It's not magic. It amazes me how many "data scientists" can't explain the basic mathematics behind their modelling. If the outcome of algorithm/model can't be explained by its regulators then it shouldn't be making any decisions of any significance or importance to human lives. When engineers fail to address cracking in a bridge and people die when it falls, humans are held to account and explain why this decision was so. If machine learning statistical models can't do the same, they better not be used to scan any bridges for structural cracking where I live and vote.
