void HClassKnn.DeserializeClassKnn( HSerializedItem serializedItemHandle )

Description🔗

deserialize_class_knnDeserializeClassKnn deserializes a k-NN classifier (k-NN) (including its training samples), that was serialized by serialize_class_knnSerializeClassKnn (see fwrite_serialized_itemFwriteSerializedItem for an introduction of the basic principle of serialization). The serialized k-NN classifier is defined by the handle SerializedItemHandleserializedItemHandleserialized_item_handle. The deserialized values are stored in an automatically created k-NN classifier with the handle KNNHandleKNNHandleknnhandle.

Execution information🔗

Execution information

  • Multithreading type: reentrant (runs in parallel with non-exclusive operators).

  • Multithreading scope: global (may be called from any thread).

  • Processed without parallelization.

Parameters🔗

SerializedItemHandleserializedItemHandleserialized_item_handle (input_control) serialized_item → (handle)HTuple (HHandle)HSerializedItem, HTuple (IntPtr)HHandleHtuple (handle)

Handle of the serialized item.

KNNHandleKNNHandleknnhandle (output_control) class_knn → (handle)HTuple (HHandle)HClassKnn, HTuple (IntPtr)HHandleHtuple (handle)

Handle of the k-NN classifier.

Result🔗

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