Question

____________ function is used as a mapping function for classification problem.

Answer 1

We may use Sigmoid function as a mapping function for classification problem.

• Sigmoid function is a logistic function that is characterized by a 'S' shaped curve.
• In machine learning, the 'classification problem' is a type of supervised learning problem. Here, the input value is segregated into various discrete classes.

Hope it helps.

Answer 2

Sigmoid function is used as a mapping function for the classification problem, so Sigmoid is the correct answer for the above question.

SIgmoid functions are highly used in the neural networks.

Sigmoid functions have the biggest benefit of utilizing the derivatives to learn the weights of the neural network easily. Hope it helps.
