Unlock the Power of Generative AI: Webinar Recap with Nabajyoti Boruah
TeamLease Digital Learning hosted an enlightening webinar titled "Unlock the Power of Generative AI," with Nabajyoti Boruah as the keynote trainer, moderated by Dinesh Gupta , Head of Operations - Enterprise Learning, TeamLease Services Limited. This session aimed to provide a comprehensive introduction to the principles and practices of generative artificial intelligence (AI). By the end of the course, participants would have a solid understanding of key generative AI concepts, including machine learning and deep learning models. Dinesh Gupta, the host, kick-started the session with an engaging introduction, emphasizing Nabajyoti Boruah’s extensive expertise. With 19+ years of experience in technology areas like Microsoft Azure, IoT, machine learning, AI, generative AI, Azure Open AI, and serverless computing, Mr. Boruah is a consultant, subject matter expert, certified trainer, and cloud architect, making him exceptionally qualified to lead this session.
Understanding AI: A Deep Dive
The webinar began with a foundational overview of AI, tracing its development from the rule-based systems of the 1950s to the advanced deep learning models we see today. Mr. Boruah explained that the initial AI systems relied heavily on human-created rules to function. These systems evolved into machine learning in the 1960s and 1990s, where machines began learning from data to make predictions and classifications, aiding in decision-making processes within businesses.
Evolution to Deep Learning
The session moved on to deep learning, a subfield of machine learning that involves training neural networks on vast amounts of data. This allows for more complex tasks like image and speech recognition, significantly enhancing the capabilities of AI systems. Mr. Boruah highlighted that deep learning models can perform sophisticated functions, from clustering similar data points to making high-level predictions.
Generative AI: A New Frontier
Mr. Boruah then transitioned to the core topic: generative AI. He defined generative AI as a type of artificial intelligence that creates new content based on input prompts. Unlike traditional AI, which primarily focuses on prediction and classification, generative AI can generate text, images, and even videos. This makes it a powerful tool for various applications, from writing stories and poems to creating detailed reports and coding.
The Backbone: Large Language Models (LLMs)
A significant portion of the webinar was dedicated to explaining large language models (LLMs), the engines driving generative AI. Mr. Boruah described how models like GPT-3 and GPT-4, developed by OpenAI, use deep learning techniques to generate human-like text based on the data they have been trained on. These models are trained on vast datasets, including information from Wikipedia and other comprehensive sources, enabling them to produce coherent and contextually relevant content.
Challenges and Considerations
While the potential of generative AI is immense, there are several challenges associated with Large Language Models (LLMs). One major issue is their static nature; they are limited by the data available at the time of their training. As a result, they might not have the most current information, which can be a significant drawback in fast-evolving fields such as manufacturing, medicine, healthcare, or retail. For instance, if an LLM was trained using data available until 2023, it won't be aware of developments in 2024 unless retrained. Additionally, creating and updating these models is a time-consuming and resource-intensive process.
Solutions to Overcome LLM Challenges
To address these challenges, two primary solutions were discussed: fine-tuning and data grounding, also known as retrieval-augmented generation (RAG).
Fine-tuning: Involves retraining the base model with new data, making the model aware of recent developments. Although fine-tuning can be resource-intensive, it ensures the model remains relevant.
Data grounding (RAG): Leverages a modern database, often a vector database, to store the latest data. The model fetches this data in real-time to generate responses, thus reducing the need for constant retraining and minimizing hallucinations, where the model might generate incorrect or irrelevant information.
Infrastructure and Technical Requirements
Mr. Boruah illustrated these concepts with examples, emphasizing the need for a robust underlying infrastructure, including CPU, memory, and storage, to support the training and fine-tuning processes. He also highlighted that understanding the inner workings of neural networks and the various machine learning terminologies is crucial for anyone looking to delve deeper into creating or modifying LLMs.
Practical Applications of Generative AI
Mr. Boruah illustrated the practical applications of generative AI throughout the session, emphasizing its potential to revolutionize industries. From automating code generation for developers to assisting content creators in writing blogs and articles, generative AI showcases diverse applications. He highlighted the importance of prompt engineering—crafting specific prompts to guide AI in generating desired content. Transitioning from theory to practice, he showcased how technologies like ChatGPT and DALL-E enhance productivity. For example, ChatGPT can translate English phrases into Spanish in real-time, demonstrating its utility in tasks beyond mere theoretical concepts.
Use Cases and Demonstrations
Further, Mr. Boruah discussed using Generative AI for summarizing lengthy articles or research papers. He demonstrated this by summarizing a Wikipedia page on Boeing 747, and then refining the summary into bullet points for clarity. This example underscored the model's ability to retain conversational context and deliver precise information based on user prompts.
He also explored other practical applications, such as generating travel itineraries, writing blog posts, and even conducting research by querying the population of European countries. Each use case highlighted how Generative AI can streamline tasks that typically require significant manual effort, thus showcasing its potential to revolutionize various domains.
Encouraging Practical Experience
Finally, Mr. Boruah invited participants to try out these tools themselves, illustrating the ease of using LLM-based applications for everyday tasks. He encouraged participants to explore the models' capabilities, noting that practical experience is key to understanding the true power and limitations of Generative AI.
Conclusion and Q&A
The session concluded with a Q&A segment, where participants could ask questions through Teams. Mr. Boruah's insights and practical demonstrations provided a comprehensive overview of how Generative AI can be leveraged to solve real-world problems, making the complex concepts accessible and actionable for AI developers and consumers alike.
