Abstract(J)近年、衝突CAEを活用したロバスト性評価や最適化などの大量計算を伴う開発が増えている。またAI技術を応用した開発事例も増加しているがAIの推論結果を実務で有効活用する上ではその解釈性も重要となる。本講演ではCAE技術者の解釈性を考慮した、機械学習による衝突性能予測および車体構造推定の試みを紹介する。

Abstract(E)A number of calculations for Crash CAE is required to robustness evaluation or optimization study in recent vehicle development. And also, a few implementations of AI technology utilizing those results have been reported. However, in order to apply inference result of AI for development, that interpretability is also important. Therefore we approach to crash performance prediction and estimation of parameters of body structure by data mining methodology considering the interpretability of a skilled CAE engineers.

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.
