I assumed that the unjudged data was written in the file unknown.txt with one case per line in previous versions.

It was hard to use it, so I made it a generator.

code:python

def get_unknowns():

logs = open(_RAW_LOGS).readlines()

for text in logs:

for case in text_to_cases(text):

yield case

The user's customization is now in user.py, and the default implementation is in default.py.

code:python

from .user import (

make_features, print_case, write, case_from_str, case_to_str, get_unknowns,

MODEL_NAME, create_model, INITIAL_DOWN_SAMPLING

)

"Where's the latest code?" so I pushed the current code for now.
