Open letter: A commitment to open source in neuroscience

by Andrew Davison

Dear colleagues, We would like to point the members of this list to an initiative which resulted from a workshop on collaborative model development <https://www.janelia.org/you-janelia/conferences/collaborative-development-d…> at Janelia Research Campus. A number of participants agreed to sign an open letter committing to releasing as open source all the software they develop for data analysis and modelling in their publications (whether or not the article is specifically about the software). The letter and current signatories can be found here: http://opensourceforneuroscience.org/ <http://opensourceforneuroscience.org/> A NeuroView article describing this initiative has just been published in Neuron: A Commitment to Open Source in Neuroscience <http://www.cell.com/neuron/fulltext/S0896-6273(17)30981-9>. While many on this list are already sold on the idea of making their own code publicly available, there is another significant statement in the open letter: "If and when asked to serve as peer-reviewers, we will henceforth ask authors about the availability of any code they have developed for data analysis and modelling which is essential to reproducing the results of their paper and require that this be shared publicly upon acceptance." We hope that this public commitment will make it clear to the wider neuroscience community that trying to publish work on the assumption that they will not have to release their code will become more and more difficult, and that the sooner they plan to make it available the better for them and for the wider field. Regards, Padraig Gleeson Andrew P. Davison R. Angus Silver Giorgio A. Ascoli

CFP, Special session - Hybrid Life: Approaches to integrate biological, artificial and cognitive systems, ALife 2018

by Manuel Baltieri

[Apologies for cross-posting] ********** Call for Papers ********** Special session - Hybrid Life: Approaches to integrate biological, artificial and cognitive systems https://sites.google.com/view/hybrid-life/ <https://sites.google.com/view/hybrid-life/> 2018 Artificial Life conference (ALife) Tokyo, JAPAN, 23-27 July 2018 - http://2018.alife.org/ <http://2018.alife.org/> --------------------------------------------------------------------------------------------- DESCRIPTION: The main focus of ALife research is the study of natural systems with the goal of understanding what life is. More concretely, ALife defines ways to investigate processes that contribute to the formation and proliferation of living organisms. In this session we focus on three common approaches to tackle this investigation, proposing ways to integrate, extend and possibly improve them. More specifically we refer to: 1) the formalisation of the necessary properties for the definition of life, 2) the implementation of artificial agents, and 3) the study of the relation between life and cognition. For this special session we propose to start from these well-established Alife methodologies, and extend them through: a unified formal language for the description and modelling of living, as well as artificial and cognitive systems, e.g. control theory, Bayesian inference, dynamical systems theory, etc., the exploration of biological creatures enhanced by artificial systems (or artificial systems augmented with organic parts) in order to investigate the boundaries between living and nonliving organisms, and the evaluation of coupled biological-artificial systems that could shed light on the importance of interactions among systems for the study of living and cognitive organisms. This special sessions aims to invite contributions from the fields of psychology, computational neuroscience, HCI, theoretical biology, artificial intelligence, robotics and cognitive science to discuss current research on the formalisation, combination and interaction of artificial/living/cognitive systems from theoretical, modelling and implementational perspectives. Potential topics include, but are not limited to: Formalisation of life and cognition (e.g. dynamical systems theory, stochastic optimal control, Bayesian inference, etc.) Cognitive robotics Autopoiesis Life-mind continuity thesis Systems biology Origins-of-life theories with relationships to artificial and cognitive systems Animal-robot interaction Bio-inspired robotics Bio-integrated robotics Human-machine interaction Augmented cognition Sensory substitution Interactive evolutionary computation Artificial perception Important Dates 19th March 2018 – Paper submission deadline 23rd April 2018 – Paper acceptance notification 21st May 2018 – Camera-ready version 23-27th July 2018 – Artificial Life conference (ALife), Tokyo, Japan Paper Submission Papers and abstracts submitted to this special sessions will be reviewed by a selected group of experts from the a-life community as well as from other areas key to our proposal, specifically chosen for this review process. If you are submitting to a special session you will be given the opportunity to select it during the submission process. Submissions to special sessions follow the same format, instructions and deadlines of regular ALife papers.

