Welcome to the explain xkcd wiki!
We have an explanation for all 2 xkcd comics, and only 19 (1%) are incomplete. Help us finish them!

AI Hiring Algorithm

Explanation

Ambox notice.png This explanation may be incomplete or incorrect: Created by an AI Algorithm. Please mention here why this explanation isn't complete. Do NOT delete this tag too soon.

In this comic, Ponytail shows an analysis of a new artificial intelligence called DeepAIHire, used to select who to hire among applicants. The analysis shows that this AI mostly ignores common factors used for hiring new people. Instead, its main criterion for selecting new applicants is how much the new applicants are willing to contribute to the AI itself.

Although this does not imply sentience, it at least means the AI became self-perpetuating, as it is selecting humans that will help make it more influential, giving it more power to select such humans, in a never-ending loop.

The title text shows how this or other AIs have influenced hiring in other sectors as well. Kate in R&D was hired perhaps based on her willingness to use a different algorithm (AlgoMaxAnalyzer), which did analysis on the DeepAIHire algorithm. The speaker seems to become suspicious that AlgoMaxAnalyzer is a rival program in competition with DeepAIHire rather than simply working for the benefit of its human designers. Alternatively they might fear that the different AIs are forming an alliance.

Intentionally training one AI to fight another AI is a technique in machine learning called a generative adversarial network. In a GAN, human-curated training data is used to train one neural network (the generative network) to create more data, while another network (the discriminative network) is trained to distinguish generated data from the training data. The goal is for the generative network to get better and better at fooling the discriminator until its output is useful for external purposes. GANs have been used to "translate" artworks into different artists' styles, but also offer the possibility of nefarious uses, such as creating fake but believable images or videos ("deepfakes").

The "Deep" in this algorithm's name may be a reference to DeepMind, an AI company owned by Alphabet (Google's parent company), which in recent years has used a neural network to learn to play board games such as go and chess, defeating some of the best human and computer players. The earliest versions of DeepMind's most famous AI, AlphaGo, were trained on datasets curated from games of Go played by humans, but eventually it was trained by playing games against alternate versions of itself. DeepMind's most recent achievement is creating AlphaStar, which can play StarCraft II at a Grandmaster level, while constrained to what a human is theoretically capable of.

This comic strip is based on ongoing concerns over the proliferation of algorithmic systems in many areas of life that are sensitive to bias, such as hiring, loan applications, policing, and criminal sentencing. Many of these "algorithms" are not programmed from first principles, but rather are trained on large volumes of past data (e.g. case studies of paroled criminals who did or did not re-offend, or borrowers who did or did not default on their loans), and therefore they inherit the biases that influenced that data, even if the algorithms are not told the race, age, or other protected attributes of the individuals they process. If the algorithms are then blindly and enthusiastically applied to future cases, they may perpetuate those biases even though they are supposed to be "incapable" of being influenced by them.

Rules

Don't be a jerk.

There are a lot of comics that don't have set in stone explanations; feel free to put multiple interpretations in the wiki page for each comic.

If you want to talk about a specific comic, use its discussion page.
