Imagine a world where your car drives you to work, your doctor is a machine, and your financial advisor is an algorithm. This is not the plot of a sci-fi movie; it is the reality we are stepping into, thanks to advancements in Artificial Intelligence (AI) technologies like Machine Learning (ML) and Deep Learning (DL). These technologies are on track to dominate the global market, with projections reaching USD 225.91 billion by 2030. At this crossroads, a crucial question emerges: What happens when these AI-based systems fail, as with greater reliance on AI comes greater responsibility? Take, for instance, the tragic Tesla crash in Guangdong, China, which resulted in two fatalities and three injuries. Such incidents show us why it is important to look closely at the flaws of AI-based systems, particularly since even our most advanced AI systems are imperfect and susceptible to unknown risks.
The exploration of AI software bugs starts with the basic idea of a software bug: a mistake or defect that causes a program to work incorrectly or not as expected. Like most computer science majors, my understanding of software bugs was once confined to the traditional faults and errors in the software system. However, when I moved from studying traditional software to focusing on AI-based software during my PhD in 2021, I found that bugs in AI-driven systems are a whole different story. These bugs do not just come from coding mistakes. For instance, AI-based systems fundamentally rely on data, and thus, the quality of this data is crucial. Inaccuracies or other data-related issues can directly result in errors within these systems. Additionally, AI computations are resource-intensive, necessitating specialized hardware, such as Graphics Processing Units (GPUs), to expedite processing. However, faults in the hardware, or mismatches between the hardware and software, can further contribute to the malfunctioning of AI systems.
Understanding the nature of AI software bugs requires a shift from the general to the specific, transitioning from conventional software errors to the distinct challenges AI systems introduce. Consider this scenario: A smart home security system that falsely identifies family members as intruders due to a bug in its facial recognition technology. This issue results in false alarms resulting from inadequate testing in varied lighting conditions. Recent research has shed light on various types of AI software bugs, offering a clearer picture of the symptoms, root causes, and characteristics of these bugs. Despite progress in understanding and categorizing AI bugs, traditional software error-handling methods often fall short for AI-based systems due to the unique nature of AI bugs, highlighting a significant gap in our current approaches. As technologies make decisions affecting our lives and world, we need to ensure they get it right! This necessitates not only innovative methods tailored specifically to AI’s challenges but also a collective effort to enhance the safety and reliability of these systems.
Join me in this blog series as I guide you through the challenges of AI-driven systems and the concept of AI bugs – glitches in the matrix! We will dive deep into the often-overlooked complexities of AI bugs, discuss research findings, think through new strategies for addressing these bugs, and improve the reliability of AI systems. By the end, I hope you will see why reliable, trustworthy AI matters for its real-world applications.
