💡Generative AI

Generative AI refers to the branch of artificial intelligence that focuses on creating or generating new data based on patterns learned from a training sample. In the context of the video, it is used to describe the technology behind models like GPT and large language models (LLMs), which can generate text, images, audio, and more. The video emphasizes the capability of Generative AI to produce unstructured data types, highlighting its role in various applications.

💡Large Language Models (LLMs)

Large Language Models, or LLMs, are a type of generative AI model specifically designed for natural language processing tasks. They are trained on vast amounts of text data, enabling them to understand and generate human-like text. The video underscores the power of LLMs in performing a variety of language-related tasks, such as text generation, translation, summarization, and even coding, due to their extensive training data and complex neural network architecture.

💡Transformer Architecture

The Transformer architecture is a deep learning framework introduced in the paper 'Attention Is All You Need'. It revolutionized the field of NLP by effectively handling sequences of data, such as sentences, through self-attention mechanisms. Unlike RNNs and LSTMs, Transformers do not process data sequentially but in parallel, which significantly speeds up training and inference. The video explains that the Transformer architecture is the foundation of modern LLMs, enabling them to understand complex relationships within text data and generate coherent responses.

💡Prompt Engineering

Prompt engineering is the process of designing and refining the input prompts provided to generative AI models, particularly LLMs, to elicit the desired output. The video emphasizes the importance of this process in guiding the model to perform specific tasks effectively. It involves carefully crafting the input text to lead the model towards a particular response, which can be critical in applications like chatbots, content generation, and more.

💡Unsupervised Learning

Unsupervised learning is a type of machine learning where the model learns patterns and structures from a dataset without explicit guidance or labeled responses. In the video, it is mentioned as the first step in training LLMs, where the model is exposed to a large corpus of text data to identify and learn language patterns, structures, and relationships without being told what each piece of data 'means' or what the correct output should be.

💡Supervised Fine-Tuning

Supervised fine-tuning is a process in machine learning where a pre-trained model is further trained on a smaller, more specific dataset to perform a particular task. In the context of the video, this process is used after unsupervised learning to adapt the LLM to specific tasks such as question-answering, text summarization, or translation. The model is provided with labeled data, which includes inputs and desired outputs, allowing it to make more targeted and accurate predictions.

💡Reinforcement Learning

Reinforcement learning is a type of machine learning where an agent learns to make decisions by interacting with an environment and receiving feedback in the form of rewards or penalties. In the video, it is mentioned as a part of the training process for certain LLMs, like ChatGPT, where the model learns to generate responses by taking actions and receiving feedback that either encourages or discourages certain behaviors.


OpenAI is an artificial intelligence research lab that focuses on creating and promoting friendly AI to ensure that artificial general intelligence (AGI) benefits all of humanity. In the video, OpenAI is noted as the creator of the GPT (Generative Pre-trained Transformer) models, which are a series of powerful LLMs capable of generating human-like text across a range of tasks.

💡Hugging Face

Hugging Face is an open-source platform focused on providing tools and models for natural language processing (NLP). In the video, it is mentioned as a source for various open-source LLMs and as a platform where developers can find pre-trained models, utilities, and contribute to the NLP community. The platform hosts a model hub where different LLMs can be explored and used for diverse NLP tasks.

💡Transfer Learning

Transfer learning is a machine learning technique where a model trained on one task is reused as the starting point for a model on another related task. It allows the new model to leverage the knowledge gained from the initial task to improve its performance on the subsequent task. In the video, transfer learning is discussed in the context of NLP, where an LLM trained on a large corpus of data can be fine-tuned for specific tasks, thus benefiting from the patterns and structures learned during the initial training phase.
