Agents flip our copilot paradigm: from AI being human's copilot to humans being AI's copilot.

The paradigm of AI copilots is undergoing a transformation, shifting from AI serving as a supportive assistant to humans, to humans taking on the role of AI copilots. This shift represents a significant change in how individuals interact with AI, enabling users to harness the power of AI to enhance decision-making and efficiency. This shift in the copilot paradigm signifies a move towards a more collaborative and empowering relationship between humans and AI, where humans actively engage with AI to augment their capabilities and productivity.


There are 3 stages; Beside, Inside, & Outside - Steven Bathiche

  1. AI will be beside what we are doing: AI is a valuable tool; a helper, a sidebar, an assistant that can aid us in many aspects of our lives. As a conversational AI, it can help us with research, writing, and presentations, breaking our mental blacks, managing our personal lives by scheduling appointments and managing our finances. By automating tasks such as data entry and email processing, AI frees up our time so that we can focus on more important tasks.
  2. AI will inside what we are doing: AI will become even more integrated into our daily lives, understanding our needs and preferences and anticipating our actions. It will be everywhere, acting as the scaffolding for our interactions with technology. Instead of waiting for us to make a keystroke or select an application, AI will take the lead, choosing the best app for us and coaching us through a vast array of possibilities.
  3. AI will be outside what we are doing: AI agents will act as intermediaries, pulling information from disparate data sources and interpreting the world for us. They will help us navigate and understand the context, acting as facilitators and eliminating the challenge of starting with a blank sheet.

An intelligent agent is anything which perceives its environment, takes actions autonomously in order to achieve goals, and may improve its performance with learning or acquiring knowledge. An agent has an "objective function" that encapsulates all the IA's goals. Such an agent is designed to create and execute whatever plan will, upon completion, maximize the expected value of the objective function.[2] For example, a reinforcement learning agent has a "reward function" that allows the programmers to shape the IA's desired behavior,[3] and an evolutionary algorithm's behavior is shaped by a "fitness function". - Wikipedia

Jarvis

YouTube ... Quora ...Google search ...Google News ...Bing News

Jarvis is a project from Microsoft that uses ChatGPT as the controller for a system where it can employ a variety of other models as needed to respond to your prompt. Microsoft Jarvis connects LLMs with ML community. Language serves as an interface for Large Language Model (LLM)s to connect numerous AI models for solving complicated AI tasks. Solving complicated AI tasks with different domains and modalities is a key step toward advanced artificial intelligence. While there are abundant AI models available for different domains and modalities, they cannot handle complicated AI tasks. Considering Large Language Model (LLM) have exhibited exceptional ability in language understanding, generation, interaction, and reasoning, we advocate that LLMs could act as a controller to manage existing AI models to solve complicated AI tasks and language could be a generic interface to empower this.


HuggingGPT is one instance of Jarvis, a web-based chatbot at Hugging Face, an online AI community which hosts thousands of open-source models.


When a user makes a request to the bot, Jarvis plans the task, chooses which models it needs, has those models perform the task and then generates and issues a response. The workflow of this system consists of four stages:

  1. Task Planning: Using ChatGPT to analyze the requests of users to understand their intention, and disassemble them into possible solvable tasks via prompts.
  2. Model Selection: To solve the planned tasks, ChatGPT selects expert models that are hosted on Hugging Face based on model descriptions.
  3. Task Execution: Invoke and execute each selected model, and return the results to ChatGPT.
  4. Response Generation: Finally, using ChatGPT to integrate the prediction of all models, and generate answers for users.

Auto-GPT

YouTube ... Quora ...Google search ...Google News ...Bing News



Auto-GPT (AutoGPT) is an open-source Python AI Agent application based on GPT-4 that can self-prompt. This means that if the user states an end goal, the system can work out the steps needed to get there and carry them out. Auto-GPT works by setting a goal; the AI will then generate and complete tasks. Basically, it does all the follow-up work for you, asking and answering its own prompts in a loop. It utilizes the GPT-4 API and can perform a task with little human intervention.

