Can they be linear regression. In short can we use NN only in classification problems?

Hello @kanishk_rastogi

You may use sigmoid as the activation in the output layer for classification problems, or linear as the activation in the output layer for regression problems.

Yes. There are several activation functions that you can use, sigmoid is one of them, you can use linear for regression problems and softmax for multiple outcomes.

Let me know if this answers your question
