Data Preprocessing in Data Mining

onsider the data as 2-D data points. Given a new data point x = (14, 16) as a query, rank the database points based on the cosine similarity measure A2 1.7 1.9 1.8 1.5 A1 1.5 X1 X2 X3 X4 X5 1.6 1.2 1.5 In other words, find the cosine similarity for each data point and sort in decreasing order: Similarity Vector Closest Second Closest Third Closest Fourth Closest Farthest
