[job] Call for postdoc application on curiosity-driven deep reinforcement learning
by Pierre-Yves Oudeyer 18 Feb '19

18 Feb '19

Call for postdoc application Topic: Intrinsically motivated multi-goal deep reinforcement learning in open virtual worlds Host and location: Inria Flowers Lab, Bordeaux, France Collaboration with Ubisoft (Bordeaux) Supervision: Pierre-Yves Oudeyer (Flowers team, Inria and Ensta ParisTech) Duration: between 18 months and 2 years Deadline for application: the position will be assigned and start as soon as possible (from april or may 2019). This postdoc project aims to develop autonomous lifelong machine learning techniques that enable virtual intelligent agents to make discoveries and acquire large repertoires of skills in open uncertain environments. This is key for developing agents that need to continuously explore and adapt interaction skills to new or changing tasks, environments, people to interact with, and preferences of others. The approach will leverage recent advances in curiosity-driven developmental learning (also called intrinsically motivated learning) to drive exploration in a multi-goal deep reinforcement learning framework. In particular, it will consist in studying several extensions of recent results of the Flowers lab in this area, including unsupervised learning of goal spaces using deep learning approaches (Laversanne-Finot et al., 2018) and the CURIOUS algorithm for intrinsically motivated multi-task multi-goal deep RL (Colas et al., 2019). These algorithms will be evaluated on benchmarks involving novel virtual environments dedicated to study exploration and curiosity (e.g. based on Unity3D MLagents), as well as modern open world video games in the context of a collaboration with Ubisoft (Bordeaux). Keywords : Deep RL, neural networks, multi-task learning, transfer learning, curiosity, intrinsic motivation, curriculum learning, Unity3D. Required knowledge and background: Candidates should already have shown very strong experience and achievements, shown by publications in top-tier AI/machine learning conferences and journals (e.g. NIPS, ICML, ICLR) in either: - Deep Learning algorithms (theory and practical implementations) - Reinforcement learning Other requirements: - strong skills in mathematics, statistical inference, machine learning - Advanced programming skills - Motivation to work in an interdisciplinary project Contact and application: Send CV and letter of motivation to pierre-yves.oudeyer(a)inria.fr Web: Inria Flowers: http://flowers.inria.fr and http://www.pyoudeyer.com The Flowers Lab: developmental robotics and lifelong multitask machine learning ================================================================== The Flowers Lab, headed by Pierre-Yves Oudeyer, gathers a team of ~20 members and has been one of the pioneers of developmental robotics and lifelong machine learning and artificial intelligence in the last decade, in particular through developping models of intrinsically motivated learning of repertoires of skills that have both contributed to advance understanding of human curiosity and development, and to advance incremental online multitask machine learning techniques in difficult high-dimensional robotic spaces. This work in the Flowers lab is conducted in the context of large international projects (e.g. ERC grant, European projects 3rdHand and DREAM, HFSP project Neurocuriosity), with interdisicplinary collaborations with other labs in neuroscience, psychology, machine learning and robotics. The successful candidates would be directly involved in these international collaborations. The Flowers lab has recently spin-off the Pollen Robotics startup company, and is involved in multiple collaborations with industrials through Inria's strong support towards impacting both science and industry. Inria and EnstaParistech =================== The lab is within Inria Bordeaux, which is a prestigious, and also the largest, public European research insitution focused on computer science, mathematics and their applications.

position: machine learning research scientist at NIMH
by Francisco Pereira 15 Feb '19

15 Feb '19

The Machine Learning Team at the National Institute of Mental Health (NIMH) in Bethesda, MD, has an open position for a machine learning research scientist. The NIMH is the lead federal agency for research on mental disorders, and part of the the National Institutes of Health (NIH). Our mission is to help NIMH scientists use machine learning methods to address a diverse set of research problems in clinical and cognitive psychology and neuroscience. These range from identifying biomarkers for aiding diagnoses to creating and testing models of mental processes in healthy subjects. We work with many different data types, including very large brain imaging datasets from various imaging modalities, behavioral data, and picture and text corpora. We also develop new machine learning methods and publish in the main machine learning conferences (e.g. NeurIPS and ICLR), and in psychology and neuroscience journals. Many of our problems require devising research approaches that combine imaging and non-imaging data, and leveraging structured knowledge resources (databases, scientific literature, etc) to generate explanations and hypotheses. We have excellent computational resources, both of our own (tens of GPUs for deep learning) and shared within the NIH (a top-100 supercomputer with hundreds of thousands of CPUs, and hundreds of GPUs). You can find more about our work and publications at https://cmn.nimh.nih.gov/mlt.html. This is an ideal position for someone who wants to establish a research career in methods development and applications driven by scientific and clinical needs. Given our access to a variety of collaborators and large/unique datasets, there is ample opportunity to match research interests with novel research problems. We also maintain collaborations outside of the NIH, driven by our own research interests. We are seeking candidates with practical machine learning experience (e.g. training of classification and regression models, statistical testing of results, interpretation and visualization of key aspects of models). Beyond this, the ideal candidate would have knowledge of optimization and statistics, insofar as they bear on machine learning methods development. Experience working with neuroimaging data (any MRI modality, as well as MEG/EEG) will be considered very favorably, but is not required. Finally, you should have demonstrable experience coding in languages currently used in data-intensive, scientific computing such as Python, MATLAB or R. If you would like to be considered for this position, please send francisco.pereira(a)nih.gov a CV, with your email as cover letter; if you have a research statement, please feel free to send that as well. Other inquiries are also welcome. Thank you for your interest!
