Abstract :
Multi-Agent Path Finding (MAPF) aims to plan conflict-free joint optimal paths effectively for a group of agents from their respective starting points to destinations. This task is challenging due to its computational complexity. Current works focus on reducing the number of potential conflicts to further decrease the time required for path planning. In this study, we integrate deep learning-based architecture with the sub-dimension expansion method, aiming to transform the multi-agent pathfinding task into an image classification task. We employ visual models as single-agent path planner to predict optimal path based on the observation space of each agent, which reduces the number of conflicts and improves the performance of the planner significantly. The experimental results show that, in comparison to Learning-Assisted M*, our method achieves a reduction in potential conflicts and implements MAPF task effectively only with a minor increase in time consumption.

Abstract :
Differentiable architecture search (DARTS) is an important branch of neural architecture search (NAS), aiming at searching the optimal network structure efficiently. However, the backbone and FPN of the detection model tend to suffer from over-parameterization effects during the search process, resulting in DARTS failing to efficiently search the detection network structure. In this paper, we propose an efficient differentiable architecture search (EDARTS-DET) with backbone and FPN for object detection. Firstly, the joint search space of backbone and FPN networks is designed to facilitate DARTS to search the detection network as a whole at one shot. Secondly, an architecture operation mask weight sharing mechanism is proposed to effectively reduce the search memory occupation and computational cost. Finally, an attention-based partial channel selection strategy is introduced to select important channels to be fed into the search space. The experimental results show that the proposed EDARTS-DET achieves lower search consumption time and memory utilization in the COCO dataset and the Haier appliance disassembly dataset compared with other SOT A methods. Meanwhile, the searched detection networks are also improved in terms of detection performance, verifying that the proposed EDARTS-DET method achieves a well-balanced performance and efficiency.

Abstract :
Crowdsourced on-demand delivery is being required by many industries with the increasing demand of online shopping and on-demand food. However, it is difficult to ensure the delivery efficiency due to the uncertainty of delivery time for crowdsourced couriers in total delivery process. An ant colony algorithm based on total logistics delivery efficiency metrics is proposed in order to ensure the efficiency of crowdsourced on-demand delivery. Firstly, two metrics are designed to describe the total logistics delivery efficiency quantitatively. The average delivery time of each order and the number of orders completed on time are calculated in total logistics delivery efficiency metrics. Secondly, a total logistics crowdsourced on-demand delivery model (TLCODM) is built considering the transport efficiency and order punctuality. This model serves as the fundamental support for crowdsourced on-demand delivery. Finally, an ant colony algorithm based on total logistics delivery efficiency metrics (ACO-TLDE) is proposed to obtain the optimal scheduling solutions. The total logistics delivery efficiency metrics are used to guide the update of ant colony algorithm. The effectiveness of TLCODM and ACO-TLDE are verified by experiments.

Abstract :
Ant colony optimization (ACO) algorithm is widely used in the instant delivery order scheduling because of its distributed computing capability. However, the order delivery efficiency decreases when different logistics statuses are faced. In order to improve the performance of ACO, an adaptive ACO algorithm based on real-time logistics features (AACO-RTLFs) is proposed. First, features are extracted from the event dimension, spatial dimension, and time dimension of the instant delivery to describe the real-time logistics status. Five key factors are further selected from the above three features to assist in problem modeling and ACO designing. Second, an adaptive instant delivery model is built considering the customer's acceptable delivery time. The acceptable time is calculated by emergency order mark and weather conditions in the event dimension feature. Third, an adaptive ACO algorithm is proposed to obtain the instant delivery order schedules. The parameters of the probability equation in ACO are adjusted according to the extracted key factors. Finally, the Gurobi solver in Python is used to perform numerical experiments on the classical datasets to verify the effectiveness of the instant delivery model. The proposed AACO-RTLF algorithm shows its advantages in instant delivery order scheduling when compared to the other state-of-the-art algorithms.

Abstract :
Deep neural networks are important models in the task of recognition of waste electrical appliances. However, deep neural networks are nonlinear models, leading to the lack of self-interpretation of appliance recognition models as a critical issue. We propose an adaptive sparse semantic representation (ASSR) model to improve the self-interpretation capability of appliance recognition models. First, an adaptive sparse representation component is constructed to enhance the ability of the appliance recognition model for sparse feature extraction. Second, residual sparse blocks are designed to ensure reliable network architecture and enhance the semantic representation ability of the appliance recognition model. Finally, the appliance recognition model obtains an interpretable network architecture by computing the optimal sparse solution, ensuring the strong self-interpretability of the recognition model. The experimental results show that the recognition accuracy of ASSR is improved compared with the traditional deep neural network, and ASSR has linear self-interpretation capability.

