PyTorch’s autograd system automatically computes gradients for tensor operations, enabling efficient backpropagation. It creates a dynamic computation graph, meaning that the graph is built on-the-fly as operations are performed, which…

Can you explain the concept of gradient descent and how it is used in training machine learning models?
Gradient descent is an optimization algorithm used to minimize the loss function in machine learning models. It works by iteratively adjusting model parameters in the opposite direction of the gradient…

What is the difference between batch gradient descent stochastic gradient descent and mini-batch gradient descent?
Batch GD computes gradients on the entire dataset — slow but stable. Stochastic GD (SGD) computes gradients on one example — fast but noisy. Mini-batch GD computes on a subset…
