Affordance grounding involves not only identifying the shape and appearance of objects, but also understanding how they interact with the environment and users. However, current research faces challenges in accurately localizing affordance regions and addressing previously unseen scenarios. To address these challenges, we propose a weakly supervised multimodal affordance grounding framework, termed MACR-Afford, which combines a Multi-Branch Attention Enhancement module and a multi-stage Chain-of-Thought reasoning module. Under the guidance of a large language model, MACR-Afford improves the ability of intelligent agents to recognize and utilize objects in complex environments. First, we introduce a Multi-Branch Attention Enhancement (MBAE) module to improve the complementarity among object features. By enhancing cross-branch attention and extracting complementary discriminative features, MBAE enables more accurate localization of affordance regions. Subsequently, we introduce a Chain-of-Thought multi-stage reasoning module to generates general affordance knowledge units, which are used to guide the model in localizing affordance-relevant regions. Comprehensive experiments demonstrate that MACR-Afford consistently achieves superior performance in both seen and unseen scenarios, surpassing state-of-the-art baselines across multiple evaluation metrics.

We propose KAN-MoDTI to tackle these challenges by integrating Kolmogorov-Arnold Networks (KAN) with multimodal feature fusion and adaptive gating mechanisms, effectively combining heterogeneous drug and target representations to better capture the complex interactions between them.

In the feature fusion stage, we introduce the FeatureFusionKAN module, which uses a gating mechanism to assign adaptive weights and KAN to perform the integration of heterogeneous modal features. KAN is also utilized in the final prediction layer to enhance the model’s ability to accurately predict complex drug-target interactions.

These limitations are further compounded by computational inefficiencies, hindering real-time decision-making in large-scale or complex traffic environments. To address these issues, this study proposes a VSL strategy based on Heterogeneous Agent Reinforcement Learning with Curriculum Learning (HARLCL). Specifically, a top-level agent classifies road segments using the Mini-Batch K-means algorithm, thereby capturing the heterogeneity of each segment. The lower-level agents operate with class-specific observation spaces and action spaces, each agent observes and acts its feature set tailored to its segment class while sharing the same reward design and learning architecture. Subsequently, lower-level agents adaptively adjust both the position and length of each controlled segment according to classification results and real-time traffic conditions. Through a reward-driven mechanism, these agents continually refine their control precision. Moreover, curriculum learning is introduced during the multi-agent training process, effectively accelerating convergence and mitigating computational burdens typically encountered in large-scale reinforcement learning. Experiments were conducted in three task scenarios–typical fixed bottlenecks, random task bottlenecks, and multiple bottlenecks using realistic road data. The results indicate that training time decreased by 43.18 % and 47.35 %; in the SUMO microscopic simulation, total travel time was 312.25 veh·h, 43.05 % lower than NoVSL, and safe braking distances also decreased, indicating improved safety and more stable traffic flow.
