資料視覺化分析對於資料處理、探索資料結構、辨識趨勢及叢聚、發現局部模式（pattern or subgroup）、評估模型分析輸出（output）與呈現分析結果都相當有幫助，對於探索性數據分析（exploratory data analysis）、網絡分析（network analysis）及機器學習等大數據分析更是不可或缺。然而資料科學成功的基礎為特徵工程（Feature Engineering），它是資料科學流程中最耗費時間的步驟，包含準備階段、生成階段、轉換階段、建模階段及操作階段等流程。
本課程主要目標為使用SAS及R軟體與實際調查資料，來展現資料視覺化分析能展現資料中的哪些資訊。透過實際操作來增加具體設計、分析及詮釋統計圖像的經驗，來有效率地了解資料視覺化分析與機器學習。
Data visual analysis is very helpful for data processing, exploring data structure, identifying trends and clusters, discovering local patterns (pattern or subgroup), evaluating model analysis output (output) and presenting analysis results. It is also very helpful for exploratory data analysis (exploratory). Big data analysis such as data analysis, network analysis and machine learning are even more indispensable. However, the basis for the success of data science is Feature Engineering, which is the most time-consuming step in the data science process, including the preparation phase, generation phase, conversion phase, modeling phase and operation phase.
The main goal of this course is to use SAS and R software and actual survey data to show what information in the data can be revealed by visual data analysis. Through practical operations, you can gain experience in designing, analyzing, and interpreting statistical images to effectively understand data visualization analysis and machine learning.
