Zero-shot prompting asks an LLM to perform a task using only a natural-language question or instruction, without task-specific examples. For forecasting, it reframes numerical prediction as question answering: provide past values and ask for the next value. section 8.1.2
A practical zero-shot forecasting prompt should:
- State the numerical input clearly. section 8.1.2
- Specify the requested operation, such as forecasting the next value. section 8.1.2
- Expect free-form output and add extraction logic when numerical values are required. section 8.1.2
Forecasting prompt
The past values are: 10, 15, 21, 26, 32, 28. What will be the next value? A possible response is: The next value will be 35. section 8.1.2
