From The President Bienvenido,

The 2016 NIPS Conference and Workshops in Barcelona will host a record number of participants, topping the record number last year in Montréal by over 1800! Barcelona Montreal Montreal Lake Tahoe Lake Tahoe Granada Vancouver

Year Registrations 2016 5680 2015 3800 2014 2478 2013 1902 2012 1610 2011 1394 2010 1301

We had to cap the registration for the first time because of limited space in the Convention Center. Since 2013 the number of registered participants has been growing exponentially and we have outgrown the venues that were planned several years ago. The likelihood of a cap was announced in September when registration opened, but many who in the past registered late were caught by surprise. We apologize to all who we had to turn away. Register early and register often.

The NIPS Workshops attract as many attendees as the NIPS Conference and this year there will be 50 sessions covering a broad range of topics. Despite its rapid growth, NIPS has maintained the highest standards and this year our acceptance rate was 24%. The technical program includes 7 invited talks and 569 accepted papers, selected from a total of 2403 submissions considered by the program committee. Papers presented at the conference will appear in “Advances in Neural Information Processing 29,” edited by Ulrike von Luxburg, Isabelle Guyon, Daniel D. Lee, Masashi Sugiyama and Roman Garnett. In 2017, NIPS will be in Long Beach, California – warmer weather! NIPS will return to Montréal, Canada, in 2018.

For the first time the main NIPS Conference will have two tracks. Researchers from many fields come to NIPS and our goal is to provide a common meeting ground for all. Unlike most large conferences that are multitrack, NIPS has maintained a single track to keep the meeting from fragmenting. Along with more participants NIPS has had more submissions and with two tracks we were able to expand the number of oral talks and still have time for breaks.

Long Beach, California 2017, Dec 4 - 9

The Posner Lecture this year will be given by Yann LeCun and the Breiman Lecture by Susan Holmes. Ed Posner founded NIPS in 1987 and Leo Breiman bridged the statics and machine learning communities. The Symposium track between the end of the conference and the beginning of the workshops was popular last year in Montreal and this year three exciting symposia are on our program. 8

Monday Tutorial Session - 8:30 - 10:30 AM Variational Inference: Foundations and Modern Methods Area 1 + 2

David Blei (Columbia Univ.) Shakir Mohamed (DeepMind) Rajesh Ranganath (Princeton Univ.) One of the core problems of modern statistics and machine learning is to approximate difficult-to-compute probability distributions. This problem is especially important in probabilistic modeling, which frames all inference about unknown quantities as a calculation about a conditional distribution. In this tutorial we review and discuss variational inference (VI), a method a that approximates probability distributions through optimization. VI has been used in myriad applications in machine learning and tends to be faster than more traditional methods, such as Markov chain Monte Carlo sampling. Brought into machine learning in the 1990s, recent advances and easier implementation have renewed interest and application of this class of methods. This tutorial aims to provide both an introduction to VI with a modern view of the field, and an overview of the role that probabilistic inference plays in many of the central areas of machine learning.

Crowdsourcing: Beyond Label Generation Area 3

Jennifer Wortman Vaughan (Microsoft Research) This tutorial will showcase some of the most innovative uses of crowdsourcing that have emerged in the past few years. While some have clear and immediate benefits to machine learning, we will also discuss examples in which crowdsourcing has allowed researchers to answer exciting questions in psychology, economics, and other fields. We will discuss best practices for crowdsourcing (such as how and why to maintain a positive relationship with crowdworkers) and available crowdsourcing tools. We will survey recent research examining the effect of incentives on crowdworker performance. Time permitting, we will also touch on recent ethnographic research studying the community of crowdworkers and/or delve into the ethical implications of crowdsourcing.

Deep Reinforcement Learning Through Policy Optimization Rooms 211 + 212

Pieter Abbeel (UC Berkley) John Schulman (Open AI) Deep Reinforcement Learning (Deep RL) has seen several breakthroughs in recent years. In this tutorial we will focus on recent advances in Deep RL through policy gradient methods and actor critic methods. These methods have shown significant success in a wide range of domains, including continuous-action domains such as manipulation, locomotion, and flight. They have also achieved the state of the art in discrete action domains such as Atari. Fundamentally, there are two types of gradient calculations: likelihood ratio gradients (aka score function gradients) and path derivative gradients (aka perturbation analysis gradients). We will teach policy gradient methods of each type, connect with Actor-Critic methods (which learn both a value function and a policy), and cover a generalized view of the

