x |
A |
input_cols |
Input columns. String array. |
output_col |
Output column. String. |
label_col |
name of the column containing the category labels |
batch_size |
Batch size for training |
max_epochs |
Maximum number of epochs to train |
lr |
Initial learning rate |
dropout |
Dropout coefficient |
validation_split |
proportion of data to split off for validation |
verbose |
Verbosity level |
enable_output_logs |
boolean to enable/disable output logs |
lazy_annotator |
boolean |
output_logs_path |
path to put the output logs |
uid |
A character string used to uniquely identify the ML estimator. |
The object returned depends on the class of x
.
spark_connection
: When x
is a spark_connection
, the function returns an instance of a ml_estimator
object. The object contains a pointer to
a Spark Estimator
object and can be used to compose
Pipeline
objects.
ml_pipeline
: When x
is a ml_pipeline
, the function returns a ml_pipeline
with
the NLP estimator appended to the pipeline.
tbl_spark
: When x
is a tbl_spark
, an estimator is constructed then
immediately fit with the input tbl_spark
, returning an NLP model.
