Tokenformer: Rethinking Transformer Scaling with Tokenized Model Parameters
Motivation It’s hard to imagine AI today without Transformers. These models are the backbone architecture behind large language models that have revolutionized AI. Their influence, however, is not limited to natural language processing. Transformers are also crucial in other domains, such as computer vision, where Vision Transformers (ViT) play a significant role. As we advance,…

Generative Reward Models: Merging the Power of RLHF and RLAIF for Smarter AI
Introduction In recent years, we’ve witnessed tremendous progress in AI, primarily due to the rise of large language models (LLMs) such as LLaMA-3.1. To further enhance LLM capabilities, extensive research focuses on improving their training processes. In this post, we review a recent research paper by Stanford University and SynthLabs that suggests a potential improvement, which may significantly advance AI. The paper is titled “Generative Reward Models”, authored by some of the same individuals behind the widely-used DPO method. LLM Training Process Before diving to Generative Reward Models (GenRMs), let’s do a quick recap for how large language models are trained. Pre-training Stage LLMs are first pre-trained on huge amount of text, to learn general purpose knowledge. This step helps the LLM to be good at predicting the next token in a…
