Mastering Deep Learning with PyTorch: From Tensors to Advanced Neural Networks for LLMs

1. Introduction to Deep Learning and PyTorch

What is Deep Learning?

Deep learning is a subfield of machine learning inspired by the structure and function of the human brain’s neural networks. Instead of explicit programming, deep learning models learn from vast amounts of data, automatically discovering intricate patterns and representations. These models are characterized by their “deep” architecture, consisting of multiple layers, which allows them to extract hierarchical features from raw data. From recognizing objects in images to understanding human language and generating creative content, deep learning has revolutionized numerous domains.
