    In the context of machine learning research, science and engineering are not distinct concepts. You don't do "science" by thinking very hard about platonic ML concepts and then publishing your thoughts. You do science by engineering systems that test small ideas, iteratively.

        Also, the general lack of scientific rigor in the field is more often than not coming from people with little engineering experience. If anything, knowing how to deal with system complexity makes your more rigorous (in the sense of the scientific method)

        Buggy code is bad science. Poorly tuned benchmarks are bad science. Poorly factored code is bad science (hinders reproducibility, increases chances of a mistake). If your field is all about empirical validation, then your code *is* a large part of your scientific output.

        Similarly, deployment of ML systems is not a completely independent branch with a one-way connection to research. Remember that the purpose of machine learning research is to *generate knowledge about how to build ML systems that work in the real world*.

        In the same way that the physical reality we can measure is the ultimate referential for physics research, the real-world effectiveness of our algorithms and systems is the ultimate referential for machine learning research.

        Machine learning is not mathematics (if it were, we would call it mathematics)

        I agree - In my research group at @DTUtweet, we develop and apply algorithms specifically designed to address concrete challenges in modeling molecular interactions in the human immune system - So science AND engineering indeed 👍

        Indeed, no need to be elitist about science. If you're confirming your hypothesis through observations and reason, your doing science.

        A difficulty is that in the hectic time/resource constrained world of (urgent!) engineering, it's generally a matter of "We haven't time/resource to do science AND engineering, pick one!" and you get prob half of each; incomplete science, poorly engineered code

        I applied to research and engineering positions. Only the latter moved forward. I don't have a strong publication track in the ML area. Consider the Thomas theorem & human resources biases. Research and engineering are different → much potential is wastedhttps://twitter.com/trylks/status/1016764514140909570?s=19 …

        There's wasted potential in many white males too. Indeed there's a problem in discrimination, but a larger problem in creation of opportunities, core problem: the logistics to make the best use of the human potential for everyone. Very challenging, who can do something about it?

        As outlined by @nntaleb, science vs scientism.
