xplainable

Real-time explainable machine learning for business optimisation

Xplainable makes tabular machine learning transparent, fair, and actionable.

Why Was Xplainable Created?

In machine learning, there has long been a trade-off between accuracy and explainability. This drawback has led to the creation of explainable ML libraries such as Shap and Lime which make estimations of model decision processes. These can be incredibly time-expensive and often present steep learning curves making them challenging to implement effectively in production environments.

To solve this problem, we created xplainable. xplainable presents a suite of novel machine learning algorithms specifically designed to match the performance of popular black box models like XGBoost and LightGBM while providing complete transparency, all in real-time.

Simple Interface

You can interface with xplainable either through a typical Pythonic API, or using a notebook-embedded GUI in your Jupyter Notebook.

Models

Xplainable has each of the fundamental tabular models used in data science teams. They are fast, accurate, and easy to use.

Multi-Class Classification	✅	🔜

Installation

You can install the core features of xplainable with:

pip install xplainable

to use the xplainable gui in a jupyter notebook, install with:

pip install xplainable[gui]

Getting Started

Basic Example

import xplainable as xp
from xplainable.core.models import XClassifier
import pandas as pd
from sklearn.model_selection import train_test_split

# Load data
data = xp.load_dataset('titanic')

X, y = data.drop(columns=['Survived']), data['Survived']

X_train, X_test, y_train, y_test = train_test_split(
     X, y, test_size=0.25, random_state=42)

# Train a model
model = XClassifier()
model.fit(X_train, y_train)

# Explain the model
model.explain()

Features

Xplainable helps to streamline development processes by making model tuning and deployment simpler than you can imagine.

Preprocessing

We built a comprehensive suite of preprocessing transformers for rapid and reproducible data preprocessing.

Feature	Python API	Jupyter GUI
Data Health Checks	✅	✅
Transformers Library	✅	✅
Preprocessing Pipelines	✅	✅
Pipeline Persistance	✅	✅

Using the API

from xplainable.preprocessing.pipeline import XPipeline
from xplainable.preprocessing import transformers as xtf

pipeline = XPipeline()

# Add stages for specific features
pipeline.add_stages([
    {"feature": "age", "transformer": xtf.Clip(lower=18, upper=99)},
    {"feature": "balance", "transformer": xtf.LogTransform()}
])

# add stages on multiple features
pipeline.add_stages([
    {"transformer": xtf.FillMissing({'job': 'mode', 'age': 'mean'})},
    {"transformer": xtf.DropCols(columns=['duration', 'campaign'])}
])

# Fit and transform the data
train_transformed = pipeline.fit_transform(train)

# Apply transformations on new data
test_transformed = pipeline.transform(test)

Using the GUI

pp = xp.Preprocessor()

pp.preprocess(train)

Modelling

Xplainable models can be developed, optimised, and re-optimised using Pythonic APIs or the embedded GUI.

Feature	Python API	Jupyter GUI
Classic Vanilla Data Science APIs	✅	-
AutoML	✅	✅
Hyperparameter Optimisation	✅	✅
Partitioned Models	✅	✅
Rapid Refitting (novel to xplainable)	✅	✅
Model Persistance	✅	✅

Using the API

import xplainable as xp
from xplainable.core.models import XClassifier
from xplainable.core.optimisation.bayesian import XParamOptimiser
from sklearn.model_selection import train_test_split
import pandas as pd

# Load your data
data = xp.load_dataset('titanic')

# note: the data requires preprocessing, so results may be poor
X, y = data.drop('Survived', axis=1), data['Survived']

X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.2)

# Optimise params
opt = XParamOptimiser(metric='roc-auc')
params = opt.optimise(X_train, y_train)

# Train your model
model = XClassifier(**params)
model.fit(X_train, y_train)

# Predict on the test set
y_pred = model.predict(X_test)

# Explain the model
model.explain()

Using the GUI

model = xp.classifier(train)

Rapid Refitting

Fine tune your models by refitting model parameters on the fly, even on individual features.

Using the API

new_params = {
            "features": ['Age'],
            "max_depth": 6,
            "min_info_gain": 0.01,
            "min_leaf_size": 0.03,
            "weight": 0.05,
            "power_degree": 1,
            "sigmoid_exponent": 1,
            "x": X_train,
            "y": y_train
}

model.update_feature_params(**new_params)

Using the GUI
