Density Updater

Updates a density model. Note that the model can only be updated with the data it was initialized with in the corresponding initializer node ( Potential Density Initializer or Graph Density Initializer ). The update is performed by reducing the densities in the neighborhoods of all newly labeled data points according to the used density estimation algorithm.

Input ports

1. Type: Density Scorer Model
   Density Scorer Model
   Density scorer model created with either the Potential Density Initializer or the Graph Density Initializer node.
2. Type: Table
   Update Data
   Table containing rows in whose neighborhoods the density in the model needs to be reduced. In an active learning setting these would be the rows that were freshly labeled by the user. (optional)

Output ports

1. Type: Density Scorer Model
   Updated Density Scorer Model
   The updated model i.e. decreased densities in the neighborhood of rows in the input table.
