How to Stack Neural Networks together ? Ideas and Applications
06-17, 15:30–17:00 (Europe/London), Tower Suite 1

Exploring the process, implementation, practical applications, and advantages of stacking neural networks together. The tutorial focuses on building tunable, high-performance, multi-data-type feature models seamlessly using network concatenations in TensorFlow. We implement 3 examples and also derive explainability for a stacked neural network.


Stacking different Neural Nets together is extremely beneficial for applications that involve the availability of different data types ( Images + Text + Tabular ) to make better decisions. In this tutorial, we will find answers to fundamental questions behind stacking: Why stack? How to stack? Train - individually / together? Number of models? Hyperparameter tuning? Stacking pre-trained models? Accessing models post stacked training and very importantly, explainability? and consequently, implement Stacking for 3 use cases - Multi Data Type, Pretrained Model, Restricted Neural Nets.
