Graph Neural Networks: A Review of Methods and Applications
Adaptive Graph Encoder for Attributed Graph Embedding
Experimental results show that AGE consistently outperforms state-of-the-art graph embedding methods considerably on node clustering and link prediction tasks, and the proposed Adaptive Graph Encoder employs an adaptive encoder that iteratively strengthens the filtered features for better node embeddings.

Exploring the Universal Vulnerability of Prompt-based Learning Paradigm
This paper explores the universal vulnerability of the prompt-based learning paradigm by injecting backdoor triggers or searching for adversarial triggers on pretrained language models using only plain text, and proposes a potential solution to mitigate the attack methods.
A Roadmap for Big Model
This paper discusses not only the BM technologies themselves but also the prerequisites for BM training and applications with BMs, dividing the BM review into four parts: Resource, Models, Key Technologies and Application.

The Markov-chain model and relevant analysis are presented for developing an efficient technique for handling conformal dielectrics in the floating random walk based capacitance extraction and two approaches reducing the computational cost of a domain decomposition based power-grid solver are presented.
Evaluating Modules in Graph Contrastive Learning
A set of module-level guidelines for GCL are proposed, e.g., simple samplers from LINE and DeepWalk are strong and robust; an MLP encoder associated with Sum readout could achieve competitive performance on graph classification.
