@brief Supplemental parameters to build Vamana Index

graph_degree: Maximum degree of graph; corresponds to the R parameter of Vamana algorithm in the literature. visited_size: Maximum number of visited nodes per search during Vamana algorithm. Loosely corresponds to the L parameter in the literature. vamana_iters: The number of times all vectors are inserted into the graph. If > 1, all vectors are re-inserted to improve graph quality. max_fraction: The maximum batch size is this fraction of the total dataset size. Larger gives faster build but lower graph quality. alpha: Used to determine how aggressive the pruning will be.

Fields

metric: cuvsDistanceType

Distance type.

graph_degree: u32

Maximum degree of output graph corresponds to the R parameter in the original Vamana literature.

visited_size: u32

Maximum number of visited nodes per search corresponds to the L parameter in the Vamana literature

vamana_iters: f32

Number of Vamana vector insertion iterations (each iteration inserts all vectors).

alpha: f32

Alpha for pruning parameter

max_fraction: f32

Maximum fraction of dataset inserted per batch. * Larger max batch decreases graph quality, but improves speed

batch_base: f32

Base of growth rate of batch sizes

queue_size: u32

Size of candidate queue structure - should be (2^x)-1

reverse_batchsize: u32

Max batchsize of reverse edge processing (reduces memory footprint)
