SlickML🧞: Slick Machine Learning in Python

SlickML is an open-source machine learning library written in Python aimed at accelerating the experimentation time for a ML application. Data Scientist tasks can often be repetitive such as feature selection, model tuning, or evaluating metrics for classification and regression problems. SlickML provides Data Scientists with a toolbox to quickly prototype solutions for a given problem with minimal code.

🛠 Installation

To begin with, install Python version >=3.8,<3.10 and simply run 🏃‍♀️ :

pip install slickml

📣 Please note that a working Fortran Compiler (gfortran) is also required to build the package. If you do not have gcc installed, the following commands depending on your operating system will take care of this requirement.

# Mac Users
brew install gcc

# Linux Users
sudo apt install build-essential       

🐍 Python Virtual Environments

In order to avoid any potential conflicts with other installed Python packages, it is recommended to use a virtual environment, e.g. python poetry, python virtualenv, pyenv virtualenv, or conda environment. Our recommendation is to use python-poetry 🥰 for everything 😁.

📌 Quick Start

✅ An example to quickly run a Feature Selection pipeline with embedded Cross-Validation and Feature-Importance visualization:

from slickml.feautre_selection import XGBoostFeatureSelector
xfs = XGBoostFeatureSelector()
xfs.fit(X, y)

xfs.plot_cv_results()

xfs.plot_frequency()

✅ An example to quickly find the tuned hyper-parameter with Bayesian Optimization:

from slickml.optimization import XGBoostClassifierBayesianOpt
xbo = XGBoostClassifierBayesianOpt()
xbo.fit(X_train, y_train)

best_params = xbo.get_best_params()
best_params

{"colsample_bytree": 0.8213916662259918,
 "gamma": 1.0,
 "learning_rate": 0.23148232373451072,
 "max_depth": 4,
 "min_child_weight": 5.632602921054691,
 "reg_alpha": 1.0,
 "reg_lambda": 0.39468801734425263,
 "subsample": 1.0
 }

✅ An example to quickly train/validate a XGBoostCV Classifier with Cross-Validation, Feature-Importance, and Shap visualizations:

from slickml.classification import XGBoostCVClassifier
clf = XGBoostCVClassifier(params=best_params)
clf.fit(X_train, y_train)
y_pred_proba = clf.predict_proba(X_test)

clf.plot_cv_results()

clf.plot_feature_importance()

clf.plot_shap_summary(plot_type="violin")

clf.plot_shap_summary(plot_type="layered_violin", layered_violin_max_num_bins=5)

clf.plot_shap_waterfall()

✅ An example to train/validate a GLMNetCV Classifier with Cross-Validation and Coefficients visualizations:

from slickml.classification import GLMNetCVClassifier
clf = GLMNetCVClassifier(alpha=0.3, n_splits=4, metric="roc_auc")
clf.fit(X_train, y_train)
y_pred_proba = clf.predict_proba(X_test)

clf.plot_cv_results()

clf.plot_coeff_path()

✅ An example to quickly visualize the binary classification metrics based on multiple thresholds:

from slickml.metrics import BinaryClassificationMetrics
clf_metrics = BinaryClassificationMetrics(y_test, y_pred_proba)
clf_metrics.plot()

✅ An example to quickly visualize some regression metrics:

from slickml.metrics import RegressionMetrics
reg_metrics = RegressionMetrics(y_test, y_pred)
reg_metrics.plot()
