An Assessment of University Infrastructure Impact on the Safety of Individuals with Physical Disabilities at the University of Texas at Austin - Poster
Personal safety at the University of Texas is an increasingly popular topic of conversation between students, staff, faculty, and University administration. Concerns stemming from the recently passed “Campus Carry” legislation and the on-campus murder of an undergraduate student that occurred in the spring of 2016 spark debate over the utility of various safety resources currently available on-campus. However, the accessibility of said resources is hardly addressed. Per the 2010 U.S. Census, over 15% of U.S. adults identify as having any physical functioning difficulty. As the University of Texas campus hosts tens of thousands of adults each day, this thesis was conducted to address the flowing overarching question: How does the physical infrastructure of current safety resources on the University of Texas at Austin campus impact the safety of students, faculty, and staff with physical disabilities?
To address this question, a survey was developed based on 2 semi-structured interviews gauging safety concerns with individuals from the disabled community, news articles documenting the use of campus safety resources, and University published documents. The survey underwent content review by 4 subject matter experts in areas such as civil engineering, campus diversity and community engagement, and the Americans with Disabilities act of 1990. Social media platforms such as Facebook and email list serves for various groups at the University of Texas were used to distribute the survey. It is expected that the results of the survey will indicate the perceptions of current and former students, faculty, and staff will underestimate the prevalence and use and overestimate the accessibility of certain safety resources mentioned in the survey. This poster is a summarized presentation of the findings from the survey.Civil, Architectural, and Environmental Engineerin
A direct proof that has generalized roundness zero
Metric spaces of generalized roundness zero have interesting non-embedding
properties. For instance, we note that no metric space of generalized roundness
zero is isometric to any metric subspace of any -space for which . Lennard, Tonge and Weston gave an indirect proof that
has generalized roundness zero by appealing to highly
non-trivial isometric embedding theorems of Bretagnolle Dacunha-Castelle and
Krivine, and Misiewicz. In this paper we give a direct proof that
has generalized roundness zero. This provides insight
into the combinatorial geometry of that causes the
generalized roundness inequalities to fail. We complete the paper by noting a
characterization of real quasi-normed spaces of generalized roundness zero.Comment: The first version of this paper had the title "The generalized
roundness of revisited". This version includes some minor
modifications of the text and corrections to several typographic error
Leveraging Implicit Feedback from Deployment Data in Dialogue
We study improving social conversational agents by learning from natural
dialogue between users and a deployed model, without extra annotations. To
implicitly measure the quality of a machine-generated utterance, we leverage
signals like user response length, sentiment and reaction of the future human
utterances in the collected dialogue episodes. Our experiments use the publicly
released deployment data from BlenderBot (Xu et al., 2023). Human evaluation
indicates improvements in our new models over baseline responses; however, we
find that some proxy signals can lead to more generations with undesirable
properties as well. For example, optimizing for conversation length can lead to
more controversial or unfriendly generations compared to the baseline, whereas
optimizing for positive sentiment or reaction can decrease these behaviors.Comment: EACL 202
Language Models that Seek for Knowledge: Modular Search & Generation for Dialogue and Prompt Completion
Language models (LMs) have recently been shown to generate more factual
responses by employing modularity (Zhou et al., 2021) in combination with
retrieval (Adolphs et al., 2021). We extend the recent approach of Adolphs et
al. (2021) to include internet search as a module. Our SeeKeR (Search
engine->Knowledge->Response) method thus applies a single LM to three modular
tasks in succession: search, generating knowledge, and generating a final
response. We show that, when using SeeKeR as a dialogue model, it outperforms
the state-of-the-art model BlenderBot 2 (Chen et al., 2021) on open-domain
knowledge-grounded conversations for the same number of parameters, in terms of
consistency, knowledge and per-turn engagingness. SeeKeR applied to topical
prompt completions as a standard language model outperforms GPT2 (Radford et
al., 2019) and GPT3 (Brown et al., 2020) in terms of factuality and topicality,
despite GPT3 being a vastly larger model. Our code and models are made publicly
available
