batabyal 1.0.2

A lightweight Python package for Machine Learning utilities

Package: batabyal

---

batabyal is a lightweight Python package for Machine Learning utilities that provides:

• cleaning_module - A CSV data cleaning module
• trainer_kit - ML module for classification problems

Installation

---

Use the below command in the terminal

pip install batabyal

Importation

---

Import a specific thing or the entire module whatever is required

from batabyal import cleaning_module as cm
from batabyal.trainer_kit import TransformedTargetClassifier, autofit_classification_model

Usage

---

1. cleaning_module: It provides only one function clean_csv used for cleaning .csv datasets efficiently

cm.clean_csv('filename.csv', numericData, charData, True, True) 
#structure: clean_csv(file, numericData, charData, fill, case_sensitivity=False, dummies=None) -> pd.DataFrame
#If `fill==True`, it fills NaN in numeric columns with its mean. 
#if `case_sensitivity=True`, it will lowercase all labelled values.
#`dummies` are the list of values to replace with NaN before cleaning.

2. trainer_kit: It provides one wrapper class TransformedTargetClassifier for encoding and inversely transforming predictions to the original label and one function autofit_classification_model for autofitting classification models with the best algorithm and hyperparameters based on roc_auc_ovr_weighted score

model = TransformedTargetClassifier(classifier=svc, transformer=labelEncoder)
#let labelencoder and svc are from sklearn 
#you can now use model.fit() , model.predict() with raw labelled data, it will automate the encoding internally for training and prediction
#And model.predict() will return the original label by inversely transforming the encoded numbers back internally 

model, accuracy, algorithm_name = autofit_classification_model(x, y, "numeric", 3)
#structure: autofit_classification_model(x:pd.DataFrame, y:pd.DataFrame, x_type:Literal["numeric", "categorical", "mixed"], n_splits:int, cat_features:list[str]=[], whitelisted_algorithms:list[Literal["LogisticRegression", "DecisionTree", "RandomForest", "GaussianNB", "BernoulliNB", "CategoricalNB", "CatBoost", "XGBoost", "Ripper", "SVC", "KNN"]]|Literal["auto"]="auto", enable_votingClassifier:bool=True, random_state:int|None=42, verbosity:bool=True) -> tuple[ClassifierMixin, float, str]
