The zero-error capacity of a noisy classical channel quantifies its ability to transmit information with absolute certainty, i.e., without any error. Unlike Shannon's standard channel capacity, which remains unaffected by pre-shared correlations, zer

Establishing Task Scaling Laws via Compute-Efficient Model Ladders

Autor: Bhagia, Akshita, Liu, Jiacheng, Wettig, Alexander, Heineman, David, Tafjord, Oyvind, Jha, Ananya Harsh, Soldaini, Luca, Smith, Noah A., Groeneveld, Dirk, Koh, Pang Wei, Dodge, Jesse, Hajishirzi, Hannaneh

We develop task scaling laws and model ladders to predict the individual task performance of pretrained language models (LMs) in the overtrained setting. Standard power laws for language modeling loss cannot accurately model task performance. Therefo

Magnetoelastic Interactions Reduce Hysteresis in Soft Magnets

Autor: Guan, Hongyi, Ahani, Negar, García-Cervera, Carlos J., Balakrishna, Ananya Renuka

The width of the magnetic hysteresis loop is often correlated with the material's magnetocrystalline anisotropy constant $\kappa_1$. Traditionally, a common approach to reduce the hysteresis width has been to develop alloys with $\kappa_1$ as close t
