serialize_class_knnserialize_class_knnSerializeClassKnnserialize_class_knnSerializeClassKnnSerializeClassKnn (Operator)

Name

serialize_class_knnserialize_class_knnSerializeClassKnnserialize_class_knnSerializeClassKnnSerializeClassKnn — Serialize a k-NN classifier.

Signature

serialize_class_knn( : : KNNHandle : SerializedItemHandle)

Description

serialize_class_knnserialize_class_knnSerializeClassKnnserialize_class_knnSerializeClassKnnSerializeClassKnn serializes a k-NN classifier (k-NN) and its stored training samples (see fwrite_serialized_itemfwrite_serialized_itemFwriteSerializedItemfwrite_serialized_itemFwriteSerializedItemFwriteSerializedItem for an introduction of the basic principle of serialization). The same data that is written in a file by write_class_knnwrite_class_knnWriteClassKnnwrite_class_knnWriteClassKnnWriteClassKnn is converted to a serialized item. The k-NN classifier is defined by the handle KNNHandleKNNHandleKNNHandleKNNHandleKNNHandleKNNHandle. The serialized k-NN classifier is returned by the handle SerializedItemHandleSerializedItemHandleSerializedItemHandleSerializedItemHandleSerializedItemHandleserializedItemHandle and can be deserialized by deserialize_class_knndeserialize_class_knnDeserializeClassKnndeserialize_class_knnDeserializeClassKnnDeserializeClassKnn.

Parallelization

Multithreading type: reentrant (runs in parallel with non-exclusive operators).
Multithreading scope: global (may be called from any thread).
Processed without parallelization.

Parameters

KNNHandleKNNHandleKNNHandleKNNHandleKNNHandleKNNHandle (input_control) class_knn → (integer)

Handle of the k-NN classifier.

SerializedItemHandleSerializedItemHandleSerializedItemHandleSerializedItemHandleSerializedItemHandleserializedItemHandle (output_control) serialized_item → (integer)

Handle of the serialized item.

If the parameters are valid, the operator serialize_class_knnserialize_class_knnSerializeClassKnnserialize_class_knnSerializeClassKnnSerializeClassKnn returns the value 2 (H_MSG_TRUE). If necessary, an exception is raised.
