Computational Psychiatry – Day 1 Monday, March 3, 2014 Organizers: Quentin Huys, ETH Zurich Tiago Maia Computational techniques have become increasingly important to neuroscience. Over the past few years, researchers have started to fruitfully apply such techniques to mental health, with applications in clinical practice now coming into reach. The approaches are fascinatingly diverse, spanning many imaging modalities, multiple levels of characterization of brain function and a vast array of computational and machine learning techniques. The workshop at Cosyne will bring together a large fraction of the key workers from across the spectrum of the field. Though nascent, computational psychiatry is a rapidly growing field and now is maybe the last opportunity for a reasonably comprehensive overview. Given the scope and breadth of questions and methods, such an overview is hard to fit into one day in a cohesive manner, and we have thus prepared a two-day workshop. It is important that this workshop should be held as part of Cosyne: it is one of the conferences with the most applicable broad technical skill sets for the problem at hand; the neuroscience of mental health is of genuine interest to the Cosyne community at large; and it is probably the main health sector to which insights gained in the Cosyne community can be applied. We hope to contribute to the consolidation of the field and the clarification of the key solvable questions by bringing together scientists using different techniques and working on different aspects of the same problem at this critical time of expansion. The first day will focus particularly on reinforcement learning and decision-making approaches, while the second day will broaden the scope and encompass work ranging from explicit neural network models to large-scale models of social interactions in psychiatric populations. 6 Computational Psychiatry – Day 1 Wasatch A Morning session Decision-making approaches 8:00–8:05 am Quentin Huys and Tiago Maia, Welcome and overview 8:05–8:45 am Martin Paulus, The utility of computational psychiatry 8:45–9:25 am Angela Yu, Learning and decision-making in inhibitory control 9:25–9:40 am Coffee break 9:40–10:20 am Quentin Huys.

Information Sampling in Behavioral Optimization – Day 1 Monday, March 3, 2014 Organizers: Bruno Averbeck, National Institutes of Mental Health Robert C. Wilson, Princeton Neuroscience Institute Matthew R. Nassar, University of Pennsylvania All learning depends on information - without information there is nothing to learn. But gathering information can be costly and the desire to learn can be opposed by the need for speed or the desire for immediate reward. In this workshop we will examine the role of information sampling in two well-known behavioral problems: the speed-accuracy tradeoff and the explore-exploit dilemma. We will hear from researchers studying these problems across a wide range of species, from monkeys and humans to rats and worms. We will look at information sampling algorithms that solve these problems optimally and the extent to which neural circuits and neuromodulators support these algorithms in the brain. Our aim is to bring together a diverse set of participants, from the usual reinforcement learning and decision making crowd, to researchers interested in foraging and theorists interested in algorithms. In the spirit of exploration, most of the talks will be given by non-faculty members -- i.e. postdocs and graduate students. We believe that this focus on the first authors, rather than the last, will not only provide a welcome forum for new voices, but will also encourage fresh perspectives on these classic problems. To highlight the similarity of the two behavioral problems, we will interleave talks on the explore-exploit dilemma with talks on the speed-accuracy tradeoff and several talks will combine both. 8 Information Sampling in Behavioral Optimization – Day 1 Wasatch B Morning session 8:30–9:00 am Robert Wilson, Human strategies for solving the exploration-exploitation dilemma 9:05–9:35 am Steven Flavell, Serotonin and the neuropeptide PDF initiate and extend opposing behavioral states in C. elegans 9:55–10:25 am Shunan Zhang, Forgetful Bayes and myopic planning: human exploration and exploitation in bandit problems 10:30–11:00 am Paul Schrater, Optimal exploration driven by reward statistics Afternoon session 4:30–5:00 pm Erie Boorman, Frontal polar cortex and the evidence for changing future behavior 5:05–5:35 pm Andra Geana, Reward, Risk and Ambiguity in Human Exploration - A Wheel of Fortune Task 5:55–6:25 pm Vincent Costa, Neural and Dopaminergic Contributions to Novelty Driven Choice Behavior 6:30–7:00 pm Matt Nassar, “Dissociating information value from information quantity 9 3.

Dynamic compression and expansion in a classifying recurrent network Matthew Farrell1-2, Stefano Recanatesi1, Guillaume Lajoie3-4, and Eric Shea-Brown1-2 1Computational Neuroscience Center, University of Washington 2Department of Applied Mathematics, University of Washington 3Mila|Qu´ebec AI Institute 4Dept. of Mathematics and Statistics, Universit´ede Montr´eal Abstract Recordings of neural circuits in the brain reveal extraordinary dynamical richness and high variability. At the same time, dimensionality reduction techniques generally uncover low- dimensional structures underlying these dynamics when tasks are performed. In general, it is still an open question what determines the dimensionality of activity in neural circuits, and what the functional role of this dimensionality in task learning is. In this work we probe these issues using a recurrent artificial neural network (RNN) model trained by stochastic gradient descent to discriminate inputs. The RNN family of models has recently shown promise in reveal- ing principles behind brain function. Through simulations and mathematical analysis, we show how the dimensionality of RNN activity depends on the task parameters and evolves over time and over stages of learning. We find that common solutions produced by the network naturally compress dimensionality, while variability-inducing chaos can expand it. We show how chaotic networks balance these two factors to solve the discrimination task with high accuracy and good generalization properties.

