摘要： A formed member is provided which can be manufactured at a low cost, which has excellent dimensional accuracy, which has excellent axial crushing properties and three-point bending properties, which has excellent bending stiffness and torsional stiffness, and which is suitable for use in a component of an automobile. The formed member (20) has a reinforcing member (35) which is joined by a weld (40) provided on a ridge portion (28). It is manufactured by joining a flat sheet blank and a flat sheet reinforcing member (35) by a weld (40) and performing bending so that the weld (40) becomes a ridge portion (28).

摘要： The welding quality classification apparatus relating to the present invention is an apparatus, wherein a data point indicating feature information of a welded joint to be classified whose welding quality is unknown is mapped to a point in a mapping space which has a dimensional number higher than the number of the features constituting the feature information, and the welding quality of a welded joint to be classified is classified based on which of regions of two welding qualities, which are formed by separating the mapping space with a decision boundary, contains the mapped point, and wherein a discriminant function is determined by adopting a weight which minimizes the sum of the classification error corresponding to classification accuracy of a training dataset and a regularization term having a positive correlation with the dimensional number of the discriminant function as weight for each feature constituting the discriminant function indicating the decision boundary.
摘要翻译：关于本发明的焊接质量分类装置是一种装置，其中指示焊接质量未知的待分类的焊接接头的特征信息的数据点被映射到具有高于基于通过将映射空间与判定边界分离而形成的两个焊接质量的区域中的哪一个包含映射点来分类构成特征信息的特征的数量和待分类的焊接接头的焊接质量，并且其中通过采用最小化对应于训练数据集的分类精度的分类误差和与判别函数的维数成正相关的正则化项的正则化项的权重作为构成每个特征的每个特征的权重来确定判别函数判别函数表示决策边界。
