A financial company is training a generative Al model to predict outcomes of loan applications. The training dataset is small. The dataset categorizes loan applicants as "younger-aged," “"middle-aged," or “older- aged." Most individuals in the dataset are characterized as "middle-aged." The company removes the age range feature from the training dataset. Which model behavior will likely happen as a result of this change to the dataset?
一家金融公司正在训练一个生成式人工智能模型来预测贷款申请的结果。训练数据集规模较小。该数据集将 贷款申请人分为“年轻”“中年”或“老年”三类。数据集中大多数人都被归类为“中年”。 该公司从训练数据集中移除了年龄范围这一特征。 由于数据集的这一变化，哪种模型行为可能会发生？
The model will inaccurately predict outcomes for younger and older age groups.
该模型对较年轻和较年长年龄组的结果预测会不准确。
The model will require less training data.

The model will predict accurate outcomes for only younger age groups.
该模型仅能对较年轻的年龄组做出准确的预测结果。
The model will accurately predict outcomes for all ages.
该模型将能准确预测所有年龄段的结果。
正确答案 A
Removing the age feature eliminates an important variable that differentiates applicant groups. Since the dataset is already imbalanced, the model will generalize based on dominant patterns and lose the ability to account for age-related differences, leading to poorer predictions especially for underrepresented younger and older groups.
去除年龄这一特征会消除一个区分申请人组别的关键变量。由于数据集本身就不平衡，模型将基于占主导地 位的模式进行泛化，从而失去对年龄相关差异的考量能力，导致对代表性不足的年轻和老年群体的预测效果 更差。
