  • Big if true. Current academic evaluation system via poor KPIs is more similar to a “call center” evaluation system than something useful. It is the main reason most of the best young scholars I know have left academia for industry. Everyone I knew in academia good enough to find something else elsewhere left, those who couldn’t remained, and are burn out, stuck in the rat race.

    It is sad, because we were all ready to accept less money and being overworked for the idea to do something useful. And society lost so much value due to a broken corrupted system that squashes human dignity to make money for small mafias, institutions and publishers


  • Because he was ceo of a company in a critical position to define the future of economy. Currently the tech field is the biggest and most influential of all economic fields. And by tech here we talk about digital world. There’s absolutely no comparable sector at the moment for importance, not even pharma.

    It literally defines the modern economy. In the field, openai is an incredibly important company for future relative success and power of big tech companies.

    This is why it is so important for world economy







  • In the easiest example of a neuron in a artificial neural network, you take an image, you multiply every pixel by some weight, and you apply a very simple non linear transformation at the end. Any transformation is fine, but usually they are pretty trivial. Then you mix and match these neurons to create a neural network. The more complex the task, the more additional operations are added.

    In our brain, a neuron binds some neurotransmitters that trigger a electrical signal, this electrical signal is modulated and finally triggers the release of a certain quantity of certain neurotransmitters on the other extreme of the neuron. Detailed, quantitative mechanisms are still not known. These neurons are put together in an extremely complex neural network, details of which are still unknown.

    Artificial neural network started as an extremely coarse simulation of real neural networks. Just toy models to explain the concept. Since then, they diverged, evolving in a direction completely unrelated to real neural network, becoming their own thing.


  • No, what you describe is a basic decision tree. Let’s say the simplest possible ML algorithm, but it is not used as is in practice anywhere. Usually you find “forests” of more complex trees, and they cannot be used for generation, but are very powerful for labeling or regression (eli5 predict some number).

    Generative models are based on multiple transformations of images or sentences in extremely complex, nested chains of vector functions, that can extract relevant information (such as concepts, conceptual similarities, and so on).

    In practice (eli5), input is transformed in a vector and passed to a complex chain of vector multiplications and simple mathematical transformations until you get an output that in the vast majority of cases is original, i.e. not present in the training data. Non original outputs are possible in case of few “issues” in the training dataset or training process (unless explicitly asked).

    In our brain there are no if/else, but electrical signals modulated and transformed, which is conceptually more similar to the generative models than to a decision tree.

    In practice however our brain works very differently than generative models









  • I like this :D

    And, in news that seems entirely unbelievable in Maryland, where a bushel of steamed crabs is an expensive treat and crab cakes are on just about every restaurant menu, Italians have little desire to eat their way out of this crab conundrum.

    We will eventually eat them, we just need to understand how to properly make a pasta sauce out of it! Already some people are eating them, we need time to refine the recipes to become more popular :D


  • I am pretty sure it is also about “cultural” taste. Italians have more types of pasta, cheese and wines of any country in the world and they can tell the difference of each of them at a extreme level. Italians are pretty pedantic on food

    I am not an expert in crabs, no idea of the names of common mediterranean crabs, sorry. But searching on Wikipedia one apparently is called in English Maja squinado, another Mediterranean green crab…

    As said, I might be wrong with these names
