## Description

Lag-llama is a probabilistic machine learning foundation model designed for time series forecasting. It generates predictive distributions and uncertainty bounds for sequential data across arbitrary frequencies by leveraging pre-trained foundational weights.

The system supports zero-shot transfer inference, allowing it to predict future values on entirely new and unseen datasets without requiring prior retraining. It achieves this by combining generalized representations from foundational training with adjustable context lengths, where historical context lengths and lagged feature values feed directly into the model inputs during iterative autoregressive predictions.

Additionally, the framework provides capabilities for foundation model fine-tuning. Users can adapt pre-trained weights and adjust forecasting models on specialized datasets using targeted hyperparameters and validation splits to optimize domain-specific predictive accuracy.
