Description: # Iljicevs ML
        
        Iljicevs ML is a Python library designed to simplify the process of selecting, training, and optimizing multiple machine learning models in an ensemble approach. It provides functionalities for dynamic model selection, hyperparameter tuning, feature importance, cross-validation with multiple metrics, and more.
        
        ## Features
        
        - **Model Hyperparameter Tuning**: Automatically search for the best hyperparameters using GridSearchCV.
        - **Dynamic Model Selection**: Selects the best performing models based on cross-validation results.
        - **Weighted Average Predictions**: Combines predictions from multiple models by averaging their outputs based on accuracy weights.
        - **Feature Importance Visualization**: Displays the importance of features across ensemble models.
        - **Class Balance Checking**: Automatically checks class balance and suggests solutions for unbalanced datasets.
        - **Cross-validation with Metrics**: Supports evaluation with multiple metrics (Accuracy, F1, ROC AUC, etc.).
        - **AutoML Support**: Automatically selects models based on dataset characteristics.
        
        ## Installation
        
        To install the package, simply use `pip` (once it is published to PyPI):
        
        ```bash
        pip install iljicevs_ml
        ```
        Or, if you want to install directly from the source:
        
        ```bash
        git clone https://github.com/yourusername/iljicevs_ml.git
        cd iljicevs_ml
        python setup.py install
        ```
        
        ## Usage
        
        ### Basic Example
        
        Here's an example of how you can use iljicevs_ml to select models, tune their hyperparameters, and evaluate their performance.
        
        
        ```Python
        from iljicevs_ml import IljicevsModel
        from sklearn.ensemble import RandomForestClassifier, GradientBoostingClassifier
        from sklearn.linear_model import LogisticRegression
        from sklearn.svm import SVC
        from sklearn.datasets import load_iris
        from sklearn.model_selection import train_test_split
        
        # Load data
        data = load_iris()
        X = data.data
        y = data.target
        
        # Train-test split
        X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.3, random_state=42)
        
        # Define models and hyperparameters
        models = {
            'logistic_regression': LogisticRegression(max_iter=200),
            'random_forest': RandomForestClassifier(),
            'svm': SVC(probability=True),
            'gradient_boosting': GradientBoostingClassifier()
        }
        
        param_grids = {
            'logistic_regression': {'C': [0.1, 1, 10]},
            'random_forest': {'n_estimators': [50, 100], 'max_depth': [5, 10]},
            'svm': {'C': [0.1, 1, 10], 'kernel': ['linear', 'rbf']},
            'gradient_boosting': {'n_estimators': [50, 100], 'learning_rate': [0.01, 0.1]}
        }
        
        # Initialize and train ensemble model
        iljicevs = IljicevsModel(models, param_grids)
        
        # Check class balance
        iljicevs.check_class_balance(y_train)
        
        # Tune hyperparameters
        iljicevs.tune_hyperparameters(X_train, y_train)
        
        # Select the best performing models
        iljicevs.select_best_models(X_train, y_train)
        
        # Fit the selected models
        iljicevs.fit(X_train, y_train)
        
        # Evaluate the ensemble's accuracy on the test set
        accuracy = iljicevs.score(X_test, y_test)
        print(f"Ensemble accuracy: {accuracy}")
        
        # Display feature importance
        iljicevs.feature_importance()
        
        # Perform cross-validation with multiple metrics
        iljicevs.cross_validate_with_metrics(X_train, y_train, metrics=['accuracy', 'f1', 'roc_auc'])
        ```
        
        ### Class Balance Checking
        To avoid issues with unbalanced datasets, you can use the built-in method check_class_balance() to get a summary of the class distribution and suggestions for handling imbalances:
        ```python
        iljicevs.check_class_balance(y_train)
        ```
        
        ### Feature Importance
        To visualize the importance of features across models, use:
        ```python
        iljicevs.feature_importance()
        ```
        
        ### Cross-Validation with Metrics
        For more detailed model evaluation, you can use cross-validation with custom metrics:
        ```python
        iljicevs.cross_validate_with_metrics(X_train, y_train, metrics=['accuracy', 'f1', 'roc_auc'])
        ```
