# The evaluation metric for this competition is "R² (coefficient of determination)".
R² is a standard metric for regression that measures the overall performance of a model by assessing how well its predictions align with actual values.
* Higher R² values indicate that the model is making accurate predictions and capturing meaningful patterns in the data.
* Lower R² values suggest that the model struggles to generalize and may be missing key relationships.

# Submission Format
Your submission file must be in CSV format and should contain two columns:
`id` – The unique identifier for each test sample.
`ChlorA` – The predicted chlorophyll concentration for each test sample.

Please ensure that your submission adheres to the following requirements:

1. The `id` column in your submission should correspond to the same ID numbers as provided in the `test.csv` file. Note that the IDs may not be in sequential order.
2. Take a look at the example `sample_submission.csv` provided to understand the format and structure of the submission file.

Your submission file should contain a header and have the following format:


```markdown
id,ChlorA
376970,0.9026
59898,0.9226
247101,1.4513
 ...
```
Please make sure that your submission file follows the specified format and includes the correct predictions for the corresponding IDs in the `test.csv` file.