  • Predictive Coding in Balanced Neural Networks with Noise, Chaos and Delays
    Predictive coding in balanced neural networks with noise, chaos and delays Jonathan Kadmon Jonathan Timcheck Surya Ganguli Department of Applied Physics Department of Physics Department of Applied Physics Stanford University,CA Stanford University,CA Stanford University, CA [email protected] Abstract Biological neural networks face a formidable task: performing reliable compu- tations in the face of intrinsic stochasticity in individual neurons, imprecisely specified synaptic connectivity, and nonnegligible delays in synaptic transmission. A common approach to combatting such biological heterogeneity involves aver- aging over large redundantp networks of N neurons resulting in coding errors that decrease classically as 1= N. Recent work demonstrated a novel mechanism whereby recurrent spiking networks could efficiently encode dynamic stimuli, achieving a superclassical scaling in which coding errors decrease as 1=N. This specific mechanism involved two key ideas: predictive coding, and a tight balance, or cancellation between strong feedforward inputs and strong recurrent feedback. However, the theoretical principles governing the efficacy of balanced predictive coding and its robustness to noise, synaptic weight heterogeneity and communica- tion delays remain poorly understood. To discover such principles, we introduce an analytically tractable model of balanced predictive coding, in which the de- gree of balance and the degree of weight disorder can be dissociated unlike in previous balanced network models, and we develop a mean field theory of coding accuracy. Overall, our work provides and solves a general theoretical framework for dissecting the differential contributions neural noise, synaptic disorder, chaos, synaptic delays, and balance to the fidelity of predictive neural codes, reveals the fundamental role that balance plays in achieving superclassical scaling, and unifies previously disparate models in theoretical neuroscience.

However, the neural mechanism by the neural mechanisms behind individual tasks. which multiple tasks are accomplished within the same system is largely unclear.

    Universality and individuality in neural dynamics across large populations of recurrent networks Niru Maheswaranathan∗ Alex H. Williams∗ Matthew D. Golub Google Brain, Google Inc. Stanford University Stanford University Mountain View, CA Stanford, CA Stanford, CA [email protected] [email protected] [email protected] Surya Ganguli David Sussilloy Stanford University and Google Brain Google Brain, Google Inc. Stanford, CA and Mountain View, CA Mountain View, CA [email protected] [email protected] Abstract Task-based modeling with recurrent neural networks (RNNs) has emerged as a popular way to infer the computational function of different brain regions. These models are quantitatively assessed by comparing the low-dimensional neural rep- resentations of the model with the brain, for example using canonical correlation analysis (CCA). However, the nature of the detailed neurobiological inferences one can draw from such efforts remains elusive. For example, to what extent does training neural networks to solve common tasks uniquely determine the network dynamics, independent of modeling architectural choices? Or alternatively, are the learned dynamics highly sensitive to different model choices? Knowing the answer to these questions has strong implications for whether and how we should use task-based RNN modeling to understand brain dynamics. To address these foundational questions, we study populations of thousands of networks, with com- monly used RNN architectures, trained to solve neuroscientifically motivated tasks and characterize

N., Chen, R., Benster, T., Mourrain, P., Levoy, M., Karl Deisseroth* Kanaka Rajan* ​ *co-corresponding authors ​ Abstract Text: Based on imaging in over 10,000 neurons across more than 15 regions imaged simultaneously in larval zebrafish during a novel behavioral challenge paradigm, we built and analyzed a recurrent neural network model constrained by the data from the outset. The model focused on activity in the habenula and raphe, identifying a significant and specific change in intra-habenular connectivity as a result of the behavioral challenge paradigm. We are extending this work to a whole-brain level multi-region recurrent neural network model and its accompanying theory of brain-wide control of adaptive to maladaptive state transitions. We consider the complex multi-dimensional interactions in the whole brain and relate them causally to behavior of the intact organism. We therefore present a new, more robust, scalable class of circuit models – multi-region neural network models, with support from a BRAIN Initiative/NIH Theories, Models, and Methods grant (1R01EB028166-01). These models are constrained by experimental data at two levels simultaneously: (a) large-scale neural dynamics – cellular resolution activity imaged from all 15 larval zebrafish brain regions – and (b) the behavior of the organism – tail movements tracked real-time in a range of behavioral states.
