François Chollet: How We Get To AGI

YouTube

* Two types of abstractions
- Type-1: prototype/value-centric, continuous — transformer is good at this
- Type-2: program-centric abstraction/graphs, discrete/search — ???
- Type-2 is data efficient but test-time inefficient due to combinatorial explosion.

* Intelligent systems needs to combine Type-1 and 2 abstractions
- Type-2 can be guided by type-1
- Need global library of abstract subroutines

* The evolution of ARC benchmarks
- ARC-1: Prior-free reasoning tasks
- ARC-2: Compositional reasoning tasks
- ARC-3: Reasoning with interactive agency

* Intelligence implementation requires two components
- Abstraction acquisition
- Abstraction recombination (application)

François Chollet, creator of Keras and the ARC suite of AGI benchmarks, gave a very thoughtful talk on how we can actually get to #AGI:

* Intelligence is a process, not skills
- Intelligence is an efficient conversion from past experience to potential operating area
- AGI is not about automation, it’s about invention

* Three characterstics of intelligence
- Fluid intelligence
- Broad operational area
- Information-efficient program acquisition and synthesis

Abstract rule learning promotes cognitive flexibility in complex environments across species

Abstract rule learning promotes cognitive flexibility in complex environments across species - Nature Communications

Whether neurocomputational mechanisms that speed up human learning in changing environments also exist in other species remains unclear. Here, the authors show that both rats and humans sequentially test different abstract hypotheses to infer rules.

Thank you, Nina Kuscsik.

Temperature at 8am was ~55F, and was ~74F when I finished. Directly under the sun with no cloud or shade added another 5-10F. But I should not complain compared to many other geolocations! Getting used to heat hopefully will help me in my coming marathon race in August.

As promised this #LongRunSunday I didn't run a 50+K like the past two Sundays, just a (mostly) Z2 #marathon 🤪 -- running around #LakeSammamish and visiting the troll in #Issaquah! Moving time 3:53:26 pace 8'54"/mi.

I stopped at parks for photos and McDonald's at midpoint for coffee and apple pie, as usual.

Morning run

13km road and tracks. A glorious morning, threatened to rain but we only encountered a short fall towards the end of it. Now for breakfast and a swim.
