Ruffle&Riley: Towards the Automated Induction of Conversational Tutoring Systems
No full textConversational tutoring systems (CTSs) offer learning experiences driven by
natural language interaction. They are known to promote high levels of
cognitive engagement and benefit learning outcomes, particularly in reasoning
tasks. Nonetheless, the time and cost required to author CTS content is a major
obstacle to widespread adoption. In this paper, we introduce a novel type of
CTS that leverages the recent advances in large language models (LLMs) in two
ways: First, the system induces a tutoring script automatically from a lesson
text. Second, the system automates the script orchestration via two LLM-based
agents (Ruffle&Riley) with the roles of a student and a professor in a
learning-by-teaching format. The system allows a free-form conversation that
follows the ITS-typical inner and outer loop structure. In an initial
between-subject online user study (N = 100) comparing Ruffle&Riley to simpler
QA chatbots and reading activity, we found no significant differences in
post-test scores. Nonetheless, in the learning experience survey, Ruffle&Riley
users expressed higher ratings of understanding and remembering and further
perceived the offered support as more helpful and the conversation as coherent.
Our study provides insights for a new generation of scalable CTS technologies.Comment: NeurIPS'23 GAIED, Camera-read

Modeling Covarying Responses in Complex Tasks
No full textIn testing situations, participants are often asked for supplementary responses in addition to the primary response of interest, which may include quantities like confidence or reported difficulty. These additional responses can be incorporated into a psychometric model either as a predictor of the main response or as a secondary response. In this paper we explore both of these approaches for incorporating participant’s reported difficulty into a psychometric model using an error rate study of fingerprint examiners. Participants were asked to analyze print pairs and make determinations about the source, which can be scored as correct or incorrect decisions. Additionally, participants were asked to report the difficulty of
the print pair on a five point scale. In this paper, we model (a) the responses of individual examiners without incorporating reported difficulty using a Rasch model, (b) the responses using their reported difficulty as a predictor, and (c) the responses and their reported difficulty as a multivariate response variable. We find that approach (c) results in more balanced classification errors, but incorporating reported difficulty using either approach does not lead to substantive changes in proficiency or difficulty estimates. These results suggest that, while there are individual differences in reported difficulty, these differences appear to be unrelated to examiners’ proficiency in correctly distinguishing matched from non-matched fingerprints.This is a manuscript of a conference proceeding published as Luby, A., Thompson, R.E.

Detecting intestinal ischemia using near infrared spectroscopy
No full textBlood supply to the intestine can suddenly be interrupted. Acute mesenteric intestinal ischemia often requires invasive surgery to restore blood supply to the intestine. Early correction of vascular insufficiency is the most important factor in improving patient survival when confronted with acute mesenteric intestinal ischemia. A prolonged loss of blood flow results in irreversible damage to the intestine that can lead to death. It is also imperative that dead segments of the intestines be removed. Several subjective criteria are relied upon to differentiate viable from non-viable tissue, unfortunately, these criteria can lead to an inaccurate assessment. A porcine model of intestinal ischemia was used to determine the efficacy of using near infrared (NIR) spectroscopy to find ischemic segments of the intestine and detect the onset of reperfusion following resolution of vascular occlusion. Nine segments of intestine were identified and six were assigned to three treatment groups; (1) segments undergoing no vascular manipulations, (2) segments undergoing arterial/venous occlusion and (3) segments undergoing arterial/venous occlusion followed by reperfusion. The remaining segments were used as spacers and interposed between each of the ischemia segments. A classification model, using partial least square discriminant analysis, was built on the spectra collected from the segments with no vascular manipulations and the segments that were solely subjected to arterial/venous occlusion. The spectra collected from the intestinal segments that experienced both occlusion and reperfusion were used to test the classification model. The model was able to detect and distinguish ischemic intestinal tissue with a specificity and sensitivity exceeding 80% with an overall classification accuracy of 89%. The method appears to be well suited as an intra-operative assessment method when intestinal ischemia is a concern.Michael G. Sowa, Elicia Kohlenberg, Jeri R. Payette, Lorenzo Leonardi, Michelle A.
