中文摘要 |
在本論文中,是以貝式網路的形式從有時序狀態轉換的工作流程紀錄中去發掘有用的知識。貝式網路是一種利用圖形來表現的模式,此圖形會包含每個相關連的變數的機率值,並且可以很簡單的去合併一個新的資料到貝式網路中,以維持貝式網路的資料始終是最新的。貝式網路的用途很多,它可以用來做預測、溝通、訓練及提供更多的選擇來做更好的決策。在本論文中,我們將會利用我們所提出來的分法應用在血液透析上,透過此方法來表達醫護人員的醫療處理與病患生理狀態轉換的關係,進而去發掘血液透析臨床路徑上的特徵,藉由這些特徵能提供醫護人員去預測病人可能的血液透析臨床路徑,以及血液透析機參數設定的參考。在未來,希望藉由此研究的結果,再加上實證上的研究,使得醫療人員在血液透析的知識管理上能有一個良好的互動結果。 |
Abstract |
In this thesis, we discover knowledge from workflow logs with temporal-state transitions in the form of Bayesian networks. Bayesian network is a graphical model that encodes probabilistic relationships among variables of interest, and easily incorporates with new instances to maintain rules up to date. The Bayesian networks can predict, communicate, train, and offer more alternatives to make better decisions. We demonstrate the proposed method in representing the causal relationships between medical treatments and transitions of patient’s physiological states in the Hemodialysis process. The discovery of clinical pathway patterns of Hemodialysis can be used for predicting possible paths for an admitted patient, and facilitating medical professionals to control the Hemodialysis machines during the Hemodialysis process. The reciprocal knowledge management can be extended from the results in future research. |
