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: Looking into the manuscript, it is clear that the topic is timely and has potential implications to participants in the stock market. However, there are some significant issues that need to be addressed before the paper is considered for publication.

1. Introduction. The structure of the paper should be improved. In particular, the introduction section should be more structured, faster, and cover the key five elements: motivation, objectives, literature gap and paper's contributions to the literature, justification of the methodology, and summary of the results. Furthermore, in the introduction section, the authors clearly describe the added value of their analysis and the positioning in light of previous findings.

2. Related Work. I suggest the authors to analyze more papers that are recently published. Moreover, make sure that literature review is linked to a systematic.

3. The method used should be compared with various methods and the results should be strengthened. The methodological explanation of the method used should be made with the help of assumptions and formulas.

5. The results should be discussed more thoroughly in light of the existing literature. This is a very important point to address.

6. In the conclusion section, a more detailed discussion of the policy implications would make the paper richer and more informative for investors and policymakers.

Reviewer #2: Provide more examples or case studies to demonstrate the practical implementation of the proposed model in clinical settings. This would help in illustrating its applicability and effectiveness in real-world scenarios.

Expand the discussion on the limitations and challenges of your approach, especially focusing on situations where the model may face difficulties due to the unique characteristics of individual treatment plans or variations in equipment across different healthcare facilities.

Include a more detailed comparative analysis with other anomaly detection models that have been applied in similar healthcare settings. Highlighting the specific improvements your model offers over these existing methods would provide a clearer context for your contributions.

Discuss the model's adaptability to other types of quality assurance tasks outside of radiotherapy, potentially broadening the scope of your findings.

Enhance the explanation of how the adaptive resonance features work in layman's terms, to make the paper more accessible to readers who are not specialists in machine learning or medical physics.

Consider the ethical implications of automating such critical aspects of healthcare, particularly the reliance on algorithmic decisions in clinical environments. Discuss safeguards that could be implemented to prevent potential negative outcomes.

Propose future directions for this research, especially in terms of integrating this technology with other AI-driven tools used in healthcare, which could lead to a more comprehensive system for automated quality assurance across various treatment modalities.

Revision 1

Reviewer 1

1. R1C1: Introduction. The structure of the paper should be improved. In particular, the

introduction section should be more structured, faster, and cover the key five elements: moti-

vation, objectives, literature gap and paper’s contributions to the literature, justification of the

methodology, and summary of the results. Furthermore, in the introduction section, the au-

thors clearly describe the added value of their analysis and the positioning in light of previous

findings.

We significantly re-wrote the Introduction section as you suggested and moved most of the

previous introduction to a new Related Work section. The Related Work section includes an

expanded literature review as requested in comments R1C1, R1C2, R1C4, and R2C3.

2. R1C2: Related Work. I suggest the authors to analyze more papers that are recently published.

Moreover, make sure that literature review is linked to a systematic.

We have updated the literature review with the following additional citations, which include

several papers from 2023 and 2024: Commission (2021); Gorokhov et al. (2017); Kehayias

et al. (2023); Li et al. (2023); Lundberg and Lee (2017); Ribeiro et al. (2016, 2018); Saab et al.

(2024); Salam et al. (2024); Union (2024)

3. R1C3: The method used should be compared with various methods and the results should be

strengthened. The methodological explanation of the method used should be made with the

help of assumptions and formulas.

We added a simple explanation of the main idea behind Adaptive Resonance Theory at the

beginning of the Methods section. Additionally, we extensively compare the various methods

and their results in the Discussion section.

4. R1C4: The results should be discussed more thoroughly in light of the existing literature. This

is a very important point to address.

We included four additional papers: Altman et al. (2015); Jensen et al. (2018); Kalendralis

et al. (2023); Kehayias et al. (2023). Our study stands out by using a comprehensive dataset

with over 100 variables and real erroneous plans, unlike previous works that focused on specific

error types, lower-dimensional data, or simulated errors. Our one-class approach overcomes

the limitations of requiring erroneous plans for training, providing a more robust and adapt-

able framework for detecting a wide range of unacceptable plans in radiation therapy. This

discussion is highlighted in blue on page 17 of the revised document.

5. R1C5: In the conclusion section, a more detailed discussion of the policy implications would

make the paper richer and more informative for investors and policymakers.

1

We added explanation on page 20, in accordance with the most prominent AI regulation

document, AI Act published by European Union Union (2024).

Reviewer 2

1. R2C1: Provide more examples or case studies to demonstrate the practical implementation of

the proposed model in clinical settings. This would help in illustrating its applicability and

effectiveness in real-world scenarios.

We added discussions about implementation and limitations in the Discussion section on page

20. Additional studies have been included in the discussion section (See R1C3 and R1C4 on

page 17), comparing their approaches, their results, and some of the implications of the clinical

implementation Kalendralis et al. (2023).

2. R2C2: Expand the discussion on the limitations and challenges of your approach, especially

focusing on situations where the model may face difficulties due to the unique characteristics

of individual treatment plans or variations in equipment across different healthcare facilities.

We added additional discussion of implementation challenges and limitations in the Discussion

section.

3. R2C3: Include a more detailed comparative analysis with other anomaly detection models that

have been applied in similar healthcare settings. Highlighting the specific improvements your

model offers over these existing methods would provide a clearer context for your contributions.

The Related Work section now includes a comparison with alternative methods, highlighting

that deep learning approaches often require additional algorithms for interpretation, lacking

inherent interpretability.

4. R2C4: Discuss the model’s adaptability to other types of quality assurance tasks outside of

radiotherapy, potentially broadening the scope of your findings.

We added a paragraph about other possible applications in the Discussion section.

5. R2C5: Enhance the explanation of how the adaptive resonance features work in layman’s terms,

to make the paper more accessible to readers who are not specialists in machine learning or

medical physics.

See R1C3.

6. R2C6: Consider the ethical implications of automating such critical aspects of healthcare,

particularly the reliance on algorithmic decisions in clinical environments. Discuss safeguards

that could be implemented to prevent potential negative outcomes.

See R1C5.

7. R2C7: Propose future directions for this research, especially in terms of integrating this tech-

nology with other AI-driven tools used in healthcare, which could lead to a more comprehensive

system for automated quality assurance across various treatment modalities.

We added a paragraph about future directions in the Conclusion section.

8. R2C8: Cite this https://doi.org/10.1109/ACCESS.2024.3373697 to improve your litera-

ture.

This paper (Salam et al., 2024) was cited as part of R2C4.

Open letter on the publication of peer review reports

PLOS recognizes the benefits of transparency in the peer review process. Therefore, we enable the publication of all of the content of peer review and author responses alongside final, published articles. Reviewers remain anonymous, unless they choose to reveal their names.

We encourage other journals to join us in this initiative. We hope that our action inspires the community, including researchers, research funders, and research institutions, to recognize the benefits of published peer review reports for all parts of the research system.
