In the last decade, there exist two active lines on the investigation of nonlinear time series. one is the autoregressive conditional heteroscedasticity ( arch ) model, the another is the nonstationary ( unit root ) time series model
對非線性時間序列的研究，近幾十年來，有兩條研究路線非常活躍，其一是自回歸條件異方差（ arch ）模型，其二是非平穩（單位根）時間序列模型。 -
As far as the nonstationarity during the long period operation of machinery was concerned, the application of adaptive linear element ( adaline ) neural network to prediction of nonstationary time series was studied. the relationship between adaline and auto regressive ( ar ) model was analyzed, and the method to determine the number of input neurons in adaline prediction model according to bic criteria was presented. the effect of the adaptive learning rate on prediction was also analyzed
針對生產實踐中設備運行的非平穩性，基於動態預測思想，研究了非平穩時間序列的自適應線性單元（ adaline ）神經網路預測，討論了adaline和自回歸（ ar ）模型之間的關系，提出根據ar模型定階方法確定adaline預測模型的輸入神經元數目，分析了自適應學習率對預測性能的影響，為機械設備狀態預測提供了一種方法。 -
