Neural-network models have a set of configuration hyperparameters tuned to optimize a given model’s accuracy. While accurate models are the primary goal in machine learning, it is often necessary to reduce training time to avoid outdated models and maintain computational feasibility.

Yahav Shadmi demonstrates how to select hyperparameters to significantly reduce training time while maintaining accuracy, present examples for popular neural network models used for text and images, and describe a real-world optimization method for tuning.

This presentation is coauthored by Amitai Armon.
