  1. This idea arose to explain a puzzling fact about dark matter : although it clumps on the vastest scales, creating bodies such as galaxy clusters, it seems to resist clumping on smaller scales

    這個想法正足以解釋關于暗物質的一些謎題：盡管暗物質大規模簇擁在一起、創生出大如星系團的物體，它們卻似乎不願聚集成較小的物體。
  2. However, there have still some unresolved problems : first, how to determine the number and size of the clusters automatically during the clustering process. second, how to utilize the " local " ridge regression method which including multiple regularization parameters in learning rbf network. third, those clusters in irregular form ca n ' t represented by radial basis function, thus we must find some other basis functions that can describe the irregular form

    但是仍然存在幾個問題尚待解決：首先，聚類時怎樣自動確定簇的個數和半徑；其次，如何利用含有多個正規化參數的局部嶺回歸方法進行rbf網路學習；第三，如果簇的形狀是不規則的，則它很難用徑向基函數來描述，因此需要研究其它能代表不規則形狀的簇的基函數。
  3. Define a radial basis function ( rbf ) at center of each cluster and learning a two - layer neural network which consists of these rbfs, simultaneously, for the purpose of avoiding over - fitting, we make use of ridge regression method, which adding a weight penalty term including a appropriate regularization parameter on the cost function and then lead to a more smooth function

    為每一個簇的中心定義相應的徑向基函數（ radialbasisfunction ， rbf ） ，再對這些徑向基函數構成的兩層神經網路進行訓練，同時，為了避免產生過度擬合現象，本文採用了嶺回歸技術，即在代價函數中加入一個包含適當正規化參數的權值懲罰項，從而保證網路輸出函數具有一定的平滑度。
