Data Lineage Resolver For Grounding Large Language Model Inference, Hari Bhaskar S

Defensive Publications Series

An important challenge when using LLMs in business applications is to account for different sources of information that have conflicting values for the same data at the time the LLM performs the inference task based on such data. When multiple potentially conflicting sources of data are available, LLMs used in business applications may need grounding with facts. This disclosure describes a data lineage resolver that can utilize a data lineage catalog to enable LLM output to be verified for grounding based on the data source(s) used for the output and once verified, provided to the business application. The data lineage …

The purpose of this study was to evaluate the effectiveness of traditional and active lecture methods in higher-education courses. A multiple group convergent parallel mixed method design was used, with measurement of learning, attention, and student preference for active or traditional lecture methods. Six faculty at a public university in the northeast region of the United States engaged 178 undergraduate and graduate students in a traditional lecture session and an active lecture session during the Spring 2022 semester. Results indicated effectiveness of active and traditional lecture approaches (p < .05). Analysis of qualitative and quantitative data in the study provides additional information regarding student preference for active lecture based on perceptions of increased learning benefits, interaction/engagement, attention, activities, discussion, and the use of multimedia. In implementing both traditional and active lecture sessions this study employed pre-lecture and post-lecture quizzes that students found to be very beneficial to learning.
