The Next Evolution of AI: Introducing Self-Reflecting Multi-Agent RAG Systems

Artificial intelligence systems have seen remarkable advances in recent years through innovations like large language models and multi-modal architectures. However, critical weaknesses around reasoning, factual grounding, and self-improvement remain barriers to robust performance. An emerging approach combining collaborative multi-agent interaction, retrieval of external knowledge, and recursive self-reflection holds great promise for overcoming these limitations and ushering in a new evolution of AI capabilities.

Multi-agent architectures draw inspiration from the collaborative intelligence exhibited by human groups and natural systems. By dividing cognitive labor across specialized agents, strengths are amplified and limitations mitigated through symbiotic coordination. Retrieval augmented systems fuse this collective competence with fast access to external databases, texts, and real-time data - providing vital context missing within isolated models today.

Building recursive self-reflection into both individual agents and the system as a whole closes the loop, enabling continuous optimization of reasoning processes in response to insights gained through experience. This capacity for introspection and deliberative thinking allows the system to operate in a more System 2 thinking oriented manner.

For example, by assigning distinct agents specialized roles in critiquing assertions made by peer agents, the system essentially institutes deliberate verification procedures before accepting conclusions. Facts retrieved from external sources can validate or invalidate the logic applied, promoting evidence-based rational thinking. And recursive self-questioning provides a mechanism for critical analysis of internal beliefs and assumptions that overrides blindspots.

Together, these three mechanisms offer the foundations for AI systems capable of open-ended self-improvement through rigorous reasoning and abstraction. Peer critiquing across diverse agents identifies gaps or contradictions in thinking. Real-world data grounds beliefs in empirical facts. And recursive self-questioning pressure tests the integrity of all assertions made. Through such recurring examination, vulnerabilities are uncovered and addressed, incrementally strengthening the system's intelligence.

While substantial research is still needed to effectively integrate these capabilities, the promise is profound. Such an architecture could greatly augment AI aptitude for deep domain expertise, creative speculation, and nuanced judgment - hallmarks of advanced general intelligence. The result is systems exhibiting the flexible cognition, contextual reasoning, and capacity for lifelong learning characteristic of human minds but at machine scale.

FLOW Pattern: Comprehensive Knowledge Extraction with Large Language Models

Intent:

The FLOW pattern aims to enable the systematic extraction, organization, and synthesis of comprehensive knowledge from large documents or transcripts using large language models, such as GPT-3. It addresses the limitation of these models' context window, allowing them to handle large documents by chunking them up in the different stages of the pattern.

Motivation:

Large language models often have a limited context window, which restricts their ability to ingest and analyze complete large documents at once. The FLOW pattern seeks to overcome this limitation by breaking down the document into manageable chunks, enabling a more comprehensive analysis and synthesis of information.

Implementation:

  1. Find: Extract specific topics or perspectives from the document or transcript in manageable chunks, considering the limitation of the model's context window.
  2. Link: Synthesize the extracted content from various chunks of the document or transcript, ensuring coherence and connectivity between different elements, while noting that the information comes from different parts of the source material.
  3. Organize: Structure the linked content in a logical and coherent manner, facilitating a systematic analysis of the document's core concepts and themes using the model's iterative capabilities.
  4. Write: Expand and elaborate on the organized content, producing a well-developed document that is informative, engaging, and accessible to the target audience, leveraging the model's text generation capabilities.

Consequences:

By implementing the FLOW pattern with large language models, organizations can effectively overcome the limitations of the context window, enabling a more comprehensive analysis of large documents and transcripts. This, in turn, enhances the model's ability to provide meaningful insights and make informed decisions based on a more holistic understanding of the underlying information.

Example Use Case:

An organization utilizes the FLOW pattern with a large language model like GPT-3 to create comprehensive meeting minutes from a transcript, effectively overcoming the context window limitation by chunking the document into manageable sections for analysis and synthesis.

Summary:

The FLOW pattern, when implemented with large language models, serves as an effective approach for comprehensive knowledge extraction from large documents or transcripts. By addressing the context window limitation, it enables organizations to derive meaningful insights and make informed decisions based on a more comprehensive understanding of the underlying information.

Transforming Document Exploration: Using GPT-3 to Create a Chatbot that Answers Your Questions

GPT-3 is the underlying model of ChatGPT. It is an advanced language model that can generate text but it can't find information that is not already in the model. In additon, there are limitation to feed long text to GPT-3. In this article, we will show you how to use a technique called conditional generation to build a chatbot that can help you explore long documents.

