EazyML Responsible-AI: XAI

eazyml-xai is a python package designed to make machine learning predictions more transparent and interpretable. It provides human-readable explanations for predictions.

Features

• Local Feature Importance: Get insights into the most impactful features influencing the predicted target variable.
• Explanations: Explains the reason behind the predicted target variable.
• Explainability Score: Enhance the reliability of explanations with an explainability score.

eazyml-xai is a key tool for building trust in AI systems by providing clear, actionable explanations.

Installation

To use the explainable ai, ensure you have Python installed on your system.

User installation

The easiest way to install EazyML Explainable AI is using pip:

pip install -U eazyml-xai

Dependencies

This package requires:

• pandas
• scikit-learn
• werkzeug
• Unidecode
• pydot
• numpy
• pyyaml
• xgboost

Usage

Example 1 - Fetching explanations with the EazyML model.

Imports

from eazyml_xai import ez_init, ez_explain

Initialize and Read Data

# Initialize the EazyML automl library.
_ = ez_init()

# Load training data (Replace with the correct data path).
train_data_path = "path_to_your_training_data.csv"
train = pd.read_csv(train_data_path)

# Load test data (Replace with the correct data path).
test_data_path = "path_to_your_test_data.csv"
test = pd.read_csv(test_data_path)

Fetch Explanations

# Define the outcome (target variable)
outcome = "target"  # Replace with your target variable name

# Build EazyML predictive models
build_options = {'model_type': 'predictive'}
build_resp = ez_build_model(train, outcome=outcome, options=build_options)

# Use model_info from ez_build_model response
model_info = build_resp["model_info"]

# Customize options for fetching explanations
xai_options = {"record_number": [1, 2, 3]}

# To fetch the explanations
xai_response = ez_explain(train, outcome, test_data_path, model_info, options=xai_options)

# xai_response is a dictionary object with following keys.
# print (xai_response.keys())
# dict_keys(['success', 'message', 'explanations'])

# reponse object contains a dictionary with explanations for the user specified record numbers. 

Example 2 - Fetching explanations with your model and EazyML preprocessing.

Imports

from eazyml_xai import ez_init, ez_explain, create_onehot_encoded_features, ez_get_data_type

Initialize and Read Data

# Initialize the EazyML automl library.
_ = ez_init()

# Load training data (Replace with the correct data path).
train_data_path = "path_to_your_training_data.csv"
train = pd.read_csv(train_data_path)

# Define input features (X) and target variable (y)
y = train[outcome]
X = train.drop(outcome, axis=1)

# Load test data (Replace with the correct data path).
test_data_path = "path_to_your_test_data.csv"
test = pd.read_csv(test_data_path)

Fetch Explanations

# Define the outcome (target variable)
outcome = "target"  # Replace with your target variable name

# Get data type of features
type_df = ez_get_data_type(train, outcome)

# List of categorical columns
cat_list = type_df[type_df['Data Type'] == 'categorical']['Variable Name'].tolist()
cat_list = [ele for ele in cat_list if ele != outcome]

# Create one-hot encoded features
train = create_onehot_encoded_features(train, cat_list)

# Define your model object (replace with any model of your choice)
model_info = <YourModelClass>(<parameters>)  # e.g., RandomForestClassifier(), LogisticRegression(), etc.

# Train your model object
model_info.fit(X, y)

# Customize options for fetching explanations
xai_options = {"record_number": [1, 2, 3]}

# To fetch the explanations
xai_response = ez_explain(train, outcome, test_data_path, model_info, options=xai_options)

# xai_response is a dictionary object with following keys.
# print (xai_response.keys())
# dict_keys(['success', 'message', 'explanations'])

# reponse object contains a dictionary with explanations for the user specified record numbers. 

Example 3 - Fetching explanations with your model and preprocessing.

Imports

from eazyml_xai import ez_init, ez_explain

Initialize and Read Data

# Initialize the EazyML automl library.
_ = ez_init()

# Load training data (Replace with the correct data path).
train_data_path = "path_to_your_training_data.csv"
train = pd.read_csv(train_data_path)

# Define input features (X) and target variable (y)
y = train[outcome]
X = train.drop(outcome, axis=1)

# Load test data (Replace with the correct data path).
test_data_path = "path_to_your_test_data.csv"
test = pd.read_csv(test_data_path)

Fetch Explanations

# Define the outcome (target variable)
outcome = "target"  # Replace with your target variable name

# Implement your preprocessing steps within a custom preprocessor class and define it
# (Replace <YourPreprocessorClass> with the specific preprocessor class you're using)
preprocessor = <YourPreprocessorClass>(<parameters>)  # Example: StandardScaler(), CustomPreprocessor()

# Fit the preprocessor on your dataset
preprocessor.fit(X, y)

# Define your model object (replace with any model of your choice)
model_info = <YourModelClass>(<parameters>)  # e.g., RandomForestClassifier(), LogisticRegression(), etc.

# Train your model object
model_info.fit(X, y)

# Customize options for fetching explanations
xai_options = {"record_number": [1, 2, 3], "preprocessor", preprocessor}

# To fetch the explanations
xai_response = ez_explain(train_data_path, outcome, test_data_path, model_info, options=xai_options)

# xai_response is a dictionary object with following keys.
# print (xai_response.keys())
# dict_keys(['success', 'message', 'explanations'])

# reponse object contains a dictionary with explanations for the user specified record numbers.
