public sealed class NearestNeighborQuery.Types.Parameters : IMessage<NearestNeighborQuery.Types.Parameters>, IEquatable<NearestNeighborQuery.Types.Parameters>, IDeepCloneable<NearestNeighborQuery.Types.Parameters>, IBufferMessage, IMessage
Reference documentation and code samples for the Vertex AI v1beta1 API class NearestNeighborQuery.Types.Parameters.
Parameters that can be overrided in each query to tune query latency and
recall.
public double LeafNodesSearchFraction { get; set; }
Optional. The fraction of the number of leaves to search, set at query
time allows user to tune search performance. This value increase result
in both search accuracy and latency increase. The value should be between
0.0 and 1.0.
