class KMEngine(data, column, test_ratio=0.2)

---

KMEngine (Karthik's Model Engine) is a versatile tool designed to streamline machine learning model training, evaluation, and customization. With support for both regression and classification tasks, Kmodel_engine offers an automated workflow that includes data preprocessing, feature selection, exploratory data analysis (EDA), model training, and metric evaluation. This class integrates an array of popular machine learning models from libraries like Scikit-Learn, XGBoost, and LightGBM. Additionally, it facilitates model parameter customization, empowering users to efficiently build, assess, and refine machine learning models tailored to their specific datasets and tasks. As of now this class cannot remove outliers, to remove them use O_sieve or IsolationForest

Features

• Supports both regression and classification tasks
• Integrates a wide range of machine learning models from popular libraries such as Scikit-Learn, XGBoost, LightGBM, and more
• Performs automated data preprocessing including missing value imputation, scaling, and one-hot encoding
• Allows for exploratory data analysis (EDA) through YData Profiling
• Provides various evaluation metrics including accuracy, F1-score, precision, recall, ROC AUC, R-squared, adjusted R-squared, mean absolute error (MAE), and root mean squared error (RMSE)
• Supports custom parameter tuning for models

---

Parameters:

• data: dataframe

  • The data on which the evalution of models should occur.

• column: str

  • Target column, the dependent variable.

• test_ratio: float, default=0.2

  • The conventional training and testing split ratio.

Installation

pip install KMEngine

Usage

EDA (EXtrapolatory Data Analysis)

import pandas as pd
from fluid_domain.art import KMEngine
# Reading a dataset using pandas.
df=pd.read_csv('tested.csv')
engine=KMEngine(df,'Survived')
eda=engine.EDA()
# EDA done. Check your working directory for the html file. 
# Produces an html file with the name 'KME_data_report.html' in the working directory.

Classification:

# Reading a dataset using pandas.
df=pd.read_csv('tested.csv')
engine=KMEngine(df,'Survived')
result=engine.super_learning()
print(result)

Model saving (General Model)

# Reading a dataset using pandas.
df=pd.read_csv('tested.csv')

Model saving (Custom Model)

The specified custom model will overwrite the existing model in the model dictionary, for space conservation purposes.
