約化矩陣元 的英文怎麼說
中文拼音 [yāohuàjǔzhènyuán]
約化矩陣元
英文
reduced matrix element-
We deduce easily the coherent term of quantum dynamical model ( the off - diagonal of reduced density matrix ) by improving the nature of displace operator and the nature of coherent states. then, the interaction is energies of a two - photon mechanism and the usual one - photon or liner driving mechanism. we deduce the coherent term by improving the nature of squeezing operators, displace operators and canonical transformation
其一，僅有阻尼相互作用和勢能相互作用，此時利用位移算符的性質和相干態的性質很方便地推導了量子動力學模型的相干項（約化密度矩陣的非對角元） ；其二，考慮的是既有單光子相互作用又有雙光子相互作用，這時利用相干態、壓縮算符及正則變換等的性質推導出相干項。One is based on the discriminated matrics, the other is based on ga. we use many new ways to make the algorithms more effective, such as reducing dimension and sparsiting elements of the discriminated matrics, effectively selecting elements of the positive examples set and the counter examples set for the jointing - spreading matrics, using a new selecting operator, and so on
其次，實現了基於粗集理論的屬性約簡方法? ?基於可分辨矩陣的屬性約簡法和基於遺傳演算法的屬性約簡法，並通過降維、稀疏化、正例集和反例集的有效選取、新的選擇運算元等方法對原演算法進行了改進。3 ) give the reduct algorithm and improved algorithm based on discernibility matrices. 4 ) give the algorithm of rules. 5 ) in this thesis, by using rs theory in the synthesis of combinational logic function, we can get minimal expression of logic function ; if by using rs theory in the rough control of boiler, we can get rough control rules
對於前人提出的差別矩陣和差別函數的概念和定義，將其應用於信息系統中，用差別函數得到了最小約簡，然後，通過研究差別矩陣和差別函數的構造過程，提出了對差別矩陣降階和消元的策略，實例證明是有效的，起到了化簡差別矩陣和差別函數的目的； 4The existing algorithms usually add damping term of the form. xlog. x into their objective function in order to control matching matrix ' s entropy. the shortcoming is that the two - way constraints need to be enforced by using sinkhorn method
這類演算法為了控制匹配矩陣元素的熵，通常在目標函數中加入xlogx形式的阻尼項，其缺點是需要用sinkhorn交替歸一化方法或其它方法使匹配矩陣滿足雙向的行列約束。分享友人
