Correct Answer is (ii)All the options
Recurrent Neural Networks (RNNs) add an interesting twist to basic neural networks. A vanilla neural network takes in a fixed size vector as input which limits its usage in situations that involve a ‘series’ type input with no predetermined size.
Gated Recurrent Unit
Gated Recurrent Unit (GRU) is LSTM with a forget gate.
It is used in sound, speech synthesis, and so on.
Image classification is one of the common applications of deep learning.
A convolutional neural network can be used to recognize images and label them automatically.
Deepnets (an optimized version of Deep Neural Networks) can be trained to recognize different objects within the same image.