The tutorial has three parts. First, we provide a broad review of variational inference from several perspectives. This part serves as an introduction (or review) of its central concepts. Second, we develop and connect some of the pivotal tools for VI that have been developed in the last few years, tools like Monte Carlo gradient estimation, black box variational inference, stochastic approximation, and variational auto-encoders. These methods have lead to a resurgence of research and applications of VI. Finally, we discuss some of the unsolved problems in VI and point to promising research directions. Learning objectives: • Gain a well-grounded understanding of modern advances in variational inference • Understand how to implement basic versions for a wide class of models • Understand connections and different names used in other related research areas • Understand important problems in variational inference research Target audience: • Machine learning researchers across all level of experience from first year grad students to other more experienced researchers • Targeted at those who want to understand recent advances in variational inference • Basic understanding of probability is sufficient

Despite the inclusion of best practices and tools, this tutorial should not be viewed as a prescriptive guide for applying existing techniques. The goals of the tutorial are to inspire you to find novel ways of using crowdsourcing in your own research and to provide you with the resources you need to avoid common pitfalls when you do. Target audience: This tutorial is open to anyone who wants to learn more about cutting edge research in crowdsourcing. No assumptions will be made about the audience’s familiarity with either crowdsourcing or specific machine learning techniques. Anyone who is curious is welcome to attend! As the tutorial approaches, more information will be available on the tutorial website:

computation of gradients of expectations through Stochastic Computation Graphs. Learning Objectives: The objective is to provide attendees with a good understanding of foundations as well as recent advances in policy gradient methods and actor critic methods. Approaches that will be taught: Likelihood Ratio Policy Gradient (REINFORCE), Natural Policy Gradient, Trust Region Policy Optimization, Generalized Advantage Estimation, Asynchronous Advantage Actor Critic, Path Derivative Policy Gradients, Deterministic Policy Gradient, Stochastic Value Gradients, Guided Policy Search. As well as a generalized view of the computation of gradients of expectations through Stochastic Computation Graphs. Target Audience: Machine learning researchers. RL background not assumed, but some prior familiarity with the basic concepts could be helpful. Good resource: Sutton and Barto Chapters 3 & 4 (http://webdocs. 13

Monday Tutorial Session - 11 AM - 1 PM Nuts and Bolts of Building AI systems using Deep Learning Area 1 & 2

Andrew Y Ng (Stanford University) How do you get deep learning to work in your business, product, or scientific study? The rise of highly scalable deep learning techniques is changing how you can best approach AI problems. This includes how you define your train/dev/test split, how you organize your data, how you should think through your search among promising model architectures, and even how you might develop new AI-enabled products. In this tutorial, you’ll learn about the emerging best practices in this nascent area. You’ll come away able to better organize your and your team’s work when developing deep learning applications.

Natural Language Processing for Computational Social Science Area 3

Cristian Danescu-Niculescu-Mizil (Cornell University) Lillian J Lee (Cornell University) More and more of life is now manifested online, and many of the digital traces that are left by human activity are increasingly recorded in natural-language format. This tutorial will examine the opportunities for natural language processing (NLP) to contribute to computational social science, facilitating our understanding of how humans interact with others at both grand and intimate scales.

Theory and Algorithms for Forecasting NonStationary Time Series Rooms 211 + 212

Vitaly Kuznetsov (Google) Mehryar Mohri (Courant Institute, Google) Time series appear in a variety of key real-world applications such as signal processing, including audio and video processing; the analysis of natural phenomena such as local weather, global temperature, and earthquakes; the study of economic variables such as stock values, sales amounts, energy demand; and many other areas. But, while time series forecasting is critical for many applications, it has received little attention in the ML community in recent years, probably due to a lack of familiarity with time series and the fact that standard i.i.d. learning concepts and tools are not readily applicable in that scenario. This tutorial precisely addresses these and many other related questions. It provides theoretical and algorithmic tools for research related to time series and for designing new solutions. We first


Learning objectives: • Understand best-practices for applying deep learning in your organization, whether improving existing applications or creating brand new ones. • Be able to organize and help prioritize your team’s work using principles suited to the deep learning era; understand how these practices have changed relative to previous machine learning eras. • Able to apply error analysis and other debugging techniques suited to deep learning systems. • Gain a systematic process for selecting among architectures and data for your machine learning tasks. Target audience: Attendees should have basic knowledge of machine learning (such as supervised learning). Prior knowledge in deep learning is helpful but not required.

