As the complexity of modern software continues to escalate, software engineering has become an increasingly daunting and error-prone endeavor. In recent years, the field of Neural Code Intelligence (NCI) has emerged as a promising solution, leveraging the power of deep learning techniques to tackle analytical tasks on source code with the goal of improving programming efficiency and minimizing human errors within the software industry. Pretrained language models have become a dominant force in NCI research, consistently delivering state-of-the-art results across a wide range of tasks, including code summarization, generation, and translation. In this paper, we present a comprehensive survey of the NCI domain, including a thorough review of pretraining techniques, tasks, datasets, and model architectures. We hope this paper will serve as a bridge between the natural language and programming language communities, offering insights for future research in this rapidly evolving field.

Assembly planning is the core of automating product assembly, maintenance, and recycling for modern industrial manufacturing. Despite its importance and long history of research, planning for mechanical assemblies when given the final assembled state remains a challenging problem. This is due to the complexity of dealing with arbitrary 3D shapes and the highly constrained motion required for real-world assemblies. In this work, we propose a novel method to efficiently plan physically plausible assembly motion and sequences for real-world assemblies. Our method leverages the assembly-by-disassembly principle and physics-based simulation to efficiently explore a reduced search space. To evaluate the generality of our method, we define a large-scale dataset consisting of thousands of physically valid industrial assemblies with a variety of assembly motions required. Our experiments on this new benchmark demonstrate we achieve a state-of-the-art success rate and the highest computational efficiency compared to other baseline algorithms. Our method also generalizes to rotational assemblies (e.g., screws and puzzles) and solves 80-part assemblies within several minutes.

从点云中检测3D对象是一项实用但充满挑战的任务,最近引起了越来越多的关注。在本文中,我们提出了针对3D对象检测的标签引导辅助训练方法(LG3D),该方法是增强现有3D对象检测器的功能学习的辅助网络。具体而言,我们提出了两个新型模块:一个标签 - 通道诱导器,该模块诱导器将框架中的注释和点云映射到特定于任务的表示形式和一个标签 - 知识式插曲器,该标签知识映射器有助于获得原始特征以获得检测临界表示。提出的辅助网络被推理丢弃,因此在测试时间没有额外的计算成本。我们对室内和室外数据集进行了广泛的实验,以验证我们的方法的有效性。例如,我们拟议的LG3D分别在SUN RGB-D和SCANNETV2数据集上将投票人员分别提高了2.5%和3.1%的地图。

360 {\ TextDegree}视频的盲目视觉质量评估(BVQA)在优化沉浸式多媒体系统中起着关键作用。在评估360 {\ TextDegree}视频的质量时,人类倾向于从每个球形帧的基于视口的空间失真来识别其在相邻帧中的运动伪影,以视频级质量分数为止,即渐进性质量评估范式。然而,现有的BVQA方法对于360 {\ TextDegree}视频忽略了这条范式。在本文中,我们考虑了人类对球面视频质量的逐步范例,因此提出了一种新颖的BVQA方法(即ProvQA),通过逐步学习从像素,帧和视频中逐步学习。对应于像素,帧和视频的渐进学习,三个子网被设计为我们的PROPQA方法,即球形感知感知质量预测(SPAQ),运动感知感知质量预测(MPAQ)和多帧时间非本地(MFTN)子网。 SPAQ子网首先模拟基于人的球面感知机制的空间质量下降。然后,通过跨越相邻帧的运动提示,MPAQ子网适当地结合了在360 {\ TextDegree}视频上的质量评估的运动上下文信息。最后,MFTN子网聚集多帧质量劣化,通过探索来自多个帧的长期质量相关性来产生最终质量分数。实验验证了我们的方法在两个数据集中的360 {\ TextDegree}视频上显着提高了最先进的BVQA性能,该代码是公共\ url {https://github.com/yanglixiaoshen/的代码Provqa。}

Recently, contrastive learning (CL) has emerged as a successful method for unsupervised graph representation learning. Most graph CL methods first perform stochastic augmentation on the input graph to obtain two graph views and maximize the agreement of representations in the two views. Despite the prosperous development of graph CL methods, the design of graph augmentation schemes-a crucial component in CL-remains rarely explored. We argue that the data augmentation schemes should preserve intrinsic structures and attributes of graphs, which will force the model to learn representations that are insensitive to perturbation on unimportant nodes and edges. However, most existing methods adopt uniform data augmentation schemes, like uniformly dropping edges and uniformly shuffling features, leading to suboptimal performance. In this paper, we propose a novel graph contrastive representation learning method with adaptive augmentation that incorporates various priors for topological and semantic aspects of the graph. Specifically, on the topology level, we design augmentation schemes based on node centrality measures to highlight important connective structures. On the node attribute level, we corrupt node features by adding more noise to unimportant node features, to enforce the model to recognize underlying semantic information. We perform extensive experiments of node classification on a variety of real-world datasets. Experimental results demonstrate that our proposed method consistently outperforms existing state-of-the-art baselines and even surpasses some supervised counterparts, which validates the effectiveness of the proposed contrastive framework with adaptive augmentation.
