Time-MoE is a library/framework for training and deploying time series foundation models using a Mixture-of-Experts (MoE) architecture. It provides tools for training the TimeMoE model from scratch or fine-tuning pretrained versions, evaluating on benchmark datasets, and generating forecasts. The codebase is organized into modules for models, datasets, training utilities, and I/O operations, with a clear separation of concerns. Key features include efficient handling of large sequential datasets via sharded binary files, a custom MoE layer with load balancing loss, and integration with Hugging Face Transformers for model management and generation.
