(A) About Me

I am currently a research scientist at the RIKEN Brain Science Institute (BSI) Laboratory for Neural Computation and Adaptation. Under Taro Toyoizumi's mentorship, I study the principles of information processing in the brain with a focus on learning  in the neural circuitry underling adaptive behavior and higher-level cognitive functions. Specifically, I am studying efficient learning algorithms for chaotic recurrent neural networks. Neural network in the brain show learning and adaptation in the presence of persistent activity levels that have many signature of chaos. Success of deep learning in feedforward and recurrent network has raised question about the possibility that the brain maybe employing similar techniques, which once thought implausible. Current gradient-based approaches however cannot be used for learning chaotic network with on going activity largely due to dynamics of gradient flow in chaotic networks. My research focus is designing efficient algorithms that can train recurrent neural network in chaotic regime. 







Previously

I  was a PhD student in computer science at UNM. I completed my dual M.S. degrees in computer science and systems science at Portland State University. My main focus of study has been Artificial Intelligence (AI) and Complex Adaptive Systems (CAS), in particular modeling unconventional computing paradigms. The topic of my M.S. thesis was
 application of machine learning, reconstructability analysis, Artificial Neural Networks (ANN), and Evolutionary Algorithms (EA) in the study of adaptive behavior in complex systems in the context of Alan Turing's "unorganized machine" and Random Boolean Networks (RBN). Recently, my focus has been on the theory and application of computing with excitable dynamics (reservoir computing and echo state network). I developed a closed-form training method for the reservoir that does not require the simulation of the reservoir on an input signal. For my PhD I will demonstrate the application of this method on signal processing using DNA (for biomedical applications), and self-assembled nanowires (for neuromorphic applications). My latest research present exciting opportunities with the merger of reservoir computing and deep learning for temporal tasks.
