Abstract

Over the recent years, we have seen significant advances in speech recognition, language and dialog technologies. Voice-enabled personal assistants are now deployed in the hands of millions of people. At the same time, numerous challenges remain largely unaddressed in the realm of physically situated language interaction (e.g., in-car systems, robots in public spaces, ambient assistance). In this talk, I will highlight some of these challenges. I will outline a set of basic skills required for supporting dialog in physically situated settings, and I will highlight the importance of fine-grained timing and coordination in regulating language interaction processes like engagement and turn-taking.

Jasmin Fisher | Microsoft Research

jasmin-fisher100x132Cancer AI

Abstract

Cancers are pathologies driven by genetic mutations that disrupt a multitude of signalling pathways operating across different cell types interacting in highly complex ways. No two cancers, even of the same type, are the same. The holy grail of cancer treatment is to analyse the patient’s genome and predict a sequence and combination of therapies that will destroy that patient’s cancer with no adverse side effects. By developing executable models that can simulate cancer tumours at different levels of abstraction, we are on the threshold of being able to deliver on this vision. The state-of-the-art in executable biology is the use of formal methods and software verification to describe biological systems and explore their properties. Using program synthesis methods we can directly build such models from patients’ data. This approach has already been used to find new more efficient therapies for Leukaemia in partnership with AstraZenenca. The next big question, as we collect more and more patient genomic data and history of cancer treatments, is how can we use AI methods to drive therapeutic regimes directly from patients’ data? In the talk, I will showcase recent results and share some of the ambitions in this space.

Iain MurrayMonte Carlo and Machine Learning

View the slides

Abstract

“Monte Carlo” methods use random sampling to understand a system, estimate averages, or compute integrals. Monte Carlo methods were amongst the earliest applications run on electronic computers in the 1940s, and continue to see widespread use and research as our models and computational power grow. In machine learning, random sampling is widely used within optimisation methods, and as a way to perform inference in probabilistic models. Here “inference” simply means obtaining multiple plausible settings of model parameters that could have led to some observed data. Obtaining a range of explanations tells us both what we can and cannot know from our data, and prevents us from making overconfident (wrong) predictions.

This talk will describe some current research areas in Monte Carlo methods, and their interaction with machine learning.

Olya OhrimenkoConfidential Machine Learning in the Cloud

Abstract

In this talk, I will focus on techniques that allow one to use cloud computing infrastructure for running machine learning algorithms on sensitive and confidential datasets in a secure and privacy-preserving manner. Our goal is to provide users of cloud computing with complete control over their data: no one, including malicious employees and hackers, should be able to access the data without the user’s permission. We start off by isolating machine learning (ML) code and data from the rest of the cloud environment using encryption and secure hardware (for example, Intel SGX). Though this essential step reduces the attack surface significantly, the interaction of the code with untrusted environment via data-dependent accesses to memory can leak confidential information. To this end, we propose data-oblivious counterparts of several machine learning algorithms, including decision trees and neural networks. These algorithms are designed to access memory without revealing secret information about their input. We use algorithmic techniques as well as platform specific hardware features to ensure that only public information, such as dataset size, is revealed. We will see that an efficient implementation of our framework on Intel Skylake processors scales up to realistic datasets, with overheads several orders of magnitude lower than with cryptographic-based approaches.

Biography

How to Give a Great Research Talk

View the slides

Abstract

Writing papers and giving talks are key skills for any researcher, but they aren’t easy. In this pair of presentations, I’ll describe simple guidelines that I follow for writing papers and giving talks, which I think may be useful to you too. I don’t have all the answers-far from it-so I hope that the presentation will evolve into a discussion in which you share your own insights, rather than a lecture.

Biography

Simon Peyton Jones, MA, MBCS, CEng, graduated from Trinity College Cambridge in 1980. After two years in industry, he spent seven years as a lecturer at University College London, and nine years as a professor at Glasgow University, before moving to Microsoft Research in 1998. His main research interest is in functional programming languages, their implementation, and their application. He has led a succession of research projects focused around the design and implementation of production-quality functional-language systems for both uniprocessors and parallel machines. He was a key contributor to the design of the now-standard functional language Haskell, and is the lead designer of the widely used Glasgow Haskell Compiler (GHC). He has written two textbooks about the implementation of functional languages. More generally, he is interested in language design, rich type systems, software component architectures, compiler technology, code generation, runtime systems, virtual machines, garbage collection, and more. He is particularly motivated by direct use of principled theory to practical language design and implementation-that’s one reason he loves functional programming so much. He is also keen to apply ideas from advanced programming languages to mainstream settings.

