So i made a ML model to diagnose a disease for way cheaper, way more accessible, and more accurate than it is currently. Therefore, I can make big claims on how impactful it could be. I can prove these claims with the performance on the validation set and by just estimating the cost. However, I don't actually have a way of like applying this in the real world, so can i still make big claims like this when i don't have real world proof of how this would work? Also, i'm 90% sure my model isn't overfit i did everything i could to minimize that including strong reg, validation set, smote, etc, and stuff so the accuracy is legit

do colleges and research programs care where you publish? i found a journal run by some institution in india thats pretty sketchy according to online stuff but they are google scholar pubmed indexed and only cost 45 to publish or can i settle for a high school journal but not the super expensive predatory ones https://ijsrst.com/index.php/home and this is similar story: https://www.cureus.com also i dont wanna spend ages figuring out publishing after writing a long as paper

So i found actual grad-level journals that are good and could publish my research for free https://link.springer.com/journal/10916/articles https://alz-journals.onlinelibrary.wiley.com/toc/23528729/current https://link.springer.com/journal/44174 they dont explicitly say if they publish high schoolers or not (i wrote and did it on my own)(computational project) but have a uni prof mentor helping me since they dont explicitly say whether or not they take high schoolers, and it doesnt look like any have published in it, should i first email them asking if they will? thing is they might assume that a high schoolers research would be trash and automatically say no without looking at my paper, but if i just submit it they would see the research and be convinced that its worthy of submission? anyone have guidance on what i could do

Im writing a paper and what software should i use to make tables or do it directly with google docs inbuilt table function

in science fairs, are you allowed to have graphics/visual representations from other sources not made yourself as long as you cite it? for instance if im trying to explain how a certain algorithm or theory or concept and want to use a visual, could i just find one from online and put it but still cite where i got it from even if you are allowed too, does it make your project look worse to judges? same question for publications
