Abstract(J)自動車空力開発において、計算コスト削減のため深層生成AIを活用し空力性能評価を迅速に行う手法が検討されている。しかし、生成AIは解釈性が低いためモデルや適応範囲の妥当性推定が課題である。本稿では形状生成AIの解釈性を向上させる手法を活用し,解釈性に基づく自動車空力開発手法の検討を報告する.

Abstract(E)Deep generative models have demonstrated potential in accelerating aerodynamic design via reduced simulation cost in automotive development. However, their practical adoption is hindered by limited interpretability; this challenge obscures decision-making process and complicates integration into automotive development workflows. Here, we report the application of interpretable generative model architecture and attribute visualization technique, offering a pathway towards more interpretable and actionable AI-integrated automotive development.

How to use the search box

You can enter up to 5 search conditions. The number of search boxes can be increased or decreased with the "+" and "-" buttons on the right.
If you enter multiple words separated by spaces in one search box, the data that "contains all" of the entered words will be searched (AND search).
Example) X (space) Y → "X and Y (including)"

How to use "AND" and "OR" pull-down

If "AND" is specified, the "contains both" data of the phrase entered in the previous and next search boxes will be searched. If you specify "OR", the data that "contains" any of the words entered in the search boxes before and after is searched.
Example) X AND Y → "X and Y (including)"  X OR Z → "X or Z (including)"
If AND and OR searches are mixed, OR search has priority.
Example) X AND Y OR Z → X AND (Y OR Z)
If AND search and multiple OR search are mixed, OR search has priority.
Example) W AND X OR Y OR Z → W AND (X OR Y OR Z)

How to use the search filters

Use the "search filters" when you want to narrow down the search results, such as when there are too many search results. If you check each item, the search results will be narrowed down to only the data that includes that item.
The number in "()" after each item is the number of data that includes that item.

Search tips

When searching by author name, enter the first and last name separated by a space, such as "Taro Jidosha".
