Introducing The Darwin Gödel Machine sakana.ai/dgm The Darwin Gödel Machine is a self-improving agent that can modify its own code. Inspired by evolution, we maintain an expanding lineage of agent variants, allowing for open-ended exploration of the vast design space of such self-improving agents.

“Continuous Thought Machines” Blog → sakana.ai/ctm Modern AI is powerful, but it's still distinct from human-like flexible intelligence. We believe neural timing is key. Our Continuous Thought Machine is built from the ground up to use neural dynamics as a powerful representation for intelligence.

Neural Attention Memory Models are evolved to optimize the performance of Transformers by actively pruning the KV cache memory. Surprisingly, we find that NAMMs are able to zero-shot transfer its performance gains across architectures, input modalities and even task domains! arxiv.org/abs/2410.13166

3) Optimizer optimization: Think hyperparameter tuning, e.g., learning rate etc. The search within the inner-loop is altered. We use meta-learning to achieve improved inner-loop optimization, so it is well worth considering exactly how our double-loop achieves this! #meta-learning #deeplearning #ai

Joachim W Pedersen @joachimwpedersen.bsky.social · 04/12/2024
1) Starting point optimization: Think MAML. Move the initial point of the inner-loop search to a better place to learn quick. 2) Loss landscape optimization: Think neural architecture search. The loss landscape(s) of the inner-loop is transformed.

Joachim W Pedersen @joachimwpedersen.bsky.social · 04/12/2024
This can be thought of independently from which optimizer is being used in the inner-loop. In any meta-learning approach, the outer-loop optimization will transform the inner-loop optimization process in at least of one three ways and often in a combination of these three.

Joachim W Pedersen @joachimwpedersen.bsky.social · 04/12/2024
In deep learning research, we often categorize meta-learning approaches as either gradient-based or black-box meta-learning. In my PhD thesis, I argued that it can sometimes be useful to classify approaches based on how the outer-loop optimization affects the inner-loop optimization.

In the same vein of NDPs: arxiv.org/pdf/2405.08510 A have also been interested in synaptic plasticity for a while ( arxiv.org/pdf/2104.07959 ) and how plasticity can be used to achieve structural flexibility in neural networks: dl.acm.org/doi/pdf/10.1...

Thanks! Culture is definitely an accelerator, but still leaves some questions: Isn't the ability to outsmart adversaries always adaptive whether they are part of your species or not? And if culture is what made humans so smart, why are sophisticated cultures not more widespread in evolution?

So is high intelligence with a wide capacity of learning and abstracting only worth it in some niches and not generally adaptive? What do you all think? And what are some good resources to learn more about these arguments? n/n
000
Joachim W Pedersen @joachimwpedersen.bsky.social · 17/11/2024
Counter point to that is that even today, in the world of insects there are species that are arguably as successful as humans, and there is currently nothing that suggests that e.g. ants or termites are on a trajectory to abstract thought.

Joachim W Pedersen @joachimwpedersen.bsky.social · 17/11/2024
Another point could be that on a longer time span, high intelligence will actually be a dominating trait for 99 % of time. If it is a trait that is here to stay, then in a few billion years the era without abstract thought could seem like a small blip.

Joachim W Pedersen @joachimwpedersen.bsky.social · 17/11/2024
Obviously more complexity takes longer time to evolve, larger brains require more energy, etc. But pheno-plasticity is known to smoothen the loss landscape and brain anatomy across high and low intelligence species are similar enough to suggest they are not far from each other in the genome space.
