Structurally Recursive Method algorithm

The Structurally Recursive Method is then expanded, and a second, non-recursive algorithm fw the manipulator inertia matrix is derived from it A finite summation, which is a function of individual link inertia matrices and columns of the propriate Jacobian matrices, is defined fw each element of the joint space inertia matrix in the Inertia Projection Method. Further manipulation of this expression and application of the composite-rigid-body inertia concept [42] are used to obtain two additional algwithms, the Modified Composite-Rigid-Body Method and the Spatial Composite-Rigid-Body Method, also in the fourth section. These algorithms do make use of recursive expressions and are more computationally efficient. 

Four algorithms for computing the joint space inertia matrix of a manipulator are presented in this section. We begin with the most physically intuitive algorithm the Structurally Recursive Method. Development of the remaining three methods, namely, the Inertia Projection Method, the Modified Composite-Rigid-Body Method, arid the Spatial Composite-Rigid-Body Method, follows directly from the results of this tot intuitive derivation. 

In the next analysis, we will examine the components of successive inotia matrices as defined by the algorithm given in Table 3.1. First, the expansion of the equations for the Structurally Recursive Method leads to an exjnession for H,j, the Tii X itj submatrix of H, in the form of a summation. Its terms involve projections of individual link inertias onto the preceding joint axis vectors, which... 

A cascade method was proposed using recursive partitioning and descriptors generated with a program called Algorithm Builder were used with a 800-compound training set [35]. Their predictions are 2-class models with Fs less than and more than 30%, respectively. As parameters, they use a combination of solubility, pifractions ionized, human permeability, P-gp substrate specificity, physicochemical properties, and various structural descriptors. This is an attempt to model the components of bioavailability and then to integrate them into an overall prediction (see further in Section 16.4).

The Decision tree method is widely used for classification and regression. A decision tree is a flow-chart-like tree structure, where each internal node denotes a test on an attribute, each branch represents an outcome of the test, and leaf nodes represent classes or class distributions. In order to classify an unknown sample, the attribute values of the sample are tested according to the decision tree starting from the root until one of the leaves. To build decision trees, a data mining algorithm recursively inspects the available data set to find decisions that optimally split the data into distinguished subsets. An important property of this technique is that its functioning is easily understood. 

The point of departure for the constructive method was the consideration of a passive control structure in the light of a suitable definition of finite-time motion stability. Then, the related dynamical inverse yielded the controller and a recursive algorithm to design the nominal batch motion. The underlying solvability conditions were identifying. The combination of the controller with an observer with a compatible structure yielded the design of the output feedback tracking controller. 

So why not immediately use the Synthesis Method The reason is that both methods tackle different classes of problems. The MSG Method and the Synthesis Method are a joint answer to the same overall problem how to infer, from a finite set of general examples of an unknown relation that is however known to feature a given dataflow pattern between its parameters, a logic algorithm that is correct wrt a natural extension of the given examples. The MSG Method is the base case of the answer, because it doesn t look for recursion, and the Synthesis Method is the structure case of the answer, because it does look for recursion. 

In section Structural Parametric Identification by Extended Kalman Filter, online structural parametric identification using the EKF will be briefly reviewed. In section Online Identification of Noise Parameters, an online identification algorithm for the noise parameters in the EKF is introduced. Then, in section Outlier-Resistant Extended Kalman Filter, an online outlier detection algorithm is presented, and it is embedded into the EKF. This algorithm allows for robust structural identification in the presence of possible outliers. In section Online Bayesian Model Class Selection, a recursive Bayesian model class section method is presented for non-parametric identification problems.
