Calculate Memory-Aware Sample Size Limit (Internal)

Source: R/career_clustering.R
dot-calculate_memory_aware_limit.Rd

Determines the maximum sample size for distance matrix calculations based on available system memory. This prevents memory exhaustion when computing silhouette scores or other metrics requiring O(n²) distance matrices.

Usage

.calculate_memory_aware_limit(
  memory_fraction = 0.33,
  p = 10,
  method = c("clustering", "silhouette"),
  verbose = FALSE
)

Arguments

memory_fraction

Numeric. Fraction of available RAM to use (default 0.33 = 33%)

p

Integer. Number of features (for overhead calculation)

method

Character. Purpose: "clustering" (default) or "silhouette" (stricter limits)

verbose

Logical. Print memory info?

Value

Integer. Maximum safe sample size for distance matrix calculations
