What is the meaning of the mean_shift? - PyTorch Forums

WebThe underlying idea of the Mean Shift algorithm is that there exists some probability density function from which the data is drawn, and tries to place centroids of clusters at the maxima of that density function. It approximates this via kernel density estimation techniques, and the key parameter is then the bandwidth of the kernel used.

WebThe arithmetic mean is the sum of the elements along the axis divided by the number of elements. Note that for floating-point input, the mean is computed using the same precision the input has. Depending on the input data, this can cause the results to be inaccurate, especially for float32 (see example below).
