关键词：Gaborletguided sparse filtering A novel intelligent method for lithology identification by vibration signals while drilling
摘要：Highlights This study introduces a novel Gaborlet-guided sparse filtering (GSF) method to improve feature extraction from noisy drilling vibration signals, significantly enhancing lithology identification accuracy. Effective multiscale and multidirectional feature extraction: The GSF method utilizes Gabor wavelets to initialize sparse filter (SF) weight vectors, enabling the capture of multiscale and multidirectional features crucial for precise lithology classification. Overfitting prevention via regularization: The GSF model employs L1/2 norm regularization, effectively addressing overfitting while ensuring reliable feature extraction from raw drilling data. Exceptional classification performance: Experimental results show that the proposed method achieves 94.07% accuracy on the training set and 88.32% on the testing set, outperforming three other existing lithology identification techniques.
