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

Certainly! Let’s dive into a Python program designed to explore Machine Learning models using Google’s What-If Tool (WIT). This tool allows interactive probing and visualization of machine learning model predictions, directly within your Jupyter environment. For our purposes, imagine we’ve trained a basic classification model on some dataset (e.g., for predicting whether an email is spam or not). We’ll focus on integrating WIT to interactively query this model.

# Required Libraries
import numpy as np
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

# Sample Data Generation: email features (length, keyword_count, has_attachment) and labels (spam: 1, not spam: 0)
np.random.seed(42)  # For reproducibility
features = np.random.rand(100, 3) * 100
labels = np.where(np.mean(features, axis=1) > 50, 1, 0)

# Splitting dataset into training and test partitions
X_train, X_test, y_train, y_test = train_test_split(features, labels, test_size=0.2, random_state=42)

# Model Training: A simple RandomForest Classifier
model = RandomForestClassifier(n_estimators=50)
model.fit(X_train, y_train)

# Setting up the What-If Tool (WIT)
test_examples = np.hstack((X_test, y_test.reshape(-1, 1)))

# Building the WIT config: pointing to our test examples and model
config_builder = WitConfigBuilder(test_examples.tolist()).set_estimator_and_feature_names(
    model, ['length', 'keyword_count', 'has_attachment'])

# Displaying the What-If Tool
WitWidget(config_builder, height=800)

Expected Code Output:

Due to the interactive nature of the What-If Tool, the code does not produce a static output in a text format. When executed in a Jupyter notebook, it renders the What-If Tool interface, displaying the test data examples along with the option to interactively query the model, tweak example features, and visualize the model’s predictions and their explanations.

Code Explanation:

1. Library Imports: We begin by importing necessary libraries. We’re using numpy for data manipulation, train_test_split and RandomForestClassifier from scikit-learn for data partitioning and model training respectively, and classes from witwidget.notebook.visualization for visualizing our model with the What-If Tool.
2. Data Generation: For demonstration, a synthetic dataset is generated consisting of 100 email records, each with 3 features – ‘length’, ‘keyword_count’, and ‘has_attachment’. The label (spam: 1, not spam: 0) is determined by a simple rule over the average of these features.
3. Model Training: A RandomForest Classifier is trained on 80% of the generated dataset. It’s a simple model choice for classification tasks.
4. Setup of The What-If Tool (WIT): We use our test set (X_test and y_test) to seed WIT. This involves merging the features and labels into a single dataset (test_examples) for the tool to parse.
5. WIT Configuration and Initialization: The WitConfigBuilder class is used to configure how WIT will interface with the provided data and our trained model. Here, we specify the test_examples, the model itself, and the feature names. Finally, the WitWidget class is invoked with this configuration to render the interactive WIT interface in the Jupyter notebook.

The What-If Tool offers a powerful interactive interface for probing machine learning models. It allows users to manually adjust feature values of test examples and observe how those adjustments affect model predictions, thereby providing insights into model behavior and potential biases.
