Applicability

Smart System

Learns with HISTORICAL TRENDS

Live data becomes historical over time

What do we want to build?

Trading Data

“According to historical trends, there’s an 80% chance this stock prices might go down within the next few minutes"

"How were the technical indicator readings when the latest price drops happened? "

Live Data

Data Temperature

Hot

Cold

Apache Hawq

Apache Geode / GemFire1- Live data is ingested into the grid

3 - Results are pushed immediately to deployed applications

4 - “Hot" data ages, becoming part of the historical dataset

5 - Re-training triggered, ML model updated.

Spring XD

2 - Trained ML model compares new data to historical patterns

The Machine Learning Pipeline data flow
