What is underfitting and overfitting? How to avoid it? 2. What is the difference between batch, SGD and mini-batch gradient descents? When will you use each? 3. How to choose a machine learning model? 4. How to improve the latency of a machine learning model in production? 5. If your training and cross validation accuracies are high, but testing accuracy is less - how would you debug this? 6. Name 3 hyper-parameters. Why can’t we train them as hyper-parameters, why should only humans set them? 7. Which metric should be used to evaluate a classifier? How do you connect it to business value? 8. What prevents someone to select deep learning model for everything? 9. Say you have to classify a lot of data, but you don’t have labelled training examples. How would you begin to solve the problem? How many training data points are needed? 10. Say you have a perfectly working machine learning model. How do you deploy this in production? How do you check if users will actually like it?
