權逆陣 的英文怎麼說
中文拼音 [quánnìzhèn]
權逆陣
英文
inverse of weight matrix-
For a general linear model ( input matrix is deterministic ), under a certain conditions on variance matrix invertibility, the two estimates can be identical provided that they have the same priori information on the parameter under estimation. even if the above information is unknown only for the optimally weighted ls estimate, the sufficient condition and necessary condition, under which the two estimates are identical, is derived. more significantly, we know how to design input of the linear system to make the performance of the optimally weighted ls estimation identical to that of the linear minimum variance estimation in case of being lack of prior information
在一般線性模型（即輸入矩陣為確定性）下，當兩種估計都利用有關被估參數的先驗信息時，二者在方差陣可逆的一定條件下可達到一致；當最優加權最小二乘估計不利用此先驗信息時，存在二者一致的充分條件和必要條件，進而找到一種設計輸入矩陣的方法，使得在先驗信息缺乏的條件下，仍可利用最優加權最小二乘估計達到與線性最小方差估計一樣優越的估計性能。On existence of weighted group inverses of rectangular matrices
關于長方矩陣的加權群逆的存在性Then we give the necessary and sufficient condition under which the optimally weighted ls estimate is identical to thu conditional mean of the parameter given input and observation, i. e., the optimally weighted ls estimate could be optimal nonlinear estimate in the minimum variance sense
在方差陣可逆的條件下，我們發現最優加權最小二乘估計優于線性最小方差估計，進而得到了其與最小方差估計（即條件均值估計）等價的充要條件。Since the filtering vector is needed in qrd - rls and qrd - brls, the parallelism of qr decomposing will be impeded slightly. the inverse qr decomposion ( iqrd ) scheme for brls algorithm is proposed in this dissertation to enhance the parallelism, the systolic array structure for iqrd is proposed to calculate the algorithm in parallel
鑒于碼輔助最優濾波需要求解濾波權值矢量，此時qr分解的計算并行性不如逆正交三角分解（ iqrd ） ，本文提出了基於iqr分解的brls演算法，給出了iqrd - rls / brls的脈動陣列并行計算結構。In 1980 cline and greville gave the definition of the w - weighted drazin inverse which is the extension of drazin inverse. from then on many people studied the w - weighted drazin inverse in different fields
