Researcher struggles to train GPT-like model on non-language data

A researcher is encountering difficulties training a GPT-like transformer model on a non-language dataset. Despite using standard hyperparameters like AdamW optimizer and a 1e-3 learning rate, the model fails to exhibit basic auto-regressive behavior and often gets stuck generating a single token. The researcher is seeking advice on potential tricks or insights into training such models, as it appears to be a challenging task. AI

IMPACT Highlights potential challenges in adapting transformer architectures to novel data types, indicating areas for further research.
