Internal Covariate Shift refers to the phenomenon where the distribution of intermediate activations (the outputs of hidden layers) within a neural network changes during training. During the training of deep neural networks, the model’s parameters (weights and biases) are updated using optimization algorithms like gradient descent. …

1. What are some common activation functions used in deep learning, and how do they differ from each other? — Answer: Some common activation functions used in deep learning include the sigmoid, hyperbolic tangent (tanh), rectified linear unit (ReLU), and softmax functions. The sigmoid and tanh functions are both smooth and saturate as their input gets very large or small. The ReLU function is non-saturating and has a simple derivative…

During training, the objective is to find the optimal weights and biases (parameters) for the neural network that minimize the loss function. Gradient descent optimization is one of the most commonly used algorithms for training neural networks. The activation function impacts the gradient descent optimization algorithm by affecting the gradients…

Deep neural network training involves understanding exploding and vanishing gradients. Exploding gradients become large, causing divergence, while vanishing gradients lead to slow convergence. These affect training times, convergence, and model performance. Techniques like weight initialization, activation functions (e.g., ReLU), batch normalization, gradient clipping, and residual connections mitigate these issues.
