Connectionists: Rising Stars in AI Symposium at KAUST: Protocol Flaws

Danko,

I must provide a deeper insight into your comment: "Write down: The
original study reported the performance of A. The true performance is B.
And B < A."

If the truth is that B can report only 10% correct, A can report 99.99%
correct or any higher percentage, if one uses a flowed
protocol---Post-Selections Using Validation Sets (PSUVS) or Post-Selections
Using Test Sets (PSUTS) depending on whether A reports validation
performance or test performance.

I  have proven the following theorem, in a manuscript currently being
evaluated by a journal (an archival version of my IJCNN 2021 paper about
Post-Selections):

Theorem 4 (Post-Selection Illusion): Given any nonzero validation error
rate and nonzero test error rate, the nearest neighbor classifiers with a
confidence threshold in Definition 4 satisfies the validation error rate
and the test error rate, if the computational resources and the time spent
on Post-Selections are not bounded.

With an explosion of the number of false papers, the AI field is in a great
crisis of protocol flaw.

Best regards,
-John
