BayesiaLab is suite of powerful Artificial Intelligence programs that provide researchers a comprehensive “lab” environment for machine learning, knowledge modeling, analytics, simulation, and optimization — all based on the Bayesian network paradigm.

  • BayesiaLab

    BayesiaLab is a powerful desktop application (Windows/Mac/Unix) for knowledge management, data mining, analytics, predictive modeling and simulation — all based on the paradigm of Bayesian networks. Bayesian networks have become a very powerful tool for deep understanding of very complex, high-dimensional problem domains, ranging from bioinformatics to marketing science.

    BayesiaLab is the world’s only comprehensive software package for generating, manipulating and analyzing Bayesian networks. Analysts and researchers around the world, including Bayesia’s strategic partner P&G, have embraced BayesiaLab to gain unprecedented insights into problems which had previously not been tractable with traditional analysis methods.

    BayesiaLab is the result of nearly twenty years of development by a team of researchers, led by Dr. Lionel Jouffe and Dr. Paul Munteanu, who are widely recognized as world leaders in their field of study. While cutting-edge research tools are often of no practical use outside the laboratory, BayesiaLab is a major exception. Its performance is like a Formula One race car; its everyday practicality resembles an SUV. As such, BayesiaLab provides an extremely user-friendly interface that allows novices and experts alike to easily and quickly navigate all the functions available in the program. Intuitive menu structures and step-by-step wizards allow end-users to focus on their principal analysis task without having to worry about idiosyncratic syntax or arcane commands.

  • Bayesia Engine

    The Bayesia Engine is an API that allows developers to integrate Bayesia’s technology in external applications and deploy models generated with BayesiaLab for automated inference, e.g. in real-time applications.

    You can access many of BayesiaLab’s functions outside the graphical user interface by using Bayesia’s Modeling and Inference Engines. You can thus leverage Bayesian networks in your own applications and deploy them for external access, e.g. by clients, without requiring them to install their own copy of BayesiaLab.

    The Bayesia Engine API is implemented as a pure Java class library (jar file), which can be easily integrated into any software project.

    With the Modeling Engine in the Bayesia Engine API you can create your own Bayesian networks from within your code and subsequently perform inference with the Inference Engine.

    The Inference Engine in the Bayesia Engine API allows you to perform inference on Bayesian networks from within your own application. Networks created with BayesiaLab, or with the Modeling Engine, can both be used for computing inference with the Inference Engine.

    A typical implementation scenario would be developing a Bayesian network offline with BayesiaLab and then deploying this network for real-time prediction on streaming data with the Inference Engine.

    For more details, please see the Bayesia Engine API Documentation.

  • BayesiaLab WebSimulator

    The BayesiaLab WebSimulator is a web-based application, hosted on Bayesia's servers in France, which allows you to share interactive models with your audience without having to install BayesiaLab on their computer. 

    The BayesiaLab Simulator uses your .xbl file to create a web page that is specific to your network. You can designate which nodes are accessible as Input Nodes and Output Nodes. Once the network is published, the BayesiaLab Simulator utilizes the Bayesia Engine API to perform inference in your network. This allows anyone to enter observations/evidence for the nodes in your network via the web. The BayesiaLab Simulator's web interface is responsive, thus allowing even tablet or smartphone users to work dynamically with your published network. Whenever evidence is set, the user will immediately see updated probability distributions of the Output Nodes.

    There are two kinds of simulators: the public simulators that are accessible to anybody, and the private simulators for which the access is restricted to the users that have the identifier of the model and its password.

    Five public simulators are automatically included with your BayesiaLab license.

    The private ones are available via different packages (5, 10, 20, 50 and 100 models/instances). 

    A model can only have one instance on the server, i.e. one concurrent access to the Bayesia Engine for inference. In order to add concurrent accesses, you need to add models.

  • BayesiaLab Courses

    Since 2009, we have been teaching Introductory and Advanced BayesiaLab courses all over the world. New York, Paris, London, Dubai, Singapore, and Sydney, just to name a few cities, are part of our regular teaching schedule.

    Beginning in 2019, we started offering Livestream options as well, so you can now participate in courses in real-time regardless of where they are hosted.

    And, just before the pandemic hit, we added on-demand self-study courses to our training portfolio, enabling you to start a full-featured BayesiaLab curriculum at any time.

    In the context of the 2020 BayesiaLab Conference in October 2020, we added VR-based courses, which opens up entirely new opportunities for learning.

  • BEKEE

    BayesiaLab Expert Knowledge Elicitation Environment, or BEKEE for short, is a web application that is designed to minimize detrimental group biases in brainstorming sessions for knowledge elicitation from domain experts. The central idea is not to coerce consensus, but rather to elicit everyone’s individual views regarding the domain under study. To ensure the independent elicitation of probabilities, BEKEE queries experts individually via web-based interactive or batch questionnaires, which is are linked to the BayesiaLab application of the session facilitator.

  • BCEM

    BayesiaLab Code Export Module, or BCEM for short, translates predictive network models into program code that can be pasted into other programs.

    BayesiaLab Professional is required to use this module.
