Most current algorithms only work well in special conditions , because of the abnormity of signals in the real world . now , the research in the ica arises much passion and the ica has brought about many applications . the primary results the writer has got are as the following : after a whiting process , it is a key to find an orthogonal matrix to throw away the high - order redundant information between components 由于現(xiàn)實生活中信號十分不規(guī)則,目前提出的算法大多只能針對某類信號分離,鑒于目前在ica方面極大的研究熱情和強大的背景支持,作者對ica離線算法做了一定研究,主要內容和工作包括如下: ica問題經(jīng)過白化處理后,尋找去除高階相關的正交矩陣成為問題關鍵,而正交矩陣具有特殊的空間結構,組成它的每個列向量可視作rn中單位超球表面上一點,當這些點彼此垂直時,整體就組成一個正交矩陣。
The balanced multiwavelet was studied . for low - pass matrix filter p ( ) , the orthogonal matrix r was selected to ensure the constant signal as a characteristic signal of balanced low - pass matrix filter rtp ( ) r , the corresponding balanced high - pass matrix filter is q ( ) r or rtq ( ) ) r which maintain the orthogonality and symmetry or orthogonality only respectively . as an application , the optfr - multiwavelet constructed by jiang was balanced and applied to image denoising and fusion 研究了多小波的平衡處理,對低通濾波器p ( )一般選擇平衡器為正交矩陣r ,使得常數(shù)信號成為平衡后的低通濾波器r ~ tp ( ) r的特征信號,若要保持矩陣濾波器的正交性和對稱性,可選擇平衡后的高通濾波器為q ( ) r ;若只保持多小波的正交性,可選擇高通濾波器為r ~ tq ( ) r 。
To solve the problem , a kind of multi - ontology analysis framework consisted of orthogonal matrix made up of multi - dimensional ontology model and temporal model is re - searched ; and then multi - dimension knowledge warehouse based on xml topic maps is constructed , which is developed to implement the accurate and efficient storing and retrieving for knowledge of semantic level 針對這個問題,研究了通過多維本體模型和時域模型的正交矩陣構建的多本體分析框架,并以此為基礎,構建了基于xml主題地圖技術的多維知識倉庫,實現(xiàn)了高效準確的語義級知識的存儲和檢索。
