RemoveOutlierTrials¶
Removes trials (instances) that have abnormally large signal values.
This node supports offline data. The node requires that the given data has an instance axis, which indexes multiple "trials", or "observations". The node calculates a measure of outlyingness for each such trial using a measure of choice, and removes trials whose measure is above a certain settable threshold (in robust standard deviations) from the data distribution. Version 1.1.0
Ports/Properties¶
data¶
Data to process.
transformation¶
Optional data transformation to apply before calculating the measure. The temporal-difference operation calculates successive differences along time.
measure¶
Measure to use. The trial norm is the root mean square (RMS) value of the whole trial, while the max-channel norm is the maximum RMS value across all channels (requires a space axis to be present).
threshold¶
Removal threshold in standard deviations.
verbose¶
Verbose output.
set_breakpoint¶
Set a breakpoint on this node. If this is enabled, your debugger (if one is attached) will trigger a breakpoint.
metadata¶
User-definable meta-data associated with the node. Usually reserved for technical purposes.
