A "Pathway" in the context of machine learning refers to the specific route or method that a model takes to process information and make decisions. It involves the flow of data through various layers and nodes in a neural network, allowing the model to learn patterns and relationships within the data. A "Language Model" is a type of artificial intelligence designed to understand and generate human language. It predicts the likelihood of a sequence of words, enabling applications like text generation, translation, and conversational agents. Examples of language models include GPT-3 and BERT, which are widely used in natural language processing tasks.
