PONE-D-22-01047Improved WOA and Its Application in Feature SelectionPLOS ONE

Dear Dr. GUO,

Thank you for submitting your manuscript to PLOS ONE. After careful consideration, we feel that it has merit but does not fully meet PLOS ONE’s publication criteria as it currently stands. Therefore, we invite you to submit a revised version of the manuscript that addresses the points raised during the review process.

Please submit your revised manuscript by Mar 20 2022 11:59PM. If you will need more time than this to complete your revisions, please reply to this message or contact the journal office at plosone@plos.org. When you're ready to submit your revision, log on to https://www.editorialmanager.com/pone/ and select the 'Submissions Needing Revision' folder to locate your manuscript file.

Please include the following items when submitting your revised manuscript:

• A rebuttal letter that responds to each point raised by the academic editor and reviewer(s). You should upload this letter as a separate file labeled 'Response to Reviewers'.
• 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.

Kind regards,

Reviewer's Responses to Questions

Comments to the Author

1. Is the manuscript technically sound, and do the data support the conclusions?

The manuscript must describe a technically sound piece of scientific research with data that supports the conclusions. Experiments must have been conducted rigorously, with appropriate controls, replication, and sample sizes. The conclusions must be drawn appropriately based on the data presented.

Reviewer #1: Yes

Reviewer #2: Yes

**********

2. Has the statistical analysis been performed appropriately and rigorously?

Reviewer #1: Yes

Reviewer #2: Yes

**********

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: No

Reviewer #2: Yes

**********

4. Is the manuscript presented in an intelligible fashion and written in standard English?

PLOS ONE does not copyedit accepted manuscripts, so the language in submitted articles must be clear, correct, and unambiguous. Any typographical or grammatical errors should be corrected at revision, so please note any specific errors here.

Reviewer #1: Yes

Reviewer #2: Yes

5. Review Comments to the Author

Please use the space provided to explain your answers to the questions above. You may also include additional comments for the author, including concerns about dual publication, research ethics, or publication ethics. (Please upload your review as an attachment if it exceeds 20,000 characters)

Reviewer #1: This paper presents a method called Improved WOA and Its Application in Feature Selection.

1. The parameters used in all algorithms are given in Table 3. It should be stated why these parameter levels are used/chosen. The performances are highly dependent on the chosen levels and for obtaining best solutions one should determine the optimal parameter set for each algorithm.

2. Would you mind please share the codes to check the performance and data.

3. The English writing should be further polished for readability.

4. The introduction paragraph should be presented more extensively.

5.The paragraph “Conclusions” should be enlarged highlighting the innovative contribution of the paper. Please clarify research in conclusions in modest way. Conclusions can be expanded to get clear understating of major findings.

6. it will be good to provide pros and cons of new proposed method.

Reviewer #2: The manuscript, in its present form, contains several weaknesses. Adequate revisions to the following points should be undertaken to justify the recommendation for publication.

1: The previous work section is petite. I recommend adding new meta-heuristic algorithms to this section as well (Remora optimization algorithm, African vulture optimization algorithm, gorilla troops optimization algorithm, etc.).

2: Please add the system specifications used for the evaluation as well as the programming language.

3: Use Friedman statistical test to better evaluation of a proposed method.

4: What method have you used to transfer solutions from continuous search space to binary space? Describe in full.

5: Please add a new section then explain the computational complexity of a proposed method.

6: What is the value of K in the KNN algorithm? Please explain the main reason for the K-value used.

7: Please add future work to the conclusion section and discuss it briefly.

8: What is the main reason for choosing the Gauss/mouse Chaos map, please elaborate more

9: Use other criteria to evaluate the results

10: All the sections and subsections must be included in the text, Such as :(IWOA comparative experiment, etc.).
