With the advent of industry 4.0, advancements in artificial intelligence (AI) have become vital to helping with industry efficiency and performance. Recently, a group of researchers surveyed the existing AI and explainable AI (XAI) based methods used in Industry 4.0 highlighting the need for XAI-based methods to help build efficient smart cities, factories, healthcare, and human-computer interactions. The very first industrial revolution historically kicked off with the introduction of steam- and water-powered technology.
