‘Predicting GPU Failures With High Precision Under Deep Learning Workloads’
“Graphics processing units (GPUs) are the de facto standard for processing deep learning (DL) tasks. In large-scale GPU clusters, GPU failures are inevitable and may cause severe consequences. For example, GPU failures disrupt distributed training, crash inference services, and result in service level agreement violations. In this paper, we study the problem of predicting GPU failures using machine learning (ML) models to mitigate their damages.” Find the paper and full list of authors in the Proceedings of the 16th ACM International Conference on Systems and Storage.

‘Building Better Human-Agent Teams: Tradeoffs in Helpfulness and Humanness in Voice’
“We manipulate the helpfulness and voice type of a voice-only agent teammate to examine subjective and objective outcomes in twenty teams with one agent and at least three humans during a problem solving task. Our results show that agent helpfulness, but not the humanness of the agent’s voice, significantly alters perceptions of agent intelligence and trust in agent teammates, as well as affects team performance. Additionally, we find that the humanness of an agent’s voice negatively interacts with agent helpfulness to flip its effect on perceived anthropomorphism and perceived animacy.” Find the paper and full list of authors at ArXiv.

‘NNSmith: Generating Diverse and Valid Test Cases for Deep Learning Compilers’
“Deep-learning (DL) compilers such as TVM and TensorRT are increasingly being used to optimize deep neural network (DNN) models to meet performance, resource utilization and other requirements. Bugs in these compilers can result in models whose semantics differ from the original ones, producing incorrect results that corrupt the correctness of downstream applications. … In this work, we propose a new fuzz testing approach for finding bugs in deep-learning compilers.” Find the paper and full list of authors at in the Proceedings of the 28th ACM International Conference on Architectural Support for Programming Languages and Operating Systems.

‘Symmetric Models for Visual Force Policy Learning’
“While it is generally acknowledged that force feedback is beneficial to robotic control, applications of policy learning to robotic manipulation typically only leverage visual feedback. Recently, symmetric neural models have been used to significantly improve the sample efficiency and performance of policy learning across a variety of robotic manipulation domains. This paper explores an application of symmetric policy learning to visual-force problems. We present Symmetric Visual Force Learning (SVFL), a novel method for robotic control which leverages visual and force feedback.” Find the paper and full list of authors at ArXiv.

‘LLM-Powered Conversational Voice Assistants: Interaction Patterns, Opportunities, Challenges, and Design Guidelines’
“Conventional Voice Assistants (VAs) rely on traditional language models to discern user intent and respond to their queries, leading to interactions that often lack a broader contextual understanding, an area in which Large Language Models (LLMs) excel. However, current LLMs are largely designed for text-based interactions, thus making it unclear how user interactions will evolve if their modality is changed to voice. In this work, we investigate whether LLMs can enrich VA interactions via an exploratory study … with varied constraints, stakes and objectivity.” Find the paper and full list of authors at ArXiv.

‘Rethinking Human-AI Collaboration in Complex Medical Decision Making: A Case Study in Sepsis Diagnosis’
“Today’s AI systems for medical decision support often succeed on benchmark datasets in research papers but fail in real-world deployment. This work focuses on the decision making of sepsis, an acute life-threatening systematic infection. … Our aim is to explore the design requirements for AI systems that can support clinical experts in making better decisions for the early diagnosis of sepsis. … We argue that a human-centered AI system needs to support human experts in the intermediate stages of a medical decision-making process, … instead of focusing only on the final decision.” Find the paper and full list of authors…

‘Genomic Signatures of Disease Resistance in Endangered Staghorn Corals’
“White band disease (WBD) has caused unprecedented declines in the Caribbean Acropora corals, which are now listed as critically endangered species. Highly disease-resistant Acropora cervicornis genotypes exist, but the genetic underpinnings of disease resistance are not understood. Using transmission experiments, a newly assembled genome and whole-genome resequencing of 76 A. cervicornis genotypes from Florida and Panama, we identified 10 genomic regions and 73 single-nucleotide polymorphisms that are associated with disease resistance and that include functional protein-coding changes in four genes involved in coral immunity and pathogen detection.” Find the paper and full list of authors in Science.

