     - "learning_rate": The learning rate specifies the speed of learning. A higher value ensures fast learning (the optimiser may diverge) and a lower value causes slow learning (may not reach the optimum). This parameter should be optimised as well.
     - "activation_recurrent": Activations are mathematical functions to transform input into output. This takes the name of an activation function from the list of Keras activations (https://keras.io/activations/) for recurrent layers.
     - "activation_output": This takes the activation for transforming the input of the last layer to the output of the neural network. It is also taken from Keras activations (https://keras.io/activations/).
-    - "loss_type": This is also a mathematical function which computes the error between true and predicted outputs. An optimizer uses this loss function to compute error and minimize it. It is taken from the list of Keras optimisers (https://keras.io/optimizers/).
