"- commitując rozwiązanie proszę również umieścić rozwiązanie w pliku /run.py (czyli na szczycie katalogu). Można przekonwertować jupyter do pliku python przez File → Download as → Python. Rozwiązanie nie musi być w pythonie, może być w innym języku.\n",

"Uwagi:\n",
"\n",
"- warto wymyślić jakąś metodę wygładazania, bez tego może być bardzo kiepski wynik\n",
"- nie trzeba korzystać z całego zbioru trenującego\n",
"- zadanie to 70 punktów, za najlepsze rozwiązanie w swojej grupie przyznaję dodatkowo 40 punktów\n",
"- punkty będą przyznane na gonito\n",
"- warto monitorować RAM, próbować z różnym vocab_size, można skorzystać z pythonowego Counter\n",
"- warto sobie zrobić dodatkowo model unigramowy w ramach ćwiczenia"
