µPC: Scaling Predictive Coding to 100 Layer Networks (arxiv.org)
The biological implausibility of backpropagation (BP) has motivated many alternative, brain-inspired algorithms that attempt to rely only on local information, such as predictive coding (PC) and equilibrium propagation. However, these algorithms have notoriously struggled to train very deep networks, preventing them from competing with BP in large-scale settings. Indeed, scaling PC networks (PCNs) has recently been posed as a challenge for the community (Pinchetti et al., 2024).

Tied Crosscoders: Tracing How Chat LLM Behavior Emerges from Base Model (lesswrong.com)
We are interested in model-diffing: finding what is new in the chat model when compared to the base model. One way of doing this is training a crosscoder, which would just mean training an SAE on the concatenation of the activations in a given layer of the base and chat model. When training this crosscoder, we find some latents whose decoder vector mostly helps reconstruct the base model activation and does not affect the reconstruction for the chat model activation.
