What is Predictive Analytics?

“Technology that LEARNS from EXPERIENCE (data) to PREDICT the future”

It uses techniques from the following:Statistics Machine LearningData MiningGame theory

What Is Predixion Insight?

Some Customer Scenarios

92%

Healthcare: Preventable Hospital Readmissions

• Hospital data is used to build a hospital-specific Predixion model • The Predixion model is then used to risk stratify patients upon admission • Risk scores are updated throughout the patient’s stay • Readmission risk scores are used by care givers to target appropriate

patient care paths.

Oil and Gas: High Velocity Streaming Predictions

Predixion model pushed into CEP (complex event processing)/StreamThousands of predictions scored per second in memory, near zero latencyContinuous processing of event streams from multiple sourcesGathers and preprocesses data into predictors for predictive modelsReports in real time on potential failures for preventative maintenance

Streaming Sensor data
