Q2. Hyper parameters of different DL algos.
Ans. 
Hyperparameters are settings that are external to the model and are used to control the learning process of deep learning algorithms.
• Hyperparameters for neural networks include learning rate, batch size, number of layers, number of neurons per layer, activation functions, and dropout rate.

• For example, in a convolutional neural network, hyperparameters may include filter size, stride, and padding.

• Hyperparameters can be ...read more
