However, in numerous real-world scenarios, certain tasks usually necessitate distinct, specialized knowledge. The mixing of these different task-specific knowledge often results in gradient conflicts during the optimization process, posing a significant challenge in the design of effective multi-task learning systems. This study proposes a straightforward yet effective multi-task learning framework that employs groups of expert networks to decouple the learning of task-specific knowledge and mitigate such gradient conflicts. Specifically, this approach partitions the feature channels into task-specific and shared components. The task-specific subsets are processed by dedicated experts to distill specialized knowledge. The shared features are captured by a point-wise aggregation layer from the whole outputs of all experts, demonstrating superior performance in capturing inter-task interactions. By considering both task-specific knowledge and shared features, the proposed approach exhibits superior performance in multi-task learning. Extensive experiments conducted on the PASCAL-Context and NYUD-v2 datasets have demonstrated the superiority of the proposed approach compared to other state-of-the-art methods. Furthermore, a benchmark dataset for multi-task learning in underwater scenarios has been developed, encompassing object detection and underwater image enhancement tasks. Comprehensive experiments on this dataset consistently validate the effectiveness of the proposed multi-task learning strategy.

Researchers have proposed various methods for explaining neural networks to address this challenge. This paper focuses on rule-based explanations for neural network classification problems. We propose IRCnet, a scalable classification model based on first-order logic rules. IRCnet consists of layers for learning conjunction and disjunction rules, utilizing binary logic activation functions to enhance interpretability. The model is initially trained using a continuous-weight version, which is later binarized to produce a discrete-weight version. During training, we innovatively employed gradient approximation method to handle the non-differentiable weight binarization function, thereby enabling the training of split matrices used for binarization. Finally, Conjunctive Normal Form (CNF) or Disjunctive Normal Form (DNF) rules are extracted from the model’s discrete-weight version. Experimental results indicate that our model achieves the highest or near-highest performance across various classification metrics in multiple structured datasets while demonstrating significant scalability.

Existing deep learning and non-deep learning techniques for video summarization have certain limitations.

Such clickbait not only facilitates the spread of fake news and misinformation but also enables click-jacking attacks, redirecting users to deceptive websites that steal personal information. These harmful activities can result in significant losses and serious repercussions. The widespread presence of clickbait underscores both the importance and the challenges of developing effective detection methods. To date, the research paradigm of clickbait detection evolved from deep neural networks to fine-tuned Pre-trained Language Models (PLMs) and, more recently, into prompt-tuning models. However, these methods may suffer two main limitations: (1) they fail to utilize the multi-modal context information in news or posts and explore the higher-level feature representations to enhance the performance of clickbait detection; (2) they largely ignore the diverse range of Chinese expressive forms and neglect the complex semantics and syntactic structures of textual content to assist in learning a better news representation. To overcome these limitations, we proposed a Multi-modal Soft Prompt-tuning Method (MSP) for Chinese Clickbait Detection, which jointly models the textual and image information into a continuous prompt embedding as the input of PLMs. Specifically, firstly, the soft prompt-tuning model including Graph Attention Network and Contrastive Language-Image Pre-training are employed to learn the feature representations of texts and images in news or posts, respectively. Then the obtained text and image representations are re-input into the soft prompt-tuning model with automatic template generation.
