4/5 In this example, the first problem is "We don't have an explanation for how the planets move", to which the conjectured explanation is Kepler's laws. The second problem is the observation that they're not accurate enough, and so the laws are improved, etc.
3/5 Then, if there is a problematic observation (problematic = it cannot be derived from Kepler's laws, such as a planetary position that does not fit the model), then the symbolic regression runs again given the problem, and it may find better explanations than Kepler's.
2/5 What I mean is, eg, symbolic regression can find Kepler's laws given data about planetary positions etc. And it does so through conjecture and criticism, since it's a genetic algorithm. I think John Koza may actually have done this for Kepler's third law, but I'm not sure.
1/5 We are on the same page about science being a process of conjecture and criticism that starts with problems.
I recently stumbled upon the concept symbolic regressions. Seems related to Popperian epistemology and explanations. Is being a universal explainer the same as being able to construct universal symbolic regressions (as opposed to just mathematical ones)?
It says the video is unavailable (for me at least).
What's your take on machine learning? It strikes me as induction applied to computer engineering and if I had to guess it does not bring us one step closer to general AI, but I'm curious if that's false.

In the "Logic of Scientific Discovery" chapter 1 section 2, Popper conjectures that intuition plays an important role in coming up with new explanations (creativity). He also quotes Einstein as corroborating this in his address at Planck's 60th birthday.

Instead, he describes the process of conjecture and criticism by which theories can be dismissed. Surviving theories are nonetheless unlikely to be true. That likelihood does not improve with more failed tests. (See Logic of Scientific Discovery, Popper, 1934) 2/2
Loved your book "The Emperor of All Maladies" - just one minor suggestion for improvement. Popper does not describe the process by which scientists "verify" theories. And theories do not gain credibility or robustness when attempts to falsify them fail. 1/2

It is my understanding that to apply knowledge, one has to have knowledge that said knowledge exists in one’s mind. But one has to have knowledge of that second knowledge too, etc. An infinite regress?

Of course, not everything is knowable (see incompleteness), but it just occurred to me that the answer to the question "Is everything knowable?" must itself be knowable. If unknowable, it immediately evaluates to "no".
Musk is right. Here in South Bay traffic has become so bad due to lack of decent public transit, I’d rather wait for the results of an important blood test than be stuck in traffic.

2/2 1) We shall not abandon scientific theories without a good reason to do so (such as finding fault with it or finding a better theory). 2) The game goes on forever and the scientist who declares he/she has found the ultimate theory is automatically disqualified.
1/2 “The Logic of Scientific Discovery” could have been more aptly translated as “The Logic of Scientific Research” imo. Not only is it a more accurate translation, but more importantly, Popper literally describes how research is a game with two basic rules:
