Tuning them well is often the difference between a mediocre model and a great one.

What is Hyperparameter Tuning?
Hyperparametre yi ñooy jekkal yi nga tànn balaa ngay tàggat, lu melni tolluwaayu jàng wala dayo model bi, model bi jàngul boppam. Soo leen méngale bu baax mooy wuutale model bu baaxul ak model bu baax.
Lan mooy wuutale hyperparamètre ak parametre model buñ miin?
Poid yi (parametre yi) ñu ngi leen jàngee ci done yi ci diiru tàggat yaram. Hyperparametre yi, lu ci melni taxawaayu jàng wala limu diisaay yi, dañu leen di tànnee bu njëkk ba noppi di saytu ni tàggat bi di doxee.
