Recursive Self-Improvement refers to the property of making improvements on one's own ability of making self-improvements. It is an approach to Artificial General Intelligence that allows a system to make adjustments to its own functionality resulting in improved performance. The system could then feedback on itself with each cycle reaching ever higher levels of intelligence resulting in either a hard or soft AI takeoff.

An agent can self-improve and get a linear succession of improvements, however if it is able to improve its ability of making self-improvements, then each step will yield exponentially more improvements then the previous one.

Recursive self-improvement and AI takeoff

Recursively self-improving AI is considered to be the push behind the intelligence explosion. While any sufficiently intelligent AI will be able to improve itself, Seed AIs are specifically designed to use recursive self-improvement as their primary method of gaining intelligence. Architectures that had not been designed with this goal in mind, such as neural networks or large "hand-coded" projects like Cyc, would have a harder time self-improving.

Eliezer Yudkowsky argues that a recursively self-improvement AI seems likely to deliver a hard AI takeoff – a fast, abruptly, local increase in capability - since the exponential increase in intelligence would yield an exponential return in benefits and resources that would feed even more returns in the next step, and so on. In his view a soft takeoff scenario seems unlikely: "it should either flatline or blow up. You would need exactly the right law of diminishing returns to fly through the extremely narrow soft takeoff keyhole."1.

Yudkowsky argues that there are several points which seem to support the hard takeoff scenario. Some of them are the fact that one improvement seems to lead the way to another, hardware overhang and the fact that sometimes- when navigating through problem space - one can find a succession of extremely easy to solve problems. These are all reasons for suddenly and abruptly increases in capability. On the other hand, Robin Hanson argues that there will be mostly a slow and gradual accumulation of improvements, without a sharp change.