CFP: Special Session on “Neural Models for Behavior IJCNN 2018

by Pablo Barros

Call for papers: special session on “Neural Models for Behavior Recognition” at IJCNN 2018 - http://www.ecomp.poli.br/~wcci2018/ International Joint Conference on Neural Networks, hosted at IEEE World Congress on Computational Intelligence (IEEE WCCI 2018) 8-13 July 2018, Rio de Janeiro, Brazil Special Session on Neural Models for Behavior Recognition Organized by: Pablo Barros (Universität Hamburg, Germany), Bruno Fernandes (Universidade de Pernambuco, Brazil) and Stefan Wermter (Universität Hamburg, Germany) Categorizing and, to a certain degree, understanding human behavior is an important skill for autonomous systems. A robot able to identify whether a person needs help, an autonomous car to perceive whether a pedestrian is crossing the road, or a camera to localize someone in danger need a robust and reliable human behavior understanding. Although many different solutions have appeared in the past years, most of them do not take longer contextual information into consideration, usually only relying on instantaneous or short-context scenarios which limits the applicability of such systems in a real-world scenario. The potential of having neural models that take into consideration contextual information is substantial and it would be beneficial to develop this technology further for this field. To have a system which is capable of learning, understanding and generalizing human behavior within a longer contextual scene is a challenging task. With recent neural computing technologies, such as training and understanding deep neural networks, life-long learning and unsupervised approaches, to name a few, we believe that autonomous systems which are capable of learning from long-context human behavior are feasible. This kind of processing would provide contextual information which would be beneficial to understanding and acting in real-world scenarios. We invite papers on both practical and theoretical issues about neural learning for behavior recognition. In particular, topics of interest include, but are not limited to: - Gesture processing, recognition and/or generation - Models for emotional behavior analysis and/or understanding - Speech based sentiment analysis and/or dialog processing - Action recognition and/or generation - Crossmodal human behavior learning - Temporal architectures for human behavior learning - Emotional feedback and modulation in decision-making processes - Life-long learning for human behavior processing Submitted papers will be reviewed according to the IJCNN reviewing process and will be evaluated on their scientific value: originality, correctness, and writing style.

PhD studentship in Biocomputation Research Group, Centre for Computer Science and Informatics Research, University of Hertfordshire

by Shabnam Kadir

Applications are invited for a *PhD studentship* on *Computational frameworks for high-dimensional neural data* with *Dr. Shabnam Kadir *in the *Biocomputation Research Group* in the Centre for Computer Science and Informatics Research, University of Hertfordshire, U.K. *Project Description* New developments in experimental technology have led to petabytes of raw data being produced by experimental neuroscientists, which are increasingly publicly available, e.g. Allen Institute data http://www.brain-map.org/. In particular, we are in the realm where population recordings of tens of thousands of neurons are feasible thanks to, e.g. a new generation of large dense probes for electrophysiological recordings, imaging using 2-photon microscopy coupled with calcium fluorescent sensors. Large scale neuronal recordings require novel approaches for both processing and quantitative analysis. As well as using techniques from high-dimensional statistics, machine learning, information theory, we aim to explore new approaches from mathematical fields outside statistics, such as algebraic topology. The study of networks is a particularly important topic in neuroscience: neurons communicate with each other electrically via synapses, forming intricate networks. These networks can be studied using techniques from computational topology (e.g. persistent homology, clique topology). These could be used to extract information about subnetworks and assemblies, both from large scale recordings, and via connectomics derived from simulations (Blue Brain Project). We aim in this project to go beyond spike sorting and develop new tools and computational frameworks which would help interpret high dimensional data and interrogate how information is being processed by the brain, e.g. How are sensory stimuli (location in environment, visual and auditory stimuli) encoded? How can we characterise the neural activity associated with memory, attention, decision making and motor control? We shall be collaborating with labs at Imperial, Pennsylvania State University and UCL. More information can be found here: http://www.herts.ac.uk/_ _data/assets/pdf_file/0003/187455/Dec2017-computational-frameworks-for-high- dimensional-neural-data.pdf *Requirements * We are looking for candidates with the following profile: - Strong first degree in a quantitative field such as mathematics, physics, computer science, engineering, computational neuroscience. - Strong programming skills (e.g. Python, MATLAB, C++). - Interest in neuroscience and biology would be helpful. A studentship from the PhD Programme in Computer Science provides approximately £14,550 per annum bursary plus the payment of student fees. Applicants from outside the UK or EU are eligible. Research in Computer Science at the University of Hertfordshire has been recognised as excellent in the latest Research Excellence Framework Assessment, with 50% of the research submitted rated as internationally excellent or world-leading. The Centre for Computer Science and Informatics Research provides a very stimulating environment, offering a large number of specialised and interdisciplinary seminars as well as general training and researcher development opportunities. The University is situated in Hatfield, in the green belt just north of London. Please contact *Dr Shabnam Kadir* (shabnam.kadir(a)imperial.ac.uk) for informal enquiries.
