H2O PCA

This node applies a Principal Component Analysis (PCA) model using H2O.

Options

General Settings

Dimensions to reduce to

Specify the rank of matrix approximation (the dimension of the principal components). Note that the dimension cannot be larger than the dimension of the input data (k).

Column selection

Select columns used for model training.

Ignore constant columns

Select to ignore constant columns.

Algorithm Settings

Transformation method

Specify the transformation method for the training data (None, Standardize, Normalize, Demean, or Descale) (transform).

PCA method

Specify the algorithm to use for computing the principal components (pca_method).

Number of max iterations

Specify the number of training iterations (max_iterations).

Use all factor levels

Specify whether to use all factor levels in the possible set of predictors (use_all_factor_levels).

Impute missing values

Specify whether to impute missing entries with the column mean value (impute_missing). Note that if this option is set to false, any rows with missing values will be removed.

Advanced Settings

Max runtime in seconds

Maximum allowed runtime in seconds for model training (max_runtime_secs).

Use static random seed

Select to use static seed for randomization.