Confidentiality and Privacy Threats in Machine Learning

View the slides

Abstract

Machine learning models are increasingly deployed widely, necessitating an understanding of the often nuanced interplay between ML and security. In this talk, I’ll provide a brief introduction to some recent research trends in ML security, and then focus on those that deal with confidentiality and privacy.

First, I will discuss recent work showing how to steal machine learning models from prediction APIs. We show simple approaches for extracting near-exact replicas of target linear models, neural networks, and decision trees from production machine learning cloud services such as Amazon Prediction API and BigML.  I’ll then explore one specific privacy threat that arises from access to models, what we call model inversion. In the model inversion attacks we develop, an adversary can exploit access to a model and some partial information about a person to improve their ability to guess sensitive information about that person, such as a recognizable image of their face, their genotype, or private lifestyle behaviours. Finally, I will discuss the ability of malicious training algorithms to exfiltrate training data using the spare capacity of typical machine learning models.

Biography

Thomas Ristenpart is an Associate Professor at Cornell Tech and a member of the Computer Science department at Cornell University. Before joining Cornell Tech in May, 2015, he spent four and a half years as an Assistant Professor at the University of Wisconsin-Madison.

Abstract

Many real-world problems, such as network packet routing and the coordination of autonomous vehicles, are naturally modelled as cooperative multi-agent systems. In this talk, I overview some of the key challenges in developing reinforcement learning methods that can efficiently learn decentralised policies for such systems. I also propose a new multi-agent actor-critic method called counterfactual multi-agent (COMA) policy gradients. COMA uses a centralised critic to estimate the Q-function and decentralised actors to optimise the agents’ policies.  In addition, to address the challenges of multi-agent credit assignment, it uses a counterfactual baseline that marginalises out a single agent’s action, while keeping the other agents’ actions fixed. COMA also uses a critic representation that allows the counterfactual baseline to be computed efficiently in a single forward pass. Finally, I present results evaluating COMA in the testbed of StarCraft unit micromanagement.

Distributed Bayesian Learning with Stochastic Natural-gradient Expectation Propagation and the Posterior Server

Abstract

View the slides

We make two contributions to Bayesian machine learning algorithms. Firstly, we propose stochastic natural gradient expectation propagation (SNEP), a novel alternative to expectation propagation (EP), a popular variational inference algorithm. SNEP is a black box variational algorithm, in that it does not require any simplifying assumptions on the distribution of interest, beyond the existence of some Monte Carlo sampler for estimating the moments of the EP tilted distributions. Further, as opposed to EP which has no guarantee of convergence, SNEP can be shown to be convergent, even when using Monte Carlo moment estimates.

Secondly, we propose a novel architecture for distributed Bayesian learning which we call the posterior server. The posterior server allows scalable and robust Bayesian learning in cases where a dataset is stored in a distributed manner across a cluster, with each compute node containing a disjoint subset of data. An independent Markov chain Monte Carlo (MCMC) sampler is run on each compute node, with direct  access only to the local data subset, but which targets an approximation to the global posterior distribution given all data across the whole cluster. This is achieved by using a distributed asynchronous implementation of SNEP to pass messages across the cluster. We demonstrate SNEP and the posterior server on distributed Bayesian learning of logistic regression and neural networks.

Steve YoungApplications of Deep Learning in Spoken Dialogue Systems

View the slides

Abstract

Spoken dialogue systems (SDS) provide the core enabling technology for building intelligent personal assistants.  The function of an SDS is to understand each user input, decode the users intention or goal and then respond accordingly. Whereas historically much of this functionality has been provided by hand-crafted rule systems, modern systems increasingly rely on statistical models and machine learning. This talk will briefly review the structure and components of a modern SDS and show how they can be implemented using deep neural networks. The provision of adequate quantities of annotated training data is a major limitation on progress and the talk will conclude with some recent work on end-to-end training which has the potential to greatly reduce or even eliminate the need for labelled data.
