DAY - 1 | Introduction to Generative AI Community Course LIVE ! #genai #ineuron

The speaker begins by greeting the audience and asking for confirmation of audible and visible presence. They mention waiting for two more minutes before starting the session and give an overview of the agenda for the upcoming two weeks, focusing on generative AI. The speaker emphasizes the importance of audience engagement and interaction, asking for chat confirmations to ensure smooth session proceedings.

The speaker provides a detailed explanation of the session schedule, stating that it will be a community session focused on generative AI. They clarify that the sessions will occur daily from 3:00 to 5:00 PM and will cover a range of topics from basic to advanced levels. The speaker also introduces the concept of different types of applications that will be discussed and developed during the sessions.

The speaker guides the audience on how to access and enroll in the session's dashboard, which is free of charge. They mention that their team will share the link in the chat for ease of access. The dashboard serves as a hub for all session materials, including lectures, quizzes, and assignments. The speaker also introduces themselves and their expertise in data science, machine learning, and deep learning.

The speaker presents an overview of the curriculum, focusing on generative AI and large language models (LLMs). They discuss the structure of the course, starting with an introduction to generative AI and moving towards more complex topics such as open AI and its applications. The speaker emphasizes the importance of understanding the theoretical aspects and the practical implementation of these concepts.

The speaker outlines the technical prerequisites for the session, stating that a basic understanding of Python and machine learning is beneficial but not mandatory. They reassure the audience that all concepts will be explained during the sessions, and live implementations will be conducted. The speaker also highlights the potential benefits of the course for different types of learners, including those working in the industry, looking to switch careers, or freshers.

The speaker begins to delve into the introduction of generative AI and large language models, asking the audience about their prior knowledge and experience with these topics. They mention the use of a PowerPoint presentation to aid the explanation and indicate that they will use a blackboard for additional illustrations. The speaker aims to cover the roots of generative AI, beyond popular applications like ChatGPT and Google BERT.

The speaker starts from the basics of deep learning, explaining the different types of neural networks such as artificial neural networks (ANN), convolutional neural networks (CNN), and recurrent neural networks (RNN). They provide a brief overview of each network type and their applications. The speaker also introduces the concept of reinforcement learning and generative adversarial networks (GANs), setting the stage for a deeper discussion on generative AI.

The speaker elaborates on generative AI, defining it as a system that generates new data based on a training sample. They categorize generative AI into generative image models and generative language models, with the latter including large language models (LLMs). The speaker also discusses the transition from GANs to the popularity of LLMs in recent times and hints at the upcoming discussion on the history of transformers and the evolution of LLMs.

The speaker discusses the various tasks that generative models can perform, such as image to image generation, text to text generation, and image to text generation. They emphasize the versatility of LLMs in handling both homogeneous and heterogeneous tasks. The speaker also explains the concept of prompts and their importance in designing effective inputs for generative models.

The speaker clarifies the position of generative AI within the broader context of deep learning. They explain that generative AI is a subset of deep learning, which in turn is a subset of machine learning. The speaker uses a visual aid to illustrate this hierarchy and emphasizes that generative AI, including LLMs and GANs, is a part of the deep learning domain.

The speaker provides a timeline of the development of large language models (LLMs), starting from the basics of RNNs and LSTMs to the introduction of GRUs. They discuss the evolution of sequence to sequence mapping and the introduction of the encoder-decoder architecture. The speaker also highlights the breakthrough paper 'Attention Is All You Need', which introduced the Transformer architecture that forms the basis of modern LLMs.

The speaker contrasts generative and discriminative models, explaining that while discriminative models are trained on specific data for classification tasks, generative models learn to generate new data based on patterns identified in the training data. They outline the different training processes for these models, emphasizing the unsupervised learning, supervised fine-tuning, and reinforcement learning steps involved in training generative models like LLMs.

The speaker gives an overview of LLMs, explaining their large size and complexity due to the vast amounts of data they are trained on. They highlight the versatility of LLMs in performing various tasks such as text generation, chatbot creation, summarization, translation, and code generation. The speaker also mentions the Transformer architecture as the base model for most LLMs and discusses the different milestones in the development of LLMs, including models like BERT, GPT, XLM, T5, Megatron, and M2M.

The speaker discusses the use of open source LLMs for creating applications, mentioning models like Bloom, Lama 2, Palm, and Falcon Cloud. They provide guidance on how to access and utilize these models, emphasizing that they can be used for various tasks without incurring costs associated with proprietary models like GPT. The speaker also mentions the importance of prompt design and plans to cover this topic in more detail in future sessions.

The speaker provides instructions on how to access and use OpenAI models, including the process of generating an API key and selecting appropriate models for different tasks. They mention the availability of different models on the OpenAI platform and introduce the concept of model hubs. The speaker also talks about the potential use of LLMs in computer vision projects, highlighting the versatility of these models in various applications.

The speaker discusses the concepts of transfer learning and fine-tuning in the context of natural language processing (NLP). They mention a research paper that explores the use of universal language models for text classification tasks. The speaker explains how transfer learning, which was previously used mainly in computer vision, can now be applied in NLP due to advancements in architectures like the Transformer. They emphasize the potential of LLMs in performing a wide range of language-related tasks.

The speaker concludes the session by summarizing the key points discussed and encourages the audience to review the materials and complete the assignments. They mention the availability of recordings on YouTube and the dashboard and provide information about the next session. The speaker also teases the upcoming practical implementation of topics and assures the audience of a comprehensive learning experience.
