Upcycling: A Smart Initialization for Mixture of Experts (MoE) After reading the paper on upcycling large language models, I realized that this technique is more than just a clever way to extend model capacity; it can be viewed as a powerful initialization strategy for MoE models. By copying weights from pre-trained dense models, upcycling sets up the MoE architecture with a strong foundation, ensuring that the model benefits from prior training without starting from scratch. This method optimizes efficiency and accelerates convergence, making it an attractive approach for scaling models without the massive compute costs typically associated with MoE models. Upcycling truly showcases the potential of smart initialization. https://arxiv.org/abs/2410.07524
