There has been a proliferation of emotion-related interactive textiles in recent years. This research conducted a comprehensive scoping review of the literature on emotion-related interactive textiles design. In total, 75 design studies were identified from their abstracts and analyzed with social network analysis and text mining methods. These studies were categorized into different aims (emotion expression, emotion communication, emotion reflection, emotion regulation, emotional effect, emotional experience, and emotion analysis). This review also analyzed details of prototypes and experimental design, such as textile form, textile function, feedback mechanism, experiment method, evaluation scale, and empirical findings. Then we evaluated these studies based on the relationship of their research aim, textiles, emotion, interaction mechanism, etc. The findings suggest that interactive textiles can aid in emotion presentation, modulation, and creating unique emotional experiences. Interactive textiles, feedback mechanisms, and bodily interaction all serve essential functions and benefit emotional interaction. Last, this review reflected on the critical research directions of emotion-related interactive textiles, including connecting interactive textiles with biofeedback, designing interactive textiles with sensory feedback mechanisms, and increasing bodily interaction for dynamic emotion. Further, this research provided insights into the research gaps, from elaborating on the experiment and exploring the materiality of interactive textiles to concerning privacy and user acceptance. Interactive textiles bridge textiles and emotion together to aid emotional well-being in people’s daily lives. © The Author(s), under exclusive licence to Springer-Verlag London Ltd., part of Springer Nature 2024.

While the multi-view 3D reconstruction task has made significant progress, existing methods simply fuse multi-view image features without effectively leveraging available auxiliary information, especially the viewpoint information for guiding and associating features of different views. To this end, we propose to enhance multi-view 3D reconstruction with the power of viewpoint information. Specifically, a simple-yet-effective viewpoint estimator is designed to learn and provide comprehensive viewpoint knowledge for locating and associating learned features from different views. Moreover, to improve the 3D reconstruction quality when 2D images of only very few viewpoints are available, we propose to learn the shape prior knowledge to provide sufficient shape information for compensating the limited 2D observations. Overall, we present VIPNet, benefiting from Viewpoint Information and Shape Prior learning for high-quality multi-view 3D reconstruction. Extensive experiments validate the effectiveness of the proposed VIPNet, which achieves state-of-the-art performance on challenging datasets and shows well generalization ability in real-world scenarios. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025.

Boundedly Rational Agents in Sequential Posted Pricing

We consider the well-studied sequential posted pricing scenarios. In these scenarios, an auctioneer typically learns the value distributions of all agents as prior information and then offers a take-it-or-leave-it price to each sequentially coming agent. If the value distributions are correctly learned, the dominant strategy of each agent is telling the truth. However, an agent could manipulate her value distribution to exploit the auctioneer. We study the behavior of sophisticated agents predicted by two prominent bounded rationality models: the level-fc and the cognitive hierarchy models. We begin with analyzing the structure of the optimal reported distributions and then provide algorithms to compute the optimal distributions for each model. In the continuous scenarios, we show that both models are ill-defined by some examples. Moreover, we evaluate both models in discrete scenarios with different numbers of agents, different minimum units of the values, and different risk tolerances. The empirical results and a brief discussion about the Bayesian Nash equilibrium of the experimental scenarios show that both the level-fc model and the equilibrium suggest the highest possible prices. In contrast, the cognitive hierarchy model suggests low prices. The level-fc model and the equilibrium somehow explain the "winner’s curse" in online markets. The models and the equilibrium fail to explain that the same item could have different prices in different shops. To explain the different-price phenomenon, we suggest trying other bounded rationality models for agents and/or considering the auctioneers with bounded rationality. © 2023, Shanghai Jiao Tong University.

Objective To develop a few-shot learning(FSL) approach for classifying optical coherence tomography(OCT) images in patients with inherited retinal disorders(IRDs).Methods In this study, an FSL model based on a student–teacher learning framework was designed to classify images. 2,317 images from 189 participants were included. Of these, 1,126 images revealed IRDs, 533 were normal samples, and 658 were control *** The FSL model achieved a total accuracy of 0.974–0.983, total sensitivity of 0.934–0.957, total specificity of 0.984–0.990, and total F1 score of 0.935–0.957, which were superior to the total accuracy of the baseline model of 0.943–0.954, total sensitivity of 0.866–0.886, total specificity of 0.962–0.971,and total F1 score of 0.859–0.885. The performance of most subclassifications also exhibited advantages. Moreover, the FSL model had a higher area under curves(AUC) of the receiver operating characteristic(ROC) curves in most *** This study demonstrates the effective use of the FSL model for the classification of OCT images from patients with IRDs, normal, and control participants with a smaller volume of data. The general principle and similar network architectures can also be applied to other retinal diseases with a low prevalence.

Video diffusion models are able to generate high-quality videos by learning strong spatial-temporal priors on large-scale datasets. In this paper, we aim to investigate whether such priors derived from a generative process are suitable for video recognition, and eventually joint optimization of generation and recognition. Building upon Stable Video Diffusion, we introduce GenRec, the first unified framework trained with a random-frame conditioning process so as to learn generalized spatial-temporal representations. The resulting framework can naturally supports generation and recognition, and more importantly is robust even when visual inputs contain limited information. Extensive experiments demonstrate the efficacy of GenRec for both recognition and generation. In particular, GenRec achieves competitive recognition performance, offering 75.8% and 87.2% accuracy on SSV2 and K400, respectively. GenRec also performs the best on class-conditioned image-to-video generation, achieving 46.5 and 49.3 FVD scores on SSV2 and EK-100 datasets. Furthermore, GenRec demonstrates extraordinary robustness in scenarios that only limited frames can be observed.

