Instance Attribute Details

#approximate_neighbor_count ⇒ Fixnum

The number of neighbors to find via approximate search before exact reordering is performed. If not set, the default value from scam config is used; if set, this value must be > 0. Corresponds to the JSON property approximateNeighborCount

Returns:

  • (Fixnum)

  @approximate_neighbor_count
end

#datapoint ⇒ Google::Apis::AiplatformV1beta1::GoogleCloudAiplatformV1beta1IndexDatapoint

A datapoint of Index. Corresponds to the JSON property datapoint

Returns:

def datapoint
  @datapoint
end

#fraction_leaf_nodes_to_search_override ⇒ Float

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. If not set or set to 0.0, query uses the default value specified in NearestNeighborSearchConfig.TreeAHConfig.fraction_leaf_nodes_to_search. Corresponds to the JSON property fractionLeafNodesToSearchOverride

Returns:

  • (Float)

  @fraction_leaf_nodes_to_search_override
end

#neighbor_count ⇒ Fixnum

The number of nearest neighbors to be retrieved from database for each query. If not set, will use the default from the service configuration (https://cloud. google.com/vertex-ai/docs/matching-engine/configuring-indexes#nearest-neighbor- search-config). Corresponds to the JSON property neighborCount

Returns:

  • (Fixnum)

  @neighbor_count
end

#per_crowding_attribute_neighbor_count ⇒ Fixnum

Crowding is a constraint on a neighbor list produced by nearest neighbor search requiring that no more than some value k' of the k neighbors returned have the same value of crowding_attribute. It's used for improving result diversity. This field is the maximum number of matches with the same crowding tag. Corresponds to the JSON property perCrowdingAttributeNeighborCount

Returns:

  • (Fixnum)

#rrf ⇒ Google::Apis::AiplatformV1beta1::GoogleCloudAiplatformV1beta1FindNeighborsRequestQueryRrf

Parameters for RRF algorithm that combines search results. Corresponds to the JSON property rrf

Returns:
