what is ML actually? as an econ masters student with no background in CS i assumed it was a black box i'd need a whole other degree to open. turns out i'd sort of been learning the core of it since my first econometrics class. what i describe here is only one type of neural network, a feed-forward network. there are far more complicated architectures, but they all run on the same logic: choose parameters to minimize a loss function. watch till the end for how a neural network actually learns its weights, using nothing but the chain rule. economists: have you used artificial neural networks in place of any regressions in your analyses? i made this account to break down topics in economics in simple terms. follow for more. #economics #econometrics #machinelearning #neuralnetworks #datascience

On the foundational (unrealistic) assumptions in microeconomics and why we make them. Are these always realistic? No. But economic models aren’t necessarily trying to perfectly recreate human behaviour. These assumptions make behaviour mathematically tractable enough to analyze, derive predictions from, and test against real data. Watch till the end for the one question that tells you whether a model's result is robust or fragile. Do unrealistic assumptions make a model useless, or do they make it usable?
