Thus, another solution is to train the NN to detect scenes that contain potential adversarial inputs.
No, it's not a solution: such attacks cannot be detected because both original and perturbed image are perfectly valid inputs.

The problem lies with the architecture itself. A feed-forward convolutional network is not enough. I am hopeful about this approach, waiting for the authors to test the robustness of their network against adversarial attacks.

That figure 1 has done it for met. The models and theory are wrong, totally.
And soon all this stuff will be used in hospitals etc.

In  CAD/CAM a rotated compressor is still a compressor. Now AI transforms a revolver to a mousetrap just by flicking it. Perceptron XOR all over again.
Probably means it won't work for moving part simulation"??? Just guessing of courses

For the avoidance of doubt: they won't deploy this algorithms in hospitals unless they pass the same clinical trials as other methods of treatment or diagnosis.

"The research has been submitted to a peer-reviewed medical journal amid hopes that the technology could enter clinical trials within a few years."

They're not going to dump this on the patients tomorrow.

Like Thalidomide? There's no one on those commissions who understands those models. All competent experts have their money in the  AI business.

There are some ML people who make a career out of bashing the Deep Learning fad, most notably Gary Marcus and Filip Piekniewski. And I'm sure they'll find a suitably jaded statistician to take the models under scrutiny.

Only if ML gents will be wiling to roll their sleeves up and do the testing themselves, because no one else has so much computational power to waste - I'm definitely against it as a climate change believer.

Once you train it, you don't need that much power. I think the model used for Moorfields diagnostics can easily run on a single PC.

OK, but we are not discussing the rare good ML work, but the whole sewage of poor papers which ruin my science experience.

Here, we have considered three, four, and five degree polynomial for regression fitting. One may consider higher degree polynomial in the simulation but it has been seen that by increasing the degree of the polynomials, the accuracy does not usually increase. In the future, it needs to develop a methodology about what degree polynomial one should use to get a result with acceptable  accuracy. This is however not of the scope of this paper and the authors are working in this direction and hope to communicate the findings in the future.

What does this mean?

I went to an AI doctor, told him that I broke my wrist in 2 places. Guess what he told me? Don't go to those places.Still more accurate than my human GP.

That would be awesome if AI was capable of such common sense advice.
