Presentation
What are LLM Models - Not Skynet
Large Language Model (LLM) refers to a class of Generative AI models that are designed to understand prompts and questions and generate human-like text based on large amounts of training data. LLMs are built upon Foundation Models which have a focus on language understanding.
Common Tasks
Text and Code Generation: LLMs can generate code and data analysis text based on specific prompts
Natural Language Processing (NLP): Understand and generate human language, sentiment analysis, translation
Text Summarization: LLMs can condense lengthy pieces of text into concise summaries
Question Answering: LLMs can access and process information from various sources to answer questions, making a great fit for chatbots
Training LLM Models - Secret Sauce
Models are trained using a combination of machine learning and deep learning. Massive datasets of text are collected, cleaned, and fed into complex neural networks with multiple layers. These networks iteratively learn by analyzing patterns in the data, allowing them to map inputs like chart data to desired outputs, such as chart analysis.
Training Process:
Data Collection: Sources from books, articles, code repositories, and online conversations
Preprocessing: Data cleaning and formatting for the ML algorithms to understand it effectively
Model Training: The neural network architecture is trained on the data. The network adjusts its internal parameters to learn how to map input data (user stories) to desired outputs (code snippets)
Fine-tuning: Fine-tune models for specific tasks like code generation, by training the model on relevant data (e.g., specific programming languages, coding conventions).
Transformer Architecture - Not Autobots
Transformer is a neural network architecture that excels at processing long sequences of text by analyzing relationships between words, no matter how far apart they are. This allows LLMs to understand complex language patterns and generate human-like text.
Components
Encoder: Process the input (use story) by using multiple encoder layers with self-attention Mechanism to analyze the relationship between words
Decoder: Uses the encoded information and its own attention mechanism to generate the output text (like code), ensuring it aligns with the text.
Attention Mechanism: Enables the model to effectively focus on the most important information for the task at hand, leading to improved NLP and generation capabilities.
Fine-Tuning for Specific Domain
Fine-tuning LLMs is a process to specialize a pre-trained model into a specific domain like data analysis with your process information.
Process:
- Use the knowledge and parameters gained from a large pretrained dataset, source model
- Enhance the model performance by retraining the source model with a domain specific and smaller dataset
- Use the target model for the final integration
Tokens - The Building Blocks of Language Models
Large language models work by dissecting text into a sequence of tokens. These tokens act as the building blocks, allowing it to grasp the essence, structure, and connections within the text.
Details
- Tokens can be individual words, punctuation marks, or even smaller sub-word units, depending on the specific LLM architecture.
- The length of a word can influence the number of tokens it generates.
- Similar to how Lego bricks come in various shapes and sizes, tokens can vary depending on the model's design.
- Measure cost.
👉 Think of tokens as Lego blocks
Prompt Engineering - What is it?
Prompt engineering is the process of designing and optimizing prompts to better utilize LLMs. Well described prompts can help the AI models better understand the context and generate more accurate responses.
Features
Clarity and Specificity: Effective prompts are clear, concise, and specific about the task or desired response
Task Framing: Provide background information, specifying the desired output format (e.g., code, email, poem), or outlining specific requirements
Examples and Counter-Examples: Including relevant examples and counterexamples within the prompt can further guide the LLM
Instructional Language: Use clear and concise instructions to improve the LLM's understanding of what information to generate
Chart Analysis with AI
By combining existing charts with AI-driven analysis, we can unlock deeper insights, automate interpretation, and empower users to make more informed decisions.
Data Analysis Flow:
Chart Data: Identify the key data points from the chart (e.g., x-axis values, y-axis values, data labels, limits).
Chart Prompt: Format this information in a concise and human-readable format, such as:
"We are looking at a control chart measuring Curvature data points…"
- Analysis Prompt: Provide details about what would you like to learn from the data:
"Interpret this chart, data series, limits and action items to take?"
👉 LLM generated analysis is not perfect, if the prompt is not detail enough, hallucinations may occurred
Smart Charts Powered by AI - Summary
LLMs empower developers, data engineers/analysts, and scientists by enhancing data understanding through AI-driven chart analysis. To ensure accurate and insightful analysis, crafting detailed prompts is crucial.
Provide Chart Context:
- Chart Type: (e.g., line chart, bar chart, pie chart, scatter plot)
- Chart Title
- Data Series
- Data Ranges/Limits: (e.g., Time period, Upper/Lower Limits)
Provide Guiding Questions:
- What is the overall trend of the data?
- Are there any significant peaks or dips?
- Are there any outliers or anomalies?
- What are the key takeaways from this chart?
- What actions, if any, should be considered?
👉 By framing the prompt with contextual and guiding questions, you effectively "train" the model to analyze the chart in a more human-like and insightful manner.
