The below vacancy in the Applied Statistics Center at Columbia University may be of interest to CSML members
We’re working with polling company YouGov to track public opinion, state-by-state and district-by-district, during the 2014 campaign. We’ll be using multilevel regression and poststratification, and implementing it in Stan, and developing the necessary new parts of Stan to get this running scalably and efficiently. And we’ll be making the most detailed, up-to-date election forecasts.
What you’ll be doing if you join us as a postdoc:
- You’ll be in the midst of the most advanced polling team anywhere;
- You’ll be doing cutting-edge statistical research on MRP with deep interactions;
- You’ll be doing basic research in statistical computing, developing fast and scalable deterministic and stochastic algorithms for fitting multilevel models;
- You’ll be working inside Stan, the most advanced general computational framework for Bayesian analysis. We’re doing research, not just implementing existing methods.
What we need:
- Stats knowledge. You should know your way around Bayesian data analysis;
- Serious computing skills. You should be a skilled C++ programmer;
- Interest in the application area. You should care about public opinion, and it should be important to you that our forecasts are good. When our estimates of opinion for some group in the population don’t make sense, you should notice and be bothered by it.
We have a great team with diverse skills (computing, statistics, political science) that plays nicely together and from whom you can learn a lot. Also lots of opportunity to collaborate with researchers in many different quantitative disciplines through Columbia’s Applied Statistics Center.
The position is a 2-year postdoc, funded by Yougov and situated in the Applied Statistics Center at Columbia University. More details on the position can be found at http://andrewgelman.com/2014/01/15/postdoc-involving-pathbreaking-work-mrp-stan-2014-election/ .
The Amazon Machine Learning Science Team is seeking interns to join the Scalable Machine Learning, Forecasting, Content Linkage, and Computer Vision groups in Berlin, Germany. We focus on data-driven approaches in these areas for Amazon as a whole as well as their applications to particular products.
- In the Forecasting group, we develop sophisticated algorithms that involve learning from very large amounts of data, such as prices, promotions, similar products, and a product’s attributes, in order to forecast the demand of over 10 million products. These forecasts are used to automatically order more than $200 million worth of inventory weekly, establish labor plans for over 10,000 employees, and predict the overall company’s financial performance. The work is complex and important to Amazon. The better our forecasts, the more we can lower prices for customers and offer in-stock selection.
- In the Content Linkage group, our goal is to learn to dynamically link digital content on Amazon and the Web, so that customers can discover fresh and related content relevant to books and other media they purchase. Our other task is to enable fast and scalable translation of Amazon's product catalog, customer reviews and other natural language data across a large number of language pairs.
- In the Computer Vision group our goal is to develop real-time object recognition and object tracking algorithms that can distinguish between 10+M products and can be used to automate Amazon's fulfillment and product quality systems. The more accurately we can detect products, the more we can speed-up the delivery to customers.
- In the Scalable Machine Learning group, we develop learning algorithms able to handle the gigantic data volumes collected by Amazon and able to operate at internet speed. We explore new paradigms for distributed optimisation and inference. We also investigate efficient representations of very large and complex data models. Finally, we automate the process of building and learning data models to enable evidence-driven decision-making with minimal effort from the domain experts.
Please contact Cedric Archambeau cedrica(at)amazon.de if you are interested in this opportunity.

The main objective is to develop and characterise principled approximations to complex statistical models.
The research work aims to reduce both the variance of simulation-based estimates, and the computational time of stochastic algorithms. This will facilitate the implementation of stochastic models in real biological applications. The grant will support a postdoctoral researcher for three years.
Funded by EPSRC for 3 years
ENGAGE: Interactive Machine Learning Accelerating Progress in Science, An Emerging Theme of ICT Research In short, it brings together Machine Learning, Computer Vision, Human-Computer Interaction, and Biodiversity Science to help cope with the global extinction crisis.
The PI's on the project are:
Gabriel Brostow - UCL CS
Mark Girolami - UCL Stats
Kate Jones - UCL Department of Genetics, Evolution and Environment Mike Terry - University of Waterloo, CS and ZSL Chair, Ecology and Biodiversity
Our vision is to establish and lead a new theme in ICT research based on Interactive Machine Learning (IML). Our expansion of IML will give scientists and non-ICT specialists unprecedented access to cutting-edge Machine Learning algorithms by providing a humancomputer interface by which they can directly interact with large scale data and computing resources in an intuitive visual environment. In addition, the outcome of this particular project will have a direct transformative impact on the sciences by making it possible for non-programming individuals (scientists), to create systems that semi-automatically detect objects and events in vast quantities of A) audio and B) visual data.
By working together across two parallel, highly interconnected streams of ICT research, we will develop the foundations of statistical methodology, algorithms and systems for IML. As an exemplar, this project partners with world leading scientists grappling with the challenge of analysing enormous quantities of heterogeneous data being generated in Biodiversity Science.
Please go to http://www.i-like.org.uk/launch-day-31st-january-2013.html for details of this event.
The day is principally aimed at phd and post doc level, although others are more than welcome to attend as well.
The Gatsby Computational Neuroscience Unit at University College London is looking to recruit a junior or senior level faculty member in machine learning or statistics. We especially seek candidates who work in probabilistic or statistical machine learning.
The closing date for applications is 20 December 2012
