Why Do Machine Learning Practitioners Still Use Manual Tuning? A Qualitative Study
[article]
2022
arXiv
pre-print
Preserved Fulltext
Nonetheless, machine learning (ML) practitioners (e.g., engineers, scientists) mostly apply less advanced HPO methods, which can increase resource consumption during HPO or lead to underoptimized ML models ...
Because qualitative research is most suitable to uncover such reasons and find potential explanations for them, we conducted semi-structured interviews to explain why practitioners choose different HPO ...
CONCLUSIONS, LIMITATIONS, AND FUTURE WORK Conclusions We reported on a qualitative study on the reasons why practitioners prefer different HPO methods. ...
