imagine trying to access home care without a home... in this session, members of the palliative advocacy care team (pact) and palliative carelink will discuss how health and social care workers can adopt approaches to care that recognize and adapt to the social and structural determinants of health. the goal of this session is to challenge providers to re-think traditional models of care, and pursue practices that meet unmet needs of structurally vulnerable populations.

learning objectives:

• explore what it means to take an equity-informed approach to care
• review the concepts of harm reduction, trauma-informed care, and cultural safety
• identify barriers to care and resources for vulnerably housed clients who could benefit from a palliative approach to care

thesis title: argument summarization: enhancing summary generation and evaluation metrics

abstract: in the current era of mass digital information, the need for effective argument summarization has become paramount. this thesis explores the domain of argument summarization, focusing on the development of techniques and evaluation metrics to improve the quality of summarization models. the study first investigates the task of key point analysis, and the challenges associated with previous approaches to it, emphasizing the significance of coverage of the summary. to address these challenges, we propose a novel clustering-based framework that leverages the inherent semantics of arguments to identify and group similar arguments. the proposed approach is evaluated on the benchmark dataset and compared with previous state-of-the-art methods, demonstrating its effectiveness. in addition to the proposed framework, this thesis also presents an analysis of the previous evaluation metric for argument summarization. commonly used metric, rouge is evaluated, revealing its limitation in capturing the nuanced aspects of argument quality. to this end, we introduce new evaluation metrics and methods that consider the coverage and redundancy of the generated summaries, providing more accurate and informative assessments of summarization models. we further show that our evaluation metric has a better correlation with actual summary quality, whereas previous metrics fail to capture this correlation. the implementation is available online.

title: distributed cooperative state estimation and control for multi-agent autonomous systems

abstract

this thesis addresses several problems related to distributed cooperative state estimation and control design for multi-agent rigid-body autonomous systems, namely bearing-based distributed pose estimation, distributed attitude estimation on so(3), and global attitude synchronization on so(3). we consider the distributed pose estimation problem for multi-agent rigid-body systems, under a directed graph topology, assuming that two agents have access to their respective poses. first, we consider the case where all agents have static positions and time-varying orientations, and propose two distributed pose estimation schemes with almost global asymptotic stability guarantees. thereafter, we consider the case where the agents positions and orientations are time-varying, and propose a distributed pose observer with local exponential stability guarantees. the three proposed estimation schemes rely on individual angular velocity (and linear velocity in the case of agents with time-varying positions) measurements and local information exchange between neighboring agents (relative time-varying bearing measurements and estimated poses). we also consider the problem of distributed attitude estimation of multi-agent systems, evolving on so(3), relying on individual angular velocity and relative attitude measurements, under an undirected, connected and acyclic communication graph topology. we propose two distributed attitude observers on so(3); a continuous version and a hybrid version, endowed respectively with almost global asymptotic stability and global asymptotic stability guarantees. in addition, the proposed hybrid attitude estimation scheme is used to solve the pose estimation problem of multi-agent rigid-body systems, with global asymptotic stability guarantees, relying on individual linear and angular velocity measurements as well as local relative bearing and relative orientation measurements. finally, we propose a distributed hybrid attitude synchronization scheme (with and without individual velocity measurements) for a group of rigid body systems evolving on so(3) under an undirected, connected and acyclic communication graph topology, with global asymptotic stability guarantees.
