One Hot Encoder Advanced Transform Node Details
+++++++++++++++


The One Hot Encoder Advanced Transform Node is used to map a column of label indices to a column of binary vectors, with at most a single one-value. It takes in an input DataFrame and transforms it to another DataFrame. It also takes in a fit model as input, which is typically the output of a previous One Hot Encoder Advanced Estimator Node.

The transformed DataFrame contains a new column with the mapping of a column of label indices to a column of binary vectors, with at most a single one-value.



Input Parameters

FIT MODEL : The output of a previous One Hot Encoder Advanced Estimator Node, which contains the information about the column to be encoded and the specifications for the encoding.

One Hot Encoder Advanced Transform Node Example
+++++++++++++++


Consider the following example, where we have a DataFrame with a column 'color' containing categorical values. We use a One Hot Encoder Advanced Estimator Node to specify the column to be encoded and the specifications for the encoding, creating a fit model. Then, we use the One Hot Encoder Advanced Transform Node to transform the 'color' column using the fit model.


Input DataFrame:


id color

1 red

2 green

3 blue


Output


id color color_encoded

1 red [1.0, 0.0, 0.0]

2 green [0.0, 1.0, 0.0]

3 blue [0.0, 0.0, 1.0]

In this example, the input column is 'color' and the output column is 'color_encoded'. The fit model is created using the One Hot Encoder Advanced Estimator Node. The One Hot Encoder Advanced Transform Node uses this fit model to transform the 'color' column, creating a new column 'color_encoded' with the binary vectors of the encoded values.
