classifierAgent 1.1.1

A Python package for performing classification on datasets.

classifierAgent: Machine Learning Classification Python Package

Overview

This Python package provides a comprehensive solution for performing classification tasks using various popular machine learning algorithms. It allows you to read a dataset, preprocess it, train multiple classifiers, perform hyperparameter tuning, and visualize model performance. Additionally, it provides options for scaling data, saving trained models, and customizing the output display.

Features

1. Classification Algorithms:

   • Logistic Regression
   • K-Nearest Neighbors
   • Decision Tree
   • Random Forest
   • Gradient Boosting
   • Support Vector Classifier
   • Gaussian Naive Bayes
   • Bernoulli Naive Bayes

2. Advanced Functionality:

   • Data Scaling: Options for Min-Max Scaling or Standard Normalization.
   • Hyperparameter Tuning: Option to perform Grid Search for finding the best model parameters.
   • Model Persistence: Save and load trained models using joblib.
   • Visualization: Option to plot confusion matrices and detailed classification reports.
   • Cross-Validation: Evaluate models using cross-validation scores.
   • Configurable Outputs: Options to control the display of confusion matrices and classification reports.

3. Results:

   • Returns a DataFrame with model names, accuracy, F1-score, and optionally the best hyperparameters.

Parameters

The package takes the following parameters as input:

• dataset: Path to the CSV or Excel dataset file or a pandas DataFrame.
• output_column: Name of the output column containing the target variable.
• train_test_ratio: Ratio in which the dataset is divided into train and test splits (must be between 0 and 1).
• scaling_method (optional): Method to scale the data ('minmax' or 'normalize').
• perform_grid_search (optional): Whether to perform grid search for hyperparameter tuning (default is False).
• save_models (optional): Whether to save trained models to disk (default is False).
• show_confusion_matrix (optional): Whether to display confusion matrix plots (default is False).
• show_classification_report (optional): Whether to print classification reports (default is False).

Installation

Make sure you have Python installed on your system. You can install the package using pip:

pip install classifierAgent

Usage

Here's an example of how to use the package:

from classifierAgent import classifierAgent

dataset_path = "sampleFile.csv"
output_column = "Outcome"
train_test_ratio = 0.25
scaling_method = 'minmax'  # Choose 'minmax' or 'normalize'
perform_grid_search = True  # Whether to perform grid search
save_models = True  # Whether to save models
show_confusion_matrix = True  # Whether to plot the confusion matrix
show_classification_report = True  # Whether to print the classification report

results = classifierAgent(dataset_path, output_column, train_test_ratio, scaling_method, perform_grid_search, save_models, show_confusion_matrix, show_classification_report)
print(results)

Example Output

The output is a DataFrame that looks like this:

Classifier	Accuracy	F1-Score	Best Parameters
KNeighborsClassifier	0.78	0.76	{'n_neighbors': 5, 'weights': 'uniform'}
LogisticRegression	0.80	0.79	{'C': 0.1, 'solver': 'liblinear'}
DecisionTreeClassifier	0.72	0.70	{'criterion': 'entropy', 'max_depth': 20}
RandomForestClassifier	0.85	0.84	{'n_estimators': 200, 'max_depth': 20}
GradientBoostingClassifier	0.83	0.82	{'n_estimators': 200, 'learning_rate': 0.1}
SVC	0.81	0.80	{'C': 1, 'kernel': 'rbf'}
GaussianNB	0.75	0.73	{}
BernoulliNB	0.73	0.72	{}

Publishing to PyPI

Automated Publishing with GitHub Actions

To automate the publishing of your package to PyPI, GitHub Actions is setup. This allows to push updates to PyPI whenever changes are made to the main branch.

Setting Up GitHub Actions

1. Add Your PyPI Token to GitHub Secrets:

   • Go to your repository settings.
   • Navigate to "Secrets and variables" > "Actions".
   • Add a new secret with the name PYPI_TOKEN and paste your PyPI token as the value.

2. Create a GitHub Actions Workflow File:

   • Add a .github/workflows/publish.yml file to your repository with the following content:

This setup will automatically build and publish your package to PyPI whenever you push changes to the main branch. Make sure to test your workflow to ensure that everything works as expected.

Notes

• The package is actively developed and may receive updates.
• The project is developed with Python version 3.10.
