The Future of AI: Building Intelligent Systems

Artificial intelligence (AI) is revolutionizing various fields, from ICT to robotics. However, there are still significant challenges in harnessing the full potential of AI. In this article, we will explore the architecture of AI systems and the obstacles that AI faces, particularly in acquiring common sense. We will Delve into the nuances of supervised and unsupervised learning, and discuss the possibilities offered by reinforcement learning and generative adversarial training. By the end of this article, You will have a better understanding of how we can design "Honey Function Jenna" - an AI system that aligns its values with ours. Let's dive in!

1. Introduction

AI systems consist of three basic modules: the perceptual module, the agent module, and the objectives module. The perceptual module enables the agent to estimate the state of the world, while the agent module generates action sequences to act upon the world. The objectives module defines the agent's internal state and drives its actions Based on hardwired objectives. However, for AI systems to exhibit true intelligence and common sense, they need the ability to predict and learn from unobserved data.

2. The Architecture of an AI System

The architecture of an AI system mimics the structure of the human brain. The perceptual module allows the AI agent to perceive the state of the world, while the agent module generates actions based on the perceived state. The objectives module, composed of immutable and trainable components, drives the agent's behavior by minimizing a predefined objective. Additionally, the agent requires a prediction module to enable planning, reasoning, and working memory. This architecture lays the foundation for AI systems to learn and adapt.

3. The Obstacles of AI Wave

One of the major obstacles AI faces is acquiring common sense. Unlike Current achievements in supervised learning, where AI agents learn from labeled data, common sense is primarily acquired through unsupervised learning. Humans, and even animals, learn basic principles of the world by observing and interacting with it. This observational learning allows us to build a mental model of the world, enabling prediction and the development of common sense.

4. The Necessity of Unsupervised Learning

While supervised learning has its successes, such as image labeling and autonomous driving in controlled environments, it falls short when it comes to True AI. Unsupervised learning, on the other HAND, offers the potential for machines to acquire common sense and predictive capabilities. Reinforcement learning, a form of unsupervised learning, poses challenges due to the high sample complexity required to learn. However, recent advancements, such as generative adversarial training, Show promise in training AI systems to generate realistic outputs.

5. Designing a Honey Function Jenna

To Align AI systems with our values, we need to design their objective functions. One approach is to hardwire a safeguard objective that ensures the system's behavior aligns with our intentions. However, this approach may not capture the nuances of complex situations. An alternative is to train the objective function through inverse reinforcement learning, where the AI system learns from both human trainers and its own actions. This data-driven approach allows the AI system to discern the objectives of the trainers and adopt those objectives as its own.

6. Conclusion

AI is rapidly advancing, but challenges remain in building truly intelligent and common-sense AI systems. The architecture of an AI system, comprising perceptual, agent, objective, and prediction modules, provides a framework for learning and adaptation. Unsupervised learning, particularly through generative adversarial training, offers possibilities for AI systems to acquire common sense and improve predictive capabilities. By designing objective functions, be it through hardwiring or training, we can Shape AI systems that align with our values. As the field of AI continues to evolve, the future holds immense potential for creating intelligent systems that enhance human life.
