Data Summary

The Data Summary panel provides an overview of your dataset, offering statistical insights, data quality metrics, and feature-level analysis.

Initialize the Panel

To create and initialize the Data Summary panel, use:

# Load the Experiment and view the data summary
from modeva import Experiment
exp = Experiment(name='Demo-SimuCredit')
exp.data_summary()

Workflow

Step 1: Load and Select Dataset

  1. Choose a dataset from the dropdown (e.g., Demo-SimuCredit).

  2. Select a data split (e.g., main, train, test).

Step 2: Review Dataset Overview

The Overview Tab displays high-level statistics about the dataset:

  • Data Shape: Total number of rows and columns.

  • Features: Count of numerical, categorical, and mixed columns.

  • Data Quality Metrics: Percentage of missing cells, duplicate records, and infinite values.

Step 3: Analyze Numerical Features

Switch to the Numeric Tab to explore numerical features (e.g., Mortgage, Balance).

  1. View Statistics: View the statistics including the number of missing values, mean, first quartile (Q1), median (Q2), third quartile (Q3), minimum, and maximum values.

  2. View Distribution: Click a row in the table to view its distribution.

  3. Customize the Plot:

    • Choose between a Histogram or Density Plot.

    • Adjust the number of bins (Only for histogram).

Step 4: Analyze Categorical Features

Switch to the Categorical Tab to analyze non-numeric features (e.g., Gender, Race).

  1. View Statistics: View the statistics including the number of missing values, number of unique values, and most common category information.

  2. View Distribution: Click a row to display the bar chart to view the distribution of the feature.

Step 5: Adjust Data Types (If Necessary)

Click the |settings_icon| to reclassify features as numerical or categorical using the radio buttons.

After adjustment, the Data Summary panel updates to reflect the new feature types.

Step 6: Save and Export Results

Click the |register_icon| to save plots and statistics (if configured). All registered outputs are stored in mlflow for future reference.
