input:8 pieces of gps location latitude data, with length 52, 44,39,72, 41, 40, 164, 189.
program is
patterns = pyfpgrowth.find_frequent_patterns(transactions, 2)
rules = pyfpgrowth.generate_association_rules(patterns, 0.7)
It used out 32GB memory, run in single thread, lasting 16 hours and still can not output , then I kill the process. Could anyone tell me how to do? I would appreciate for your valuable suggestion.
