PDC

Efficient phase diagram construction based on uncertainty sampling

USAGE

• The following command outputs the next point in 'next_point.csv' without parameter constraint.
  • python PDC_sampler.py data.csv --estimation [Estimation method] --sampling [Sampling method]
  • Estimation method: LP or LS
  • Sampling method: LC, MS, EA, or RS
• The following command outputs the next point in 'next_point.csv' with parameter constraint.
  • python PDC_sampler.py data.csv --estimation [Estimation method] --sampling [Sampling method] --parameter_constraint --prev_point '20, 100'
• The following command outputs the multiple next points in 'next_point.csv' without parameter constraint.
  • python PDC_sampler.py data.csv --estimation [Estimation method] --sampling [Sampling method] --multi_method [Multiple method] --multi_num [Number of suggestions] --NE_k [k]
  • Estimation method: LP or LS
  • Sampling method: LC, MS, EA, or RS
  • Multiple method: OU or NE (OU: Only US ranking, NE: Neighobr Exclusion)
  • Number of suggestions: integer
  • k: k value in neighbor exclusion
