'discriminant'是英语单词,可以翻译为“判别式”。在数学中,判别式是用于解一元二次方程的公式中的一个参数,可以帮助我们判断方程的解的性质。此外,在机器学习和数据分析中,判别式也是一种经常被使用的方法,用于分类和聚类等任务中。
以下是9个含有'discriminant'的例句:
1. The discriminant of the quadratic equation is negative, so it has no real solutions.(这个二次方程的判别式为负,所以它没有实数解。)
2. The discriminant analysis helps us find the most important variables for distinguishing different groups.(判别分析能帮助我们找到最重要的变量,从而区分不同的组。)
3. The discriminant function has a high accuracy in predicting the classification of new data.(判别函数在预测新数据的分类方面具有很高的准确度。)
4. The discriminant power of this test is very low, which means it cannot distinguish between different conditions effectively.(这个测试的判别能力非常低,意味着它不能有效地区分不同的情况。)
5. By calculating the discriminant, we can determine whether a given quadratic equation has real solutions or not.(通过计算判别式,我们可以确定一个给定的二次方程是否有实数解。)
6. The discriminant plot shows how well the different clusters can be separated by the chosen variables.(判别图显示了通过选定的变量能够将不同的簇分离开的程度。)
7. The discriminant analysis is often used in market research to identify different consumer segments based on their preferences and behaviors.(判别分析常常被用于市场调研,以基于消费者的偏好和行为来识别不同的消费者群体。)
8. The discriminant function analysis is a powerful tool for predicting the likelihood of an individual to belong to a certain group.(判别函数分析是预测个体属于某个特定群体的可能性的一种强有力的工具。)
9. The discriminant validity of the questionnaire was tested by comparing scores between different groups that should theoretically have different levels of the measured construct.(通过比较理论上应该具有不同的测量构念水平的不同群体的得分,测试了问卷的判别效度。)
