Pretraining a Generative AI Customer Support Model on X Data

In this section, we will pretrain a Hugging Face RobertaForCausalLM model to be a Generative AI customer support chat agent for X (former Twitter). RoBERTa is an encoder-only model. As such, it is mainly designed to understand and encode inputs. In Chapter 2, Getting Started with the Architecture of the Transformer Model, we saw how the encoder learns to understand and then sends the information to the decoder, generating content. However, in this section, we will use the Hugging Face functionality to adapt a RoBERTa model to run an autoregressive generative AI task. The experiment has limitations, but it shows the inner workings of content generation.The knowledge you acquired in this chapter through building a KantaiBERT from scratch will enable you to enjoy the ride!The generative model and dataset are free, making the exercise particularly interesting. With some work, domain-specific generative AI agents can help companies...
