Illinois Structured Learning Package v1.0.0

Illinois Structured Learning Package (Illinois-SL) is a general purpose JAVA library for performing structured learning. It houses learning algorithms like averaged Structured Perceptron and Structured SVM with L2-Loss, and provides a minimal interface for your structured learning needs. The training algorithm employed for training SSVM is dual coordinate descent(DCD), which has been proven to have very good convergence properties. Illinois-SL comes with an efficient implementation of DCD with support for multi-threading. Illinois-SL provides a simple and neat framework for developing applications using structured prediction models.

Example Usage

We provide detailed examples in an accompanying package at illinois-sl-examples.

License

The Illinois Structured Learning Package is available under a Research and Academic use license. For more details, view the license file LICENSE.

System requirements

The Illinois Structured Learning Package was developed on and for GNU/Linux, specifically CENTOS (2.6.18-238.12.1.el5) and Scientific Linux (2.6.32-279.5.2.el6.x86_64). There are no guarantees for running it under any other operating system, but we hope it should run on a Linux OS without any issues.

We assume that the package is installed on a machine with sufficient memory. The actual requirement of the memory depends on the task and size of the learning problem.

NOTE: When running your project, if working with a large dataset, you may need to invoke your project using the -Xmx1G and -XX:MaxPermSize=1G JVM command line parameters.
