Read MoreBayes Server™ not only supports prediction based on complex and hidden relationships in data, but also allows reasoning from outputs to inputs, diagnostics, anomaly detection & time series.
Read MoreBayes Server™ models can include costs and decisions, that make decision making possible when uncertainty is present (Decision Automation, Decision Graphs or Evidence optimization).
Read MoreIn addition to an advanced User Interface, Bayes Server can be driven programmatically via a number of advanced APIs, that include all the features of the User Interface and more.
Reduce uncertainty when operating in complex environments with unknown or incomplete information, by the repeated use of AI guided questioning/sensing and updating beliefs based on responses. Build agents using data and/or experts that can then adapt when deployed.
Build solutions to troubleshoot and diagnose complex problems, such as aero-engines, gearboxes & patients.
Make rational cost based decisions in complex uncertain environments, such as those where communication is delayed or cut-off, or when AI can outperform humans in terms of accuracy/speed/cost.
Use advanced anomaly detection techniques to monitor complex data, such as sensor data or market data, to detect anomalous behavior and provide early warning of failure or other potentially catastrophic or costly events.
Move beyond Fault Trees, Event Trees, Bow-Tie models & FMECA toward sophisticated risk analysis approaches with Bayes Server.
Identify groups and relationships in data that were previously unknown.
