以概念學習模式解析中西坐椅設計風格辨識的規則

A Study on the Style Discrimination between Chinese and Western Chairs by Using the D-MAX Concept Learning Model

本研究以人工智慧概念學習之D-MAX（MAXimzing the Difference between classes，最大差異法）決策樹模式的操作，透過關連“及／或＂（conjunction and / or disjunction） 的分類法則與最佳化技術的運用，針對以25張包括有玫瑰椅、間椅、太師椅與官帽椅之中國風格坐椅為正示例，及25張包括有Baroque、Queen Anne、Hepplewhite、Chippendale 等風格的西方風格坐椅為負示例，推導出中、西坐椅設計風格分類的規則，並藉由正確率與包含率的評估，討論在這些規則下，所顯示中間坐椅設計風格的造形語彙及其形成，期望能藉此建構完整的風格造形特徵與形式之視覺情報庫，以作為輔助產品設計的工具。

In this study, by using the D-MAX （MAXimzing the Difference between classes） concept learning model, a classification tree was deducted from 25 Chinese style chairs as positive examples, including Rose chairs, Loop chairs, Tai-Shih chairs, Official-hat chairs, and 25 Western style chairs as negative examples, including chairs of Baroque style, Queen Anne style, Hepplewhite style, Chippendale style. The discrimination rules between Chinese and Western style chairs were summarized from this classification tree and were evaluated for the relative significance through accuracy and coverage. The form features under each rules then were discussed in detail. Finally, the form language in constituting Chinese and Western style chairs was concluded. Based on this form language and results of some further studies, a visual data bank for assisting designers to create products with Chinese or Western style is expected to be developed gradually.
