Đọc is a metric in a normed vector space. Minkowski distance is used for distance similarity of vector. Given two or more vectors, find distance similarity of these vectors.

Bàn luận

Khoảng cách Minkowski là một số liệu trong không gian vectơ được định mức. Khoảng cách Minkowski được sử dụng cho độ tương tự khoảng cách của vectơ. Cho hai hoặc nhiều vectơ, tìm sự tương đồng khoảng cách của các vectơ này.

Input : vector1 = 0 2 3 4
        vector2 = 2, 4, 3, 7
        p = 3

Output : distance1 = 3.5033

Input : vector1 = 1, 4, 7, 12, 23
        vector2 = 2, 5, 6, 10, 20
        p = 2

Output : distance2 = 4.0

Chủ yếu, khoảng cách Minkowski được áp dụng trong học máy để tìm hiểu độ tương tự khoảng cách. Here distance1 and distance2 are almost same so it will be in same near region.  

Python3

Ví dụ: & nbsp;

Lưu ý: Ở đây khoảng cách1 và khoảng cách2 gần như vậy nên nó sẽ ở cùng khu vực. & Nbsp; & nbsp;
