Artificial Intelligence Understands by Not Understanding

The secret to writing a program for a sympathetic chatbot is surprisingly simple…

I’ve been reviewing philosopher and programmer Erik Larson’s The Myth of Artificial Intelligence. See my two earlier posts, here and here. With natural language processing, Larson amusingly retells the story of Joseph Weizenbaum’s ELIZA program, in which the program, acting as a Rogerian therapist, simply mirrors back to the human what the human says. Carl Rogers, the psychologist, advocated a “non-directive” form of therapy where, rather than tell the patient what to do, the therapist reflected back what the patient was saying, as a way of getting the patient to solve one’s own problems. Much like Eugene Goostman, whom I’ve already mentioned in this series, ELIZA is a cheat, though to its inventor Weizenbaum’s credit, he recognized from the get-go that it was a cheat.…

AI Can Fight COVID by Detecting Changes in Virus “Language”

One research team is experimenting with natural language processors (NLP), used to analyze human speech, to detect similar virus mutations

One strategy in the fight against COVID-19 relies on the curious fact that genetics is actually a language. Genome sequencer Francis Collins has even called it The Language of God. More practically, AI programs that act as natural language processors can help catch deadly coronavirus mutations. The same strategies the AIs use for reading sentences can be used to read the virus’s attempts to escape destruction by mutations: Galileo once observed that nature is written in math. Biology might be written in words. Natural-language processing (NLP) algorithms are now able to generate protein sequences and predict virus mutations, including key changes that help the coronavirus evade the immune system. The key insight making this possible is that many properties of…