Conditional generation is a way of training a language model to understand the context of a document and generate answers to questions about it. We will take the following steps to build the chatbot:

  1. Create a corpus from the document.
  2. Match the user's question to the relavant passages in the corpus.
  3. Create a prompt that includes the context of the question.
  4. Send the prompt to GPT-3 to generate an answer.
  5. Create a function that combines steps 2-4.
  6. Test the chatbot by creating a question-answer loop.
  7. Use Gradio to create an interface for the chatbot.
In this exercise, we will build a chatbot to answer the question in an employee handbook.

Create a corpus from the document

First we have prepared a file HKIHRMEmployeeHandbook.txt which is text version of a sample employee handbook created by Hong Kong Institute of Human Resource Management.

To start, we are using a python library called "sentence-transformers" to create a corpus of embeddings from the text document "HKIHRMEmployeeHandbook.txt". The sentence-transformers library is an NLP library that makes use of pre-trained transformer-based models, like BERT, RoBERTa, DistilBERT, and, in this case, multi-qa-mpnet-base-cos-v1, to generate embeddings for each sentence in the corpus. This is useful for our chatbot application as it allows us to find the most relevant passage in our document for the user's query. This will help to provide more accurate and useful answers for the user.

Embeddings are a way to represent text in a numerical form that can be used for comparison and similarity calculation by the model. In this case, we are using sentence-transformers library to convert the text into embeddings. These embeddings are a compact and dense representation of the text, which can be used to compare and measure similarity between different texts.

There are several advantages of using embeddings instead of keyword search when building a chatbot for document exploration:
  • Semantic Similarity: Embeddings capture the semantic similarity between sentences, which allows for more accurate and relevant matches between the user's query and the passages in the corpus.
  • Handling synonyms and variations: Embeddings can handle synonyms and variations in the query, which are difficult to handle with traditional keyword search. For example, if the user asks "what are the benefits of working overtime?" and the document talks about "compensation for working beyond regular hours", the embeddings will be able to match the query with the relevant passage, even though the words in the query and document are different.
  • Handling context: Embeddings can also capture the context in which a word is used, which allows for more accurate matches between the query and the passages in the corpus. For example, "what are the benefits of working overtime?" and "what are the drawbacks of working overtime?" have similar keywords but opposite meaning, embeddings can help to understand the context and give the correct answer.
  • Scalability: Embeddings can handle large datasets and can be used to match queries against a large corpus of documents efficiently.
Overall, using embeddings instead of keyword search improves the accuracy and relevance of the chatbot's answers, and provides better user experience.

Match the user's question to the relavant passages in the corpus

Once we have the embeddings, we can find the most similar passages in the document to the given query. The util.semantic_search method to find the most similar passages in the corpus based on the query embedding and the corpus embeddings. The top_k variable controls how many passages to retrieve. After getting the passages from the corpus, they are joined as a whole piece together with linebreak to form the context. The result is as follows:

2.2 Working Hours 3.2 Overtime Compensation Prior approval must be obtained from respective supervisor for working overtime. Overtime for employees at grade 7-10 will be compensated by pay at the following rates: Category 1 a) For non-shift employees, Monday to Friday starting from an hour after normal working hour to 12:00 midnight and Saturday after 2:00 p.m. b) For shift employees, overtime worked beyond his shift 1.5 times hourly rate Overtime for employees at grade 4-6 will be compensated by way of time off. Such compensation leave will only be granted when their department’ s workload permits. Any overtime not compensated in the form of leave by the end of the calendar year will be paid in the following February at the rate of 1.5 times the employee's hourly rate. 3.3 Annual Bonus Employees who work overtime in the following conditions are entitled to claim for meal allowance: - overtime for 3 consecutive hours from Monday to Saturday; - overtime for 6 consecutive hours on Sunday or public holidays Employees who are required to report for duty outside office hours in case of emergency will be entitled to an emergency allowance and compensation leave 4.5 Compensation Leave or Time-off for Overtime Work Employees at grade 4-6 who have worked overtime will be compensated by way of time off. Such compensation leave will only be granted when their department’ s workload permits. Please also refer to “Overtime Compensation” under Section 3.2 of this handbook for details.

You can observed that all passages retrieved are more or less relavant to the overtime question.
 

