Deep Learning

Transformers have revolutionized natural language processing (NLP) and power today’s largest language models (LLMs) like GPT and BERT. This zero-to-hero tutorial takes developers from core concepts to practical implementation, covering architecture, why they dominate, hands-on Python code with Hugging Face, pitfalls, training strategies, and deployment tips. What Are Transformers? Transformers are neural network architectures designed for sequence data, introduced in the 2017 paper “Attention is All You Need”. Unlike recurrent models (RNNs/LSTMs), Transformers process entire sequences in parallel using self-attention mechanisms, eliminating sequential dependencies for faster training on long-range contexts[1][3]. ...

Modern large language models (LLMs) like GPT-4, Llama, and Claude look magical—but they are built on concepts that have matured over decades: neural networks, gradient descent, and clever architectural choices. This tutorial walks you step by step from classic neural networks all the way to LLMs. You’ll see how each idea builds on the previous one, and you’ll get practical code examples along the way.

In 2017, a team at Google published a paper that would fundamentally reshape the landscape of machine learning. “Attention Is All You Need” by Vaswani et al. introduced the Transformer architecture—a bold departure from the recurrent and convolutional approaches that had dominated sequence modeling for years. The paper’s central thesis was radical: you don’t need recurrence or convolution at all. Just attention mechanisms and feed-forward networks are sufficient to achieve state-of-the-art results in sequence-to-sequence tasks. ...
