Statistical measurement of behavioral effects based on multimodal data

Abstract

The application of multimodal data is particularly important in accurately assessing behavioral effects and optimizing the decision-making process. This type of data provides more comprehensive and in-depth insights by integrating information from different sources and formats. Comprehensive data support not only enhances the science and accuracy of decision-making but also significantly improves the quality of behavioral effectiveness assessment. This study first describes the practical significance and theoretical value of multimodal data in behavioral effect assessment. Subsequently, the types of multimodal data involved and the construction methods of data sets are introduced. In order to demonstrate the role of multimodal data in behavioral effect assessment, the teaching effect of English classroom presentations at a comprehensive university in China is taken as a case study, and the effect of the target behavior was statistically measured based on multimodal data such as students' classroom behavioral videos, images, questionnaires, interviews, and assessment data. The results of the case study show that AI+ demonstrates significant advantages in behavioral effect assessment, which is more objective and effectively avoids the limitations of subjectivity in traditional assessment methods. At the same time, multimodal data helps optimize behavioral effects. For example, the presentations made at the beginning of the class show significant advantages in teaching effect compared with the presentation made before the end of the class, which provides data support and optimization direction for the implementation of teaching activities.
