Program Code – Project: Exploring Machine Learning Models with The What-If Tool

# Importing necessary libraries
import numpy as np
import pandas as pd
from sklearn.model_selection import train_test_split
from sklearn.ensemble import RandomForestClassifier
from witwidget.notebook.visualization import WitConfigBuilder
from witwidget.notebook.visualization import WitWidget

# Load a dataset (For illustration, we're using the Iris dataset)
from sklearn.datasets import load_iris
iris_data = load_iris()

# Splitting the dataset into training and testing sets
X_train, X_test, y_train, y_test = train_test_split(iris_data['data'], iris_data['target'], test_size=0.2, random_state=42)

# Training a RandomForestClassifier
model = RandomForestClassifier(n_estimators=100, random_state=42)
model.fit(X_train, y_train)

# Preparing the test data for the What-If Tool
test_examples = np.hstack((X_test, y_test.reshape(-1, 1)))

# Configuring the What-If Tool to use the trained model and the test data
config_builder = WitConfigBuilder(test_examples.tolist(), iris_data['feature_names'] + ['target']).set_model_type('classification').set_label_vocab(iris_data['target_names'].tolist())
WitWidget(config_builder, height=800)

Expected Code Output:

When this code snippet is executed in a Jupyter notebook environment, it won’t output traditional text or numerical results. Instead, it will display an interactive interface provided by the What-If Tool (WIT). This interface will enable users to probe and visualize the Random Forest model’s performance on the Iris dataset interactively. Users can alter input feature values for test data points and observe model predictions, and even compare performance metrics across subsets of the data.

Code Explanation:

• Library Imports: We begin by importing necessary Python libraries and functions. The sklearn library is used for machine learning model training and data splitting. The witwidget library provides visualization capabilities needed for deploying the What-If Tool.
• Data Preparation: The Iris dataset, a common dataset for classification tasks, is loaded and split into training and testing subsets. This dataset includes 4 features for predicting one of three Iris flower species.
• Model Training: A RandomForestClassifier, a flexible and powerful machine learning model, is trained using the training subset of the Iris dataset.
• What-If Tool Configuration:
  • The testing subset is prepared to be analyzed with the What-If Tool by creating a combined array of features and the target labels.
  • The WitConfigBuilder function is then used to configure the visualization. This includes specifying the test data (test_examples), the model type (‘classification’), and the label vocabulary (names of the Iris species).
  • Finally, WitWidget is used to create and display the interactive What-If Tool interface within the Jupyter notebook environment.

The overall objective of this code snippet is to provide a practical and interactive exploration of machine learning model behaviors using the What-If Tool. Users can deeply understand how the model makes predictions and under what circumstances its performance might vary, which is invaluable for model evaluation and improvement.
