Deep Learning for Climate Science

Deep Learning for Climate Science

Climate change is one of the most important problems facing humanity in the 21st century. Climate simulations provide us with a unique opportunity to understand the evolution of the climate system subject to various CO2 emission scenarios. Unfortunately, large scale climate simulations produce 100TB-sized spatio-temporal, multi-variate datasets, making it difficult to conduct sophisticated analytics. In this talk, I will present our results in applying Deep Learning for semi-supervised learning of extreme weather patterns. I will conclude with a summary of current applications of Deep Learning for a broad set of scientific use cases, and open research challenges for the future.

Prabhat leads the Data and Analytics Services team at NERSC. His current research interests applied statistics, machine learning, and high performance computing. He has worked on topics in scientific data management, parallel I/O, scientific visualization, computer graphics and computer vision in the past. Prabhat received an ScM in Computer Science from Brown University (2001) and a B.Tech in Computer Science and Engineering from IIT-Delhi (1999).

On the Path to Non-Biological Sentience

On the Path to Non-Biological Sentience

At Kindred our mission is to create human-like intelligence in machines, and our core hypothesis is that intelligence requires a body. We build robotic bodies of many different form factors and imbue them with new types of AI minds inspired by biological creatures’ brains. We pre-train these algorithms by demonstration, using large amounts of data from human operators, and craft reward functions such that the entities can subsequently become fully autonomous agents. Breakthroughs in robotics, increases in computational power, and advancements in machine learning algorithms are finally enabling us to train AI minds to have a more “general” form of intelligence. This presentation will describe our technology and address some of the questions that might arise as we begin to share our world with increasingly smarter robots.

Suzanne is co-founder and CSO of Kindred. She oversees the design and engineering of the company's human-like robots and is responsible for the development of cognitive architectures that allow these robots to learn about themselves and their environments. Before founding Kindred, Suzanne worked as a physicist at D-Wave, designing and building superconducting quantum processors, and as a researcher in quantum artificial intelligence software applications. Suzanne likes science outreach, retro tech art, coffee, cats, electronic music and extreme lifelogging. She is a published author of a book of art and poetry. She is passionate about robots and their role as a new form of symbiotic life in our society. Suzanne received her Ph.D. in experimental physics from the University of Birmingham (UK) in 2008, specializing in quantum device physics, microfabrication techniques, and low-temperature measurements of novel superconducting circuits.

Search Ranking And Personalization at Airbnb

Search Ranking And Personalization at Airbnb

Search ranking is a fundamental problem of crucial interest to major Internet companies, including web search engines, content publishing websites and marketplaces. However, despite sharing some common characteristics a one-size-fits-all solution does not exist in this space. Given a large difference in content that needs to be ranked and the parties affected by ranking, each search ranking problem is somewhat specific. Correspondingly, search ranking at Airbnb is quite unique, being a two-sided marketplace in which one needs to optimize for host and guest preferences, in a world where a user rarely consumes the same item twice and one listing can accept only one guest for a certain set of dates. In this talk, I will discuss challenges we have encountered and Machine Learning solutions we have developed for listing ranking at Airbnb. Specifically, the listing ranking problem boils down to prioritizing listings that are appealing to the guest but at the same time demoting listings tha t would likely reject the guest, which is not easily solvable using basic matrix completion or a straightforward linear model. I will shed the light on how we jointly optimize the two objectives by leveraging listing quality, location relevance, reviews, host response time as well as guest and host preferences and past booking history. Finally, we will talk about our recent work on using neural network models to train listing, query and user embeddings for purposes of enhancing search relevance and personalization, two core concepts in any modern search.

Mihajlo Grbovic, Ph.D. is a Senior Machine Learning Scientist on the Search Ranking Team at Airbnb. Prior to that, he was a Senior Research Manager at Yahoo Labs working on Advertising Sciences. He has more than 10 years of technical experience in applied Machine Learning, acting as a Science Lead in a portfolio of advertising technology projects on Monetization of Tumblr, Yahoo Email and Yahoo Search.

Music Discovery at Pandora

Finding the music of the moment can often be a challenging problem, even for humans with well-versed musical tastes. These challenges further explode into a myriad of complexities when attempting to construct algorithmic approaches for automatic playlist generation. A variety of factors play a role in influencing a listener’s perception of what music is appropriate on a given seed (e.g., musicological, social, geographical, generational), and these factors vary across different contexts and listeners. The talk will present an overview of recommendation at Pandora, followed by a deep dive into the challenges of recommending content in the long tail.

Erik Schmidt is a Senior Scientist at Pandora. Most recently, he led the development of Thumbprint Radio, a hyper-personalized product that has attracted over 20 million listeners to date. He has contributed numerous recommendation strategies to the Pandora ecosystem spanning playlists, station discovery, and concerts.

Beating Perils of Non-convexity: Guaranteed Training of Neural Networks using Tensor Methods

Neural networks have revolutionized performance across multiple domains such as computer vision and speech recognition. However, training a neural network is a highly non-convex problem and the conventional stochastic gradient descent can get stuck in spurious local optima. We propose a computationally efficient method for training neural networks that also has guaranteed risk bounds. It is based on tensor decomposition which is guaranteed to converge to the globally optimal solution under mild conditions. We explain how this framework can be leveraged to train feedforward and recurrent neural networks.

