Cosine Similarity

Image
The Java code measure the similarity between two vectors using cosine similarity formula. The vector's element can be integer or double of Java datatype. The cosine similarity of two vectors found by a ratio of  dot product of those vectors and their magnitude. Cosine Similarity Dot product of 2-D Vector Dot product of N-D Vector Vector Magnitude Cosine Similarity of 2-D vectors A class Cosine defined two member functions named " similarity " with parameter type difference, in order to support  parameters  type int and double 2-D vectors.  . Both class (static) member function similarity can be invoked with two array parameters, which represents the  vectors  to measure similarity between them. These vectors must have 2 elements. for example the vectors A =[2 3], B=[3 1] Dot product of two vectors A.B A.B = 2x3 + 3x1 = 6 + 3 A.B = 9 Magnitude o...
