Introduction¶
In the world of artificial intelligence and machine learning, one of the challenges organizations face is building domain-specific applications that truly reflect the terminology and intricacies of their business. While there are already powerful language models available, such as those provided by Amazon’s Bedrock, they are often trained on large amounts of publicly available data, making them less suitable for highly specialized domains.
To bridge this gap and enable language models to grasp the nuances of specific industries, continued pre-training has emerged as a valuable technique. Continued pre-training leverages vast sets of unlabeled data to further refine models and expose them to new, diverse information that goes beyond their original training. By engaging in continued pre-training using Amazon Bedrock, organizations can tailor these models to better understand the language and context of their own domain, ultimately improving their competency and effectiveness.
Understanding Continued Pre-Training¶
Continued pre-training is a process that involves further training language models on unlabeled data after their initial pre-training on publicly available datasets. This additional training process aims to refine and enhance the models’ ability to understand and generate language that is specific to a particular domain or industry.
The main advantage of continued pre-training is that it helps address the challenge of out-of-domain learning. Out-of-domain learning refers to situations where models struggle to comprehend or accurately generate language that is unique to a specialized domain, due to their exposure to predominantly diverse and general-purpose training data.
By introducing continued pre-training into the mix, organizations can significantly improve the models’ fine-tuning capabilities and expand their understanding of domain-specific language. Essentially, continued pre-training bridges the gap between general-purpose language models and highly specialized industries, making the models more precise and effective within specific business contexts.
