Identification of cognates across related languages is one of the primary
problems in historical linguistics. Automated cognate identification is helpful
for several downstream tasks including identifying sound correspondences,
proto-language reconstruction, phylogenetic classification, etc. Previous
state-of-the-art methods for cognate identification are mostly based on
distributions of phonemes computed across multilingual wordlists and make
little use of the cognacy labels that define links among cognate clusters. In
this paper, we present a transformer-based architecture inspired by
computational biology for the task of automated cognate detection. Beyond a
certain amount of supervision, this method performs better than the existing
methods, and shows steady improvement with further increase in supervision,
thereby proving the efficacy of utilizing the labeled information. We also
demonstrate that accepting multiple sequence alignments as input and having an
end-to-end architecture with link prediction head saves much computation time
while simultaneously yielding superior performance.

基于转换器的架构用于自动认知检测任务，在一定程度的监督下，该方法比现有方法表现更好，证明了利用标记信息的效果，并且通过接受多个序列对齐作为输入和具有链接预测头的端到端架构可以节省大量计算时间并同时产生更好的性能。