Create a prompt that includes the context of the question

Then, we can creating a prompt template. The prompt will be created and send for GPT-3 to generate an answer for the query based on the context. The following prompt will be created

Context: 2.2 Working Hours 3.2 Overtime Compensation Prior approval must be obtained from respective supervisor for working overtime. Overtime for employees at grade 7-10 will be compensated by pay at the following rates: Category 1 a) For non-shift employees, Monday to Friday starting from an hour after normal working hour to 12:00 midnight and Saturday after 2:00 p.m. b) For shift employees, overtime worked beyond his shift 1.5 times hourly rate Overtime for employees at grade 4-6 will be compensated by way of time off. Such compensation leave will only be granted when their department’ s workload permits. Any overtime not compensated in the form of leave by the end of the calendar year will be paid in the following February at the rate of 1.5 times the employee's hourly rate. 3.3 Annual Bonus Employees who work overtime in the following conditions are entitled to claim for meal allowance: - overtime for 3 consecutive hours from Monday to Saturday; - overtime for 6 consecutive hours on Sunday or public holidays Employees who are required to report for duty outside office hours in case of emergency will be entitled to an emergency allowance and compensation leave 4.5 Compensation Leave or Time-off for Overtime Work Employees at grade 4-6 who have worked overtime will be compensated by way of time off. Such compensation leave will only be granted when their department’ s workload permits. Please also refer to “Overtime Compensation” under Section 3.2 of this handbook for details. Answer the following question: Q: what should I do if I worked overtime? A:

You can try a few other forms like:
  • Answer the following question. If the answer cannot be found in the context, write "I don't know"
  • Answer the following question. If the answer cannot be found in the context, rewrite the question that is more related to the context by starting with "Do you want to ask" and then elaborate the answer

Send the prompt to GPT-3 to generate an answer

The following code is using the OpenAI API to generate a response for the prompt using GPT-3. GPT-3 will come up with an answer that fits the context:

If you are an employee at grade 7-10, you should obtain prior approval from your supervisor and you will be compensated by pay at the rate of 1.5 times your hourly rate. If you are an employee at grade 4-6, you will be compensated by way of time off. Such compensation leave will only be granted when your department’s workload permits. Any overtime not compensated in the form of leave by the end of the calendar year will be paid in the following February at the rate of 1.5 times your hourly rate.

Create a function that wraps up everything

Wrapping the code into a function called answer(query) allows for easy reuse of the code and inputting of different queries. This function takes in a query string, and return the response of the API. This makes it easy to input different queries and get an answer without having to repeat the previous steps every time.

Test the chatbot by creating a question-answer loop

Here, we have an infinite loop that repeatedly prompts the user for a query, and exits the loop when the user enters "xxx". You can input multiple queries and get answers without having to restart the code. It allows easy testing of the function by allowing the user to input different queries and see the answers generated by GPT-3. The output will be as follows:

Q: do I get paid if I got sick? A: Yes, employees who are not able to report for duty due to illness are entitled to full pay sick leave, subject to a maximum of the lesser of 120 days or the number of sickness days that the employee has accumulated according to provisions in the Employment Ordinance. Additionally, employees who suffer from injury arising out of and in the course of employment are entitled to compensation in accordance with the Employee Compensation Ordinance. ====================================================================== Q: what should I do if I got sick? A: If I become ill, I should notify my immediate supervisor as soon as possible and provide a medical certificate if necessary. I am entitled to full pay sick leave, subject to a maximum of 120 days or the number of sickness days I have accumulated according to the Employment Ordinance. If I have to leave during office hours due to sickness or personal reasons, I must obtain prior approval from either my supervisor, department manager or the Human Resources Department. ====================================================================== Q: xxx

Use Gradio to create an interface for the chatbot

Finally, let's use gradio library to create a (GUI) for the answer(query) function defined earlier: Now you have a more user friendly GUI to ask the questions:
Try it out in Colab: Open In Colab

AppDynamics Agent Instrumentation for Java 6 Applications

AppDynamics Agent can monitor Java 6 applications. However, modern applications does not supporting TLS version older than TLS 1.2. So, the SaaS controller does not support using TLS 1.1, TLS 1.0, and SSH 3. On the other hand, being an 2006 technology, Java 6 does not support TLS 1.2 out-of-the-box.

Upgrading the JVM seems to be an obvious solution. However, it might not be possible as it would involve a lot of effort to re-test. Some library might not even compatible with newer JVM.

Fortunately, we can make use of Java's pluggable cryptography extension (JCE) and Java Secure Socket Extension (JSSE). Bouncy Castle is one of the library to provider of the security feature [ref: stackoverflow.com].

The following Dockerfile demonstrate the following:

  1. Use yannart/jboss-5.1.0.ga-jdk6 as the base image
  2. Copy the content of AppServerAgent to /opt/appdynamics
    • Java agent is separately downloaded
    • controller-info.xml shall be configured 
  3. Download and install jurisdiction policy files for "unlimited strength" cryptography
  4. Download and install Bouncy Castle 1.66
  5. Copy the java.security file
  6. Configure Java agent instrumentation via environment variable

The changes of the java.security is as follows:

  1. Set the priority of Bouncy Castle as the first provider of JCE and JSSE
  2. Set the default SocketFactory

For what it's worth, here is the full java.security file:
