Reviewer 2 Report

This article is related to a cutting-edge topic, digital pathology opportunities and perspectives. The article is well organised and cover almost all initial topics which should be learned for the pathologist who is in the very beginning of digital pathology discovery. The article even contains glossary while many specialists, especially computer scientists even do not take into account how far pathology as a biological related field can be from mathematics-related terminology.

The main question addressed by the research is current point and future trends for digital pathology in different directions covered by this field of the pathology. I suppose that the topic is relevant in the field although not being 100% original because digital pathology is a very popular topic and there are dozens articles related to the fundamental problem of digital pathology in different journals. The article does not address the specific gap in the field but covers the key points of the speciality from basal definitions to specific knowledge concerning neural networks. Being a review the article combines contemporary information about digital pathology impact on routine pathology practice and research directions introducing the reader with the specific features of this field. The article is a non-systematic review, so the author could be recommended to include the information about searching the sources for the plot paying attention to the journals specificity where these article have been published. The biggest minus of the review is lack of author critical analysis of the cited articles. >From my point of view the conclusion is comprehensive and covers the all questions raised posed. The references are appropriate and fresh although there are some impactful articles that would be better to add to make the review more comprehensive. The biggest minus of the review is lack of author critical analysis of the cited articles.

“The article does not address the specific gap in the field but covers the key points of the speciality from basal definitions to specific knowledge concerning neural networks.” - As we wrote in the introduction of the article “this article aims to provide clinicians with accessible information on AI methods used in medicine, without relying heavily on technical jargon”. The reason why we rely on basal definitions is the idea of presentation of the topic in a general and accessible way for Readers.
“The biggest minus of the review is lack of author critical analysis of the cited articles.” - We do not agree that it does apply to us. We made changes and added the section called “Discussion and limitations'' where we criticized the described methods, not the source arts - they were just the source of information to write a simple guide to artificial intelligence and machine learning.
Moreover, we have expanded the discussion paragraph by enriching it with impactful articles. We hope that our paper provides now a more comprehensive review and better illustrates the essence of the subject.

Reviewer 3 Report

1. The current review paper lacks a thorough comparison with other similar reviews, raising concerns about its originality and relevance. Given the presence of multiple reviews on the topic, it is crucial to clarify the unique aspects that make this particular paper interesting.

2. The Discussion Section is inadequate as it fails to provide critical commentary or substantial summaries of the cited papers and their key findings. Consequently, the manuscript's overall organization and quality suffer. Instead of presenting an engaging review, the authors simply compile numerous articles without adding significant value.

3. An ideal review article should encompass a comprehensive and unbiased critique of existing methods, highlighting their strengths and weaknesses. Unfortunately, this aspect is currently absent from the manuscript. Additionally, readers would greatly benefit from a clear explanation of how these methods operate.

4. It would greatly enhance the manuscript if the authors dedicated a section to analysis and offered directions for future research. By providing insights into potential advancements in the field, this addition would contribute to a more robust and insightful review.

5. The authors overlooked recent papers that utilize deep neural networks for the task at hand. It is worth noting that new and highly accurate methods primarily rely on deep neural networks. The exclusion of such papers diminishes the comprehensiveness of the review.

6. The conclusions drawn in the paper should be supported by the evidence presented in the review. It is important to clearly link the findings from the reviewed articles to the overall conclusions and implications. Additionally, the authors should highlight any limitations or areas for future research that arise from the review process.

In general, the paper lacks distinctive qualities that would make it suitable for publication. As a result, I find that this work does not make a meaningful contribution to the existing body of knowledge. Moreover, in addition to the aforementioned issues, the text exhibits significant weaknesses and does not align well with the characteristics typically found in review articles.
