This article is a written version of a talk given at AI Dev World in october 2023
In an era where technology is advancing at an unprecedented pace, the prospect of achieving full automation has become a tantalizing goal. From intelligent assistants streamlining our daily tasks to complex AI systems shaping industries, the potential benefits are vast. However, it has become increasingly clear that the synergy between artificial intelligence and human operators holds the key to unlocking the true potential of these systems. Full automation is not the goal.
The essence of human capability lies in our innate ability to improvise and creatively navigate unforeseen challenges—a talent that artificial intelligence struggles to replicate. Moreover, societal trust and regulatory frameworks necessitate human involvement to establish clear accountability chains, particularly in critical systems such as defense, energy production, healthcare, and the food and medicine supply chain. This trust is rooted in the understanding that humans can exercise judgment and make decisions based on a nuanced understanding of context—a quality that AI systems currently lack. Additionally, the dark side of full automation emerges when considering the potential loss of skills in critical tasks. As an example, the 2000 Paris metro accident serves as a stark reminder of such dangers. In this accident, the reliance on automatic piloting systems left the human driver unprepared to manually control the train when needed, highlighting the risks associated with de-skilling human operators in the face of automation system malfunctions, whether caused by accidents or cyber attacks. The advent of AI-powered tools makes it imperative to strike a balance between automation and human involvement to mitigate risks, ensure adaptability, and maintain the resilience of our systems.
However, in the face of escalating complexity, the necessity for AI assistance becomes evident as humans grapple with a myriad of challenges. One key aspect is the deluge of data that accompanies the modern landscape, particularly in industries like renewable energy. Compared to traditional thermal power stations, the proliferation of renewable production sites and sensors overwhelms traditional analytical capacities. Moreover, the high volatility inherent in sectors such as renewable energy demands a level of adaptability beyond human capability alone, given the increasing interconnectedness of actors and the heightened reliance on unpredictable weather patterns. As global standards rise to meet the imperatives of sustainability, the demand for carbon-free sources intensifies, placing a strain on traditional human-driven methodologies. Furthermore, a skilled labor shortage, exemplified in the renewable energy sector, where both new and legacy actors vie for talent from the same pool, underscores the urgency of augmenting human capabilities with AI assistance. In this intricate landscape, the synergy between human intuition and AI prowess emerges as a potent force, enabling us to not only navigate complexity but to thrive amid the evolving challenges of our technological age.
At AI Redefined, we believe in the concept of superteams—a harmonious collaboration between AI agents and human minds, each contributing unique strengths to create a formidable force. Designing and implementing a superteam requires us to rethink the way we design AI systems and primarily center our choices around collaboration. In this article we will look at 4 main design pillars that contribute to building efficient superteams.
Systemic approach
From the inception of a system where an AI agent aids a human operator, a multi-agent system naturally emerges, with each agent representing a distinct decision-making entity. This design choice not only reflects the complexity of real-world scenarios but also introduces a host of benefits. The allocation of decision-making to multiple agents enables a more granular approach, where additional agents can be introduced to address specific components, fostering a modular and scalable architecture.
In practice, the advantages of a multi-agent system become evident as the design necessitates considering bidirectional signals from the outset. Beyond the conventional flow of information from AI to humans, the design requires thoughtful consideration of explicit, self-reported feedback from humans. Equally important is understanding how behavioral feedback from human operators can be incorporated into the system's decision-making loop. This bidirectional communication, rooted in a multi-role system architecture, facilitates seamless interaction between smaller, focused components, creating a dynamic interplay between AI and human decision-makers.
Shared experience training
Opting to train AI agents in tandem with human operators stands as our second design pillar. Human-in-the-Loop Learning (HILL) techniques enable the comprehensive training of the entire human/AI superteam. The advantages of this approach are numerous.
A first key benefit is significantly reducing both data requirements and training time. These critical aspects are highlighted in studies such our own paper "Human-AI Interactions in Real-World Complex Environments Using a Comprehensive Reinforcement Learning Framework," presented during AAMAS 2023 or one of the reference Reinforcement Learning with Human Feedback paper "Deep TAMER: Interactive Agent Shaping in High-Dimensional State Spaces", presented at AAAI 2018. Furthermore, the incorporation of human data during training has been proven instrumental in improving collaborative performance, as evidenced in the NeurIPS 2019 publication, "On the Utility of Learning about Humans for Human-AI Coordination.".
Crucially, the advantages of training together extend beyond the AI perspective, impacting the human experience within the collaborative framework. Studies like "Continual Learning for Instruction Following from Realtime Feedback," presented at NeurIPS in 2023, shed light on how training from interactive human data not only enhances trust and alignment but also empowers human operators to better leverage the capabilities of the AI agents.
