Reproducible Pattern Recognition Research: The Case of Optimistic SSL Machine Learning

In this paper, we discuss the approaches we took and trade-offs involved in making a paper on a conceptual topic in pattern recognition research fully reproducible. We discuss our definition of reproducibility, the tools used, how the analysis was set up, show some examples of alternative analyses the code enables and discuss our views on reproducibility.

State of the Art: Reproducibility in Artificial Intelligence

AAAI Conferences

Background: Research results in artificial intelligence (AI) are criticized for not being reproducible. Objective: To quantify the state of reproducibility of empirical AI research using six reproducibility metrics measuring three different degrees of reproducibility. Hypotheses: 1) AI research is not documented well enough to reproduce the reported results. 2) Documentation practices have improved over time. Method: The literature is reviewed and a set of variables that should be documented to enable reproducibility are grouped into three factors: Experiment, Data and Method. The metrics describe how well the factors have been documented for a paper. A total of 400 research papers from the conference series IJCAI and AAAI have been surveyed using the metrics. Findings: None of the papers document all of the variables. The metrics show that between 20% and 30% of the variables for each factor are documented. One of the metrics show statistically significant increase over time while the others show no change. Interpretation: The reproducibility scores decrease with in- creased documentation requirements. Improvement over time is found. Conclusion: Both hypotheses are supported.

Estimating Reproducibility of AI Research - Amsterdam Data Science


Being able to reproduce research is a key aspect of creating knowledge. If a study can be reproduced by another lab then the validity of the findings are confirmed. This is particularly important in AI research with questions around explainable and trustworthy AI. There are a number of different ways to refer to reproducibility, in this piece we are actually referring to replicability using the standard ACM definition. It refers to research that reuses the data and/or analysis to hopefully get the same results.

Reproducibility, Replicability, and Data Science - KDnuggets


Reproducibility and replicability are cornerstones of scientific inquiry. Although there is some debate on terminology and definitions, if something is reproducible, it means that the same result can be recreated by following a specific set of steps with a consistent dataset. If something is replicable, it means that the same conclusions or outcomes can be found using slightly different data or processes. Without reproducibility, process and findings can't be verified. Without replicability, it is difficult to trust the findings of a single study.

Improving Reproducibility in Machine Learning Research (A Report from the NeurIPS 2019 Reproducibility Program) Machine Learning

One of the challenges in machine learning research is to ensure that presented and published results are sound and reliable. Reproducibility, that is obtaining similar results as presented in a paper or talk, using the same code and data (when available), is a necessary step to verify the reliability of research findings. Reproducibility is also an important step to promote open and accessible research, thereby allowing the scientific community to quickly integrate new findings and convert ideas to practice. Reproducibility also promotes the use of robust experimental workflows, which potentially reduce unintentional errors. In 2019, the Neural Information Processing Systems (NeurIPS) conference, the premier international conference for research in machine learning, introduced a reproducibility program, designed to improve the standards across the community for how we conduct, communicate, and evaluate machine learning research. The program contained three components: a code submission policy, a community-wide reproducibility challenge, and the inclusion of the Machine Learning Reproducibility checklist as part of the paper submission process. In this paper, we describe each of these components, how it was deployed, as well as what we were able to learn from this initiative.
