This repository contains an implementation of a Transformer-based model and fine-tuned GPT-2 for an automated customer service chatbot using the Ubuntu Dialogue Corpus. The Transformer notebook includes data preprocessing with NLTK, model architecture design, and training using TensorFlow, while the GPT-2 notebook emphasizes data preparation, fine-tuning, and saving the enhanced model using Transformers for improved conversational performance.
- Load and preprocess data: Load the Ubuntu Dialogue Corpus and clean the text.
- Clean and tokenize text: Apply text preprocessing techniques and tokenize the text.
- Prepare input and target sequences for model training: Format the data for training the model.
- Define Transformer model architecture: Include Encoder and Decoder components.
- Implement attention mechanisms and other components: Ensure the model utilizes effective attention mechanisms.
- Train the model: Train the Transformer model on the preprocessed data.
- Validate and test the model: Evaluate the model's performance using validation and test sets.
- Integrate the trained model into a chatbot application: Build a functional chatbot using the trained model.
- Evaluate the chatbot's performance: Assess how well the chatbot performs on test data.
- Refine and improve the model: Use feedback to enhance the model's accuracy and functionality.
- Ongoing improvements: Continuously update and improve the chatbot's performance and features.
This section describes how to fine-tune the GPT-2 model on the Ubuntu Dialogue Corpus.
The fine-tuning notebook includes the following steps:
- Setup and Installation: Install necessary libraries (
transformers
,datasets
). - Load and Preprocess Data: Load the dataset and apply preprocessing steps such as cleaning and tokenization.
- Prepare Your Dataset: Convert the dataset into the format required for training GPT-2.
- Fine-Tune: Train GPT-2 on the preprocessed data.
- Save the Fine-Tuned Model: Save the model and tokenizer after fine-tuning.