Learning objectives: • Influence and persuasion: Can language choices affect whether a political ad is successful, a social-media post gets more re-shares, or a get-out-the-vote campaign will work? • Language as a reflection of social processes: can we detect status differences, or more broadly, the roles people take in online communities? How does language define collective identity, or signal imminent departure from a community? • Group success: can language cues help us predict whether a group will cohere or fracture? Or whether a betrayal is forthcoming? Or whether a team will succeed at its task? • Understand important problems in variational inference research Target audience: Unrestricted

present a concise introduction to time series, including basic concepts, common challenges and standard models. Next, we discuss important statistical learning tools and results developed in recent years and show how they are useful for deriving guarantees and designing algorithms both in stationary and non-stationary scenarios. Finally, we show how the online learning framework can be leveraged to derive algorithms that tackle important and notoriously difficult problems including model selection and ensemble methods. Learning objectives: • familiarization with basic time series concepts • introduction to statistical learning theory and algorithms for stationary and non-stationary time series • introduction to model selection and ensemble methods for time series via online learning Target audience: This tutorial is targeted for a very general ML audience and should be accessible to most machine learning researchers and practitioners. We will introduce all the necessary tools from scratch and of course make slides and other detailed tutorial documents available.

Monday Tutorial Session - 2:30 - 4:30 PM Session Chair: Tamara Broderick

Generative Adversarial Networks Area 1 & 2

Ian Goodfellow (OpenAI) Generative adversarial networks (GANs) are a recently introduced class of generative models, designed to produce realistic samples. This tutorial is intended to be accessible to an audience who has no experience with GANs, and should prepare the audience to make original research contributions applying GANs or improving the core GAN algorithms. GANs are universal approximators of probability distributions. Such models generally have an intractable loglikelihood gradient, and require approximations such as Markov chain Monte Carlo or variational lower bounds to make learning feasible. GANs avoid using either of these classes of approximations. The learning process consists of a game between two adversaries: a generator network that attempts to produce realistic samples, and a discriminator network that attempts to identify whether samples originated from the training data or from the generative model. At the Nash equilibrium of this game, the generator network reproduces the data distribution exactly, and the discriminator network cannot distinguish samples from the model from training data. Both networks can be trained using stochastic gradient descent with exact gradients computed by maximum likelihood.

Topics include: - An introduction to the basics of GANs. - A review of work applying GANs to large image generation. - Extending the GAN framework to approximate maximum likelihood, rather than minimizing the Jensen-Shannon divergence. - Improved model architectures that yield better learning in GANs. - Semi-supervised learning with GANs. - Research frontiers, including guaranteeing convergence of the GAN game. - Other applications of adversarial learning, such as domain adaptation and privacy. Learning objectives: • To explain the fundamentals of how GANs work to someone who has not heard of them previously • To bring the audience up to date on image generation applications of GANs • To prepare the audience to make original contributions to generative modeling research Target audience: People who are interested in generative modeling. Both people who do not have prior knowledge of GANs and people who do should find something worthwhile, but the first part of the tutorial will be less interesting to people who have prior knowledge of GANs

Large-Scale Optimization: Beyond Stochastic Gradient Descent and Convexity Rooms 211 + 212

Suvrit Sra (MIT) Francis Bach (INRIA) Stochastic optimization lies at the heart of machine learning, and its cornerstone is stochastic gradient descent (SGD), a staple introduced over 60 years ago! Recent years have, however, brought an exciting new development: variance reduction (VR) for stochastic methods. These VR methods excel in settings where more than one pass through the training data is allowed, achieving convergence faster than SGD, in theory as well as practice. These speedups underline the huge surge of interest in VR methods; by now a large body of work has emerged, while new results appear regularly! This tutorial brings to the wider machine learning audience the key principles behind VR methods, by positioning them vis-à-vis SGD. Moreover, the tutorial takes a step beyond convexity and covers research-edge

Target audience: The majority of this tutorial will be targeted at an audience with basic machine learning knowledge. No background in medicine or health care is needed. We will make our slides and any relevant documents accessible after the talk.

results for non-convex problems too, while outlining key points and as yet open challenges. Learning objectives: Introduce fast stochastic methods to the wider ML audience to go beyond a 60-year-old algorithm (SGD) – Provide a guiding light through this fast moving area, to unify, and simplify its presentation, outline common pitfalls, and to demystify its capabilities – Raise awareness about open challenges in the area, and thereby spur future research. Target audience: • Graduate students (masters as well as PhD stream) • ML researchers in academia and industry who are not experts in stochastic optimization • Practitioners who want to widen their repertoire of tools


