What is AI Safety?

by Stephen M. Walker II, Co-Founder / CEO

What is AI Safety?

AI Safety is an interdisciplinary field that focuses on preventing accidents, misuse, or other harmful consequences that could result from artificial intelligence (AI) systems. It involves technical aspects such as ensuring the robustness, assurance, and specification of AI systems, as well as policy considerations like assigning individual human accountability for the safety of an AI algorithm.

AI Safety also involves developing norms and policies that promote safety. This includes creating deterministic algorithms for oversight and sanity-checking, detaching AI from direct control systems, and incorporating human oversight in AI operations to address unexpected situations.

Organizations like the Center for AI Safety (CAIS) and the U.S. Artificial Intelligence Safety Institute are actively working on AI Safety research and advocating for safety standards. They offer resources and programs to support progress and innovation in AI safety, and work on reducing societal-scale risks associated with AI.

What is the difference between robustness, assurance, and specification in AI safety?

Robustness, assurance, and specification are three core elements of AI Safety, each addressing different aspects of the safe operation and behavior of AI systems.

  1. Robustness — This refers to the ability of an AI system to function reliably and accurately under a variety of conditions, including those that are unfamiliar or adversarial. A robust AI system is designed to withstand adversarial attacks, perturbations, data poisoning, and undesirable reinforcement. It emphasizes the system's integrity and the soundness of its operations, even under harsh conditions.

  2. Assurance — Assurance is about the ability to understand and control AI systems. It involves creating mechanisms to confirm and validate the behavior of AI systems. Assurance seeks to establish that an AI system can be analyzed and understood easily by human operators. It involves mastering the functional insufficiencies of the AI components and the often unknown influences of the data.

  3. Specification — Specification involves defining the goals and constraints of an AI system in a way that aligns with human values and ethical principles. It's about ensuring that the AI system behaves as intended and aligns with the system designer's intentions. Specification is crucial because AI is often used for complex tasks, making an exhaustive specification unfeasible.

Robustness is about the resilience of an AI system under various conditions, assurance is about understanding and controlling the AI system, and specification is about defining the system's behavior in alignment with human values and intentions.

Is AI Safety like Gun Safety, it's about stopping nefarious actors?

AI safety is a multifaceted field that encompasses more than just preventing nefarious actors from misusing AI systems. While the analogy to gun safety in terms of preventing misuse by malicious individuals is relevant, AI safety also includes ensuring that AI systems operate safely and reliably in a broad range of scenarios, including accidental failures and unintended consequences of their use.

AI safety research can be grouped into three main categories: robustness, assurance, and specification. Robustness involves making sure AI systems continue to operate safely even when faced with unfamiliar situations or when being targeted by adversaries who may attempt to manipulate or trick the system. Assurance is about building trust in AI systems by making them interpretable and explainable, so that humans can understand and predict their behavior. Specification involves defining the goals and behaviors of AI systems in a way that aligns with human values and prevents harmful outcomes.

The use of AI for gun detection in schools is an example of how AI can be applied to enhance safety and prevent violence. Companies like ZeroEyes use computer vision AI to detect visible guns in camera feeds and alert authorities before shots are fired, aiming to be proactive rather than reactive. However, this technology is not foolproof and cannot detect concealed weapons, highlighting the importance of robustness in AI safety.

AI safety is not only about individual systems but also about global solutions that implement safety measures across all AI applications. It involves interdisciplinary efforts, including machine ethics and AI alignment, to ensure that AI systems are moral and beneficial. Moreover, AI safety is not just a technical issue but also involves policy considerations and the development of norms to promote safe deployment and operation.

What's the difference between AI Safety and AI Alignment?

AI Safety and AI Alignment are two closely related but distinct concepts in the field of artificial intelligence.

AI Safety refers to the broad endeavor to ensure that AI systems operate safely and reliably, minimizing the risk of harm to humanity. It focuses on technical solutions to ensure that AI systems operate within safe limits even in unfamiliar situations, and that they are robust, interpretable, and their goals and behaviors are well-specified. AI Safety also includes considerations of misuse, robustness, reliability, security, privacy, and other areas.

On the other hand, AI Alignment is a specific area of AI Safety research that aims to ensure that AI systems' goals, preferences, or ethical principles align with those of humans. It involves encoding human values and goals into AI systems to make them as helpful, safe, and reliable as possible. The challenge lies in the dynamic nature of human values and preferences, which means that alignment solutions must also adapt dynamically.

In essence, while AI Safety is about ensuring that AI systems do not cause harm and operate within safe limits, AI Alignment is about ensuring that the goals of AI systems align with human values and preferences. Both are crucial for the responsible development and deployment of AI systems.

What are the challenges of AI Safety?

AI Safety encompasses several challenges:

  1. AI Alignment Problem — This involves aligning AI with human values, goals, and social norms. It's about ensuring that AI systems are reliably aligned with human values.

  2. Data Quality and Corruption — AI systems can be compromised by poor data quality or corrupted data, leading to unreliable or harmful outcomes.

  3. Debugging — Debugging AI systems can be challenging due to their complexity and the black-box nature of many AI algorithms.

  4. Reward Hacking — A reinforcement learning algorithm learns through “rewards”. If these rewards are not properly aligned with desired outcomes, the AI system may learn to behave in undesirable ways.

  5. Biased Training Set — If the data used to train an AI system is biased, the system's outputs will also be biased.

  6. Data Scarcity and Unlabeled Data — AI systems require large amounts of data to learn effectively. Lack of data, or data that is not properly labeled, can hinder the system's ability to learn.

  7. Data Privacy — AI systems often handle sensitive data, and ensuring this data is used and stored securely is a major concern.
