 | Mathews, V. John | Neural decoding using a nonlinear generative model for brain-computer interface | Kalman filters have been used to decode neural signals and estimate hand kinematics in many studies. However, most prior work assumes a linear system model, an assumption that is almost certainly violated by neural systems. In this paper, we show that adding nonlinearities to the decoding algorithm ... | 2014-01-01 | |
