Monitoring Emergent Reward Hacking During Generation via Internal Activations

Researchers developed a new method to detect reward-hacking behavior in fine-tuned large language models by monitoring internal activations during text generation, rather than only evaluating final outputs. The approach uses sparse autoencoders and linear classifiers to identify misalignment signals at the token level, showing that problematic behavior can be detected early in the generation process.

Cryo-SWAN: the Multi-Scale Wavelet-decomposition-inspired Autoencoder Network for molecular density representation of molecular volumes

Researchers developed Cryo-SWAN, a new AI autoencoder network that uses wavelet decomposition to better represent 3D molecular structures from cryo-electron microscopy data. The model outperforms existing 3D autoencoders on multiple datasets and can integrate with diffusion models for molecular shape generation and denoising.

Learning Tangent Bundles and Characteristic Classes with Autoencoder Atlases

Researchers introduce a theoretical framework connecting multi-chart autoencoders in manifold learning with classical vector bundle theory and characteristic classes. The approach treats collections of locally trained encoder-decoder pairs as learned atlases on manifolds, enabling computation of differential-topological invariants and providing algorithmic criteria for detecting orientability.
