This PR improves the model card by:
- Adding the `license: apache-2.0` to the YAML metadata, consistent with the license explicitly stated in the model details.
- Adding the `pipeline_tag: time-series-forecasting`, which accurately reflects the model's purpose in CSI prediction and classification tasks and will improve discoverability on the Hugging Face Hub.
The existing content, including the paper link, code repository, and sample usage, is comprehensive and adheres to the guidelines.
Please review and merge if these changes are appropriate.
