Manifold-Aware vs. Euclidean Dense Retrieval in Cross-Lingual Benchmark Efficiency

Abstract

Abstract: This report synthesises findings from 4 peer-reviewed papers addressing the following research question: What is the computational efficiency trade-off between manifold-aware and Euclidean-based dense retrieval models when evaluating cross-lingual robustness on benchmarks like XLENT or mTEC. Cross-lingual representations of words enable us to reason about word meaning in multilingual contexts and are a key facilitator of cross-lingual transfer when developing natural language processing models for low-resource languages. In this survey, we provide a comprehensive. 6 claims were extracted from source literature; 6 were independently verified against retrieved documents. An automated multi-reviewer quality assessment produced a score of 8.3/10. This report is a machine-generated literature synthesis and does not constitute original research.
