2. Generative AI Generative AI is a type of artificial intelligence that can create new, original content such as music, images, and text. It uses machine learning algorithms to generate novel outputs by learning patterns and structures from existing data.
3. What is LLM? Understanding Language Models LLMs Can Understand Context LLMs can comprehend the context and meaning behind text, enabling them to generate coherent and relevant responses. Generative Capabilities LLMs can generate human-like text for various applications, such as content creation, translation, and conversational AI. Large language models are machine learning models trained to predict the next word of a sentence. It would appear that the application talks to you like a human because the output is grammatically correct, related to the input, reasoning,etc.
4. Evolution of Large Language Models early 2000s early neural networks ~2003 RRNs 2013 Word2Vec 2014 Attentions Mechanism 2017 Transformers 2018 BERG,GPT 2019 GPT-2 2020 GPT-3 2022 GPT-3.5 2023 GPT-4 NOW GPT-4o

6. ChatGPT came on the 30th of November, 2022 It functions similarly to a search engine but with human-like responses. OpenAI, the organization behind ChatGPT, used 175 billion parameters to train ChatGPT version 3. ChatGPT holds the world record. ChatGPT holds the world record for the fastest application to reach a million users — in just five days. Meanwhile, it took Instagram 2 1/2 months and Spotify 5 months. GPT-4 came on the 14th of March, 2023 with higher accuracy than GPT-4 using approximately 100 trillion parameters. A week later, OpenAI released ChatGPT plugins which let the AI interpret programming language code and do an internet search before responding to the users. It also has a marketplace allowing businesses to integrate their custom apps.
7. Value Proposition to Companies and Businesses Intelligent chatbots for customer support Deploy chatbots trained on conversational data to provide 24/7 customer assistance, reducing costs and improving response times. Content generation and personalization Leverage language models to generate personalized content such as product descriptions, marketing materials, and targeted recommendations.

8. AI Services and Platforms There are several services and platforms out there. We can use OpenAI, Azure OpenAI service, Google Vertex AI, Hugging Face, AWS Bedrock, and more.
9. Limitations of Large Language Models Training Data Limitations LLMs are limited to the information available in their training data, which is a static snapshot of data until a certain cut-off date (e.g., April 2023 for GPT-4). While LLMs are powerful language models, they have inherent limitations due to their training data, predictive nature, and lack of true understanding and reasoning capabilities.
10. Limitations of Large Language Models Hallucinations and Factual Errors LLMs can generate plausible-sounding but factually incorrect responses, known as hallucinations, due to their predictive nature and lack of true understanding. While LLMs are powerful language models, they have inherent limitations due to their training data, predictive nature, and lack of true understanding and reasoning capabilities.
11. Limitations of Large Language Models Lack of Common Sense Reasoning LLMs struggle with common sense reasoning and understanding the context and implications of their responses. While LLMs are powerful language models, they have inherent limitations due to their training data, predictive nature, and lack of true understanding and reasoning capabilities.
12. Prompts play a crucial role in communicating and directing the behavior of Large Language Models (LLMs) AI. They serve as inputs or queries that users can provide to elicit specific responses from a model.

16. Components Kernel the kernel where we’ll register all connectors and plugins, in addition to configuring what’s necessary to run our program Memories allows us to provide context to user questions. This means that our Plugin can recall past conversations with the user to give context to the question they are asking. Planner is a function that takes a user’s prompt and returns an execution plan to carry out the request. Supports Task Automation, Customizable workflows, Dynamic problem-solving capabilities. Planner Generation : 'Sequential Planner, Basic Planner, Action Planner, Stepwise Planner. Connectors act as a bridge between different components, enabling the exchange of information between them. Integration with AI models: HuggingFace, Oobabooga, OpenAI, AzureOpenAI Support for existing RDBMS & NoSQL : Postgres, Redis, SQLite, Choma, Milvus Plugins can be described as a set of functions, whether native or semantic, exposed to AI services and applications. There are two type of functions. - Semantic functions (skprompt.txt) : These functions listen to user requests and provide responses using natural language. - Native Functions : These functions are written in C#. They handle operations where AI models are not sutables, such as : Math calculations, Accesing REST APIs
17. AI Component's Functionalities Plugin A task-based component designed for specific functionalities like image manipulation, text translation, or data analysis. Planner A workflow management component responsible for decision-making, action optimization, and task coordination. Persona An identity or personification assigned to an AI system, such as a customer service chatbot with a predefined personality. Agent An autonomous entity that perceives its environment and takes goal-oriented actions to achieve specific objectives. Co-pilot A collaborative AI component that assists developers or users by completing tasks under their direction, like GitHub Copilot for code completion. Btw all co-oilots are planner :)
18. Copilot Works side-by-side with a user to complete tasks. These agents provide more interactive and supportive roles, assisting users in accomplishing specific tasks by leveraging more advanced AI capabilities. RAG Enhances conversations by grounding responses in real data through retrieval techniques, improves the relevance and accuracy of its responses. Chatbot Engages in simple back-and-forth conversations with a user. These are the most basic form of AI agents, typically limited to predefined scripts and basic interaction. Fully autonomous Capable of responding to stimuli with minimal human intervention. These agents operate independently, making decisions and taking actions without needing continuous guidance from humans Types Of Agents There's a wide spectrum of agents that can be built, ranging from simple chat bots to fully automated AI assistants

26. The Rise of Vector Databases in AI A vector database indexes and stores vector embeddings for fast retrieval and similarity search. Vectors in programming are straightforward: an array of numbers representing both size and direction. Easily defined by coding a numerical array. The Vector database is a new kind of database for the AI era
27. Unstructured data > %80 Why do we need vector database A Vector database indexes and stores vector embeddings for fast retrieval and similarity search.
28. How do you generate or create embeddings? The process of generating embeddings is that you need an embedding model from a paid source like OpenAI’s "text- embedding-ada-002" model or an open source from HuggingFace’s "SentenceTransformers"
29. Vector embeddings ( 2D example) JavaScript C# GoLang [ 2.5 , -2 ] [ 2.5 , -3 ] [ 4 , -1 ] Fenerbahçe Champion Türkiye [ 3.4 , 5 ] [ 2.5 , 6 ] [ 4 , 1 ] Laptop Desktop Widget [ -3.4 , 5 ] [ -2.5 , 6 ] [ -4 , 1 ]
30. Clusters of embeddings based on their similarity The embeddings are grouped depending on how closely the words are related. Your query, for example, a desktop, might bring a Macbook and laptop because they are all personal computers or gadgets
31. Clusters of embeddings based on their similarity The thyme, rosemary, and oregano are located in the herbs area. And just like in GPS, the embeddings are like latitude and longitude coordinates.
32. The solutions to the problems of LLMs Retrieval-Augmented Generation From the user, convert your prompt into embeddings for similarity search in the vector db. Then, arrange the original prompt plus the vector DB’s results into the prompt template before sending it to the LLM provider. RAG is a design pattern for augmenting a model’s capabilities by combining it with a retrieval component.
33. The solutions to the problems of LLMs Hybrid RAG Which uses a keyword search as a supplement for improving results. We combine the vector and keyword search results before sending them to the LLMs. RAG is a design pattern for augmenting a model’s capabilities by combining it with a retrieval component.
34. The solutions to the problems of LLMs Hybrid RAG + Re-ranking The goal of re-ranking is to improve the relevance of the results returned by an initial retrieval query. RAG is a design pattern for augmenting a model’s capabilities by combining it with a retrieval component.
