deserialize_class_knndeserialize_class_knnDeserializeClassKnndeserialize_class_knnDeserializeClassKnnDeserializeClassKnn (Operator)

Name

deserialize_class_knndeserialize_class_knnDeserializeClassKnndeserialize_class_knnDeserializeClassKnnDeserializeClassKnn — Deserialize a serialized k-NN classifier.

Signature

deserialize_class_knn( : : SerializedItemHandle : KNNHandle)

Description

deserialize_class_knndeserialize_class_knnDeserializeClassKnndeserialize_class_knnDeserializeClassKnnDeserializeClassKnn deserializes a k-NN classifier (k-NN) (including its training samples), that was serialized by serialize_class_knnserialize_class_knnSerializeClassKnnserialize_class_knnSerializeClassKnnSerializeClassKnn (see fwrite_serialized_itemfwrite_serialized_itemFwriteSerializedItemfwrite_serialized_itemFwriteSerializedItemFwriteSerializedItem for an introduction of the basic principle of serialization). The serialized k-NN classifier is defined by the handle SerializedItemHandleSerializedItemHandleSerializedItemHandleSerializedItemHandleSerializedItemHandleserializedItemHandle. The deserialized values are stored in an automatically created k-NN classifier with the handle KNNHandleKNNHandleKNNHandleKNNHandleKNNHandleKNNHandle.

Parallelization

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

Parameters

SerializedItemHandleSerializedItemHandleSerializedItemHandleSerializedItemHandleSerializedItemHandleserializedItemHandle (input_control) serialized_item → (integer)

Handle of the serialized item.

KNNHandleKNNHandleKNNHandleKNNHandleKNNHandleKNNHandle (output_control) class_knn → (integer)

Handle of the k-NN classifier.

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