klib is a Python library for importing, cleaning, analyzing and preprocessing data. Future versions will include model creation and optimization to provide an end-to-end solution.

Installation

Use the package manager pip to install klib.

PyPI Version

pip install klib
pip install --upgrade klib

Alternatively, to install this package with conda run:

Conda Version

conda install -c conda-forge klib

Usage

import klib

klib.describe # functions for visualizing datasets
- klib.cat_plot() # returns a visualization of the number and frequency of categorical features.
- klib.corr_mat() # returns a color-encoded correlation matrix
- klib.corr_plot() # returns a color-encoded heatmap, ideal for correlations
- klib.dist_plot() # returns a distribution plot for every numeric feature
- klib.missingval_plot() # returns a figure containing information about missing values

klib.clean # functions for cleaning datasets
- klib.data_cleaning() # performs datacleaning (drop duplicates & empty rows/columns, adjust dtypes,...) on a dataset
- klib.convert_datatypes() # converts existing to more efficient dtypes, also called inside ".data_cleaning()"
- klib.drop_missing() # drops missing values, also called in ".data_cleaning()"
- klib.mv_col_handling() # drops features with a high ratio of missing values based on their informational content
- klib.pool_duplicate_subsets() # pools a subset of columns based on duplicate values without any loss of information

klib.preprocess # functions for data preprocessing (feature selection, scaling, ...)
- klib.train_dev_test_split() # splits a dataset and a label into train, optionally dev and test sets
- klib.feature_selection_pipe() # provides common operations for feature selection
- klib.num_pipe() # provides common operations for preprocessing of numerical data
- klib.cat_pipe() # provides common operations for preprocessing of categorical data

Examples

Find all available examples with added descriptions here.

klib.missingval_plot(df) # default representation of missing values in a DataFrame, plenty of settings are available

Corr Plot Example

klib.corr_plot(df, split='pos') # displaying only positive correlations

Corr Plot Example

klib.corr_plot(df, target='air_time') # default representation of correlations with the feature column

Target Corr Plot Example

klib.cat_plot(data, top=4, bottom=4) # representation of the 4 most & least common values in each categorical column

Cat Plot Example

Further examples, as well as applications of the functions in klib.clean() can be found here.
