A Brief History 1.Early 1990s: Ferdinand de Saussure, a Swiss linguistics professor, concepts of language as systems Created through the relationships and differences within language elements 2. 1916: Two of Saussure’s colleagues, publish “Cours de Linguistique Générale,” Structuralist approach to linguistics and influences later fields, including computer science 3. 1950: Alan Turing publishes, a paper proposing Machine can converse indistinguishably from a human 4. 1952: Hodgkin-Huxley model of neuronal activity, furthers the understanding of how the brain processes information Contributing to the development of artificial intelligence (AI) and natural language processing (NLP) History of Natural Language Processing

- 15. Large Language Model Whatis Large Language Model? (LLM) is a deep learning algorithm that can perform a variety of natural language processing (NLP) tasks.
- 16. Large Language Model Differencebetween LLMs and Generative AI Generative AI is an umbrella term that refers to artificial intelligence models that have the capability to generate content. Generative AI can generate text, code, images, video, and music. Examples of generative AI include Midjourney, DALL-E, and ChatGPT. Large language models are a type of generative AI that are trained on text and produce textual content. ChatGPT is a popular example of generative text AI. ※ All large language models are generative AI

- 19. Large Language Model PopularLarge Language Models •PaLM: Google's Pathways Language Model (PaLM) is a transformer language model capable of common- sense and arithmetic reasoning, joke explanation, code generation, and translation. •BERT: The Bidirectional Encoder Representations from Transformers (BERT) language model was also developed at Google. It is a transformer-based model that can understand natural language and answer questions. • XLNet: A permutation language model, XLNet generated output predictions in a random order, which distinguishes it from BERT. It assesses the pattern of tokens encoded and then predicts tokens in random order, instead of a sequential order. GPT: Generative pre-trained transformers are perhaps the best-known large language models. Developed by OpenAI, GPT is a popular foundational model whose numbered iterations are improvements on their predecessors (GPT-3, GPT-4, etc.). Google’s Gemini, Anthropic’s Claude 3.5 Sonnet…
