pytorch-lattice 0.2.0

A PyTorch Implementation Of Lattice Modeling Techniques

Getting Started with PyTorch Lattice

A PyTorch implementation of constrained optimization and modeling techniques

• Transparent Models: Glassbox models to provide increased interpretability and insights into your ML models.
• Shape Constraints: Embed domain knowledge directly into the model through feature constraints.
• Rate Constraints (Coming soon...): Optimize any PyTorch model under a set of constraints on rates (e.g. FPR < 1%). Rates can be calculated both for the entire dataset as well as specific slices.

Installation

Install PyTorch Lattice and start training and analyzing calibrated models in minutes.

$ pip install pytorch-lattice

Quickstart

Step 1. Import the package

First, import the PyTorch Lattice library:

import pytorch_lattice as pyl

Step 2. Load data and fit a classifier

Load the UCI Statlog (Heart) dataset. Then create a base classifier and fit it to the data. Creating the base classifier requires only the feature names.

X, y = pyl.datasets.heart()
clf = pyl.Classifier(X.columns).fit(X, y)

Step 3. Plot a feature calibrator

Now that you've trained a classifier, you can plot the feature calibrators to better understand how the model is understanding each feature.

pyl.plots.calibrator(clf.model, "thal")

Step 4. What's Next?

• Check out the Concepts section to dive deeper into the library and the core features that make it powerful, such as calibrators and shape constraints.
• You can follow along with more detailed walkthroughs to get a better understanding of how to utilize the library to effectively model your data. You can also take a look at code examples in the repo.
• The API Reference contains full details on all classes, methods, functions, etc.
