Check the two sentences either side of the subtitle "Taguchi's use of loss functions". Duplication. Far too many articles here are updated/changed line by line, without reference to readers or readability. Fact is, at least half the articles contain gross duplications of text, along with some having self-contradictory texts. Micro-writing without the macro-attention.
