A traditional A-Star (A*) algorithm generates an optimal path by minimizing the cost. For a vessel, factors of length, obstacle collision risk, traffic separation rule and manoeuvrability restriction should be all taken into account for planning. Meanwhile, water current also plays important role in voyaging berthing vessels. In consideration these defects when it is used vessel planning, improved has been proposed. To specific, risk models obstacles (bridge pier, moored or anchored ship,...

Recently, IQA has witnessed notable surge innovative research efforts, driven by emergence novel architectural paradigms sophisticated computational techniques. This survey delivers an extensive analysis contemporary methodologies, organized according to their application scenarios, serving as beneficial...
Abstract Since vessel dynamics could vary during maneuvering because of load changes, speed changing, environmental disturbances, aging mechanism, etc., the performance model‐based path following control may be degraded if controller uses same motion model all time. This article proposes an adaptive method based on least squares support vector machines (LS‐SVM) to deal with parameter changes model. The consists two components: online identification varying parameters and predictive (MPC)...
Low quality automatic identification system (AIS) data often mislead analysts to a misunderstanding of ship behavior analysis and making incorrect navigation risk assessments. It is therefore necessary accurately understand judge the problems in AIS before further behavior. Outliers were filtered existing methods based only on mathematical models where related are not utilized there lack visual exploration. Thus, human brain’s ability cannot be fully think visually for reasoning. In this...
To learn the optimal collision avoidance policy of merchant ships controlled by human experts, a finite-state Markov decision process model for ship is proposed based on analysis mechanism, and an inverse reinforcement learning (IRL) method cross entropy projection to obtain from expert’s demonstrations. Collision simulations in different encounters are conducted results show that obtained IRL has good inversion effect two kinds which indicate can effectively experts avoidance.
Rich image information is one of the important means through which unmanned surface vehicles effectively and reliably identify targets during autonomous navigation. However, adaptability traditional artificial design feature methods in target representation differentiation remains limite d due to diversity ship types, different scales, complex dynamic outdoor scenes. This study proposed a recognition method based on single shot multi-box detector (SSD) deep learning. First, training test...

Adam with decoupled weight decay, also known as AdamW, is widely acclaimed for its superior performance in language modeling tasks, surpassing $\ell_2$ regularization terms of generalization and optimization. However, this advantage not theoretically well-understood. One challenge here that though intuitively optimizes the regularized loss, it clear if AdamW a specific objective. In work, we make progress toward understanding benefit by showing implicitly performs constrained More...
