Benchmarking a transformer-FREE model for ad-hoc retrieval
Tiago Almeida, S{\'e}rgio Matos
Transformer-based {``}behemoths{''} have grown in popularity, as well as structurally, shattering multiple NLP benchmarks along the way. However, their real-world usability remains a question. In this work, we empirically assess the feasibility of applying transformer-based models in real-world ad-hoc retrieval applications by comparison to a {``}greener and more sustainable{''} alternative, comprising only 620 trainable parameters. We present an analysis of their efficacy and efficiency and show that considering limited computational resources, the lighter model running on the CPU achieves a 3 to 20 times speedup in training and 7 to 47 times in inference while maintaining a comparable retrieval performance. Code to reproduce the efficiency experiments is available on {``}https://github.com/bioinformatics-ua/EACL2021-reproducibility/{``}.
