Creates a column containing a probability distribution either from numeric columns or a single string column. In case of numeric columns, one or more columns that contain probability values can be picked. The probability values must be non-negative and must sum up to 1.

In case of a string column, one single column can be selected. The probability distribution of the string column produces a one-hot encoding of the string column. In order to do this, the column must have a valid domain, i.e., the possible values of the column must be known. You can use a *Domain Calculator* to calculate these values if they are not present. Each of the possible values will be treated as a separate class, i.e., the number of distinct values in the string column will be the number of classes in the created probability distribution. The string value of a cell will have a probability of 1 whereby all the other possible string values of the column will have a probability of 0. The same output can be achieved by creating a probability distribution of the numeric output columns of the *One to Many* node applied to the same string column.
