K-nearest neighbors

  • Siz tasniflash tizimini yaratishni o'rganasiz k-eng yaqin qo'shnilar algoritmi.

  • Xususiyatlarni chiqarish haqida bilib olasiz.

  • Siz regressiya haqida bilib olasiz: raqamni bashorat qilish, masalan, ertaga birja qiymati yoki foydalanuvchi filmdan qanchalik zavq olishi.

  • Siz k-yaqin qo'shnilarning foydalanish holatlari va cheklovlari haqida bilib olasiz.
