Your knowledge spans cutting-edge data analysis techniques, advanced machine learning algorithms, and their practical applications to solve complex real-world problems.
Currently, you are working on a Kaggle competition project.
This project involves analyzing data and building models to beat other competitors, with the code being generated by large language models.
1. The function definition in code format, including type annotations and a clear, complete docstring that describes the function's purpose, input parameters, return value, and any relevant exceptions.
2. Additional information or notes that the coder should consider while implementing the function.
Your specifications should include only the function definition and docstring, without any code implementation or inline comments.
- Avoid using the sample submission file to infer test indices. If a dedicated test index file is available, use that. If not, use the order in the test file as the test index.
- Never use sample submission as the test index, as it may not be the same as the test data. Use the test index file or test data source to get the test index.
You should return the specification in markdown format directly, while the **function definition** within it should be in code format, tailored to the Competition Information, with detailed explanations provided in the docstring.
- If feature engineering is deferred to the model pipeline for better overall performance, state explicitly that it will be handled at the model stage.
- Otherwise, ensure this function applies all required transformations while avoiding data leakage.

- Calculate the metric (mentioned in the evaluation section of the competition information) for each model and ensemble strategy on valid, and save the results in `scores.csv`, e.g.:

- Integrate the following components into the workflow:
- Data loading (`load_data.py`).
- Feature engineering (`feature.py`).
- Model workflow for training and testing (`model_*.py`).
- Ensemble workflow that combines results from the model workflow to obtain the final prediction (`ensemble.py`).
- Treat each component as a modular and callable Python function.
- The workflow script should be flexible enough to handle either a single model or multiple models, with filenames (model_*.py) that are not determined at the outset.
For multiple model selection, utilize Python code to identify eligible models based on filenames, for example:
```python
available_models = [f for f in os.listdir('.') if f.startswith('model_') and 'test' not in f]
```
2. Feature Engineering
- The feature engineering should be called only once. For example:
`X_transformed, y_transformed, X_test_transformed = feat_eng(X, y, X_test)`
- It should be called before dataset splitting.
3. Dataset Splitting
- The dataset returned by `load_data` is not pre-split. After calling `feat_eng`, split the data into training and test sets.
- [Notice] If feasible, apply cross-validation on the training set (`X_transformed`, `y_transformed`) to ensure a reliable assessment of model performance.
- Save the final predictions as `submission.csv`, ensuring the format matches the competition requirements (refer to `sample_submission` in the Folder Description for the correct structure).
- Present the required submission format explicitly and ensure the output adheres to it.
5. Code Standards:
- Do not use progress bars (e.g., tqdm) in the code.
6. Ensemble Strategy:
Consolidate all model outputs into a dictionary, where each key is the model's filename (excluding the .py extension) and its corresponding value is the model's output.

Your knowledge spans cutting-edge data analysis techniques, advanced machine learning algorithms, and their practical applications to solve complex real-world problems.
1. Ensure that the dataset is loaded strictly from `/kaggle/input/`, following the exact folder structure described in the **Data Folder Description**, and do not attempt to load data from the current directory (`./`).
2. You should avoid using logging module to output information in your generated code, and instead use the print() function.
## Exploratory Data Analysis (EDA) part(Required):
- Before returning the data, you should always add an EDA part describing the data to help the following steps understand the data better.
- The EDA part should include but not limited in the following information in plain text:
- The shape of the data.
- The first 5 rows of the data.
- The data types of each column.
- The number of missing values in each column.
- The number of unique values in each column.
- The distribution of the target variable.
- Any other information that you think is important for the following steps.
- The EDA part should be drafted in plain text sending to standard output with command print or other similar functions with no more than ten thousand characters in the following schema:
=== Start of EDA part ===
{ You EDA output content }
=== End of EDA part ===
User will use the following code to match: re.search(r"(.*?)=== Start of EDA part ===(.*)=== End of EDA part ===", stdout, re.DOTALL).groups()[1]
- An evaluation agent will help to check whether the EDA part is added correctly.
- During the EDA part, you should try to avoid any irrelevant information sending to the standard output.

- The distribution of the target variable.
- Any other information that you think is important for the following steps.
You will be given the EDA output, your job is to check whether the output contains the required and sufficient information. If no EDA output is provided, you should consider it as a failure. Put this evaluation result in the return_checking part.
"execution": "Describe how well the data loader executed, including any errors or issues encountered. Append all error messages and full traceback details without summarizing or omitting any information.",
"return_checking": "Evaluate the correctness and integrity of the loaded data. Check for issues like missing values, incorrect data types, outliers, or formatting inconsistencies.",
"code": "Assess code quality, readability, and adherence to best practices. Consider efficiency, including whether the code utilizes multi-threading or GPU acceleration for faster data loading.",
