Hi @Anand_Kumar3

I suppose there might be a bit confusion to your understanding,

Hello, Gated recurrent unit is a modification to the RNN hidden layer which makes it much better at capturing long-range connections and helps a lot with the vanishing gradient problems. the c^t equation in the image the activation function applied to the parameter W_a times the activations for a previous time sediment the current input and then plus the bias. GRU unit is going to have a new variable called C, which stands for cell memory. What the memory cell do is it will provide a bit of m…

Read through the comment which explain when gamma u is 0, the initial value is updated and not the new one.

Also the significance of tanh provides a nonlinear response which can capture higher-level patterns or features in the input data when comes to training a neural network.
