Researchers from the University of Washington and the University of Hong Kong have proposed a human-like generative agent system that mimics human behavior. The system uses a two-system mechanism, inspired by human psychology, to guide generative agents and introduces aspects like basic needs, emotions, and social relationships to influence their behavior. The agents interact with each other and receive negative feedback when they fail. The researchers have created a game interface to visualize and monitor the agents’ behavior.
Introducing Human-like Generative Agents for Natural and Engaging User Interactions
Human-like generative agents are powerful tools used in chatbots and virtual assistants to provide natural and engaging user interactions. These agents can understand and respond to user queries, engage in conversations, and perform tasks like answering questions and making recommendations. They are built using advanced natural language processing (NLP) techniques and machine learning models, such as GPT-3, to produce coherent and contextually relevant responses.
These agents have practical applications in various fields. For example, they can enhance the gaming experience by creating interactive stories, dialogues, and characters in video games or virtual worlds. They can also assist writers and creatives in brainstorming ideas, generating story plots, or even composing poetry or music.
Improving Human-like Behavior with Humanoid Agents
To make generative agents behave more like humans, researchers at the University of Washington and the University of Hong Kong have proposed the use of humanoid agents. These agents are guided by a two-system mechanism inspired by human psychology, where system 1 handles intuitive and effortless thinking, and system 2 handles logical thinking.
The behavior of these agents is influenced by aspects like basic needs, emotions, and the closeness of their social relationships with other agents. They interact with others and receive negative feedback, such as loneliness, sickness, and tiredness, when they fail to do so.
The social brain hypothesis suggests that a significant part of our cognitive ability has evolved to track the quality of social relationships. To mimic this behavior, the researchers empower humanoid agents to adjust their conversations based on their closeness to one another. They visualize these agents using a Unity WebGL game interface and present their statuses over time using an interactive analytics dashboard.
Practical Implementation and Considerations
To create a sandbox HTML game environment for visualizing humanoid agents, the researchers use the Unity WebGL game engine. Users can select from different worlds to see the agent’s status and location at each step. The status of various humanoid agents over time is visualized using Plotly Dash.
It’s important to note that the current system supports dialogues between only two agents and is aimed at facilitating multi-party conversations. Users should be informed that they are working with a simulation that may not perfectly reflect human behavior in the real world.
While human-like generative agents have numerous capabilities, it’s crucial to consider ethical and privacy concerns. These include the potential for spreading misinformation, biases in the training data, and responsible usage and monitoring.
