Reviewer 1 Report
The article presents an intriguing and valuable investigation, delivered with clarity and rigor. Some minor adjustments are recommended to enhance comprehension and fluidity in reading.
In general, it is crucial to specify the author/authors/research institution/project or program responsible for the study leading to some conclusions. Simply using numerical references is inadequate, as the identity behind this contribution remains unclear during seamless text comprehension.
For instance, between lines 42-49 concerning previous studies, it is advisable to provide the authors' names alongside the citation number to improve text readability. This concern persists in both the introduction and the results discussion. Authors are advised to reevaluate and incorporate this essential information in both sections.
While the introduction presents the issue coherently, it would be beneficial to clarify the algorithms and models mentioned around line 90 to contextualize them at that point.
Additionally, adding a closing paragraph to this section outlining the article's structure would be advantageous.
Regarding the methodology section, it's important to elucidate the criteria employed for determining the number of samples for testing and prediction.
Parentheses within Equation 1 should be revised for clarity.
Authors are encouraged to include a visual representation, such as a figure or graph, detailing the sample collection process and key methodologies employed.
Concerning the results section, in line 266: to amend the caption of Figure 3 to include a reference to the final image (d).
The untranslated title 3.3 should also be addressed.
In closing, we extend our heartfelt gratitude to the authors for their diligent research and efforts. We encourage them to persevere in their investigative endeavors.
