Uncertainty Quantification in Machine Learning | Lalitha Venkataramanan, Schlumberger

1:30pm to 2:30pm

Location: 

Harvard University, Maxwell Dworkin G115, 33 Oxford Street, Cambridge MA

IACS seminars are free and open to the public; no registration required. Lunch will not be provided.

ABSTRACT: Deep learning techniques have been shown to be extremely effective for various classification and regression problems, but quantifying the uncertainty of their predictions and separating them into the epistemic and aleatoric fractions is still considered challenging. In subsurface characterization projects, tools consisting of seismic, sonic, magnetic resonance, resistivity, dielectric and/or nuclear sensors are sent downhole through...

Hardware and Software Co-design: Preparing and Optimizing Scientific Applications for Exascale Computing | Nicholas Malaya, Advanced Micro Devices

1:30pm to 2:30pm

Location: 

Harvard University, Maxwell Dworkin G115, 33 Oxford Street, Cambridge MA

IACS seminars are free and open to the public; no registration is required.  Lunch will not be provided.

ABSTRACT: The largest computers in the world are an essential tool for key scientific simulations, spanning a wide range of applications across fundamental science, in areas such as cosmology or turbulent flows, and applied engineering, such as material science and storm surge modeling. Historically, Moore's law has driven rapid expansion of computational capability, with the largest computers following an exponential growth in FLOPs....

What Do Models of Natural Language "Understanding" Actually Understand? | Ellie Pavlick, Brown University

1:30pm to 2:30pm

Location: 

Harvard University, Maxwell Dworkin G115, 33 Oxford Street, Cambridge MA

IACS seminars are free and open to the public; no registration is required. Lunch will not be provided.

ABSTRACT: Natural language processing has become indisputably good over the past few years. We can perform retrieval and question answering with purported super-human accuracy, and can generate full documents of text that seem good enough to pass the Turing test. In light of these successes, it is tempting to attribute the empirical performance to a deeper "understanding" of language that the models have acquired. Measuring natural language...

Physics-Informed Machine Learning in Astronomy | Josh Bloom, Berkeley

1:30pm to 2:30pm

Location: 

Harvard University, Maxwell Dworkin G115, 33 Oxford Street, Cambridge MA

IACS seminars are free and open to the public; no registration required.  Lunch will not be provided.

ABSTRACT: While “off-the-shelf” ML has become pervasively used throughout astronomy inference workflows, there is an exciting new space emerging where novel learning algorithms and computational approaches are demanded and developed to address specific domain questions. After describing such efforts—in the search for Planet 9 and new classes of variable sources—Dr. Bloom will turn his attention to new practical implementations and uses...

Can Computers Create Art? | Aaron Hertzmann, Principal Scientist at Adobe, Inc.

1:30pm to 2:30pm

Location: 

Harvard University, Maxwell Dworkin G115, 33 Oxford Street, Cambridge MA

IACS Seminars are free and open to the public; no registration required.  Lunch will not be provided.

Abstract: In this talk, Dr. Hertzmann will discuss whether computers, using Artificial Intelligence (AI), can create art. His talk will cover the history of automation in art, examining the hype and reality of AI tools for art together with predictions about how they will be used. Dr. Hertzmann will also discuss different scenarios for how an algorithm could be considered the author of a piece of artwork, which,...
