Introduction The EKF has been applied extensively to the field of non-linear estimation. General applicationareasmaybe divided into state-estimation and machine learning. We further di-vide machine learning into parameter estimation and dual estimation. The framework for these areas are briefly re-viewed next. State-estimation

nonlinear state estimation problem. For example, the aug-mented state approach turns joint estimation of an uncertain linear system with afne parameter dependencies into a bilinear state estimation problem. Following this path, it is typically difcult to provide convergence results [6]. Joint parameter and state estimation schemes that do provide

Dynamic state estimation is to predict the state vector one time step ahead and has the potential to foresee potential contingencies and security risks [9], [10]. Unlike the traditional state estimation and dynamic state estimation that focus on estimating relatively stationary state vectors, in this ARX dynamic response estimation, we

into two approaches: depth and color images. Besides, pose estimation can be divided into multi-person pose estimation and single-person pose estimation. The difficulty of multi-person pose estimation is greater than that of single. In addition, based on the different tasks, it can be divided into two directions: 2D and 3D. 2D pose estimation

simultaneous state estimation and time-varying parameter estimation of a continuous-time nonlinear system. Using a set-based adaptive estimation, the estimates for the parameters and the state variables are updated to guarantee convergence. The algo-rithm is proposed to detect a fault in the system triggered by a drastic change in the

rameters. The parameter estimation algorithm entails a state estimation procedure that is carried out by non-Gaussian filters. The probability density function of the system state is nearly Gaussian even for strongly nonlinear models when the measure-ments are dense. The Extended Kalman filter can then be used for state estimation.

lenges in 2D human pose estimation has been estimating poses under self-occlusions. Indeed, reasoning about occlu-sions has been one of the underlying motivations for work-ing in a 3D coordinate frame rather than 2D. But one of our salient conclusions is that state-of-the-art methods do a surprisingly good job of 2D pose estimation even under oc-

The position estimation is carried out differently for low and high speeds. The low speed position estimation is done by exploiting magnetic nonlinearities in the electromagnetic structure (saturation, saliency, slot harmonics, etc). The back emf is utilized for the position estimation at high speed.
