The theoretical part is reproduced from this article blog:http://blog.csdn.net/luoweifu/article/details/8214959 the blog gives Java code, I use C + + to implement it.Theory:In addition to the Fourier transform, the orthogonal transformations

Suppose the data is as follows, where the row represents the user, and the column represents the rating item: Let's look at the three formulas first. Cosine similarity (cosine-based similarity): Pearson coefficient (Pearson correlation): Fixed

In addition to Fourier transformation, commonly used orthogonal transformations in image processing also have some useful orthogonal transformations. The Discrete Cosine is one of them. Discrete cosine transform is represented as DCT (discrete

C language cos () function: Cosine valueheader file: #include The Cos () function is used to find the cosine value, that is, the ratio of the side length of the angle to the length of the hypotenuse, and the prototype is:
