Abstract Summary:

Large-scale Machine Learning: Deep, Distributed and Multi-Dimensional:
Modern machine learning involves deep neural network architectures which yields state-of-art performance on multiple domains such as computer vision, natural language processing and speech recognition. As the data and models scale, it becomes necessary to have multiple processing units for both training and inference. Apache MXNet is an open-source framework developed for distributed deep learning. I will describe the underlying lightweight hierarchical parameter server architecture that results in high efficiency in distributed settings.
Pushing the current boundaries of deep learning requires using multiple dimensions and modalities. These can be encoded into tensors, which are natural extensions of matrices. We present new deep learning architectures that preserve the multi-dimensional information in data end-to-end. We show that tensor contractions and regression layers are an effective replacement for fully connected layers in deep learning architectures. They result in significant space savings with negligible performance degradation. These functionalities are available in the Tensorly package with MXNet backend interface for large-scale efficient learning.

Jonas Schneider, Head of Robotics, OpenAI

Jonas leads technology development for OpenAI’s robotics group, developing methods to apply machine learning and AI to robots. He also helped build the infrastructure to scale OpenAI’s distributed ML systems to thousands of machines.

Abstract Summary:

Machine Learning Systems at Scale:
OpenAI is a non-profit research company, discovering and enacting the path to safe artificial general intelligence. As part of our work, we regularly push the limits of scalability in cutting-edge ML algorithms. We’ve found that in many cases, designing the systems we build around the core algorithms is as important as designing the algorithms themselves. This means that many systems engineering areas, such as distributed computing, networking, and orchestration, are crucial for machine learning to succeed on large problems requiring thousands of computers. As a result, at OpenAI engineers and researchers work closely together to build these large systems as opposed to a strict researcher/engineer split. In this talk, we will go over some of the lessons we’ve learned, and how they come together in the design and internals of our system for learning-based robotics research.

Doug Eck, Research Scientist, Google

Doug leads Magenta, a Google Brain project working to generate music, video, image and text using deep learning and reinforcement learning.

Before Magenta, Doug led the Google Play Music search and recommendation team. From 2003 to 2010 Doug was faculty at the University of Montreal’s MILA Machine Learning lab, where he worked on expressive music performance and automatic tagging of music audio.

Abstract Summary:

The Role of AI and Machine Learning in Creativity:
I’ll discuss Magenta, a Google Brain project investigating music and art generation using deep learning and reinforcement learning. I’ll describe the goals of Magenta and how it fits into the general trend of AI moving into our daily lives. One crucial question is: Where does AI and Machine Learning fit in the creative process? I’ll argue that it’s about augmenting and extending the artist rather than just creating artifacts (songs, paintings, etc.) with machines. I’ll talk about two recent projects. In the first, we explore the use of recurrent neural networks to extend musical phrases in different ways. In the second we look at teaching a neural network to draw with strokes. This will be a high-level overview talk with no need for knowledge of AI or Machine Learning.

Abstract Summary:

Tensor Decomposition: A Mathematical Tool for Data Analysis:
Tensors are multiway arrays, and tensor decompositions are powerful tools for data analysis. In this talk, we demonstrate the wide-ranging utility of the canonical polyadic (CP) tensor decomposition with examples in neuroscience and chemical detection. The CP model is extremely useful for interpretation, as we show with an example in neuroscience. However, it can be difficult to fit to real data for a variety of reasons. We present a novel randomized method for fitting the CP decomposition to dense data that is more scalable and robust than the standard techniques. We further consider the modeling assumptions for fitting tensor decompositions to data and explain alternative strategies for different statistical scenarios, resulting in a _generalized_ CP tensor decomposition.

Abstract Summary:

ML to Cure the World:
The practice of medicine involves diagnosis, treatment, and prevention of diseases. Recent technological breakthroughs have made little dent to the centuries-old system of practicing medicine: complex diagnostic decisions are still mostly dependent on “educated” work-ups of the doctors, and rely on somewhat outdated tools and incomplete data. All of this often leads to imperfect, biased, and, at times, incorrect diagnosis and treatment.

With a growing research community as well as tech companies working on AI advances to medicine, the hope for healthcare renaissance is definitely not lost. The emphasis of this talk will be on ML-driven medicine. We will discuss recent AI advancements for aiding medical decision including language understanding, medical knowledge base construction and diagnosis systems. We will discuss the importance of personalized medicine that takes into account not only the user, but also the context, and other metadata. We will also highlight challenges in designing ML-based medical systems that are accurate, but at the same time engaging and trustworthy for the user.

Abstract Summary:

Deep Reinforcement Learning with Shallow Trees:
In this talk, I present Concept Network Reinforcement Learning (CNRL), developed at Bonsai. It is an industrially applicable approach to solving complex tasks using reinforcement learning, which facilitates problem decomposition, allows component reuse, and simplifies reward functions. Inspired by Sutton’s options framework, we introduce the notion of “Concept Networks” which are tree-like structures in which leaves are “sub-concepts” (sub-tasks), representing policies on a subset of state space. The parent (non-leaf) nodes are “Selectors”, containing policies on which sub-concept to choose from the child nodes, at each time during an episode. There will be a high-level overview on the reinforcement learning fundamentals at the beginning of the talk.

Abstract Summary:

Uncertainty Estimation in Neural Networks for Time Series Prediction at Uber:
Reliable uncertainty estimations for forecasts are critical in many fields, including finance, manufacturing, and meteorology.

At Uber, probabilistic time series forecasting is essential for accurate hardware capacity predictions, marketing spend allocations, and real-time system outage detection across millions of metrics. Classical time series models are often used in conjunction with a probabilistic formulation for uncertainty estimation. However, such models can be hard to tune, scale, and add exogenous variables to. Motivated by the recent resurgence of Long Short Term Memory networks, we propose a novel end-to-end Bayesian deep model that provides time series prediction along with uncertainty estimation at scale.

Abstract Summary:

Counter Intuitive Machine Learning for the Industrial Internet of Things:
The Industrial Internet of Things (IIoT) is the infrastructure and data flow built around the world’s most valuable things like airplane engines, medical scanners, nuclear power plants, and oil pipelines. These machines and systems require far greater uptime, security, governance, and regulation than the IoT landscape based around consumer activity. In the IIoT the cost of being wrong can be the catastrophic loss of life on a massive scale. Nevertheless, given the growing scale through the digitalization of industrial assets, there is clearly a growing role for machine learning to help augment and automate human decision making. It is against this backdrop that traditional machine learning techniques must be adapted and need based innovations created. We see industrial machine learning as distinct from consumer machine learning and in this talk we will cover the counterintuitive changes of featurization, metrics for model performance, and human-in-the-loop design changes for using machine learning in an industrial environment.

Abstract Summary:

Getting Value Out of Chat Data:
Chat-based interfaces are increasingly common, whether as customers interacting with companies or as employees communicating with each other within an organization. Given the large number of chat logs being captured, along with recent advances in natural language processing, there is a desire to leverage this data for both insight generation and machine learning applications. Unfortunately, chat data is user-generated data, meaning it is often noisy and difficult to normalize. It is also mostly short texts and heavily context-dependent, which cause difficulty in applying methods such as topic modeling and information extraction.

Despite these challenges, it is still possible to extract useful information from these data sources. In this talk, I will be providing an overview of techniques and practices for working with chat-based user interaction data with a focus on machine-augmented data annotation and unsupervised learning methods.

Abstract Summary:

Deriving Actionable Insights from High Volume Media Streams:
Media analysts have to deal with with analyzing high volumes of real-time news feeds and social media streams which is often a tedious process because they need to write search profiles for entities. Python tools like NLTK do not scale to large production data sets and cannot be plugged into a distributed scalable frameworks like Apache Flink.

Apache Flink being a streaming first engine is ideally suited for ingesting multiple streams of news feeds, social media, blogs etc.. and for being able to do streaming analytics on the various feeds. Natural Language Processing tools like Apache OpenNLP can be plugged into Flink streaming pipelines so as to be able to perform common NLP tasks like Named Entity Recognition (NER), Chunking, and text classification.

In this talk, we’ll be building a real-time media analyzer which does Named Entity Recognition (NER) on the individual incoming streams, calculates the co-occurrences of the named entities and aggregates them across multiple streams; index the results into a search engine and being able to query the results for actionable insights. We’ll also be showing as to how to handle multilingual documents for calculating co-occurrences.

NLP practitioners will come away from this talk with a better understanding of how the various Apache OpenNLP components can help in processing large streams of data feeds and can easily be plugged into a highly scalable and distributed framework like Apache Flink.
