onelineml 0.2.2

A tool for creating machine learning pipelines with custom preprocessing and model selection

onelineml

onelineml is a Python package designed to simplify the process of creating machine learning pipelines. It allows you to easily handle data preprocessing, model selection, and model evaluation with a few simple function calls.

Features

• Customizable missing value handling for numerical and categorical features.
• Support for multiple machine learning models including:
  • Random Forest
  • Logistic Regression
  • Decision Tree
  • Support Vector Machine (SVM)
  • K-Nearest Neighbors (KNN)
  • Gradient Boosting Classifier (XGBoost)
  • Naive Bayes
• Easy to integrate into your machine learning workflows.
• Built-in model evaluation with accuracy score and classification report.

Installation

You can install onelineml directly from PyPI (if published) or locally from the source.

From PyPI

pip install onelineml

From Source

To install onelineml from the source, follow these steps:

1. Clone the repository:

   git clone https://github.com/gaharivatsa/easyml.git
   

2. Navigate to the project directory:

   cd onelineml
   

3. Install the package:

   pip install .
   

Usage

Here's a step-by-step guide on how to use onelineml in your projects.

1. Import the Package

Start by importing the create_ml_pipeline function from the onelineml package.

from onelineml import create_ml_pipeline

2. Prepare Your Data

Ensure your dataset is in a CSV format and includes a target column that you want to predict.

# Example: Load your dataset
dataset = 'path_to_your_dataset.csv'
target = 'target_column_name'

3. Create and Run the Pipeline

Use the create_ml_pipeline function to build and run the pipeline. You can specify the missing value handling strategies, the model, and any model-specific parameters.

pipeline = create_ml_pipeline(
    numerical_na_method='mean',            # Strategy for imputing missing values in numerical columns
    categorical_na_method='most_frequent', # Strategy for imputing missing values in categorical columns
    model_name='knn',                      # Choose the model (e.g., 'knn', 'random_forest', etc.)
    model_params={'n_neighbors': 5},       # Model-specific parameters
    dataset=dataset,                       # Path to your dataset
    target=target,                         # Target column name
    splitting_ratio=0.25                   # Ratio for splitting the dataset into training and testing sets
)

4. View Results

The function will output the accuracy and classification report after training the model.

5. Save the Pipeline

The trained pipeline is automatically saved as a .pkl file for future use.

# Example: Load and use the saved pipeline
import joblib

loaded_pipeline = joblib.load('knn_pipeline.pkl')

6. Customize Further

Feel free to customize the pipeline further by adjusting the model parameters, trying different models, or even extending the functionality by modifying the source code.
