🧠 Quiz: What is the fundamental data structure for all computations in PyTorch?

A) NumPy Array
B) PyTorch Tensor
C) Pandas DataFrame
D) Python List

✅ Correct answer: B

Explanation: PyTorch Tensors are multi-dimensional arrays, similar to NumPy arrays, but with the added ability to run on GPUs for accelerated computation and support for automatic differentiation, which is crucial for neural network training.

❔ Interview question

What is the purpose of a pooling layer in a Convolutional Neural Network (CNN)?

Answer: A pooling layer (like Max Pooling or Average Pooling) is used to progressively reduce the spatial size (width and height) of the feature maps. This serves two main purposes: 1) It reduces the number of parameters and computational complexity, which helps to control overfitting. 2) It introduces a degree of translation invariance, meaning the network becomes more robust to small shifts and distortions in the position of features in the input image.
