• A marked-up copy of your manuscript that highlights changes made to the original version. You should upload this as a separate file labeled 'Revised Manuscript with Track Changes'.
• An unmarked version of your revised paper without tracked changes. You should upload this as a separate file labeled 'Manuscript'.

If you would like to make changes to your financial disclosure, please include your updated statement in your cover letter. Guidelines for resubmitting your figure files are available below the reviewer comments at the end of this letter.

If applicable, we recommend that you deposit your laboratory protocols in protocols.io to enhance the reproducibility of your results. Protocols.io assigns your protocol its own identifier (DOI) so that it can be cited independently in the future. For instructions see: https://journals.plos.org/plosone/s/submission-guidelines#loc-laboratory-protocols. Additionally, PLOS ONE offers an option for publishing peer-reviewed Lab Protocol articles, which describe protocols hosted on protocols.io. Read more information on sharing protocols at https://plos.org/protocols?utm_medium=editorial-email&utm_source=authorletters&utm_campaign=protocols.

We look forward to receiving your revised manuscript.

3. Have the authors made all data underlying the findings in their manuscript fully available?

The PLOS Data policy requires authors to make all data underlying the findings described in their manuscript fully available without restriction, with rare exception (please refer to the Data Availability Statement in the manuscript PDF file). The data should be provided as part of the manuscript or its supporting information, or deposited to a public repository. For example, in addition to summary statistics, the data points behind means, medians and variance measures should be available. If there are restrictions on publicly sharing data—e.g. participant privacy or use of data from a third party—those must be specified.

Reviewer #1: Yes

Reviewer #1: This work proposes a multi-domain collaborative denoising bearing fault diagnosis model based on dynamic inter-domain attention mechanism and noise-aware loss. The paper is well-structured and presents promising results. To further enhance the manuscript, the following suggestions are offered:

1.The Abstract could benefit from a clearer emphasis on the practical significance of this research. Highlighting the engineering context and potential real-world applications would help readers better understand the value of the proposed method.

2.While the authors have provided a thorough review of current research, it would be beneficial to more explicitly summarize the existing research gaps before introducing the contributions and novelty of this work. Additionally, expanding the discussion to include emerging trends in machine learning and signal processing—particularly in industrial applications—could strengthen the manuscript. For example, exploring connections to recent advancements in areas such as digital twin methodology for vibration-based monitoring and prediction of gear wear, novel cyclic-correntropy based indicator for gear wear monitoring, and neuro-fuzzy system-guided cross-modal zero-sample diagnostic framework using multi-source heterogeneous non-contact sensing data could provide valuable context and demonstrate the broader relevance of this research.

3.The resolution of the figures in the manuscript could be improved to ensure clarity and enhance the overall presentation of the results.

4.There are occasional grammatical errors throughout the manuscript. A thorough proofreading to address these issues would improve the readability and professionalism of the paper.

5.Including a section on potential future research directions at the end of the Conclusion would provide a forward-looking perspective and inspire further exploration in this field.

Reviewer #2: 1.The manuscript is generally clear and conveys the research content and methodology effectively. However, there are several grammatical errors, overly complex sentence structures, and awkward phrasing that affect readability. Some technical expressions are rigid, making it difficult for readers to follow the core ideas. I recommend further language polishing to enhance fluency and readability, ensuring that the content is easily understandable.

2.Your study presents certain improvements and new approaches, particularly in signal processing and fault diagnosis within the field of mechatronic engineering. However, the level of innovation is not sufficiently emphasized. The differences between your proposed method and existing approaches need to be highlighted more clearly. I suggest strengthening the comparison in the introduction and discussion sections to explicitly outline the novel contributions of your work.

3.Your manuscript generally aligns with the journal’s scope, which covers topics related to mechatronic engineering. However, the experimental validation lacks strong supporting evidence. The manuscript would benefit from additional comparative experiments or a more detailed performance analysis. To improve the scientific rigor of the study, I strongly recommend providing more experimental data, especially direct comparisons with existing methods.
