| titleOfInvention | Method and system for denoising of magnetotelluric signals based on sparse representation of attention mechanism |
| abstract | The invention discloses a method and system for denoising a magnetotelluric signal based on sparse representation of an attention mechanism. The method obtains a magnetotelluric signal to be denoised and a redundant dictionary, and segments the magnetotelluric signal; and then calculates Each magnetotelluric signal segment and the attention weight of each atom in the redundant dictionary; and then extract the minimum subset of each segment signal from the redundant dictionary based on the attention weight, and then use each atom in the minimum subset to represent The sparse coding matrix, and then the noise contour matrix is obtained based on the product of the sparse coding matrix and the redundant dictionary, and finally the noise contour matrix is used to denoise the signal to be processed. The above method can effectively suppress the large-scale noise in the original magnetotelluric signal, retain the low-frequency slow change trend, and the processing speed is fast, thereby improving the quality of the magnetotelluric signal data, and providing a reliable basis for the subsequent interpretation of the real underground structure. |
