🏃‍♂️ Training the Model

Original Transformer Training

After building the project, running main.cpp will train the model and save hyperparameters to the directory specified in config/transformer_config.json:

./transformer

Integrated Platform Training

The integrated platform automatically handles distributed training, data curation, and RLHF:

./integrated_platform_node --node-type full --node-id my_node

📝 Logging

• Original transformer: Logging to transformer.log in the build directory
• Integrated platform: Comprehensive logging with configurable levels and real-time monitoring

⚠️ Limitations

• The original model training uses a small dataset, so predictions may be sub-optimal
• Original transformer works with format: "I like to cook in the |kitchen" (where | is delimiter)
• Integrated platform requires network connectivity for distributed features
