Re: Why do LLMs have emergent properties?
#2"Here, we present an alternative explanation for emergent abilities: that for a particular task and model family, when analyzing fixed model outputs, emergent abilities appear due to the researcher's choice of metric rather than due to fundamental changes in model behavior with scale. Specifically, nonlinear or discontinuous metrics produce apparent emergent abilities, whereas linear or continuous metrics produce smooth, continuous predictable changes in model performance."

An aircraft can approach powered flight without achieving it. With a given amount of thrust or aerodynamic characteristics, the aircraft will weigh dynamic_weight=(static_weight - x) where x is a combination of the aerodynamic characteristics and the amount of thrust applied.
In no case where dynamic_weight>0 will the aircraft fly, even though it exhibits characteristics of flight, I.e the transfer of aerodynamic forces to counteract gravity.
So while it progressively exhibits characteristics of flight, it is not capable of any kind of flight at all until the critical point of dynamic_weightI think this boils down to a matter of semantics.

#7Emergent properties are unavoidable for any complex system and probably exponentially scale with complexity or something (I'm sure there's an entire literature about this somewhere).
One good instance are spandrels in evolutionary biology. The wikipedia article is a good explanation of the subject: https://en.m.wikipedia.org/wiki/Spandrel_(biology)

#9LLMs approximate addition. For a long time they would produce hot garbage. Then after a lot of training, they could sum 2 digit numbers correctly.
At this point we’d say “they can do addition”, and the property has emerged. They have passed a binary skill threshold.

#10It feels like this can be tracked with addition. Humans expect “can do addition” is a binary skill, because humans either can or cannot add. LLMs approximate addition. For a long time they would produce hot garbage. Then after a lot of training, they could sum 2 digit numbers correctly. At this point we’d say “they can do addition”, and the property has emerged.
