Questions & Answers

Q: What is Torch and how is it different from other deep learning packages?

Torch is an open-source deep learning package that is popular for its versatility. It differs from packages like scikit-learn in terms of coding style and functionality, providing more flexibility for complex deep learning tasks.

Q: What is the purpose of the NN module in Torch?

The NN module is a key component in Torch that helps in setting up the hidden layers of a neural network. It allows for easy specification of loss functions and plays a crucial role in defining the network architecture.

Q: How are dataset types in Torch different from traditional numpy arrays?

Torch uses tensor datasets, which are specifically designed to handle data for deep learning models. These datasets are formatted to work with mini-batch training paradigms and have additional features for handling complex data processing.

Q: How does PyTorch Lightning aid in fitting deep learning models?

PyTorch Lightning is a helper package that simplifies the process of fitting deep learning models in Torch. It provides common patterns and functionality, such as a trainer class that encapsulates the process of training a model with specified data and network architecture.
