Unformatted text preview: Outline of the Lecture Outline of the Lecture Linear System Identification Linear System Identification Backbox Models Impulse Response Reverse Backbox Models Impulse Response Reverse Correlation Correlation Reverse Correlation Can Reverse Correlation Can Determine a Neural Linear Determine a Neural Linear system’s Impulse Response system’s Impulse Response A recurrent network is a feedforward network with a recurrent synaptic weight matrix. Some neuronal tissues are so massive and complex that network analysis is not too useful. Perception is a constructive process that depends on both the stimulus information and the mental structure of the perceiver. Even when network analysis is not useful, we can still comprehen d aspects of brain functions with models that are more generic. David Marr’s three levels of understanding computations. In a blackbox model, we try to describe a system well enough to predict its responses without knowing what is inside the system. If the black box is linear, then we can describe the system fully with the impulse response, as any stimulus is a sum of impulses. The impulse response D(t) is...
