nlp_assertion_logreg( x, input_cols, output_col, label_column = NULL, max_iter = NULL, reg = NULL, enet = NULL, before = NULL, after = NULL, start_col = NULL, end_col = NULL, lazy_annotator = NULL, uid = random_string("assertion_logreg_") )
x |
A |
input_cols |
Input columns. String array. |
output_col |
Output column. String. |
label_column |
Column with one label per document |
max_iter |
Max number of iterations for algorithm |
reg |
Regularization parameter |
enet |
Elastic net parameter |
before |
Amount of tokens from the context before the target |
after |
Amount of tokens from the context after the target |
start_col |
Column that contains the token number for the start of the target |
end_col |
Column that contains the token number for the end of the target |
lazy_annotator |
a Param in Annotators that allows them to stand idle in the Pipeline and do nothing. Can be called by other Annotators in a RecursivePipeline |
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.
