Not all functions are linear. There are many non-linear functions which can't be modeled by a single straight line. However, locally, all the non-linear functions can be modeled by the linear ...

When estimating derivatives of regression functions from noisy data, a number of additional problems arise compared with the estimation of the regression function itself. Linear methods, such as ...

This article aims at non-asymptotically and robustly estimating the fractional integral and derivative of the state for a class of integer order linear systems in noisy environment using the ...
