名称
deserialize_class_knnT_deserialize_class_knnDeserializeClassKnnDeserializeClassKnndeserialize_class_knn — 反序列化一个序列化的 k-NN分类器。

描述
deserialize_class_knndeserialize_class_knnDeserializeClassKnnDeserializeClassKnnDeserializeClassKnndeserialize_class_knn deserializes a k-NN classifier (k-NN)
(including its training samples), that was serialized
by serialize_class_knnserialize_class_knnSerializeClassKnnSerializeClassKnnSerializeClassKnnserialize_class_knn (see fwrite_serialized_itemfwrite_serialized_itemFwriteSerializedItemFwriteSerializedItemFwriteSerializedItemfwrite_serialized_item for an
introduction of the basic principle of serialization). The
serialized k-NN classifier is defined by the handle SerializedItemHandleSerializedItemHandleSerializedItemHandleSerializedItemHandleserializedItemHandleserialized_item_handle. The deserialized values are stored in an
automatically created k-NN classifier with the handle KNNHandleKNNHandleKNNHandleKNNHandleKNNHandleknnhandle。
执行信息
- 多线程类型：可重入（与非独占算子并行运行）。
- 多线程作用域：全局（可从任何线程调用）。
- 未采用并行化处理。
