Super interesting. Loved it. In my own work I tend to prefer a statistical approach for reasons of privacy (personal data) and explainability. The second part I would have loved the discussion to have drilled down on: what’s the value of outcomes without understanding? In my field I must be able to explain how I derive results. If I were to use ML I’d be able to scale but without understanding how I generate results.

Thank you very much for uploading this discussion. I greatly appreciated this as someone with a background in econometrics, who couldnt really grasp how machine learning is not just "spicy statistics". It can be confusing for me, as classical statistical concepts are often redefined in machine learning with different names, but the power of computers is undeniable in dealing with complex large datasets.

About legal aspect, it is also true for statistical models. If you use logistic model to make a decision and is wrong and costly, who should be blamed?

The only real discussion that's (not) being had here is how the true "problem" is that of time-required for problems. Anything else is just jargon and conjecture.

I'm struggling to understand how occums razor applies to neural networks. For example, I thought the process of model selection should favor the simplest combination of variables e.g. AIC. But neural nets seem to assume the opposite, that large combinations of parameters model complexity well so are a good thing.

well for complex problems not having enough parameters will induce a strong bias in a model, so that is something you dont want either.

There's a sweet spot for number of parameters in any model, NNs included. "Overfitting" is basically industry jargon for overly complex modeling. I've seen models overly parameterized or overly complicated frequently beaten by simpler ones. In any case, Occum's razor doesn't *have* to apply to anything... it's just an aphorism, not a law of physics.

@@jamesdavis3851 and @macx7760 thank you both for responding. My perception is that these neural network modelling methods really just create over-parametrized models with high predictive power at the expense of explanatory power. However, I now think that AI engineers are primarily (and maybe even exclusively) directed to find tools with predictive power and don't care about explanation, while classical statistics was developed by scientists trying to ask and answer 'why/how' questions. In other words, neural network algorithms are developed by engineers wanting to 'do' and the explanation doesn't really matter if you are trying to better sell advertising, or build a walking robot, or land a rocket, etc.

@@joefish6546 That's kinda what "engineer" implies - applications/solutions, not research or explanations. But also, getting solutions by any means still potentially gives insights to the underlying system. Sometimes the goal is to understand, and insight can come from anywhere... but I don't disagree that the primary goal of any engineer is to solve.