Auto-GPT manages short-term and long-term memory by writing to and reading from databases and files; manages context window length requirements with summarization; can perform internet-based actions such as web searching, web form, and API interactions unattended; and includes text-to-speech for voice output. However, it has limitations in understanding and retaining extensive contextual information because the GPT model it leverages has a token limit. One way to address this contextual issue is to access a window of historical messages, such as the last ten messages or a fixed number of tokens, without exceeding the token limit of a single conversation. However, this method restricts Auto-GPT from accessing earlier contextual information, which might lead to the failure of Auto-GPT to accomplish its goal

To install Auto-GPT, you will need to have Python and Pip installed on your computer. You can download the latest version of Python from the official website and install it on your computer. You will also need to add API keys to use Auto-GPT. You can go to the GitHub release page of Auto-GPT and download the ZIP file by clicking on “Source code (zip)”

If you want Auto-GPT to speak using ElevenLabs, you will need to have an ElevenLabs API key. You can obtain your ElevenLabs API key from their website. Once you have your API key, you can add it to the .env file in the Auto-GPT directory.

[bots] all communicating with other bots, but we find that you know it doesn't really make sense for these bots to like reduce everything to language and then send the language over and then have it be you know kind of re-embedded. Like why don't they just talk to each other in their native language which is this high dimensional space. ... you can adapt embeddings to another, you know, embedding space with basically just like a single of your projection. - Nathan Labenz | The Cognitive Revolution; 'Looking Up the AI Exponential with Azeem Azhar of the Exponential View episode'

Agents with Reinforcement Learning (RL)

Reinforcement Learning (RL) aims to make an agent (our “model”) learn through the interaction with an environment (this can be either virtual or real). RL was firstly developed to adhere to Markov Decision Process (MDP)es. In this ambit, an agent is placed in a stochastic stationary environment and tries to learn a policy through a reward/punishment mechanism. In this scenario, it is proved the agent will converge to a satisfactory policy. However, if multiple agents are placed in the same environment, this condition is no longer true. In fact, before the learning of the agent was only dependent on the interaction between the agent and the environment, now it is also dependent on the interaction between agents


Multi-Agents Reinforcement Learning (MARL)

In a similar vein, multi-agent RL also addresses sequential decision-making problems, but with more than one agent involved. In particular, both the evolution of the system state and the reward received by each agent are influenced by the joint actions of all agents. More intriguingly, each agent has its own long-term reward to optimize, which now becomes a function of the policies of all other agents.

  • Markov/Stochastic Games
    • Cooperative Setting
    • Competitive Setting
    • Mixed Setting
  • Extensive-Form Games

Challenges

Despite a general model with broad applications, MARL suffers from several challenges in theoretical analysis, in addition to those that arise in single-agent RL.

  1. Non-Unique Learning Goals - Unlike single-agent RL, where the goal of the agent is to maximize the long-term return efficiently, the learning goals of MARL can be vague at times. ...Indeed, the goals that need to be considered in the analysis of MARL algorithms can be multi-dimensional ... is undoubtedly a reasonable solution concept in game theory, under the assumption that the agents are all rational, and are capable of perfectly reasoning and infinite mutual modeling of agents. However, with bounded rationality, the agents may only be able to perform finite mutual modeling
  2. Non-Stationarity - multiple agents usually learn concurrently, causing the environment faced by each individual agent to be non-stationary. In particular, the action taken by one agent affects the reward of other opponent agents, and the evolution of the state. As a result, the learning agent is required to account for how the other agents behave and adapt to the joint behavior accordingly. This invalidates the stationarity assumption for establishing the convergence of single-agent RL algorithms
  3. Scalability Issue - To handle non-stationarity, each individual agent may need to account for the joint action space, whose dimension increases exponentially with the number of agents. This is also referred to as the combinatorial nature of MARL
  4. Various Information Structures - Compared to the single-agent case, the information structure of MARL, namely, who knows what at the training and execution, is more involved. For example, in the framework of Markov games, it suffices to observe the instantaneous state st , in order for each agent to make decisions

AI Agent Optimization

Agent optimization involves combining various elements like Prompt Engineering (PE), Human-in-the-Loop (HITL) Learning, and critique mechanisms to create highly advanced bots capable of completing tasks in natural language. These components include memory repositories to remember actions taken, critique algorithms for error correction, and orchestration software that combines LLMs with tools for optimal performance.

