How do GRU's work with Keras? Explain with an example

GRU stands for Gated Recurrent Units. It was created as the solution to short-term Memory. It is very similar to LSTM its internal mechanism is controlled by gates and they regulate the flow of information. GRU uses a hidden state instead of a cell state to transfer information, it only has two gates update gate and the reset gate.

Step 1- Importing Libraries

import keras from keras.models import Sequential from keras.layers import GRU import numpy as np

Step 2- Define the model.

We will define the model and Add a GRU layer to it.

model = Sequential() model.add(GRU(1, input_shape=(20,1))) model.compile(optimizer='adam', loss='mse')

Step 3- We will define a sample array to run in the model.

We will define the arrays and run them in the model.

# input time steps y = np.array([[1, 2, 3, 4, 5, 6, 7, 8, 9, 10],[9, 8, 7, 6, 5, 4, 3, 2, 1, 0]]).reshape((1,20,1)) # make and show prediction print(model.predict(y))
