cluster that have the minimum cost/distance to the instance.The trade-off beta is set to infinite so 1/beta is zero.

(based on WEKA 3.7)
For further options, click the 'More' - button in the dialog.
All weka dialogs have a panel where you can specify classifier-specific parameters.
I: maximum number of iterations (default 100).
M: minimum number of changes in a single iteration (default 0).
N: number of clusters. (default 2).
R: number of restarts. (default 5).
U: set not to normalize the data (default true).
V: set to output debug info (default false).
S: Random number seed. (default 1)
The Preliminary Attribute Check tests the underlying classifier against the DataTable specification at the inport of the node. Columns that are compatible with the classifier are marked with a green 'ok'. Columns which are potentially not compatible are assigned a red error message.
Important: If a column is marked as 'incompatible', it does not necessarily mean that the classifier cannot be executed! Sometimes, the error message 'Cannot handle String class' simply means that no nominal values are available (yet). This may change during execution of the predecessor nodes.
Capabilities: [Numeric attributes, No class] Dependencies:  min # Instance: 1
It shows the command line options according to the current classifier configuration and mainly serves to support the node's configuration via flow variables.
