  This paper details an empirical investigation into using Graph Contrastive
Learning (GCL) to generate mathematical equation representations, a critical
aspect of Mathematical Information Retrieval (MIR). Our findings reveal that
this simple approach consistently exceeds the performance of the current
leading formula retrieval model, TangentCFT. To support ongoing research and
development in this field, we have made our source code accessible to the
public at https://github.com/WangPeiSyuan/GCL-Formula-Retrieval/.