‘Electric Shock Causes a Fleeing-Like Persistent Behavioral Response in the Nematode Caenorhabditis elegans’
“Behavioral persistency reflects internal brain states, which are the foundations of multiple brain functions. However, experimental paradigms enabling genetic analyses of behavioral persistency and its associated brain functions have been limited. Here, we report novel persistent behavioral responses caused by electric stimuli in the nematode Caenorhabditis elegans. When the animals on bacterial food are stimulated by alternating current, their movement speed suddenly increases 2- to 3-fold, persisting for more than 1 minute even after a 5-second stimulation.” Find the paper and full list of authors at Genetics.

‘Tuning the Default Mode Network With Behavioral Interventions To Address the Youth Mental Health Crisis’
” The surging demand for adolescent mental health care has been declared a crisis by the US Surgeon General, UK and European health officials and pediatric health organizations. Demand for mental health services has broadly outstripped capacity, reducing access to current gold-standard treatments, which, although lifesaving for many, are only effective for a minority of those who use them. Thus, scalable interventions — ideally deployable within and outside clinical settings — are needed to reduce suffering and improve functional outcomes for adolescents.” Find the paper and full list of authors at Nature Mental Health.

‘Lensing in the Blue. II. Estimating the Sensitivity of Stratospheric Balloons to Weak Gravitational Lensing’
“The Superpressure Balloon-borne Imaging Telescope (SuperBIT) is a diffraction-limited, wide-field, 0.5 m, near-infrared to near-ultraviolet observatory designed to exploit the stratosphere’s space-like conditions. SuperBIT’s 2023 science flight will deliver deep, blue imaging of galaxy clusters for gravitational lensing analysis. … We validate our pipeline and forecast SuperBIT survey properties with simulated galaxy cluster observations in SuperBIT’s near-UV and blue bandpasses. We predict imaging depth, galaxy number (source) density and redshift distribution for observations in SuperBIT’s three bluest filters; the effect of lensing sample selections is also considered.” Find the paper and full list of authors at The Astronomical Journal.

‘Large Depth Differences Between Target and Flankers Can Increase Crowding: Evidence From a Multi-Depth Plane Display’
“Crowding occurs when the presence of nearby features causes highly visible objects to become unrecognizable. Although crowding has implications for many everyday tasks and the tremendous amounts of research reflect its importance, surprisingly little is known about how depth affects crowding. Most available studies show that stereoscopic disparity reduces crowding, indicating that crowding may be relatively unimportant in three-dimensional environments. … Using a novel multi-depth plane display, this study investigated how large, real differences in target-flanker depth, representative of those experienced between many objects in the real world, affect crowding.” Find the paper and full list of authors at eLife…

‘”Always Nice and Confident, Sometimes Wrong”: Developer’s Experiences Engaging Generative AI Chatbots Versus Human-Powered Q&A Platforms’
“Software engineers have historically relied on human-powered Q&A platforms, like Stack Overflow (SO), as coding aids. With the rise of generative AI, developers have adopted AI chatbots, such as ChatGPT, in their software development process. Recognizing the potential parallels between human-powered Q&A platforms and AI-powered question-based chatbots, we investigate and compare how developers integrate this assistance into their real-world coding experiences by conducting thematic analysis of Reddit posts. Through a comparative study of SO and ChatGPT, we identified each platform’s strengths, use cases, and barriers.” Find the paper and full list of authors at ArXiv.

‘Semantic Encapsulation Using Linking Types’
“Interoperability pervades nearly all mainstream language implementations, as most systems leverage subcomponents written in different languages. And yet, such linking can expose a language to foreign behaviors that are internally inexpressible, which poses a serious threat to safety invariants and programmer reasoning. … In this paper, we outline an approach that encapsulates foreign code in a sound way — i.e., without disturbing the invariants promised by types of the core language.” Find the paper and full list of authors in the Proceedings of the 8th ACM SIGPLAN International Workshop on Type-Driven Development.
