balancenode properties
The Balance node corrects imbalances in a dataset, so it conforms to a specified condition. The
balancing directive adjusts the proportion of records where a condition is true by the factor
specified.
Example
node = stream.create("balance", "My node")
node.setPropertyValue("training_data_only", True)
node.setPropertyValue("directives", [[1.3, "Age > 60"], [1.5, "Na > 0.5"]])

Structured property to balance proportion of field values based on number specified. | |
training_data_only
|
flag | Specifies that only training data should be balanced. If no partition field is present in the stream, then this option is ignored. |
This node property uses the format:
[[ number, string ] \ [ number, string] \ ... [number, string ]].
Note: If strings (using double quotation marks) are embedded in the expression, they must be
preceded by the escape character
" \ ". The " \ " character is
also the line continuation character, which you can use to align the arguments for clarity.
