摘要: 論文提出將正則化神經(jīng)網(wǎng)絡(luò)與粗集理論相結(jié)合應(yīng)用于股票時(shí)間序列數(shù)據(jù)庫(kù)的數(shù)據(jù)挖掘.首先對(duì)時(shí)間序列數(shù)據(jù)庫(kù)進(jìn)行預(yù)處理,除去高頻干擾信號(hào),然后將股票時(shí)間序列數(shù)據(jù)按照收盤(pán)價(jià)的變化趨勢(shì)分割成一系列靜態(tài)模式,每種模式代表股票價(jià)格的一種行為趨勢(shì)(上漲或下跌),把決定各種模式的相關(guān)屬性組成一系列信息,形成一個(gè)適用于粗集方法的信息表.然后使用正則神經(jīng)網(wǎng)絡(luò)對(duì)信息表進(jìn)行學(xué)習(xí),用粗集理論從正則神經(jīng)網(wǎng)絡(luò)所存儲(chǔ)的知識(shí)中抽取規(guī)則,得到的規(guī)則可以用于預(yù)測(cè)時(shí)間序列在未來(lái)的行為。該方法融合了正則神經(jīng)網(wǎng)絡(luò)優(yōu)良的泛化性能和粗集理論的規(guī)則生成能力,實(shí)驗(yàn)表明,該方法預(yù)測(cè)效果比較準(zhǔn)確。Abstract: This paper presents a new method of stock market time series data mining. It combines regularized neural network with rough set. The process includes preprocessing of time series and data mining. The preprocessing cleans and filters time series. Then, the time series are partitionel into a series of static patterns, which is based on the trend (i.e., increasing or decreasing) of closing price. The most important predicting attributes identified from every model form an information table. The regularized neural network is used to learn and predict the data. Rough set can extract rule knowledge in the neural network, which can be used to predict the time series behavior in the future. This method combines the generalization faculty of regularized neural network and the rule reduction capability of rough set. The experimental results demonstrate the effectiveness of the algorithm.
