6th challenge

I'll update it if time allows
No optimization yet.
Made this just for baseline

Context
…TF, IDF, 2 gram for features

…Negative Down Sampling -> Not needed in this challenge since imbalace is not so much

…Feature selection by GA (not confirmed if this is the best). I used it just for fun

…only 3000 samples are used
