為了解決Us Stock real-time c 的問題，作者Fan, Jianqing/ Yao, Qiwei 這樣論述：
Amongmanyexcitingdevelopmentsinstatisticsoverthelasttwodecades, nonlineartimeseriesanddata-analyticnonparametricmethodshavegreatly advanced along seemingly unrelated paths. In spite of the fact that the - plication of nonparametric techniques in time series can be traced back to the 1940s at least,
there still exists healthy and justi?ed skepticism about the capability of nonparametric methods in time series analysis. As - thusiastic explorers of the modern nonparametric toolkit, we feel obliged to assemble together in one place the newly developed relevant techniques. Theaimofthisbookistoadvo
catethosemodernnonparametrictechniques that have proven useful for analyzing real time series data, and to provoke further research in both methodology and theory for nonparametric time series analysis. Modern computers and the information age bring us opportunities with challenges. Technological in
ventions have led to the explosion in data c- lection (e.g., daily grocery sales, stock market trading, microarray data). The Internet makes big data warehouses readily accessible. Although cl- sic parametric models, which postulate global structures for underlying systems, are still very useful, la
rge data sets prompt the search for more re?nedstructures, whichleadstobetterunderstandingandapproximations of the real world. Beyond postulated parametric models, there are in?nite other possibilities. Nonparametric techniques provide useful exploratory tools for this venture, including the suggest
ion of new parametric models and the validation of existing ones
機器學習對外匯報酬之預測
為了解決Us Stock real-time c 的問題，作者蔡伯甯 這樣論述：
本研究首先使用機器學習的模型，比較主成份分析（PCA）與自動編碼器（Autoencoder）兩種方式做降維後的資料擬合之結果，並且以測試集的R^2衡量表現，結果顯示，經過自動編碼器預訓練後的資料能更大幅度的提升模型性能。下一步，使用前面訓練好的模型作為弱學習器，以簡單平均的方式做集成，比較三個弱學習器與集成後的預測表現，再以模型預測結果作為買賣訊號來建構外匯投資組合，同時，加入利差策略與動量策略作為比較基準，觀察投資組合的績效表現，根據實驗結果，集成後的投組明顯優於個別機器學習模型，而機器學習模型又優於傳統策略。
探索智慧物聯網研究：文獻計量分析與主題建模方法
為了解決Us Stock real-time c 的問題，作者吳慶福 這樣論述：
為清楚勾勒出智慧物聯網研究發展樣貌，本研究探索Web of Science 1975年至2021年5,436篇「智慧物聯網」為主題的文獻。經文獻計量分析發現：(1)文獻出版年份為2012-2021年，2012-2016年為生長期，2017-2021年為發展期；(2)《IEEE Internet of Things Journal》是AIoT議題最具影響力的期刊；(3)中國大陸、美國、印度發表篇數分居前3名，臺灣位居第9名；(4) AIoT文獻可區分「工業4.0管理、智慧城市治理及未來挑戰」等7個集群。以潛在狄利克雷分佈(Latent Dirichlet allocation, LDA)發現
文獻聚焦在「智慧醫療」等6個主題。綜觀文獻計量分析關鍵字共現聚類，以及LDA潛在主題重點，均關注智慧醫療、工業4.0、資通安全及隱私保護的議題。就AIoT國防應用，提列「智慧物聯網多元軍事應用」等2項建議，並對國軍人事等8個業務工作面向，提供「人才招募客服聊天機器人」等21項AIoT可行方案，藉由導入智慧物聯網，提升智慧國防戰力，帶動全民支持及參與國防。透過上述研究發現，以及文獻計量分析、LDA主題建模的分析過程，可有效探討智慧物聯網研究，迅速掌握領域研究樣貌，並且提供後續相關研究納為參考與指引。