The physical world we live in is accelerating digitalization with the vigorous development of Internet of Things (IoT). Following this trend, Web of Things (WoT) further enables fast and efficient creation of various applications that perceive and act on the physical world using standard Web technologies. A popular way for creating WoT applications is Trigger-Action Programming (TAP), which allows users to orchestrate the capabilities of IoT devices in the form of "if trigger, then action". However, existing TAP approaches don't support scenario-centric WoT applications which involve abstract modeling of physical environments and complex spatio-temporal dependencies between events and actions. In this paper, we propose an approach called SCTAP which supports Scenario-Centric Trigger-Action Programming based on software-defined physical environments. SCTAP defines a structured and conceptual representation for physical environments, which provides the required programming abstractions for WoT applications. Based on the representation, SCTAP defines a grammar for specifying scenario-centric WoT applications with spatio-temporal dependencies. Furthermore, we design a service-based architecture for SCTAP which supports the integration of device access, event perception, environment representation, and rule execution in a loosely-coupled and extensible way. We implement SCTAP as a WoT infrastructure and evaluate it with two case studies including a smart laboratory and a smart coffee house. The results confirm the usability, feasibility and efficiency of SCTAP and its implementation. © 2023 ACM.

Text irregularities pose significant challenges to scene text recognizers. Thin-Plate Spline (TPS)based rectification is widely regarded as an effective means to deal with them. Currently, the calculation of TPS transformation parameters purely depends on the quality of regressed text borders. It ignores the text content and often leads to unsatisfactory rectified results for severely distorted text. In this work, we introduce TPS++, an attention-enhanced TPS transformation that incorporates the attention mechanism to text rectification for the first time. TPS++ formulates the parameter calculation as a joint process of foreground control point regression and content-based attention score estimation, which is computed by a dedicated designed gated-attention block. TPS++ builds a more flexible content-aware rectifier, generating a natural text correction that is easier to read by the subsequent recognizer. Moreover, TPS++ shares the feature backbone with the recognizer in part and implements the rectification at feature-level rather than image-level, incurring only a small overhead in terms of parameters and inference time. Experiments on public benchmarks show that TPS++ consistently improves the recognition and achieves state-of-the-art accuracy. Meanwhile, it generalizes well on different backbones and recognizers.

The multiplication of a sparse matrix with a dense vector is a vital operation in linear algebra, with applications in numerous contexts. After earlier research on FPGA acceleration of this operation had shown the potential to achieve a high bandwidth efficiency, this workload has received renewed attention with the introduction of high bandwidth memory on FPGA platforms. However, previous designs fell short of scaling to the full bandwidth potential of current FPGA platforms with high bandwidth memory. In this work, we present HiHiSpMV with a novel design approach around hierarchical accumulation, which allows us to overcome several limitations of the related work. Our design is completely implemented with high-level synthesis and compiled with Vitis, and instantiates 16 independent compute units, each processing up to 16 matrix elements per clock cycle. The reduction of these elements is performed without any latency or resource overhead and the subsequent accumulation uses the well-established shift-register design pattern. Due to the independent nature of compute units, our design can connect to all of the 32 high bandwidth memory pseudo-channels in 512-bit interface mode on an Alveo U280 FPGA board. In our tests, we reach up to 86% of the theoretical available bandwidth of this FPGA platform, enabling a computational throughput of up to 98 GFLOPS. This is about 1.5 × faster than the peak throughput of the best related work in that regard, Serpens. On average, the throughput of HiHiSpMV is even 2.7× higher than Serpens. © 2024 IEEE.

Studying the genomic diversity of viruses can help us understand how viruses evolve and how that evolution can impact human health. Rather than use a laborious and tedious wet-lab approach to conduct a genomic diversity study, we take a computational approach, using the ubiquitous NCBI BLAST and our parallel and distributed SparkLeBLAST, across 53 patients (40,000,000 query sequences) on Fugaku, the world's fastest homogeneous supercomputer with 158,976 nodes, where each code contains a 48-core A64FX processor and 32 GB RAM. To project how long BLAST and SparkLeBLAST would take to complete a genomic diversity study of COVID-19, we first perform a feasibility study on a subset of 50 query sequences from a single COVID-19 patient to identify bottlenecks in sequence alignment processing. We then create a model using Amdahl's law to project the run times of NCBI BLAST and SparkLeBLAST on supercomputing systems like Fugaku. Based on the data from this 50-sequence feasibility study, our model predicts that NCBI BLAST, when running on all the cores of the Fugaku supercomputer, would take approximately 26.7 years to complete the full-scale study. In contrast, SparkLeBLAST, using both our query and database segmentation, would reduce the execution time to 0.026 years (i.e., 22.9 hours) - resulting in more than a 10,000× speedup over using the ubiquitous NCBI BLAST. © 2024 IEEE.

Metaphors are everywhere. They appear extensively across all domains of natural language, from the most sophisticated poetry to seemingly dry academic prose. A significant body of research in the cognitive science of language argues for the existence of conceptual metaphors, the systematic structuring of one domain of experience in the language of another. Conceptual metaphors are not simply rhetorical flourishes but are crucial evidence of the role of analogical reasoning in human cognition. In this paper, we ask whether Large Language Models (LLMs) can accurately identify and explain the presence of such conceptual metaphors in natural language data. Using a novel prompting technique based on metaphor annotation guidelines, we demonstrate that LLMs are a promising tool for large-scale computational research on conceptual metaphors. Further, we show that LLMs are able to apply procedural guidelines designed for human annotators, displaying a surprising depth of linguistic knowledge. © 2024 Copyright for this paper by its authors.
