Johannes Schmidt-Hieber - Mathematics for Deep Neural Networks: Energy landscape and open problems (Lecture 5/5)

To derive a theory for gradient descent methods, it is important to have some understanding of the energy landscape. In this lecture, an overview of existing results is given. The second part of the…

Johannes Schmidt-Hieber - Mathematics for Deep Neural Networks: Statistical theory for deep ReLU networks (Lecture 4/5)

We outline the theory underlying the recent bounds on the estimation risk of deep ReLU networks. In the lecture, we discuss specific properties of the ReLU activation function that relate to skipping…

Cherie R. Kagan - Designer Colloidal Nanocrystal Materials for Electronic and Optical Applications

Semiconductor and plasmonic nanocrystals are known for their size and shape dependent photo-luminescence and localized surface plasmon resonances, respectively. In this talk, I will describe the use…

Johannes Schmidt-Hieber - Mathematics for Deep Neural Networks: Advantages of Additional Layers (Lecture 3/5)

Why are deep networks better than shallow networks? We provide a survey of the existing ideas in the literature. In particular, we discuss localization of deep networks, functions that can be easily…

Michael Lemonick - How a Failed Astrophysics Major Became a Successful Science Writer

I knew from the time I was a very young child that I wanted to be an astronomer. The dream lasted until I got to college, where I learned to my dismay that I actually had no passion for doing what an…

Johannes Schmidt-Hieber - Mathematics for Deep Neural Networks : Theory for shallow networks (Lecture 2/5)

We start with the universal approximation theorem and discuss several proof strategies that provide some insights into functions that can be easily approximated by shallow networks. Based on this, a…

Zeb Rocklin - The Science of Origami

What kinds of shapes can you make by folding a sheet of paper? How strong can you make them, or how flexible? Although we've been folding paper for centuries, we're still discovering…

Galyna Livshyts - A Tight Net with Respect to a Random Matrix Norm and Applications to Estimating Singular Values

In this talk we construct a net around the unit sphere with good properties. We show that with exponentially high probability, the value of |Ax| on the sphere can be approximated well using this net,…

How the Universe Made the Elements in the Periodic Table - James Sowell

The creation of the elements in the universe took billions of years and required various processes.The first few minutes of the big bang produced only hydrogen (H) and helium (He). No new elements…
