Knowledge guidance is crucial for bridging the gap between high-level artificial intelligence (AI) ethics principles and the practical implementation of responsible AI systems. diverging from static knowledge inference and temporal interpolation, the task of temporal knowledge extrapolation, which entails predicting future facts based on the evolution of historical facts, poses formidable challenges that remain largely unsolved. In existing temporal extrapolation methods, the structural learning of concurrent facts is primarily addressed by utilizing relation-aware graph neural networks. However, the temporal validity of facts leads to the sparsity of temporal subgraphs, where inherent coarse-level learning mechanisms hinder the capture of nuanced and scarce local semantics. Thus, this article proposes a fine-grained tensor graph attention network (F-GAT) that promotes representation learning of concurrent facts on sparse subgraphs by effectively distinguishing the significance of entities and relations within triplets and acquiring self-attention across diverse triplet contexts. Based on F-GAT, this article proposes a recurrent evolution network [recurrent evolution graph attention network (rE-GAT)] for temporal knowledge extrapolation. rE-GAT employed gated recurrent units to iteratively capture the sequential patterns between adjacent temporal facts, while simultaneously learning enriched embedding through the dual influence of historical factors and structural factors. The competitive results achieved by comparing the entity and relationship prediction performance of the proposed rE-GAT model with advanced methods on six public benchmarks demonstrate the effectiveness of rE-GAT for temporal extrapolation. © 2020 IEEE.

detail reinforcement diffusion Model: Augmentation Fine-Grained Visual Categorization in Few-Shot Conditions

引用

IEEE TrANSACTIONS ON EMErGING TOPICS IN COMPUTATIONAL INTELLIGENCE 2025年第1期9卷 630-640页

The challenge in fine-grained visual categorization (FGVC) lies in how to explore the subtle differences between different subclasses and achieve accurate discrimination. Previous research has relied on large-scale annotated data and pre-trained deep models to achieve the objective. However, when only a limited amount of samples is available, similar methods often struggle to accurately learn the details of instances and perform effective recognition. Using diffusion models for data augmentation has gained widespread attention, but the high level of detail required for fine-grained images makes it challenging for existing methods to be directly employed. To address this issue, we propose a novel approach termed the detail reinforcement diffusion model (drdM), which leverages the extensive knowledge of large models for fine-grained data augmentation and comprises two key components including discriminative semantic recombination (dSr) and spatial knowledge reference (SKr). Specifically, dSr is designed to extract implicit similarity relationships from the labels and reconstruct the semantic mapping between labels and instances, which enables better discrimination of subtle differences between different subclasses. Furthermore, we introduce the SKr module, which incorporates the distributions of different datasets as references in the feature space. This allows the SKr to aggregate the high-dimensional distribution of subclass features in few-shot FGVC tasks, thus expanding the decision boundary. Through these two critical components, we effectively utilize the knowledge from large models to address the issue of data scarcity, resulting in improved performance for fine-grained visual recognition tasks. Extensive experiments demonstrate the consistent performance gain offered by our drdM.

The usage of smartphones holds paramount importance in enhancing the ability of elderly people to live independently. This research aims to explore the various scenarios in which Chinese elderly people employ smartphones for information input, and how input method and Chinese character complexity affect their information input process. To achieve this, we conducted semi-structured interviews to investigate typical situations where Chinese elderly individuals use smartphones to input information. Based on the survey results, we devised an experiment to assess the impact of the input method and Chinese character complexity on the elderly's objective physical load, mental load, input performance, and subjective experience during the inputting process. The findings revealed that the choice of input method significantly affects the objective physical load. distinct input method engaged different major muscle groups during the process. As the Chinese character complexity increased, the elderly's input performance declined, with handwriting input being particularly affected. Thus, we proposed enhancing the current handwriting interface by allowing users to input complex Chinese characters through handwritten pinyin, and simplify the start steps of the handwriting function based on the pinyin input interface. This study contributes to the development of evidence-based guidelines for the aging design of smart mobile devices, thus enhancing the elderly's overall experience in using such technology.

An efficient and highly selective aerobic oxidation of p-methoxybenzyl ethers to aldehydes or ketones with Fe(NO3)3 & sdot;9H2O and TEMPO as catalysts at 25 degrees C has been developed. This method is compatible with versatile functional groups: adamantyl, ether, alkynyl, and alkenyl, etc. due to the mild nature of the reaction conditions, even the highly sensitive optically active aldehydes with an easily racemized alpha-chiral center could be formed from optically active PMB ethers without racemization. Other protecting groups of hydroxyl group remained intact during the current aerobic oxidation. The catalytic protocol has been successfully applied to synthesis of (r)-tert-butyldimethylsilyl hept-1-en-6-yn-4-yl ether, which is the key intermediate for the total synthesis of natural product, (-)-6-O-methylcitreoisocoumarin.
