The continuous advancement of robot navigation technology and its deep integration with logistics transportation are gradually driving the direction of indoor logistics towards intelligence. However, most indoor logistics vehicles currently adopt navigation methods based on Simultaneous Localization and Mapping (SLAM) technology, which have certain limitations. These methods rely on map prior knowledge, requiring significant manual labor and high-precision sensors. Moreover, when the environment changes, logistics vehicles often struggle to effectively complete navigation tasks and may even cause safety issues in specific environments. In response to this problem, this paper proposes a new type of navigation model based on deep reinforcement learning. This method constructs a navigation framework suitable for intelligent logistics vehicles on the basis of the classic deep reinforcement learning algorithm TD3 (Twin Delayed Deep Deterministic Policy Gradient). Through training in a simulation environment, this approach has achieved autonomous navigation of mobile robots in unknown environments. Experimental results show that this method has a significant advantage in navigation accuracy compared to traditional navigation algorithms.展开更多

This paper proposes an e-commerce recommendation algorithm (E-KGAT) that integrates knowledge graph (KG) and graph attention (GAT). First, user behavior data and product attributes are combined to construct a collaborative knowledge graph and embedded representation. Then, an embedding propagation layer based on the attention mechanism is designed to capture the interactions and dependencies among nodes. In addition, the node representations of each layer are integrated through the layer aggregation mechanism to predict the user’s matching score for commodities, thus accomplishing the recommendation task. Finally, the binary cross-entropy loss function and Adam optimizer are used to optimize the model performance and ensure that the model accurately learns the embedded representations of users and commodities during training. The experimental results show that by comparing with other algorithms and comparing with the results of ablation experiments, it is proved that the present algorithm not only understands the user preferences more deeply than typical recommendation algorithms, but also accurately captures the complex relationship between commodities, thus realizing higher accuracy and interpretability.展开更多
