Unreproducible Research is Reproducible

June 10, 2019

Abstract

The apparent contradiction in the title is a word- play on the different meanings attributed to the word reproducible across different scientific fields. What we imply is that unreproducible findings can be built upon reproducible methods. With- out denying the importance of facilitating the re- production of methods, we deem important to reassert that reproduction of findings is a funda- mental step of the scientific inquiry. We argue that the commendable quest towards easy deter- ministic reproducibility of methods and numerical results should not have us forget the even more im- portant necessity of ensuring the reproducibility of empirical findings and conclusions by properly accounting for essential sources of variations. We provide experiments to exemplify the brittleness of current common practice in the evaluation of models in the field of deep learning, showing that even if the results could be reproduced, a slightly different experiment would not support the find- ings. We hope to help clarify the distinction be- tween exploratory and empirical research in the field of deep learning and believe more energy should be devoted to proper empirical research in our community. This work is an attempt to promote the use of more rigorous and diversified methodologies. It is not an attempt to impose a new methodology and it is not a critique on the nature of exploratory research.
