Describe a practical scenario where you would use Hyperopt to tune hyperparameters for a time-series forecasting model. Discuss the specific challenges associated with this type of model and how you would address them using Hyperopt, including the selection of appropriate search spaces and the management of temporal dependencies.
Explanation:
For tuning hyperparameters in a time-series forecasting model, Hyperopt can be used effectively by addressing specific challenges such as handling temporal dependencies and ensuring that the search space includes parameters relevant to time-series analysis. Techniques like rolling window validation can be employed to manage temporal dependencies, and a tailored search space can be defined to optimize the model's performance for time-series data.
