Causal AI

Causal AI is a subset of artificial intelligence (AI) that understands and incorporates the principles of cause and effect. Most AI systems can analyze large quantities of data and search for patterns. Many are capable of extrapolating from those patterns, creating accurate predictions. However, many AI systems do not look beyond their immediate dataset and question why they may be predicting certain results. Though it is still developing, causal AI will be able to examine datasets in new ways, including identifying bias. Causal AI may also be able to provide solutions and complete tasks in a manner that incorporates hypothetical situations that are not directly represented in the AI’s datasets.

Background

Those who work in the field of artificial intelligence (AI) create intelligent machines. To do this, they must create intelligent computer programs. Humans have worked toward the creation of truly intelligent machines since the invention of computers. However, the standards by which a machine can be considered intelligent have changed over time. In 1950, the famous computer scientist Alan Turing proposed that an intelligent program should be indistinguishable from a human operator when communicating through text. This AI milestone is known as the Turing Test. Some AI programs, including Google’s LaMDA and OpenAI’s ChatGPT, have been claimed by some to resemble human conversation. Despite this, some computer experts allege that these programs are not truly intelligent and have simply been trained to effectively mimic writing.

Forms of AI are used in many industries. Though people are still needed for many processes, AI can perform certain tasks faster and more efficiently than people. For example, AI can analyze large datasets and identify patterns faster than skilled human analysts and, in some cases, identify patterns that were never apparent to human analysts. Additionally, AI can perform repetitive, monotonous tasks with greater speed and accuracy than human workers. For these reasons, AI is ideal for interacting with large datasets and optimizing existing processes.

AI programs are commonly sorted into three categories based on their capabilities: narrow AIs, general AIs, and super AIs. Narrow AIs are created to perform a single task intelligently. They have a predefined list of functions and cannot expand beyond those capabilities. Despite these limitations, many narrow AIs have machine-learning capabilities, allowing them to become extremely effective at their intended tasks. Popular narrow AI functions include translation and image recognition software. Some AI systems, such as large language models, are highly effective at pattern recognition but have limits in understanding cause and effect.

General AI is capable of learning tasks, allowing it to apply knowledge and skills in innovative ways. If successfully implemented, general AI would be able to perform most of the tasks carried out by humans, potentially in more efficient or effective ways. However, the creation of a true general AI would require programmers to create a full set of cognitive abilities. For this reason, despite large sums of money being invested in researching the idea, scientists have yet to create a general AI.

Super AI is a potential evolution of general AI. It can perform all tasks that people can and many that people cannot. Super AI may one day be created from a general AI that learns to improve itself. Scientists theorize that a super AI could become so intelligent that humans are unable to comprehend its actions.

Overview

Causal AI refers to any AI that can explain and account for cause and effect within its calculations. Most AI being used by businesses utilizes predictive analytics, meaning that it uses data and statistical models to make predictions. However, despite recognizing patterns within a dataset and making predictions based on those patterns, the AI does not understand why any of these patterns may be occurring. Without this understanding, the AI is unable to take other circumstances into account when making its predictions. Industry reports have identified causal AI as an important approach for improving decision-making in business systems.

Some computer scientists consider causal reasoning to be one of the biggest hurdles that must be overcome to achieve more advanced forms of AI. To mimic the capabilities of a person, an AI must creatively determine the cause and effect of different parts of a single dataset. The computer must theorize as to why an interaction occurs instead of simply observing that a pattern exists. This might mean considering a variety of factors that may not be included in a dataset, such as relationships, socioeconomic status, dependencies, and medical histories. It may also involve asking “what if” questions to understand how different choices could change outcomes.

Though causal AI systems are still limited in capability, scientists theorize that causal AI could provide significant improvements in AI performance for businesses. For example, whereas a traditional AI can only extrapolate from a given dataset, a causal AI can ask broad questions regarding a business. These questions might include “Why are certain times of day busier than others?,” “Why are some customers leaving without making an order?,” and “Why are customer satisfaction levels low?” It can then use both its theories and predictions generated from its datasets to create viable solutions for the business. Causal AIs may be able to predict issues before they occur, allowing businesses to better prepare for future economic difficulties.

AI models sometimes use methods such as fault tree analysis (FTA), which was first designed by Bell Laboratories for the US Air Force in 1962. It uses a top-down approach that identifies the component failures that eventually lead to a larger system-level failure. Though it is still constructed of a series of logic gates, FTA allows analysts to pair the cause of an event with the event itself.
