| Abstract(in English) | There are many techniques for mode estimation, such as graph spectrum and mean shift. Generally, these conventional techniques have some fundamental problems caused of determination of kernel window width and convergence to local optima. Although some methods have tried to overcome these problems, it was resulted in increasing calculation cost. Introducing assumption that main cluster follows Gaussian distribution loosely, a mean shift technique in which kernel window width can be estimated iteratively and is utilized for mode estimation. This article investigated consistency and unbiasedness of the technique numerically, and applied to background sound spectrogram estimation. |