Posner Lecture - Monday @ 5:30pm Predictive Learning Area 1 & 2

Yann LeCun (Facebook, New York University) Deep learning has been at the root of significant progress in many application areas, such as computer perception and natural language processing. But almost all of these systems currently use supervised learning with human-curated labels. The challenge of the next several years is to let machines learn from raw, unlabeled data, such as images, videos and text. Intelligent systems today do not possess “common sense”, which humans and animals acquire by observing the world, acting in it, and understanding the physical constraints of it. I will argue that allowing machine to learn predictive models of the world is key to significant progress in artificial intelligence, and a necessary component of model-based planning and reinforcement learning. The main technical difficulty is that the world is only partially predictable. A general formulation of unsupervised learning that deals with partial predictability will be presented. The formulation connects many wellknown approaches to unsupervised learning, as well as new and exciting ones such as adversarial training.

Yann LeCun is Director of AI Research at Facebook, and Silver Professor of Data Science, Computer Science, Neural Science, and Electrical Engineering at New York University. He received the Electrical Engineer Diploma from ESIEE, Paris in 1983, and a PhD in Computer Science from Université Pierre et Marie Curie (Paris) in 1987. After a postdoc at the University of Toronto, he joined AT&T Bell Laboratories in Holmdel, NJ in 1988. He became head of the Image Processing Research Department at AT&T LabsResearch in 1996, and joined NYU as a professor in 2003, after a brief period as a Fellow of the NEC Research Institute in Princeton. From 2012 to 2014 he directed NYU’s initiative in data science and became the founding director of the NYU Center for Data Science. He was named Director of AI Research at Facebook in late 2013 and retains a part-time position on the NYU faculty. His current interests include AI, machine learning, computer perception, mobile robotics, and computational neuroscience. He has published over 180 technical papers and book chapters on these topics as well as on neural networks, handwriting recognition, image processing and compression, and on dedicated circuits for computer perception.

Improved Dropout for Shallow and Deep Learning Zhe Li (The Univ. of Iowa) Boqing Gong (Univ. of Central Florida) Tianbao Yang (Univ. of Iowa)

Dropout has been witnessed with great success in training deep neural networks by independently zeroing out the outputs of neurons at random. It has also received a surge of interest for shallow learning, e.g., logistic regression. However, the independent sampling for dropout could be suboptimal for the sake of convergence. In this paper, we propose to use multinomial sampling for dropout, i.e., sampling features or neurons according to a multinomial distribution with different probabilities for different features/neurons. To exhibit the optimal dropout probabilities, we analyze the shallow learning with multinomial dropout and establish the risk bound for stochastic optimization. By minimizing a sampling dependent factor in the risk bound, we obtain a distribution-dependent dropout with sampling probabilities dependent on the second order statistics of the data distribution. To tackle the issue of evolving distribution of neurons in deep learning, we propose an efficient adaptive dropout (named \textbf{evolutional dropout}) that computes the sampling probabilities on-the-fly from a mini-batch of examples. Empirical studies on several benchmark datasets demonstrate that the proposed dropouts achieve not only much faster convergence and but also a smaller testing error than the standard dropout. For example, on the CIFAR-100 data, the evolutional dropout achieves relative improvements over 10\% on the prediction performance and over 50\% on the convergence speed compared to the standard dropout. #2

Communication-Optimal Distributed Clustering Jiecao Chen (Indiana Univ. Bloomington) He Sun (The Univ. of Bristol) David Woodruff Qin Zhang

Clustering large datasets is a fundamental problem with a number of applications in machine learning. Data is often collected on different sites and clustering needs to be performed in a distributed manner with low communication. We would like the quality of the clustering in the distributed setting to match that in the centralized setting for which all the data resides on a single server. In this work, we study both graph and geometric clustering problems in two distributed models: (1) a point-to-point model, and (2) a model with a broadcast channel. We give protocols in both models which we show are nearly optimal by proving almost matching communication lower bounds. Our work highlights the surprising power of a broadcast channel for clustering problems; roughly speaking, to cluster n points or n vertices in a graph distributed across s servers, for a worst-case partitioning the communication complexity in a point-to-point model is ns, while in the broadcast model it is n + s. We implement our algorithms and demonstrate this phenomenon on real life datasets, showing that our algorithms are also very efficient in practice.
