" by Francesco Bertolotti is garnering attention for its claimed "quite substantial improvement" in manufacturing optimization. The paper, identified via an arXiv link shared by Bertolotti on social media, outlines a novel pipeline for integrating Explainable Artificial Intelligence (XAI) with Lean Manufacturing principles.Lean Manufacturing, a methodology originating from the Toyota Production System, focuses on minimizing waste and maximizing efficiency through principles such as defining value, mapping the value stream, creating continuous flow, establishing a pull system, and pursuing perfection. The integration of AI, particularly XAI, is seen as a critical step in advancing these principles by providing transparency and interpretability to complex AI-driven decisions within production environments.The paper, available on arXiv under the identifier 2507.08649, details a pipeline designed to enhance traditional Lean methodologies with the predictive and analytical power of AI, while ensuring that the AI's recommendations are understandable and actionable by human operators. According to the tweet from Francesco Bertolotti, "The author obtained quite substantial improvement with their pipeline," suggesting significant advancements in operational efficiency or waste reduction.However, the tweet also highlighted a critical challenge for the research community: "the link to the code and data is not working." This issue points to a broader "reproducibility crisis" in artificial intelligence research, where the inability to access or run the underlying code and datasets hinders independent verification of results. Accessible code and data are crucial for other researchers to replicate findings, validate claims, and build upon existing work, fostering scientific progress and trust in AI advancements.The reported improvements from the LEANxAI pipeline suggest a promising direction for the future of smart manufacturing, where AI not only optimizes processes but also explains its reasoning. For the full impact of such research to be realized, and for the community to verify and expand upon these findings, the availability of functional code and data remains paramount. The incident underscores the ongoing need for robust open science practices within the AI and manufacturing research domains.
