Interviewers watch whether you can write the MSE gradient without looking it up, explain what the learning rate actually does, and say out loud when you'd just solve the normal equation instead.Open full answer →
49Core difference between machine learning and deep learning, and when would you pick classical ML over a neural net?▼easyDatabricksGoogleScale1 replies◆ premiumThe honest version: deep learning learns its own features but is hungry for data and compute, and on a customer's 50,000-row tabular dataset a gradient-boosted tree wins on accuracy, cost, and time-to-ship. The dividing line and the conditions that flip it.Open full answer →