Abstract :
A large number of unanswered products-related questions appear in the E-commerce platforms, necessitating the deployment of question-answering models to automatically provide precise responses for the user. However, the substantial absence of ground truth presents challenges for implementing supervised learning, and existing unsupervised contrastive learning methods have not addressed this issue fundamentally, with limitations in integrating multi-level features. This paper presents a dual-tower cross-biased contrastive learning model for answer selection, named CCLM-AS. By taking questions and augmented product reviews as positive pairs for unsupervised contrastive learning and employing a dual-tower structure encoder, CCLM-AS learns sentence representations from unlabeled data effectively. Furthermore, the designed training objective realizes multi-level feature integration, including character, sentence and dialogue levels, which enhances the model's inference ability. The experimental results on AmazonQA dataset indicate that our proposed model outperforms existing contrastive learning-based sentence representation models and also achieves comparable performance to supervised answer selection models. This demonstrates that CCLM-AS can not only alleviate the data sparsity problem effectively but also retain the excellent performance.

Abstract :
Multimodal aspect-based sentiment analysis (MABSA) aims to predict the sentiment of aspect by the fusion of different modalities such as image, text and so on. However, the availability of high-quality multimodal data remains limited. Therefore, few-shot MABSA is a new challenge. Previous works are rarely able to cope with low-resource and few-shot scenarios. In order to address the above problems, we design a Few-shot Multimodal aspect-based sentiment analysis framework based on Contrastive Finetuning (FMCF). Initially, the image modality is transformed to the corresponding textual caption to achieve the entailed semantic information and a contrastive dataset is constructed based on similarity retrieval for finetuning in the following stage. Further, a sentence encoder is trained based on SBERT, which combines supervised contrastive learning and sentence-level multi-feature fusion to complete MABSA. The experiments demonstrate that our framework achieves excellent performance in the few-shot scenarios. Importantly, with only 256 training samples and limited computational resources, the proposed method outperforms fine-tuned models that use all available data on the Twitter dataset.

Abstract :
Multi-hop reasoning is critical for natural language understanding but poses challenges for current models, requiring models capable of aggregating and reasoning across multiple sources of information. We propose an Adversarial Entity Graph Convolutional Network (AEGCN) to improve multi-hop inference performance. Unlike previous GNNs-based models, AEGCN places a greater emphasis on the construction of rich entity graph which focuses on identifying the related entities from support document and connecting these entities with innovative edge relationships. The entity graph built by AEGCN preserves both the semantic information and structure of the original text. Further, adversarial training is adopted to generate challenging embeddings for the entity graph, increasing the model's robustness against the interference. The experiments evaluated on WIKIHOP and MEDHOP dataset indicate that AEGCN achieves 6.8 % and 7.7 % accuracy improvement over baseline model respectively, confirming the model's advanced capability in multi-hop reasoning tasks.

Abstract :
summarization models can generate summary auto-regressively, but the quality is often impacted by the noise in the text. Learning cross-sentence relations is a crucial step in this task and the graph-based network is more effective to capture the sentence relationship. Moreover, knowledge is very important to distinguish the noise of the text in special domain. A novel model structure called UGDAS is proposed in this paper, which combines a sentence-level denoiser based on an unsupervised graph-network and an auto-regressive generator. It utilizes domain knowledge and sentence position information to denoise the original text and further improve the quality of generated summaries. We use the recently-introduced dataset CORD-19 (COVID-19 Open Research Dataset) on text summarization task, which contains large-scale data on coronaviruses. The experimental results show that our model achieves the SOTA (state-of-the-art) result on CORD-19 dataset and outperforms the related baseline models on the PubMed Abstract dataset.

Abstract :
Sequential recommendation becomes a critical task in many application scenarios, since people's online activities are increasing. In order to predict the next item that users may be interested, it is necessary to take both general and dynamic preferences of the user into account. Existing approaches typically integrate the useritem or item-item feature interactions directly without considering the dynamic changes of the user's long-term and short-term preferences, which also limits the capability of the model. To address these issues, we propose a novel unified framework for sequential recommendation task, modeling users' long and short-term sequential behaviors at each time step and capturing item-to-item dependencies in higher-order by hierarchical attention mechanism. The proposed model considers the dynamic long and short-term user preferences simultaneously, and a joint learning mechanism is introduced to fuse them for better recommendation. We extensively evaluate our model with several state-of-the-art methods by different validation metrics on three real-world datasets. The experimental results demonstrate the significant improvement of our approach over other compared models.