This dual-benefit paradigm emphasizes the symbiotic relationship between AI and human entities, promoting a collaborative evolution that is not only efficient but also fosters a deeper understanding and alignment between the two decision-making entities.
Meaningful human control
The third foundational design pillar centers on the concept of meaningful human control, recognizing that merely placing humans in the loop is insufficient if their agency is diminished, reduced to a mere rubber stamp for AI decisions. To address this concern and uphold the principle of meaningful human control, a set of key considerations comes to the forefront.
Firstly, it is imperative to provide humans with sufficient information, presented in the most objective manner possible. Transparency and clarity in the information conveyed allow human operators to understand the rationale behind AI-generated decisions, fostering a sense of comprehension and trust in the system. Additionally, dynamic human-in-the-loop supervision becomes crucial, especially for critical decisions. This approach acknowledges the unpredictable nature of certain scenarios and ensures that human operators remain actively engaged in the decision-making process. Through dynamic supervision, humans can intervene when necessary, injecting their expertise and judgment into the system to guide it through complex situations.
Equally important is ensuring that human operators have access to diverse information and intervention modalities. This encompasses not only the availability of relevant data but also the tools and interfaces required for effective intervention. Enabling human operators to interact seamlessly with the system ensures that their control remains meaningful, allowing them to influence and shape decisions based on their expertise and understanding of the broader context.
In essence, the pursuit of meaningful human control acknowledges the need for humans to be active participants in the decision-making loop, armed with the information and tools necessary to contribute their unique insights and judgment. By embracing these principles, we construct systems that not only involve humans but empower them, fostering a collaborative and effective partnership between human operators and AI entities.
Continual learning
The fourth pivotal design pillar revolves around the concept of continual learning, recognizing the dynamic nature of environments and the evolving expectations placed upon AI systems. In an ever-changing landscape, the static deployment of AI assistants becomes inadequate, and the repetition of identical tasks risks alienating the users of the system. Therefore, crafting AI assistants that not only adapt to shifting contexts but also engage in continual learning as they are utilized becomes imperative.
A noteworthy example of this principle in action is illustrated by AIR’s collaboration with the confiance.ai consortium during the development of a prototype for human-driven quality control model fine-tuning. In this scenario, an AI agent collaborates with an operator to explore the vast space of training hyperparameters, with the ultimate goal of maximizing the operator's objectives. Crucially, the AI assistant undergoes continual learning by assimilating insights from the operator's behavioral feedback. This dynamic process enables the AI to progressively take shortcuts in repetitive tasks while maintaining human control, accommodating changes in objectives and ensuring the assistant evolves in tandem with the user's evolving needs.
This pattern of continual learning not only ensures that AI systems remain relevant in dynamic environments but also prevents the erosion of user engagement by alleviating the burden of repetitive tasks. By actively learning from human operators, the AI becomes a flexible and adaptive partner, enhancing its utility and effectiveness over time. In essence, the integration of continual learning into the design philosophy of AI assistants reinforces the commitment to building systems that evolve, learn, and align with the ever-shifting demands of their human collaborators.
Human-centered AI design
In conclusion, as we chart the course toward building efficient superteams of AI agents and human operators, we find inspiration in the words of Marot et al. in their paper, "Towards an AI Assistant for Power Grid Operators." They aptly highlight the evolving challenges faced by control rooms and the imperative of adapting to new scales of complexity without overwhelming human operators. The journey towards superteams requires a departure from the historical approach of incrementally adding applications and screens. Instead, as the authors do, we advocate for a paradigm shift, embracing a human-centered design philosophy where machines and operators co-adapt.
The four design pillars—systemic approach, shared experience training, meaningful human control, and continual learning—form the foundation of this paradigm. By fostering a modular and scalable architecture through a multi-agent system, we ensure adaptability to complex real-world scenarios. The integration of Human-in-the-Loop techniques in training not only enhances AI efficiency but also empowers human operators, fostering a symbiotic relationship. The principle of meaningful human control reinforces the importance of transparency, dynamic supervision, and diverse intervention modalities to keep humans at the forefront of decision-making. Finally, continual learning emerges as the dynamic force ensuring AI systems remain relevant and engaged with users, preventing the alienation caused by static deployments and repetitive tasks. As we embrace these design principles, we embark on a journey to redefine the future of AI collaboration—a future where human operators and AI entities co-evolve, co-adapt, and co-create, placing the human at the center of decisions.
At AI Redefined, our commitment to these principles is embodied in Cogment, our platform designed to train and orchestrate superteams. Cogment embraces a human-centered approach, facilitating meaningful collaboration between AI and human decision-makers. It's a testament to our belief that technology should empower, not replace, human capabilities.
