作者论文在修改后，写作方面有了较大的进步，论文的创新度较高，从不同角度

After the revision of the author’s paper, the writing has made great progress. The paper has a high degree of innovation. The vibration signal of the OLTC is extracted from different angles, and a high-dimensional feature matrix is ​​constructed, then fused, and the features are analyzed through IWOA-KNN Choose to get a higher recognition accuracy. But there are still some minor issues before publication, as follows:

After the revision of the author's thesis, the author's writing has made great progress, the innovation degree of the paper is high, from different angles of OLTC vibration signal extraction, the construction of high-dimensional feature matrix, and then fusion, and through IWOA-KNN to select features, to obtain a higher recognition accuracy. However, there are still some minor issues before publication, as follows:
