Graph contrastive learning (GCL) has emerged as a dominant technique for graph representation which maximizes the mutual information between paired augmentations that share same semantics. Unfortunately, it is difficult to preserve semantics well during in view of diverse nature data. Currently, data GCL broadly fall into three unsatisfactory ways. First, can be manually picked per dataset by trial-and-errors. Second, selected via cumbersome search. Third, obtained with expensive domain...

From CNN, RNN, to ViT, we have witnessed remarkable advancements in video prediction, incorporating auxiliary inputs, elaborate neural architectures, and sophisticated training strategies. We admire these progresses but are confused about the necessity: is there a simple method that can perform comparably well? This paper proposes SimVp, prediction model completely built upon CNN trained by MSE loss an end-to-end fashion. Without introducing any additional tricks complicated strategies,...

The method of importance map has been widely adopted in DNN-based lossy image compression to achieve bit allocation according the contents. However, insufficient bits non-important regions often leads severe distortion at low bpp (bits per pixel), which hampers development efficient content-weighted systems. This paper rethinks content-based by using Generative Adversarial Network (GAN) reconstruct regions. Moreover, multiscale pyramid decomposition is applied both encoder and discriminator...

Graph neural networks (GNNs) have been playing important roles in various graph-related tasks. However, most existing GNNs are based on the assumption of homophily, so they cannot be directly generalized to heterophily settings where connected nodes may different features and class labels. Moreover, real-world graphs often arise from highly entangled latent factors, but tend ignore this simply denote heterogeneous relations between as binary-valued homogeneous edges. In article, we propose a...

Graph Neural Network (GNN) has emerged as a predominant tool for graph data analysis. Despite their proliferation, the low-quality labels of many real-world graphs will undermine performance dramatically. Existing studies on learning neural networks with noisy mainly focus independent and thus cannot fully exploit structural information data. Currently, there are few robustness to graph-structured even if this problem is commonly seen in settings. To remedy deficiency, we propose <italic...
