TF - IDF
Жил-был в лесу заяц. Все зайцы были как зайцы: летом серые,
зимой белые. А этот и зимой и летом был одним цветом. И цвет этот
был ни белый, ни серый, а просто грязный, потому что заяц никогда
не умывался. Шел как-то он по тропинке, а навстречу ему лиса.- Ты
кто? – спрашивает лиса.- Заяц, - ответил заяц.- Не может быть, -
замотала головой лиса. – Я никогда таких зайцев не видела, таких
страшных не бывает! Может быть ты еж?- Почему? – удивился заяц.-
Потому что на тебе солома старая, и шерсть вся свалялась, на
иголки стала похожа. Заяц обиделся, но решил, что умываться не
будет.
TF = 6 / 100 =
0.06IDF = Log (10 000 000/ 1000) = 4
TF-IDF = 0.06 * 4 = 0.24

CHALLENGES
• IF NOBODY CHECK RESULT – IT DEGRADATE
• LEARNING ALWAYS NEEDS TRAINER
• IF MACHINE ERROR APPEARS - ERROR INFLUENCE GROWTHS
• NEED TO FLUSH TRAINING
