Introduction

The Simple Tensorflow AI Decision plugin allows one to map it on a process route, execute a pre-trained Tensorflow AI model and use the output result for decision making.

The following are the list of required items before using Simple Tensorflow AI Decision:

  • an exported frozen model of Tensorflow AI model file in .pb format
  • the list of Input Names and each of their Data Type
  • the list of Output Names and each of their Data Type
  • Dictionary file in .csv format (if any)
Please take note that the Decision Tool Plugin will take precedence over existing conventional conditional setup in the Process Builder
New Feature

This is a new feature in Joget DX
