TaGra: TAbular data preprocessing to GRAph representation.

TaGra (Table to Graph)

TaGra is a comprehensive Python library designed to simplify the preprocessing of data, the construction of graphs from data tables, and the analysis of those graphs. It provides automated tools for handling missing data, scaling, encoding, and graph construction, making it easier for data scientists and researchers to focus on their analysis and results.

Features

• Automated Data Preprocessing: Clean and transform your data with options for handling missing values, scaling, encoding, and more.
• Graph Construction: Build graphs from data tables using various methods such as K-Nearest Neighbors (KNN), distance thresholds, and similarity measures.
• Graph Analysis: Perform statistical analysis on graphs, including degree distribution, centrality measures, community detection, and neighbor analysis.
• Visualization: Generate insightful visualizations to understand your data and graph structures.

Installation

To install TaGra, simply use pip:

pip install tagra

Quickstart

python3 examples/examples_usage.py -c examples/example_config.json

You can edit the option in examples/example_config.json and adapt them as you wish. The default option will produce a prepreocessing and a graph based on the moons dataset (SciKit Learn).

Usage

Data Preprocessing

from tagra.preprocessing import preprocess_dataframe

# Example usage
df = preprocess_dataframe(
    input_path='data.csv',
    output_path=None,
    numeric_columns=[],
    categorical_columns=[],
    unknown_column_action='infer',
    ignore_columns=[],
    numeric_threshold=0.05,
    numeric_scaling='standard',
    categorical_encoding='one-hot',
    nan_action='infer',
    nan_threshold=0.6,
    verbose=True,
    manifold_learning=None,
    manifold_dimension=2
)

Graph construction

from tagra.graph import construct_graph

Example usage

graph = construct_graph( data_path='data.csv', preprocessed_data_path=None, method='knn', k=5, output_path=None, verbose=True )

Graph Analysis

from tagra.analysis import analyze_graph

# Example usage
results = analyze_graph(
    graph_path='graph.pickle',
    degree_distribution=True,
    centrality_measures=['closeness', 'giant_connected_component'],
    community_detection='hierarchical',
    neighbor_analysis=True,
    attribute=None
)
