alleryStart learning →The sigmoid function squashes its input to which interval?
AThe interval (-∞, ∞)
BThe interval [0, ∞)
CThe interval (0, 1)
DThe interval (-1, 1)
Answer & Solution
Correct answer: C. The interval (0, 1)
sigmoid(x) = 1/(1 + exp(-x)) maps the real line into (0, 1).
Often used for binary-classification outputs interpreted as probabilities.
