ADCL-Automatic-Data-Cleaning Project

Overview

ADCL-Automatic-Data-Cleaning is a Python package designed to facilitate automated data cleaning, particularly leveraging deep learning techniques for preprocessing tasks essential in data science and machine learning workflows.

Features

• Data Preprocessing: Standardize, normalize, and format your data for machine learning models.
• Missing Value Imputation: Implements various techniques for handling missing data in both cross-sectional and time-series datasets.
• Outlier Detection: Identifies and manages outliers using multiple strategies, improving the robustness of your models.
• Encoding and Transformation: Converts categorical data into a machine-readable format using various encoding techniques.
• Time Series Handling: Special functions for processing time-dependent data.

Repository Structure

• data_preprocessing/: Contains the core library file data_preprocessing.py with all preprocessing functions.
• examples/: Includes example_usage.ipynb, a Jupyter notebook demonstrating how to use the preprocessing functions.
• missing_values_imputation_test/: Contains notebooks for testing missing value imputation across different data types.
• outlier_detection_test/: Contains notebooks for testing outliers detection across different data types.
• LICENSE: The project is open-sourced under the MIT license.

Installation

To install ADCL directly from PyPI, run the following command:

pip install adcl

Usage

Data Preprocessing

You can preprocess your datasets by importing functions from data_preprocessing.py. For example:

from adcl import process_data
filepath = 'path_to_your_data.csv'
df_train, df_test, y_column_name, date_col = process_data(train_input=filepath)

Missing Value Handling

Handle missing values by choosing an appropriate method from the library. An example usage for time series data:

from adcl import missing_values_handling
X_train_mis, X_test_mis = missing_values_handling(df_train=X_train, df_test=X_test, datetime_col=date_col, imputation_method='auto')

Outlier Detection

Detect Outliers by choosing an appropriate method from the library. An example usage for time series data:

from adcl import outlier_detection
X_train_out, X_test_out = outlier_detection(X_train=X_train, X_test=X_test, datetime_col=date_col
                                    , method='auto', nu=0.05, kernel='rbf', gamma='scale'
                                    , n_neighbors=20, contamination='auto', n_estimators=100
                                    , encoding_dim=8, epochs=50, batch_size=32
                                    , window_size=20, dtw_window=None)

Categorical Variables Encoding

Encode categorical variables by choosing an appropriate method from the library. An example usage for time series data:

from adcl import encode_data
X_train_enc, X_test_enc = encode_data(df_train=X_train, df_test=X_test, y_column_name,
                encoding_method='label', nu=0.05, kernel='rbf', gamma='scale',
                n_neighbors=20, contamination='auto', n_estimators=100,
                encoding_dim=8, epochs=50, batch_size=32)
