    logistic regression/logit function/max likelihood
    regularization ( lasso/ridge, l1/l2)
    dimensionality reduction
    k-means/EM
    precision/recall
    neural network: activation function, stochastic gradient descent

    • A DS in analytics is often just an analyst with an inflated title so I think it would be rare to actually need NN knowledge

    • I feel like this idea needs to die. Data science clearly comes from the idea of applying quantitative ideas from science to data work in companies. I.e. what a data analyst does but plus understanding-focused models, forecasting & experimentation. NN are rarely if ever needed for this type of work, just like no medical researcher uses NNs to study the effectiveness of a treatment for example.

      I think it's great for DS that ML eng now exists, because that means the DS role can finally be defined as data-savvy person who does everything in between DE and MLE.
