1. Intro

Graph Prompting challenges:

1. organize the graph prompt & how to insert it into origin Graph
2. reconcile the downsteam task to pretext tasks: 把node/edge level的统一为graph-level task
3. prompt initilization: meta-learning

2. Motivation

Ref the LLM’s “Pre-train，Prompt, Test”

If the pre-training tasks are similar,why not use the similar prompt strategy?

3. Method

3.1 Unify the tasks

使用图分类来统一下游的任务；使用图级别的对比学习（SSL）来预训练：【如 SimGRACE， GraphCL】；
