Hello Everyone, Welcome to Codersarts!
In this blog, we’ll explore the step-by-step process of implementing a Transformer language model. Whether you're a student working on assignments or a developer looking to deepen your understanding, this guide will walk you through the key concepts and hands-on tasks involved in building Transformer-based models.
We've structured the content to function like assignment tasks with clear instructions, enabling you to implement and test the model as a proof of concept. This approach not only ensures you gain practical experience but also helps reinforce your understanding of self-attention mechanisms, multi-head attention, and positional encoding — all critical components of Transformer architectures.
By the end of this tutorial, you’ll be equipped with the knowledge to:
Build a Transformer model from scratch using frameworks like PyTorch or TensorFlow.
Train the model on language modeling tasks with appropriate datasets.
Apply fine-tuning techniques to improve model performance.
Solve common challenges related to training dynamics, attention issues, and GPU setup.
So, whether you’re here for assignment help, troubleshooting advice, or project support, this blog will provide everything you need to succeed in Transformer-based NLP tasks.
This assignment will help you gain hands-on experience with Transformer models by implementing character-based Transformers for sequence prediction and language modeling tasks. You will build a simplified Transformer from scratch, experiment with attention mechanisms, and implement language modeling techniques using Python and PyTorch.
Goals
Understand self-attention mechanisms in Transformers.
Implement a basic Transformer encoder without relying on pre-built libraries.
Use transformer-based architectures for language modeling tasks.
Evaluate the perplexity and accuracy of the implemented model.
Tools and Dataset
Use Python and PyTorch (latest versions).
The dataset is a character-based subset of Wikipedia’s first 100M characters, processed to use 27 character types.
Use the provided utils.py and lettercounting.py files for setting up tasks.
Part 1: Build a Transformer Encoder (50 points)
Implement a simplified Transformer encoder from scratch for a character-sequence prediction task. Your task is to predict how many times each character in a sequence has occurred previously. You will learn to build a single-head attention mechanism and residual connections.
Steps to Implement:
Prepare the Transformer Layer:
Build query, key, and value matrices using linear layers.
Use matrix multiplication for self-attention.
Add residual connections and apply non-linearity (ReLU).
Train the Transformer Encoder:
Train the model using a 20-character sequence input.
Use cross-entropy loss to compute the prediction loss for all positions in the sequence.
Achieve at least 85% accuracy on the task.
Run the Model:
Use the following command to execute your implementation:
python letter_counting.py --task BEFOREAFTERPart 2: Transformer for Language Modeling (50 points)
In this part, you will extend the Transformer architecture to build a language model capable of predicting the next character in a sequence.
Implementation Steps:
Use Positional Encodings:
Implement positional embeddings to handle sequence ordering.
Use causal masking to prevent tokens from attending to future tokens.
Train the Language Model:
Train the model on the first 100,000 characters of Wikipedia.
Evaluate the model on the development set and achieve a perplexity below 7.
Run the Model:Use the following command to train the language model:
python lm.py
Optimization Tip:Implement multi-head attention to improve model performance and explore the attention patterns to understand how your model makes predictions.
Deliverables and Submission Guidelines
Submit your code files for Parts 1 and 2.
Your implementation should pass sanity checks using the following commands:
python letter_counting.py
python lm.py --model NEURAL
