The podcast explores how artificial intelligence can understand and process natural language, focusing on tokenization, n-grams, and sentiment analysis. It introduces tokenization methods, including word-based, character-based, and sub-word tokenization, and examines the use of n-grams to predict the next word in a sequence. The discussion covers sentiment analysis, using restaurant reviews to illustrate how computers can classify text as positive or negative based on word associations and probabilities. The podcast further discusses neural networks, word embeddings, and recurrent neural networks to process sequences of text, highlighting the transformer architecture and the concept of attention. The goal is to enable AI to communicate using natural language by identifying relevant parts of a sequence and updating word meanings.
