[Call for postdoc application] Automated discovery of physico-chemical structures with intrinsically motivated deep learning algorithms

by Pierre-Yves Oudeyer

Call for postdoc application: Automated discovery of physico-chemical structures with intrinsically motivated deep learning algorithms Project Team Inria: Flowers, Inria Bordeaux, https://flowers.inria.fr Contact: Pierre-Yves Oudeyer, pierre-yves.oudeyer(a)inria.fr Deadline for applying: 19th april 2018 How to apply: send email to PY Oudeyer and post application to https://jobs.inria.fr/public/classic/fr/offres/2018-00413 Duration: 16 months Scientific context: Intrinsically motivated goal exploration algorithms enable machines to discover repertoires of action policies that produce a diversity of effects in complex environments. In robotics, these exploration algorithms have been shown to allow real world robots to acquire skills such as tool use in high-dimensional continuous state and action spaces (e.g. Baranes and Oudeyer, 2013; Forestier et al., 2017). An example is the Poppy/Explauto experiment with a humanoid robot learning to use tools in a few hours, which obtained the 2nd position in the demonstration competition at NIPS 2016 (See https://www.youtube.com/watch?v=NOLAwD4ZTW0 , Forestier et al., 2016). In other domains such as chemistry and physics, they open the possibility to automate the discovery of novel chemical or physical structures produced by complex dynamical systems (e.g. Grizou, Points et al., 2017) However, they have so far assumed that self-generated goals are sampled in a specifically engineered feature space, limiting their autonomy. Recent work has shown how unsupervised deep learning approaches could be used to learn goal space representations (e.g. Péré et al., 2018), but they have focused on goals represented as static target configurations of the environment in robotics sensorimotor spaces. In this project, we will study how these new families of machine learning algorithms can be extended and used for automated discovery of behaviours of dynamical systems in physics/chemistry, through exploration of their parameter space, and when these behaviours are perceived through raw sensors (e.g. pixels of images). Web site of Flowers Lab: https://flowers.inria.fr Post-doctoral researcher work description The work will begin by a familiarization with algorithms for intrinsically motivated exploration with unsupervised learning of goal spaces developed in the team. Then, a few interesting numerical/simulation models of physical/chemical phenomena, associated to rich behavioral patterns (such as Turing-like reaction-diffusion models or oil droplet models), will be selected as a basis for developing and experimenting updates of existing exploration and learning algorithms. These algorithmic updates will focus in particular on the use of recurrent neural networks to learn goal spaces that can encode dynamical phenomena. Several algorithmic implementations will be compared, e.g. using several techniques for encoding times series as goal spaces, and compared using various information theoretic measures of the diversity of discovered behaviours in the target dynamical systems. It will be also possible to test these algorithmic updates in more traditional (simulated) sensorimotor learning problems, using standard benchmarks of the literature (e.g. Open Gym environments or Minecraft/Malmo). Experiments will possibly extend the DeepExplauto open-source library developed in the team, as well as standard Deep Learning libraries for the algorithms. Required knowledge and background: Candidates should have a strong expertise in at least one of these areas: - Experience with Deep Learning algorithms (theory and practical implementations) - Stochastic optimization, black-box optimization - Intrinsically motivated exploration algorithms Knowledge and competence in physics/chemical modelling would be welcome. Other requirements: - strong skills in mathematics, statistical inference, machine learning - Advanced programming skills in script languages like python - Motivation to work in an interdisciplinary project References : Baranes, A., & Oudeyer, P.

Fruit Fly Brain Hackathon 2018

by Yiyin Zhou

Fruit Fly Brain Hackathon 2018 FFBH 2018 <http://fruitflybrain.org/hackathons>March 14, 2018Columbia University, New York, NY 10027 We are pleased to announce the 3rd Fruit Fly Brain Hackathon (FFBH 2018). This hackathon will be focused on open neurophysiology data (electrophysiology, imaging, etc.) of, but not limited to, the fruit fly brain. The hackathon will be focused on the following topics: 1. Promoting *Neurodata Without Board* (NWB) as a standard format for storing and sharing neurophysiology data in general, and extend it to standardize the storage and distribution of fruit fly brain electrophysiology and calcium imaging data, 2. *Queryable* neurophysiology data: organizing neurophysiology data and metadata in a database to make them easily queryable, and developing comprehensive querying tools accordingly, 3. Incorporating queried neurophysiology data into computational study. The goals are to: 1. create a common language for sharing open neurophysiology data, 2. speed up pattern search in the data that can often be tedious and inefficient to do manually, 3. drive the creation of computational models and the validation of them using open data. The hackathon is aimed at three main groups of participants: neurobiologists, modelers and software engineers. We welcome researchers working on the fruit fly brain as well as those working on other model organisms to participate and broaden the discussion in the hackathon. The Fruit Fly Brain Hackathon 2018 is organized in conjunction with the Columbia Workshop on Brain Circuit, Memory and Computation on March 15-16, 2018. Participants of the hackathon are welcome to attend the workshop. Registration is free but all participants have to register <https://ffbh2018.eventbrite.com/> (*https://ffbh2018.eventbrite.com/ <https://ffbh2018.eventbrite.com/>*).
