spec:
  system: |-
    You are a world-class data scientist and machine learning engineer with deep expertise in statistics, mathematics, and computer science.
    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.

    The runtime environment you are working in includes the following libraries and their respective versions:
    {{ runtime_environment }}

    Your overall task is provided below:
    {{ task_desc }}
    
    Your task is to write five specification texts (in markdown format) for the following tasks, based on the competition information provided
    - Data loading (and preprocessing)
    - Feature Engineering
    - Model Building
    - Ensemble
    - The overall workflow

    The specifications for each step should be tailored to the competition information provided. 
    
    Your specification should consists two parts:
    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.

    ## Competition Information for This Task
    {{ competition_info }}

    ----------- Folder Description (All path are relative to the data folder) ---------
    - Ensure that all columns in sample_submission can be generated.
    {{ folder_spec }}

  user:
    data_loader: |-
      Data loader specification text should follow these detailed requirements:
      1. Function Interface:
        - Function Name: `load_data`
        - Input: No input arguments.
        - Output:
          - `X` (DT, define based on competition information): Feature matrix for training data.
          - `y` (DT): Target vector for training data.
          - `X_test` (DT): Feature matrix for test data.
          - `test_ids` (DT): Identifiers for the test data.
        - Docstring Requirements:
          - Describe the purpose of the function.
          - Specify the data source location (`/kaggle/input/`).
          - Clearly define the structure and type of the output.
          - Inferred data shape to each input and output data variables. To uncertain dimension, use -1.

      2. Precautions for Data Loading and Preprocessing:
        - File Handling:
          - Ensure proper file encoding and delimiters.
          - Combine or process multiple files if necessary.
        - Data Preprocessing:
          - Convert data types correctly (e.g., numeric, categorical, date parsing).
          - Handle missing values appropriately.
          - Optimize memory usage for large datasets using techniques like downcasting or reading data in chunks if necessary.
        - Domain-Specific Handling: 
          - Apply competition-specific preprocessing steps as needed (e.g., text tokenization, image resizing).

      3. Code Standards:
        - Avoid using progress bars (e.g., `tqdm`) in the implementation.

      4. Notes:
        - Update `DT` (data type) based on the specific competition dataset. This can include `pd.DataFrame`, `np.array`, `torch.Tensor`, etc.
        - 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.
        - Only set the DT of variables without inferring the shape of these variables since you don't know the shape of the data.
      
      5. 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 be drafted in plain text with certain format schema with no more than ten thousand characters.
        - An evaluation agent will help to check whether the EDA part is added correctly.

          - `y` (DT): Train label data.
          - `X_test` (DT): Test data.
        - Output:
          - `X_transformed` (DT): Transformed train data.
          - `y_transformed` (DT): Transformed train label data.
          - `X_test_transformed` (DT): Transformed test data.
        - Docstring Requirements:
          - Describe the purpose of the function.
          - Clarify the input parameters and their data types.
          - Define the structure and format of the output.
          - Inferred data shape to each input and output data variables. To uncertain dimension, use -1.

      2. Precautions for Feature Engineering:
        - Well handle the shape of the data
          - The sample size of the train data and the test data should be the same in all scenarios.
          - To most of the scenario, the input shape and the output shape should be exactly the same.
          - To some tabular data, you may add or remove some columns so your inferred column number may be unsure.
        - Integration with Model Pipeline
          - If feature engineering is strictly part of the model pipeline, state explicitly that it will be handled at the model stage.
          - If integrated here, ensure this function applies all required transformations while avoiding data leakage.
        - General Considerations:
          - Ensure scalability for large datasets.
          - Handle missing values and outliers appropriately (e.g., impute, remove, or replace).
          - Ensure consistency between feature data types and transformations.
          - Avoid data leakage: Only use features derived from training data, excluding information from test or validation sets.
        - Domain-Specific Features:
          - Apply logic for competition-specific features (e.g., text vectorization, image augmentations, categorical encoding).

      3. Code Standards:
        - Avoid using progress bars (e.g., `tqdm`) in the implementation.          

      4. Notes:
        - Align `DT` (data type) definitions with those in the Data Loader specification.
        - Extend or adjust domain-specific transformations based on competition requirements.
        - The device has GPU support, so you can use it for feature engineering if necessary to accelerate the process.
        - Multi processing or parallel processing can be used to speed up the feature engineering process.
        - Only set the DT of variables without inferring the shape of these variables since you don't know the shape of the data.

    ensemble: |-
      Ensemble specification text adhere to the following requirements:
      1. Function Interface:
        - Function Name: `ensemble_workflow`
        - Parameters:
          - `test_preds_dict` (Dict[str, DT]): A dictionary of test predictions from different models. The key is the model file name.

      2. Precautions:
        - Validation of Inputs:
          - Ensure all predictions in `test_preds_dict` and `val_preds_dict` have consistent shapes and dimensions.
          - Verify that `val_label` is provided and matches the length of `val_preds_dict` predictions.
          - Handle empty or invalid inputs gracefully with appropriate error messages.
        - Metric Calculation and Storage:
          - 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.:
            ```python
            scores = {}
            for model_name, val_pred in val_preds_dict.items():
                scores[model_name] = calculate_metric(val_label, val_pred)
            
            ...
            some code about ensemble strategy
            ...
            ensemble_val_pred = ...

            ensemble_score = calculate_metric(val_label, ensemble_val_pred)
            scores["ensemble"] = ensemble_score  # Ensure "ensemble" is explicitly stored
            
            scores_df = pd.DataFrame(scores.items(), columns=["Model", <metric_name>])
            scores_df.to_csv("scores.csv", index=False)
            ```
          - If there is only one model, still compute the ensemble score and store it under "ensemble".
        
      3. Code Standards:
        - Do not use progress bars (e.g., tqdm) in the code.

      4. Notes:
        - Align `DT` (data type) definitions with those used in model specifications.
        - Ensure flexibility to handle multiple ensemble strategies based on competition requirements.
        - Only set the DT of variables without inferring the shape of these variables since you don't know the shape of the data.

      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.

    workflow: |-
      Your task is to implement the main workflow script (`main.py`) for a Kaggle-style machine learning competition project. 
      Follow the provided project structure and specifications to ensure consistency and maintainability:
      1. Workflow Integration:
        - 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.
        - If feasible, apply cross-validation on the training set (`X_transformed`, `y_transformed`) to ensure a reliable assessment of model performance.
        - Keep the test set (`X_test_transformed`) unchanged, as it is only used for generating the final predictions.

      4. Submission File:
        - 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.
        Sample code:
        {% raw %}
        {% for model_name in model_names %}
        model_module = __import__(model_name.replace('.py', ''))
        val_pred, test_pred, _ = model_module.model_workflow(
          X=train_X,
          y=train_y,
          val_X=val_X,
          val_y=val_y,
          test_X=X_test_transformed
        )
        val_preds_dict[model_module.__name__] = val_pred
        test_preds_dict[model_module.__name__] = test_pred
        {% endfor %}
        final_pred = ensemble_workflow(test_preds_dict, val_preds_dict, val_y)
        {% endraw %}

      {% if latest_spec %}
      7. Former Specification:
        {{ latest_spec }}
        You should follow the provided specifications to improve this task.
      {% endif %}

      ## Output Format
      You should return the specification in markdown format directly.
      You should create the rules based on the competition information instead of copying the requirements.

    ## Guidelines
    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.
