Alex Matthews has been given a software award from the Google Open Source Programs Office for his work on TensorFlow. The award is for “…people outside of Google that they thought were doing great things in the world of open source”, in particular for his work implementing Cholesky backpropagation. The work removes one of the main barriers to implementing Gaussian processes in TensorFlow and is part of the ongoing GPflow project.

We are delighted to announce that Dr. José Miguel Hernández-Lobato will join Cambridge MLG as a University Lecturer in Machine Learning later this year. Miguel joins us from Harvard and has a broad range of interests in probabilistic machine learning. For more details see his website.
Cambridge Machine Learning Group has a strong involvement with the new Alan Turing Institute. The ATI is the national institute for research in Data Science and is headquartered in London. It brings together researchers from five top British universities: the Universities of Cambridge, Edinburgh, Oxford, and Warwick, and University College London.
Our own Prof. Zoubin Ghahramani has been appointed University of Cambridge Liason Director.
Group members Prof. Carl Rasmussen and Dr. Adrian Weller have been appointed as ATI Faculty Fellows.
Well done to Yarin Gal who has been awarded the Michael and Morven Heller Research Fellowship at St Catherine’s College, Cambridge.
The fellowship is awarded to
“… exceptional candidates in the field of Computer Science including those who will apply Computer Science to ‘big data’ in all fields including biomedical sciences generally.”
Microsoft Research, Cambridge and the University of Cambridge Machine Learning Group have organized a Machine Learning and Artificial Intelligence workshop on Friday March 18th 2016 at the public facilities of Microsoft Research Cambridge. The day will feature talks from both research groups and representatives of local startups.
Attendance is open to the public but requires prior registration. More details, including a schedule for the day can be found here.
We are seeking up to three highly creative and motivated Postdoctoral Research Assistants/Associates to join the Machine Learning Group in the Department of Engineering, University of Cambridge, UK. All positions will involve research in direct collaboration with Professor Zoubin Ghahramani.
Post 1: Building an Automatic Statistician and Probabilistic Programming. This post holder will be working on developing algorithms for the automated analysis and interpretation of data in collaboration with MIT. Candidates should have extensive experience in probabilistic modelling, scalable approximate inference, and existing probabilistic programming languages. See: http://www.automaticstatistician.com/
Post 2: Bayesian Nonparametrics. This post holder will be working with foundations, models and inference algorithms for Bayesian Nonparametrics. Candidates should have research experience in Bayesian nonparametrics and MCMC methods.
Post 3: Deep Probabilistic Models for Making Sense of Unstructured Data. This post holder will be working on deep learning, probabilistic modelling and privacy-preserving machine learning in a collaboration between Professor Ghahramani and Professor Neil Lawrence’s group.
The successful applicants will have or be near completing a PhD in computer science, information engineering, statistics or a related area, and will have extensive research experience and a strong publication record in machine learning, including ideally papers in top machine learning conferences such as NIPS, UAI, ICML, and AISTATS.
If you have any questions about this vacancy or the application process, please contact Miss Diane Hazell, email: email@example.com, Tel: +44 01223 748529. To apply you must upload your information via: http://www.jobs.cam.ac.uk/job/9649/
The deadline for applications is 6 April 2016.
MLG alumni Dr James Robert Lloyd and Dr Alex Davies have helped create the world’s first musical largely created by computer, in work which began whilst they were in Cambridge. Together with Professor Sir David Spiegelhalter they began by analysing factors associated with success and failure in musical theatre. This analysis was then used to guide the creation of content for the musical, including using a recurrent neural network language model trained on musical theatre lyrics.
The musical, Beyond the Fence, will be showing at the Arts Theatre in London’s West End from 22nd February to 5th March. Full details can be found here.
Five new papers from the group are to appear at the 2016 International Conference on Artificial Intelligence and Statistics (AISTATS) to be held in May in Cadiz, Spain.
The list of papers are:
Jes Frellsen, Ole Winther, Zoubin Ghahramani, Jesper Ferkinghoff-Borg.
Bayesian generalised ensemble Markov chain Monte Carlo.
Alexander G. de G. Matthews, James Hensman, Richard E. Turner, Zoubin Ghahramani.
On Sparse Variational Methods and the Kullback-Leibler Divergence between Stochastic Processes.
Robert Nishihara, David Lopez-Paz and Léon Bottou.
No regret bound for extreme bandits.
Adrian Weller, Justin Domke.
Clamping Improves TRW and Mean Field Approximations.
Adrian Weller, David Sontag.
Tightness of LP Relaxations for Almost Balanced Models.
For the most up to date versions of the papers, visit the authors’ webpages, which may be found through our group members page.
Congratulations to Professor David MacKay who has been awarded a Knighthood in the 2016 New Years honours list. More information on the story can be found here.