Her research interests include large-scale machine learning, high-dimensional statistics and probabilistic models. More recently, she has been working on inference and learning in latent variable models. She has received her Ph.D. from University of Southern California with a minor in Mathematics in 2015.

Who Said What: Modeling Individual Labelers Improves Classification

Who Said What: Modeling individual Labelers Improves Classification

Data are often labeled by many different experts, with each expert labeling a small fraction of the data and each sample receiving multiple labels. When experts disagree, the standard approaches are to treat the majority opinion as the truth or to model the truth as a distribution, but these do not make any use of potentially valuable information about which expert produced which label. We propose modeling the experts individually and then learning averaging weights for combining them, possibly in sample-specific ways. This allows us to give more weight to more reliable experts and take advantage of the unique strengths of individual experts at classifying certain types of data. We show that our approach performs better than three competing methods in computer-aided diagnosis of diabetic retinopathy.

Melody is deep learning resident at Google Brain. Previously she interned as a trader at D. E. Shaw and conducted stem cell research in Doug Melton's lab.

An Application of Gradient Boosted Decision Trees (GBDT) for Query Runtime Prediction

An Application of Gradient Boosted Decision Trees (GBDT) for Query Runtime Prediction

In 2016, Uber's went through an exponential growth. To support such an unprecedented growth in business, Uber had to rapidly scale out its infrastructure. The rapid growth in the core business and the number of products offered by Uber coupled with an increase in the number of data scientists and analysts meant an increasing load on our data systems. Specifically, having a stable and an efficient data warehouse was a fundamental requirement to sustain the pace at which Uber was growing and operating in the marketplace. The starting point of every data-driven decision at Uber typically begins with fetching data using our internal web-based tool called Querybuilder. More than 150K SQL queries are issued every week on our data warehouse through Querybuilder. To manage this load efficiently, it is very important to be able to accurately predict the runtime of the query before it hits the warehouse. In this study, we share our approach on how we used a Gradient Boosted Decision Tree model for predicting the runtime class of a query (short query or long query). Further, the predicted label was used to route the incoming query into an appropriate queue for execution in real-time. This approach of routing the queries based on the predictions from the classifier increased the overall efficiency of our warehouse. We observed a significant decrease in the average waiting for a query execution and increased the throughput of our system under peak load.

Abi Komma is a Senior Data Scientist in the Applied Machine Learning group at Uber. He focuses on applying regression, classification, and survival analysis techniques to build predictive models for various business problems at Uber. He holds a Master's degree in Transportation Engineering from University of Florida and a Bachelor’s degree in Civil Engineering from Indian Institute of Technology (IIT) Madras.

What Do Users Want? Using Semantics to Predict User Intents at Scale

Over the years search paradigm has shifted from document retrieval to deeper user intent understanding. Today’s users are no longer satisfied with seeing a list of relevant documents, instead they want to complete tasks and take actions on them. The question I will address in this talk is how to build an automated user intent understanding system, where given a query like "Mia" the user sees relevant and personalized recommendations such as "buy latest album of the singer”, or "check-in flight to Miami". I will begin by introducing the task and the main challenges with semantic understanding. Then, I will describe categorization and structured prediction algorithms for entity detection and intent prediction. Finally, I will highlight results and findings for user intent prediction from shopping, movies, restaurant and sport domains.

Control of Memory, Active Perception, and Action in 3D world

In this work, we introduce a set of reinforcement learning tasks in Minecraft. We use these tasks to systematically compare existing deep reinforcement learning (DRL) architectures with our new memory-based architectures. These tasks are designed to emphasize issues that pose challenges including partial observability, delayed rewards, high-dimensional visual observations, and the need to use active perception so as to perform well in the tasks. We evaluate the generalization performance of the architectures on environments not used during training. The experimental results show that our new architectures generalize to unseen environments better than existing DRL architectures.

Junhyuk is a 2rd-year PhD student in Computer Science and Engineering at University of Michigan. He is working on the intersection between deep learning and reinforcement learning under the supervision of Professor Honglak Lee and Professor Satinder Singh.

End-to-end Machine Intelligence

The common perception of machine learning is that it starts with data and ends with a model. In real-world production systems, the traditional data science and machine learning workflow of data preparation, feature engineering and model selection, while important, is only one aspect. True machine intelligence requires continuous, real-time learning by closing the feedback loop. Equally important for enterprise-grade and mission-critical systems are the typical elements of software systems, such as scalability, fault tolerance and security.

Nick is a Principal Engineer at IBM’s Spark Technology Center. He is a member of the Apache Spark PMC and author of Machine Learning with Spark. Previously, he co-founded Graphflow, a startup focused on recommendations and customer intelligence. He has worked at Goldman Sachs, Cognitive Match, and led the Data Science team at Mxit, Africa’s largest social network.
