largeVis (version 0.2.1.1)

sgdBatches: sgdBatches

Description

Calculate the default number of batches for a given number of vertices and edges.

Usage

sgdBatches(N, E = 150 * N/2)

Arguments

N

Number of vertices.

E

Number of edges.

Value

The recommended number of sgd batches.

Details

The formula used is the one used by the LargeVis reference implementation. This is substantially less than the recommendation \(E * 10000\) in the original paper.

Examples

# NOT RUN {
# Observe that increasing K has no effect on processing time
N <- 70000 # MNIST
K <- 10:250
plot(K, sgdBatches(rep(N, length(K)), N * K / 2))

# Observe that processing time scales linarly with N
N <- c(seq(from = 1, to = 10000, by = 100), seq(from = 10000, to = 10000000, by = 1000))
plot(N, sgdBatches(N))
# }
