WebDec 17, 2024 · A Concrete Example. Suppose we have K = 3 classes, and our label belongs to the 1st class. Let [a, b, c] be our logit vector.If we do not use label smoothing, the label vector is the one-hot encoded vector [1, 0, 0]. Our model will make a ≫ b and a ≫ c.For example, applying softmax to the logit vector [10, 0, 0] gives [0.9999, 0, 0] rounded to 4 …
