GenAI vs Predictive AI

Gen AI creates, Predicitve AI classify ability to create make GenAI very powerful

Large Language Model

LLMs are build by training on large text data . These are useful to generate text, summarize document, answer questions, reason, translate, do SEO of web pages

LLMs are changing the way how documents are analyzed, summarized

LLMs are influential in creating new text and getting used in content generation

Code generation is area that will significantly getreefined by LLMs

With Generative AI progress - one should reconsider how software should be developed.

How to use LLMs and build applications

Consideration while selecting - Open Source vs Closed LLM Closed Model can be access via API and have a cost. Open Model have less cost, more control but may require significant work

LLMs building blocks are Data, Architecture, Training, Inference

While making decisions about Closed vs Open model you should consider above factors, control needed, IP risks etc

Lllama and Hugging Face are 2 famous open source model. ChatGPT, Bard, Palm , Claude are closed models.

LLM Comparision Criteria

Consideration while comparing - LLM for accuracy and size More complexity and size can be good or bad

Model parameter indicate complexity. Bigger paramter size indicate ability to handle complexity

Top most criteria should be - accuracy for given task

In many cases ability to fine tune a model, reasoning capabilities are impotant too.

Guardrails for GenAI LLM and Chatbots

Safety for LLM and GenAI

Guardrails are essentially guidelines and controls that steer the LLM's outputs in the desired direction.

Here are some ways to keep your LLM on track:

Input Validation: Set criteria for what kind of information the LLM can process, preventing nonsensical or malicious inputs.
Output Filtering: Review and potentially edit the LLM's outputs before they are used, catching any biases or factual errors.
Real-time Monitoring: Continuously track how the LLM is being used and intervene if it generates harmful content.
Human oversight: Ensure humans are always involved in the LLM interaction

Foundation Model

Act as platform. They can be use as out of box and advanced model can be trained on these.

Foundation model work out of box for universal scenarios.

Specific models can be trained on these.

Reduce the labeling requirements

As FMs are exposed to internet scale data and various forms and myriad of patterns, FMs learn to apply their knowledge within a wide range of contexts.

Consideration to Extend Foundation Model

Consider extending Foundation model for compettive advantage

Extend and Fine tune for specific task

Train custom model for specific domain

Build datasets on which you can train model

Prompt Engineering

Design input in natural language to get results you want from LLM

Give instruction , Give persona, add delimeter

Add examples, provide steps to complete task

Specify output format such as HTML, JSON, Table to produce

Retrieval-Augmented Generation (RAG)

Add memory to LLM and GenAI

Retrieval-Augmented Generation. It's a technique that helps large language models. Before answering your question, the LLM uses RAG to search a vast external knowledge base for relevant information.

With this extra knowledge, the LLM can provide more accurate and informative answers. RAG combines the vast knowledge of LLMs with your data, enhancing AI's ability to provide contextually rich responses.

RAG is extremly ueful when you need to answer question on specific domain, latest and up to date information or use internal knowledge. Use RAG is
Domain-specific knowledge: If your assistant needs to be an expert in a specific domain, RAG can be used to integrate relevant databases or knowledge repositories to enhance its understanding.
Accuracy is crucial: If your LLM assistant needs to provide highly accurate information, especially on factual topics like science, history, or specific procedures, RAG can ensure responses are grounded in real-world knowledge.
Combating hallucinations: LLMs can sometimes make up information, called hallucination. RAG combats this by providing verifiable evidence to support the response.
Building trust: By allowing users to see where the information comes from (think footnotes!), RAG fosters trust and transparency in the assistant's responses.

AI Assistant Tradeoff Factors

You want better accuracy, performance and cost. However priortize what is most important

Trade Off Factors For AI Assistants

3 Dimensions

Accuracy : Lead toUser Trust and Effectiveness: Higher accuracy in understanding and responding to user queries builds trust and reliability. Accurate AI assistants can effectively handle complex tasks, providing precise information and solutions.
Performance : Better Speed and Scale lear to quick response. High-performance AI assistants provide quick responses, improving user experience and efficiency. Efficient performance ensures that the AI can handle numerous requests simultaneously, essential for scaling operations.
Cost : Lead to adoption and ROI generation. Lower costs can make AI assistants accessible to a broader range of users and businesses. Affordable solutions encourage wider adoption, enabling more industries to benefit from AI.

Unleash the power of Similarity Search

Vector DB and Vector Embeddings

Vector DB store date in vector embeddings which are high dimension vectors that represent features or attributes of data. Traditional DB store dat in rows and columns. In traditional db each columen has signle field and each row is a record.

Traditional DBs are good for extact match vs vector dbs are great for similarity search.

Vector Dbs have great use in many use cases like:

Text Search, Question Answer Bot
Vision search
Find similar design
Efficient analysis of audio
Find visually similar images e.g. blue water

OpenAI Fine tuning

Fine tune Open AI by your training data to handle edge cases, complex scenarios

Finetuning and building custom model give you edge

With Fine tuning you have your own model, your IP based on data

With Fine tune model, you can handle complex scenarios

Before Fine tuning - try prompt engineering, few shot learnings.

Fine tuning Steps

Fine tuning Steps- Prepare Data in same format as Completion API Create 10-100 examples of each type

One Fine tune - evaluate the results

Make a inference calls/li>

Do Error Analysis.

Tech Stack and modeling architectures

There are many architectures - Transformer Auto encoder, GAN, Diffusion model and RL

Generative AI is based on "comprehend existing" data and determine trajectories data can take. It uses it for geenration

Diffusion architecture is suitable for generation

Transformer are suitable for language gentration in sequence

How to Evaluate Gen AI

Identify what is important - Creativity, Realisim , Diversity and then evaluate

Traditional machine learning model has evaluaition metrics like accuracy. Generative AI creates new data. It evaluation is based on subjecive measures like diversity of data, realism, nobalty, creativity. It is hard to evaluate or benchmark geenrative models.

Generative AI adoption framework

Consider High Risk vs Low Risk application. Also consider generic data vs custom data dimension

Use above dimensions to identify quardant of your use case(s). Low risk and applicability of generic data e.g content writing for sales,travel guide are easy to adopt.

Areas where universal data is available but risk of geenrating wrong results are high - it is opportunity for companies that want to train and sell custom models

Areas where task specifci fine tuning is needed, is opprtunity for services companies

Companies that want to build defendable IP will focus on create new dataset and model training on these dataset for areas where risk is high and universal dataset are not available.

Trade off and Conflicts

Challenges, Ethical Issues, Copyright issues, Data ownership question, Environmental issues

Generative AI has potential, but there are many challenges and open questions. One should consider these before using geenrative AI in enterprise(s)

Uncontrolled data production

LLM, Image generation can produce variety but There is very less control how new data will be generated

Generative AI is based on "comprehend existing" data and determine trajectories data can take. It uses it for creating new data. However the method of producing new variation of data makes it controllable.

Generative Model output is unpredicatble and uncontrollable. Main issue is - how to get confidence if you want to use it in mission critical envioronment.

Large language Model (LLM) inherit bias from data they are trained on.

There are open questions on who have copy right on generated content. In future there may be new laws that will impact consumers of generative AI

LLM or Image model that are trained on universal data and produce new data are compute intensive. There are impact of enviornment one need to consider.

Enviornment concern and legal question

One need to responsibly use Generative AI

There is significant amount of compute, energy usage. There is significant amount of carbon emission. One need to ensure it is for good cause and not for producing variation(s)

Dataknobs has created set of controls to handle this
