  4. Neural networks are used more frequently in lossy data coding than in general lossless data coding, because standard neural networks must be trained off - line and they are too slow to be practical. in this thesis, statistical language model based on maximum entropy and neural networks are discussed particularly. then, an arithmetic coding algorithm based on maximum entropy and neural networks are proposed in this thesis

    傳統的人工神經網路數據編碼演算法需要離線訓練且編碼速度慢，因此通常多用於專用有損編碼領域如聲音、圖像編碼等，在無損數據編碼領域應用較少，針對這種現狀，本文詳細地研究了最大熵統計語言模型和神經網路演算法各自的特點，在此基礎上提出了一種基於神經網路和最大熵原理的算術編碼方法，這是一種自適應的可在線學習的演算法，並具有精簡的網路結構。

    在系統網路體系結構（ sna ）中使用的一種數據轉換法，即把兩個字元裝配在一個位元組之中，這樣就可以利用在允許使用的256個字元中只使用了其中的一個子集這一點，來把最常發送的字元進行壓縮。
  8. Data mining ( dm ) aims at drawing implied and useful information / knowledge from massive incomplete, noisy, blurry, and stochastic real data ; while neural network is a frequently used tool for dm

  13. However, the second technology has the following disadvantages : first, data paging and tmrm generating are integrated into one modulate, next, data structures they used are very complicated and large, in addition, the work of data preprocessing is very heavy and frequently data paging need the server with high performance, at last this paging method is very difficult for implementation. as for the first technology, an important advantage of it is that the data paging and tmrm generating are not interdependent, so it will be more e asily applied in practice than the second one. as an implementation of the first technology, lindstrom introduced a method which uses quadtree and triangle binary tree to organize terrain data and adopt multithread mechanism to realize the data process

    而第一種流式處理技術盡管一次調入的數據量稍大，但其數據調度與多解析度模型的生成在功能上是相互獨立的，如果處理得當更容易在實際工程中得到成功的應用，對於它的實現， lindstrom提出了利用四叉樹及三角形二叉樹進行地形數據組織並利用多線程機制進行數據調度與簡化的流式處理方法，但該方法的缺點是：其數據結構依賴于地形的物理分割，因此數據結構龐大；多解析度模型生成的計算量也依賴於物理分割的粒度，即物理分割粒度較粗時，數據范圍增大，計算量會急劇增加；該方法不能實現模型的增量生成。
