Uncertainty Quantification in Neural Networks with Keras
If we train a dog/cat classifier, and test it on a human image, what can be a right answer? How can our model let us know that it cannot produce an answer? In this talk we will cover methods that extend machine learning models to estimate their uncertainty, like Bayesian Neural Networks, and how they can be implemented in python using Keras and other frameworks.
Dr. Matias Valdenegro (male) is a researcher at Interactive Machine Learning Team of the Robotics Innovation Center, German Research Center for Artificial Intelligence. He received his PhD in Electrical Engineering from Heriot-Watt University (Edinburgh, Scotland) in 2019, a M.Sc in Autonomous Systems from the Bonn-Rhein-Sieg University of Applied Sciences (Sankt Augustin, Germany) in 2014, and his Computer Engineering degree from Universidad Tecnologica Metropolitana (Santiago, Chile) in 2009.
His PhD research is on the problem of detecting Marine Debris on Forward-Looking Sonar images using Neural Networks. His research interests include Robot Perception, Reinforcement Learning, Uncertainty in Machine Learning, and their applications to Robotics.
