nlp_embeddings_finisher | R Documentation |
Spark ML transformer that is designed to deal with embedding annotators: WordEmbeddings, BertEmbeddings, SentenceEmbeddingd, and ChunkEmbeddings. By using EmbeddingsFinisher you can easily transform your embeddings into array of floats or Vectors which are compatible with Spark ML functions such as LDA, K-mean, Random Forest classifier or any other functions that require featureCol. See https://nlp.johnsnowlabs.com/docs/en/transformers#embeddingsfinisher
nlp_embeddings_finisher( x, input_cols, output_cols, clean_annotations = NULL, output_as_vector = NULL, uid = random_string("embeddings_finisher_") )
x |
A |
input_cols |
Input columns. String array. |
output_cols |
Output columns. String array. |
clean_annotations |
Whether to remove and cleanup the rest of the annotators (columns) |
output_as_vector |
if enabled, it will output the embeddings as Vectors instead of arrays |
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.
