Your question is Transformers and Time Series. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Have you heard of transformers, time series, supervised learning, and unsupervised learning? Explain how you would approach each.
Discuss the data requirements, modeling workflow, validation strategy, statistical assumptions, and evaluation methods for each approach. Highlight how you would select among classical time-series models, transformer-based models, supervised methods, and unsupervised techniques when the objective and data structure are uncertain.
