The Hidden Program State Hurts Everyone
(2024)PROCEEDINGS OF THE 2024 ACM SIGPLAN INTERNATIONAL SYMPOSIUM ON NEW IDEAS, NEW PARADIGMS, AND REFLECTIONS ON PROGRAMMING AND SOFTWARE, ONWARD! 2024While visual scaffolding, live programming, and direct manipulation of the program state are considered useful programming paradigms for novices, they might not always offer the same benefits to experienced software developers. In this essay, we will use chess as a proxy for exploring how these paradigms can also support those who have an intuitive understanding of the program state and its connection with textual code. We will consider ...Conference Paper -
Navigating Scaling Laws: Compute Optimality in Adaptive Model Training
(2024)Proceedings of Machine Learning Research ~ Proceedings of the 41st International Conference on Machine LearningIn recent years, the state-of-the-art in deep learning has been dominated by very large models that have been pre-trained on vast amounts of data. The paradigm is very simple: investing more computational resources (optimally) leads to better performance, and even predictably so; neural scaling laws have been derived that accurately forecast the performance of a network for a desired level of compute. This leads to the notion of a ...Conference Paper -

Progress on Event-Based Camera Characterization Techniques including Pre-Launch Measurements of the Falcon ODIN Space Experiment
(2024)UNCONVENTIONAL IMAGING, SENSING, AND ADAPTIVE OPTICS 2024Event-based vision sensor (EVS) technology has expanded the CMOS image sensor design space of low-SWaP sensors with high-dynamic range operation and ability, under certain conditions, to efficiently capture scene information at a temporal resolution beyond that achievable by a typical sensor operating near a 1 kHz frame rate. Fundamental differences between EVS and framing sensors necessitate development of new characterization techniques ...Conference Paper -
A Language Model's Guide Through Latent Space
(2024)Proceedings of Machine Learning Research ~ Proceedings of the 41st International Conference on Machine LearningConcept guidance has emerged as a cheap and simple way to control the behavior of language models by probing their hidden representations for concept vectors and using them to perturb activations at inference time. While the focus of previous work has largely been on truthfulness, in this paper we extend this framework to a richer set of concepts such as appropriateness, humor, creativity and quality, and explore to what degree current ...Conference Paper -
Towards RehabCoach: Design and Preliminary Evaluation of a Conversational Agent Supporting Unsupervised Therapy After Stroke
(2024)2024 10th IEEE RAS/EMBS International Conference for Biomedical Robotics and Biomechatronics (BioRob)Unsupervised therapy after stroke is a promising way to boost therapy dose without significantly increasing the workload on healthcare professionals. However, it raises important challenges, such as lower adherence to therapy in the absence of social interaction with therapists. We present the initial prototype of RehabCoach, a novel smartphone-based app with conversational agent to support unsupervised therapy. RehabCoach is designed to ...Conference Paper -

StegoGAN: Leveraging Steganography for Non-Bijective Image-to-Image Translation
(2024)2024 IEEE/CVF Conference on Computer Vision and Pattern Recognition (CVPR)Most image-to-image translation models postulate that a unique correspondence exists between the semantic classes of the source and target domains. However, this assumption does not always hold in real-world scenarios due to divergent distributions, different class sets, and asymmet- rical information representation. As conventional GANs attempt to generate images that match the distribution of the target domain, they may hallucinate ...Conference Paper -
Comparison of 16 national methods in the life cycle assessment of carbon storage in wood products in a reference building
(2024)IOP Conference Series: Earth and Environmental ScienceWood and bio-based construction products are perceived as a way to use renewable resources, to save energy and to mitigate greenhouse gas (GHG)-emissions during production and to store carbon during the entire service life of the building. This article compares the carbon footprint per kilogram of wood products (softwood beams, plywood, oriented strand board panel, and fibre board) from the perspective of the life cycle assessment methodology ...Conference Paper -

Shadow Health-Related Data: Definition, Categorization, and User Perspectives
(2024)EuroUSEC '24: Proceedings of the 2024 European Symposium on Usable SecurityHealth-related data (HRD) about individuals are increasingly generated and processed. The sources and volume of such data have grown larger over the past years, they include wearable devices, health-related mobile apps, and electronic health records. HRD are sensitive, have important privacy implications, hence hold a special status under existing privacy laws and regulations. In this work, we focus on shadow HRD: these HRD are generated ...Conference Paper -
MUSES: The Multi-sensor Semantic Perception Dataset for Driving Under Uncertainty
(2025)Lecture Notes in Computer Science ~ Computer Vision - ECCV 2024Achieving level-5 driving automation in autonomous vehicles necessitates a robust semantic visual perception system capable of parsing data from different sensors across diverse conditions. However, existing semantic perception datasets often lack important non-camera modalities typically used in autonomous vehicles, or they do not exploit such modalities to aid and improve semantic annotations in challenging conditions. To address this, ...Conference Paper -
Do Vision Foundation Models Enhance Domain Generalization in Medical Image Segmentation?
(2024)Neural networks achieve state-of-the-art performance in many supervised learning tasks when the training data distribution matches the test data distribution. However, their performance drops significantly under domain (covariate) shift, a prevalent issue in medical image segmentation due to varying acquisition settings across different scanner models and protocols. Recently, foundational models (FMs) trained on large datasets have gained ...Conference Paper -
Convergence guarantees for adaptive model predictive control with kinky inference
(2024)Proceedings of Machine Learning ResearchWe analyze the convergence properties of a robust adaptive model predictive control algorithm used to control an unknown nonlinear system. We show that by employing a standard quadratic stabilizing cost function, and by recursively updating the nominal model through kinky inference, the resulting controller ensures convergence of the true system to the origin, despite the presence of model uncertainty. We illustrate our theoretical findings ...Conference Paper -
Exploring Tokenized Product Passports for Circular Construction Supply Chains
(2024)Computing in Construction ~ Proceedings of the 2024 European Conference on Computing in ConstructionA token is a cryptoeconomic entity on a blockchain that can be used to digitally secure, represent, and trade assets. Existing research does not sufficiently explore the use of tokenization as digital representations of physical construction assets within the context of circular supply chains. Thus, this research explores why tokenization for circular construction may be helpful by employing a mixed methods approach via quantitative and ...Conference Paper -
Deep Equilibrium Diffusion Restoration with Parallel Sampling
(2024)2024 IEEE/CVF Conference on Computer Vision and Pattern Recognition (CVPR)Diffusion model-based image restoration (IR) aims to use diffusion models to recover high-quality (HQ) images from degraded images achieving promising performance. Due to the inherent property of diffusion models most existing methods need long serial sampling chains to restore HQ images step-by-step resulting in expensive sampling time and high computation costs. Moreover, such long sampling chains hinder understanding the relationship ...Conference Paper
