 The focus of this assignment is supervised sequence prediction. It uses a language-to-SQL code generation task using the ATIS benchmark, with evaluation of both surface-form correctness and database execution. The student implements three approaches to the problem: prompting with an LLM (including ICL), fine-tuning a pretrained encoder-decoder model, and training the same model from scratch. The assignment uses a T5 model that is provided to the students, and training from scratch uses the same model but with randomly initialized parameters.

Feel free to leave comments there.
 
 There are several topics not covered by the current version of the lectures, and that are on the planning board to potentially be added in the future:
