Class FaceNetHelper

java.lang.Object

org.deeplearning4j.zoo.model.helper.FaceNetHelper

public class FaceNetHelper
extends Object

Inception is based on GoogleLeNet configuration of convolutional layers for optimization of resources and learning. You can use this module to add Inception to your own custom models.
The GoogleLeNet paper: https://arxiv.org/abs/1409.4842

This module is based on the Inception GraphBuilderModule built for Torch and a Scala implementation of GoogleLeNet.
