AI Training Datasets
The realm of Artificial Intelligence (AI) is complex and intricate, and this complexity manifests acutely in foundation models. Understanding how foundation models work involves delving into their fundamental technologies, the process of pre-training and fine-tuning, and the scale and data used for their training.
Foundation models, especially those involved with natural language processing tasks, commonly rely on a deep learning architecture known as Transformers. The Transformer model, introduced in the paper “Attention is All You Need” by Vaswani et al., has since been at the core of several influential foundation models, such as GPT-3 and BERT.
The Transformer model’s novelty and effectiveness come from its self-attention mechanism. Self-Attention allows the model to weigh and consider different words in the context when producing an output. For example, in the sentence “Jane is going to school because she has a test,” the self-attention mechanism enables the model to understand that “she” refers to “Jane”. This ability to understand the relationships between words in a sentence is crucial for generating coherent and contextually accurate text.
Foundation Models go through two main phases during their training: pre-training and fine-tuning.
The effectiveness of foundation models is closely linked to their scale, both in terms of the model size (number of parameters) and the amount of data they are trained on.