Critique mechanisms are crucial for the development of autonomous AI agents that can handle complex tasks efficiently and continuously improve their performance. By incorporating the following components and mechanisms into the design and development of AI agents, organizations can create autonomous systems that continuously self-assess and refine their outputs, leading to improved performance and efficiency over time. To build critique mechanisms in AI agents, particularly focusing on self-critique or auto-critique, the following steps are crucial based on the provided search results:

  • Auto-Critique Process: Implement an autonomous process where AI agents reflect on past responses and errors to improve their output without human intervention. This involves drawing on new input from various sources like external tools, other agents, affiliated LLMs, and heuristic functions.
  • Self-Criticism Process: In contrast, self-criticism is an internal feedback process where the AI evaluates its own responses, leading to immediate and iterative refinement. ChatGPT, for example, employs transformer-based neural networks and attention mechanisms to reassess and improve its outputs based on prompts. The use of self-criticism in AI tools empowers non-technical users, enhances versatility by creating multiple agents for different roles, and proves cost-effective by saving manual refining costs. This continuous loop of generating, evaluating, and revising output ensures a higher standard of response quality with each iteration.
  • Stop Conditions: Define stop conditions that allow the AI agents to finalize their output once they reach a sufficient result based on predefined metrics for evaluating self-reasoning.
  • Memory Repositories: Incorporate memory repositories within the AI agents to remember past actions taken, enabling them to learn from experiences and improve over time.
  • Error Correction Algorithms: Integrate auto-critique algorithms within the AI agents to enable them to correct mistakes along the way, ensuring continuous improvement in their outputs.
  • Orchestration Software: Combine Large Language Models (LLMs) with memory, tools, and auto-critique algorithms to create highly advanced bots capable of completing assigned tasks in natural language.
  • Observability & Monitoring process: process ensures the correctness, reliability, and effectiveness of AI models by providing visibility into the AI's behavior and performance across their lifecycle.

Critique Frameworks

Some frameworks for self-critique and auto-critique mechanisms in AI agents include:

  • CRITIC Reflexion: A framework that focuses on improving the agent's performance and robustness through self-critique, AI feedback, and synthetic data generation.
  • SLAPA: A framework that involves self-critiquing models to assist human evaluators in refining AI outputs.
  • ReACT: A framework that emphasizes improving the agent's performance and robustness through self-critique, AI feedback, and synthetic data generation.
  • Chain of Hindsight: A method that enhances the self-criticism process by providing sequential context to AI agents, enabling them to refine outputs in a contextually relevant manner.
  • ART (Auto-Critique Reflexion Technique): An autonomous process that allows agents to improve and amend their own output by reflecting on past responses and errors without human intervention.
  • APE (Auto-Critique Prompt Engineering): Involves forming and refining natural language statements and questions to achieve optimal AI performance through self-critique mechanisms.

Observability & Monitoring Frameworks

Some frameworks for Observability & Monitoring Frameworks in AI Agents include:

  • Arthur: A comprehensive AI observability platform that provides insights into model behavior, data, and performance across its lifecycle, enabling precise root cause analysis of predictions made by ML models.
  • Honeyhive: A framework that focuses on monitoring, analyzing, and visualizing the internal states, inputs, and outputs of AI models to ensure correctness, reliability, and effectiveness.

  • Promptmetheus: Focuses on enhancing the transparency of AI agents by providing insights into the factors influencing decision-making processes through techniques like model interpretability and feature importance analysis.


Curse of Optimization

There's nothing really insightful or interesting about just doing objective optimization. We've got plenty of good algorithms for doing that and it's not counterintuitive at all. It totally makes sense, but it's not going to get us hardly anywhere. Interesting whatsoever. It's kind of the curse of optimization And what that means is when you build an optimization system, you have to take a metric. You have to take a utility function or a cost function, and you have to optimize it, but then it suffers from the shortcut rule and good hot law. The shortcut rule is that you get what you optimize for exactly what you up to my support and nothing else, which means if you can't specify all of the richness and complexity that you want to capture in the cost function, then it's all gone. Then, good hearts law is this very interesting idea that when a target becomes a measure, it ceases to become a good measure, which means many of the systems. We design, including current social networks are divorced of all of the richness and creativity which exists in the real world. We need to create systems that capture the creative generative processes, which exist in our physical and social worlds. And with naïve objective optimization, it's impossible In my opinion, the reason why ChatGPT is the antithesis of creativity is its design to reduce entropy. It's designed to make things simple. Whereas a creative process is about producing new information. So there's a tug of war with things like GPT, which are centralized, because we have access to creativity, we have access to serendipitous novelty, and we can put it into gpt, but GPT is always pushing back on us. It wants to make things simple. This is model bias in order to produce a truly creative process, we need to design platforms which eliminate this centralizing force. - Kenneth O. O. Stanley

Stanley and Lehman begin with a surprising scientific discovery in artificial intelligence that leads ultimately to the conclusion that the objective obsession has gone too far. They make the case that great achievement can't be bottled up into mechanical metrics; that innovation is not driven by narrowly focused heroic effort; and that we would be wiser (and the outcomes better) if instead we whole-heartedly embraced serendipitous discovery and playful creativity.
