The LION community

The LIONcommunity page contains mixed materials about machine learning and optimization (for prescriptive analytics) made available by our lab and by a growing community of active researchers and users, in particular slides related to the LIONbook, usage cases in selected application areas, tutorial movies, etc.
The LIONoso software by our lab can be useful to "dirty your hands" with real-world exercises in prescriptive analytics.
Feel free to contact us if you have interesting material which you would like to make available, or subscribe to our LIONlab newsletter (on the right) for short monthly updates about LIONcommunity activities.


For training and class usage

The selection of a subset of chapters corresponds to topics appropriate for an introductory course in LION (approximately 50 hours including exercises). The original Powerpoint version is also included so that you can adapt text and slides to your needs and personalize them.

LIONoso was used for the "Learning from Data" course by Caltech professor Yaser Abu-Mostafa at California Institute of Technology (Caltech), USA.

Exercises and use cases

Mixed materials from LION researchers and users

Warmup for using LIONoso as orchestrator.

The following is of interest for using LIONoso to "glue together" different components written in scripting or compiled languages (Python, C or C++, etc.), define complex processes and coordinate them, visualize results.
Essential for rapid prototyping and speeding up delivery of complex software processes.

Connecting components and "ruling them all" by LIONoso
One Ring to rule them all, One Ring to find them,
One Ring to bring them all and in the darkness bind them
In the Land of Mordor where the Shadows lie.

Using parametric tables
A flexible tool to generate data tables on the fly based on some input parameters. You have to try it to understand its power.

LIONoso orchestration of Java modules
The most efficient way to include an external model in LIONoso is to embed it within a Java package.

R language components in LIONoso

Connecting C# to LIONoso
How to write in C# and connect the component.

Use cases for "The LION way"

The following are meant to accompany the book with concrete and practical examples.

K nearest neighbors.

Learning with method (training and generalization).

Handwritten digit recognition with linear regression.

Digit recognition with CART trees and democratic forests.

Use cases for the Caltech course "Learning from Data"

The following are cases of tutorial nature.

The danger of overfitting.

Logistic regression for predicting heart disease.

Marketing automation for banks via SVM and cross-validation.

Mixed Usage Cases in Marketing, E-Commerce etc.

The following cases were developed mostly by users in marketing, e-commerce, finance, social networks.
