Superposition Research Is Actually Quite Old
ninamiolane · x · 2026-07-15
This post points out that research on superposition (feature superposition) has actually been ongoing for over thirty years, with early related work dating back to Smolensky 1990.
The core idea is that this research lineage can be understood as:
- Performing sparse feature learning on top of distributed/neural representations;
- Combined with interpretability evaluations to understand these representations;
- This isn't a development from just the last two years, but rather has a long history.
The poster emphasizes this is just an incomplete list of literature leads, simply taking the time to reconnect this long-term research thread.
