Reinforcement Learning for Central Pattern Generation in Dynamical Recurrent Neural Networks
Lifetime learning, or the change (or acquisition) of behaviors during a lifetime, based on experience, is a hallmark of living organisms. Multiple mechanisms may be involved, but biological neural circuits have repeatedly demonstrated a vital role in the learning process. These neural circuits are recurrent, dynamic, and nonlinear and models of neural circuits employed in neuroscience and neuroethology tend to involve, accordingly, continuous-time, nonlinear, and recurrently interconnected components. Currently, the main approach for finding configurations of dynamical recurrent neural networks that demonstrate behaviors of interest is using stochastic search techniques, such as evolutionary algorithms. In an evolutionary algorithm, these dynamic recurrent neural networks are evolved to perform the behavior over multiple generations, through selection, inheritance, and mutation, across a population of solutions. Although, these systems can be evolved to exhibit lifetime learning behavior, there are no explicit rules built into these dynamic recurrent neural networks that facilitate learning during their lifetime (e.g. reward signals). In this work, we examine a biologically plausible lifetime learning mechanism for dynamical recurrent neural networks. We focus on a recently proposed reinforcement learning mechanism inspired by neuromodulatory reward signals and ongoing fluctuations in synaptic strengths. Specifically, we extend one of the best-studied and most-commonly used dynamic recurrent neural networks to incorporate the reinforcement learning mechanism. First, we demonstrate that this extended dynamical system (model and learning mechanism) can autonomously learn to perform a central pattern generation task. Second, we compare the robustness and efficiency of the reinforcement learning rules in relation to two baseline models, a random walk and a hill-climbing walk through parameter space. Third, we systematically study the effect of the different meta-parameters of the learning mechanism on the behavioral learning performance. Finally, we report on preliminary results exploring the generality and scalability of this learning mechanism for dynamical neural networks as well as directions for future work.
Journal Article
The world of Gloria Vanderbilt
Gloria Vanderbilt is many things: an heiress, a painter, a muse, a designer, a model, a writer, an entrepreneur, an actor, a socialite, a survivor, an icon. She brought the Vanderbilt name out of the Gilded Age and into the Digital Age, reinventing herself over and over along the way. Hers is a story of charisma, glamour, and heartbreaking loss, told here by Wendy Goodman, who had intimate access to Vanderbilt for this book. The illustrations include portraits of Vanderbilt and her extraordinary homes, filled with original and influential decorating ideas, by such photographic legends as Richard Avedon, Louise Dahl-Wolfe, Inge Morath, Horst P. Horst, Francesco Scavullo, and Annie Leibovitz. Vanderbilt's son, Anderson Cooper, contributes a foreword.--From publisher description.

The World War I book
Combining authoritative, exciting text and bold images, The World War I Book explores the historical background of the war, its causes, all of the key events across the major theatres of conflict, and its aftermath. Using the original, graphic-led approach of the series, entries profile more than 90 of the key events during and surrounding the conflict -- from the growing tensions between Europe's major powers to the assassination of Archduke Franz Ferdinand, the German invasion of Belgium, the endless slaughter in the trenches, the American entry into the war, the Russian Revolution, the Armistice, and the creation of the League of Nations.
