Effective Transfer Learning for Applied Conversational Understanding

Transfer learning has delivered an “ImageNet moment” for natural language processing (NLP). The explosion of new self-supervised language modeling approaches, coupled with ever increasing data size and compute power, has left the field with a wealth of opportunities to utilize transfer learning to achieve state of the art on a number of tasks. However, directly applying these approaches to real-world problems without a principled approach can often lead to mixed results both from a performance and an engineering standpoint. In this lecture, we will talk through case studies from NLP work at Twilio, and practical advice for making this approach work on real problems.

Luke de Oliveira is Technical Lead for AI and ML at Twilio, where he leads natural language understanding, storage, and runtime orchestration for the Twilio AI business unit. Previously, he was CEO & founder of Vai Technologies, which was acquired by Twilio in 2018. Luke completed his M.S. from Stanford ICME in 2016, and his B.S. in Applied Mathematics from Yale in 2014. He has published numerous academic articles in fields ranging from abstractive summarization to generative models for physics simulation. Luke is active in the startup community though roles as an advisor and investor.

Continuous approximation models for some modern logistical problems

In recent years, some of the most talked-about developments in the transportation sector include the use of drones, the introduction of last-mile delivery services, and the use of large-scale mapping data. Along with these new developments comes a host of new problems and trade-offs. We will discuss two such problems and use the "continuous approximation paradigm" to reveal basic insights about those factors that influence them most significantly.

Ramana Kompella, Head of Research, Emerging Tech and Incubation at Cisco

In the past few months, Cisco Research has started focusing on several emerging technology areas of interest to Cisco. In this talk, I will be talking a bit about  what these areas are of research interest are, how we are leveraging and engaging with universities for technology, societal, and business impact.

Dr. Ramana Kompella is currently the Head of Research in the Emerging Technology and Incubation group at Cisco. His previous experience includes co-founding successful startups, and providing engineering leadership to build world class products currently in use in several hundreds of customers’ data centers. Prior to his industry roles, he was a tenured faculty at Purdue in Computer Science Department, where he conducted research on systems and networking areas, with multi-million dollar grants from NSF and other industry sources. He co-advised several PhD and Masters students, and has co-authored 70+ publications in top networking and systems conferences such as SIGCOMM. He was the recipient of several awards including the prestigious NSF CAREER award.

Computational Methods in Ice Sheet Modeling for Next-Generation Climate Simulations

Recent observations show that both the Greenland and Antarctic ice sheets are losing mass at increasingly rapid rates [1]. In its fourth assessment report (AR4), the Intergovernmental Panel on Climate Change (IPCC) declined to include estimates of future sea-level change from dynamics of the polar ice sheets due to the inability of ice sheet models to mimic or explain observed dynamic behaviors, such as the acceleration and thinning then occurring on several of Greenland’s large outlet glaciers [2].

In recent years, there has been a push to develop “next generation” land-ice models and codes for integration into global Earth System Models (ESMs) to address this acknowledged limitation. This talk will give an overview of one such next-generation land-ice dynamical code (dycore) known as Albany Land-Ice (ALI) [3], currently under development at Sandia National Laboratories. Unlike many of its predecessors, ALI: (1) is able to perform realistic, high-resolution, continental scale simulations, (2) is robust, efficient and scalable on next-generation hybrid systems (multi-core, many-core, GPU, Intel Xeon Phi), (3) possesses built-in advanced analysis capabilities (e.g., sensitivity analysis, optimization, uncertainty quantification), and (4) is hooked up to the U.S. Department of Energy’s Energy Exascale Earth System Model (E3SM) as well as NCAR’s Community Earth System Model (CESM).

The ALI dycore is based on the so-called “First-Order Stokes” equations for the ice momentum balance [4], an attractive alternate to the more expensive “Full Stokes” model. Both the Full Stokes and the First-Order Stokes models assume that ice behaves like a very viscous, shear-thinning, non-Newtonian fluid, similar to lava flow. Following an overview of our land-ice model and project, I will describe some of the algorithms and software we have developed as a part of this project that have contributed to our dycore’s robustness and scalability. These include robust automatic-differentiation-based nonlinear solvers, scalable algebraic-multigrid-based iterative linear solvers [5], and stable semi-implicit First-Order Stokes-thickness coupling methods. I will also discuss some of the advanced analysis capabilities in ALI, namely a large-scale inversion approach we have developed for obtaining optimal ice initial conditions [6], our workflow towards quantifying uncertainties in land-ice models, and performance-portability of the ALI code to new and emerging architectures using the Kokkos library [7,9]. I will show results which demonstrate that the ALI dycore is scalable, fast and robust for production-scale land-ice problems on state-of-the-art HPC machines. I will also discuss results from a recent validation study in which ALI was used to simulate the Greenland ice sheet during the period 1991-2013 with realistic climate forcing, and the simulation data were compared with observational data collected by NASA satellites [8]. Finally, I will show some predictive dynamic experiments and simulations we are beginning to perform using ALI.

This work was done in collaboration with Luca Bertagna, Max Carlson, Irina Demeshko, Mike Eldred, Matt Hoffman, John Jakeman, Mauro Perego, Steve Price, Andy Salinger, Chad Sockwell, Ray Tuminaro and Jerry Watkins.

User Modeling: Putting AI to use for Personalization

AI has been applied for personalization for quite some time in the consumer domain for use cases such as movie recommendations on Netflix, and book and product recommendations on Amazon, and various other retailers. That personalization is primarily based on transaction data, which is structured in nature. The rise of social media data on platforms such as Twitter, Facebook, and Instagram, where users share/broadcast their daily activities and have social conversations with friends, is providing increased access to unstructured user data that can be analyzed (with users' permission) for personalization. This is enabling the development of next-generation User Models power by the latest advances in machine learning, wherein people’s personality traits, in-the-moment emotions, sentiment towards products, services, their communication tones, and intentions can be derived from this social media data. In this talk, I will discuss our work at IBM on building User Models that is being applied in various enterprise use cases including in the development of personalized Chatbots, personalized product & service recommendations. I’ll also discuss the genuine privacy concerns around using such user data and models and the new business models that are emerging, such as ‘bring-your-own-data, to address these concerns.
