From multiInstanceLearning package version 1.0.3 for Weka >= 3.7.2.

Options

The table below describes the options available for MITI.

Option	Description
attributesToSplit	The number of randomly chosen attributes to consider for splitting.
b	Whether to use bag-based statistics for estimates of proportion.
ba	Multiplier for count influence of a bag based on the number of its instances.
debug	If set to true, classifier may output additional info to the console.
k	The value used in the tozero() method.
l	Whether to scale based on the number of instances.
seed	The random number seed to be used.
