h2o.reconstruct | R Documentation |
Reconstruct the training data and impute missing values from the H2O GLRM model by computing the matrix product of X and Y, and transforming back to the original feature space by minimizing each column's loss function.
h2o.reconstruct(object, data, reverse_transform = FALSE)
object |
An H2ODimReductionModel object that represents the model to be used for reconstruction. |
data |
An H2OFrame object representing the training data for the H2O GLRM model. Used to set the domain of each column in the reconstructed frame. |
reverse_transform |
(Optional) A logical value indicating whether to reverse the transformation from model-building by re-scaling columns and adding back the offset to each column of the reconstructed frame. |
Returns an H2OFrame object containing the approximate reconstruction of the training data;
h2o.glrm
for making an H2ODimReductionModel.
