100 ChatGPT terms explained :

1. Natural Language Processing (NLP): This is the field of study that focuses on the interaction between computers and humans through natural language. The goal of NLP is to read, decipher, understand, and make sense of human language in a valuable way.
2. Artificial Intelligence (AI): AI refers to the simulation of human intelligence in machines that are programmed to think like humans and mimic their actions.
3. Machine Learning (ML): ML is a type of AI that provides systems the ability to automatically learn and improve from experience without being explicitly programmed.
4. Transformers: This is a type of ML model introduced in a paper titled “Attention is All You Need”. Transformers have been particularly effective in NLP tasks, and the GPT models (including ChatGPT) are based on the Transformer architecture.
5. Attention Mechanism: In the context of ML, attention mechanisms help models focus on specific aspects of the input data. They are a key part of Transformer models.
6. Fine-tuning: This is a process of taking a pre-trained model (like GPT) and training it further on a specific task. In the case of ChatGPT, it’s fine-tuned on a dataset of conversations.
7. Tokenization: In NLP, tokenization is the process of breaking down text into words, phrases, symbols, or other meaningful elements called tokens.
8. Sequence-to-Sequence Models: These are types of ML models that transform an input sequence into an output sequence. ChatGPT can be viewed as a kind of sequence-to-sequence model, where the input sequence is a conversation history and the output sequence is the model’s response.
9. Function Calling: In the context of programming, a function call is the process of invoking a function that has been previously defined. In the context of AI like ChatGPT, function calling can refer to using the model’s “generate” or “complete” functions to produce a response.
10. API: An API, or Application Programming Interface, is a set of rules and protocols for building and interacting with software applications. OpenAI provides an API that developers can use to interact with ChatGPT.
11. Prompt Engineering: This refers to the practice of crafting effective prompts to get the desired output from language models like GPT.
