Complexity-Guided Component-wise Initialization for Language Model Pretraining

Pretrained language models often exhibit structured weight spectra, suggesting that training may repeatedly produce similar layerwise and component-wise organization. We ask whether these recurring spectral patterns can be reused as an initialization signal for GPT-2-style langua…

Gauging, Measuring, and Controlling Critic Complexity in Actor-Critic Reinforcement Learning

Konstantin Garbers

Actor-critic methods depend on learned critics, but critic quality is often evaluated only indirectly through return, temporal-difference error, or value loss. Critic complexity is introduced as an additional diagnostic and intervention dimension for actor-critic reinforcement le…
