Check out this cool brain-inspired approach to self-supervised learning from @shahabbakht.bsky.social and crew!

🧠📈 🧪 #NeuroAI #MLSky
Preprint Alert 🚀

Can we simultaneously learn transformation-invariant and transformation-equivariant representations with self-supervised learning?

TL;DR Yes! This is possible via simple predictive learning & architectural inductive biases – without extra loss terms and predictors!

For understanding learning in neocortex 🧠, self-supervised learning 🤖 is interesting, but has several shortcomings.

Seq-JEPA is a step in the right direction. It learns by predicting sensory outcomes from series of interactions. Cool things emerged! 👇with @shahabbakht.bsky.social

The original work of the backpropagation: Rumelhart, Hinton & Williams, 1986 from PDP, not Nature. The Nature version is a conceptually digested version.

Writing a mathematical paper requires special skills of copying and pasting equations, not to mix up notations incorrectly. Logical compilers for math equations on the paper must be very useful. We don't run equations.

I have posted an arXiv paper (arxiv.org/abs/2501.11341) as a report, which guides the proofs of Lee and Seung (2000)'s multiplicative update algorithms to solve non-negative matrix factorization (NMF).

Lee and Seung (2000) introduced numerical solutions for non-negative matrix factorization (NMF) using iterative multiplicative update algorithms. These algorithms have been actively utilized as dimens...

The brain has certain way to understand the world, as different sentences that have equal information result in different understandability. The order of ideas matters. Their imaginability matters. Their accordance to our life matters.
