‘Erasing Concepts From Diffusion Models’
“Motivated by recent advancements in text-to-image diffusion, we study erasure of specific concepts from the model’s weights. While Stable Diffusion has shown promise in producing explicit or realistic artwork, it has raised concerns regarding its potential for misuse. We propose a fine-tuning method that can erase a visual concept from a pre-trained diffusion model, given only the name of the style and using negative guidance as a teacher.” Read the paper and see the full list of authors in ArXiv.

A bellwether of embeddedness: One professor says that ‘the AI system … keeping me alive is ruining my life’
Professor Laura Forlano writes how an insulin pump AI system, which promised to “dynamically adjust blood sugar when compared to the previous linear system,” has actually required such frequent human-computer interactions as to make it medically detrimental. “Rather than dismiss this particular system as bad engineering,” she argues, “it’s more useful to think of it as a bellwether for a world in which autonomous systems are likely to be increasingly embedded in everyday life.” Read “When Things Go Beep in the Night: The AI system that is keeping me alive is ruining my life” at Data & Society: Points.

‘The Paradox of Adaptive Trait Clines With Nonclinal Patterns in the Underlying Genes’
“Multivariate climate change presents an urgent need to understand how species adapt to complex environments. Population genetic theory predicts that loci under selection will form monotonic allele frequency clines with their selective environment, which has led to the wide use of genotype–environment associations (GEAs). This study used a set of simulations to elucidate the conditions under which allele frequency clines are more or less likely to evolve as multiple quantitative traits adapt to multivariate environments.” Read the paper and see the full list of authors in PNAS.

Disability studies research incorporated into robotic sculpture
Laura Forlano, professor of art and design and communication studies, has had her work featured in a “robotic sculpture” designed by multimedia artist Itziar Barrio. “Some of the sculptures are programmed and inscribed with text that Forlano, a Type 1 diabetic, transcribed from the alert and alarm history from her ‘smart’ insulin pump and then annotated with field notes,” writes Smack Mellon, Barrio’s exhibition space in Brooklyn, New York. The exhibition’s title, “did not feel low, was sleeping,” is sourced from one of the sculptures in Barrio’s collaboration with Forlano. The exhibition ran from March to April, 2023.

‘Automated Grading of Automata With ACL2s’
“Almost all Computer Science programs require students to take a course on the Theory of Computation (ToC) which covers various models of computation. … ToC courses tend to give assignments that require paper-and-pencil solutions. Grading such assignments takes time, so students typically receive feedback for their solutions more than a week after they complete them. We present the Automatic Automata Checker (A2C), an open source library that enables one to construct executable automata using definitions that mimic those found in standard textbooks.” Read the paper and see the full list of authors in ArXiv.

‘A General Theory of Correct, Incorrect and Extrinsic Equivariance’
“Although equivariant machine learning has proven effective at many tasks, success depends heavily on the assumption that the ground truth function is symmetric over the entire domain matching the symmetry in an equivariant neural network. A missing piece in the equivariant learning literature is the analysis of equivariant networks when symmetry exists only partially in the domain. … We propose pointwise definitions of correct, incorrect, and extrinsic equivariance, which allow us to quantify continuously the degree of each type of equivariance a function displays.” Read the paper and see the full list of authors in ArXiv.

‘Model Sketching: Centering Concepts in Early-Stage Machine Learning Model Design’
“Machine learning practitioners often end up tunneling on low-level technical details like model architectures and performance metrics. Could early model development instead focus on high-level questions of which factors a model ought to pay attention to? Inspired by the practice of sketching in design, which distills ideas to their minimal representation, we introduce model sketching: a technical framework for iteratively and rapidly authoring functional approximations of a machine learning model’s decision-making logic.” Read the paper and see the full list of authors in ArXiv.

‘Ungrading With Empathy: An Experiment in Ungrading for Intermediate Data Science’
“We implemented a model for grading weekly assignments in an intermediate data science course that explicitly gave students useful feedback on their code while not evaluating it on the traditional metrics of correctness or style. … Our ungrading policy was designed to extend empathy towards students and to give them useful, actionable feedback. Our policy reduced the stress that students felt each week, stabilized the amount of time they spent on assignments, and ask them to reflect on their code to request feedback from the teaching team.” Find the paper and the full list of authors in the SIGCSE 2023…

‘WADER at SemEval-2023 Task 9: A Weak-Labelling Framework for Data Augmentation in Text Regression Tasks’
“Intimacy is an essential element of human relationships and language is a crucial means of conveying it. Textual intimacy analysis can reveal social norms in different contexts and serve as a benchmark for testing computational models’ ability to understand social information. In this paper, we propose a novel weak-labeling strategy for data augmentation in text regression tasks called WADER.” Read the paper and see the full list of authors in ArXiv.

‘Online Paging With Heterogeneous Cache Slots’
“It is natural to generalize the online k-Server problem by allowing each request to specify not only a point p, but also a subset S of servers that may serve it. … We focus on uniform and star metrics. For uniform metrics, the problem is equivalent to a generalization of Paging in which each request specifies not only a page p, but also a subset S of cache slots, and is satisfied by having a copy of p in some slot in S.” Read the paper and see the full list of authors in the Dagstuhl Research Online Publication Server.

‘A Flexible Formative/Summative Grading System for Large Courses’
“We designed a formative/summative grading system in our CS0 and CS1 classes for both on-campus and online students to support a structured growth mindset. Students can redo formative assignments and are provided flexible deadlines. They demonstrate their mastery in summative assignments. While being inspired by other grading systems, our system works seamlessly with auto-grading tools used in large, structured courses. … These students went to the traditional follow-on CS2 course and 94% passed compared with 71% who took CS1 with a traditional grading system.” Read the paper and see the full list of authors in the proceedings of SIGCSE 2023.
