Information as Structural Alignment: A Dynamical Theory of Continual Learning

Researchers introduce the Informational Buildup Framework (IBF), a new approach to continual learning that eliminates catastrophic forgetting by treating information as structural alignment rather than stored parameters. The framework demonstrates superior performance across multiple domains including chess and image classification, achieving near-zero forgetting without requiring raw data replay.

It's Not a Lottery, It's a Race: Understanding How Gradient Descent Adapts the Network's Capacity to the Task

Researchers have identified three fundamental dynamical principles—mutual alignment, unlocking, and racing—that explain how gradient descent training reduces neural network capacity to match task requirements. This theoretical advancement clarifies the mechanisms behind the lottery ticket hypothesis and why certain initial neuron conditions lead to higher weight norms, bridging a significant gap between empirical neural network success and theoretical understanding.

StructRL: Recovering Dynamic Programming Structure from Learning Dynamics in Distributional Reinforcement Learning

StructRL is a new reinforcement learning framework that recovers dynamic programming structure from distributional learning dynamics without requiring explicit models. The research demonstrates that temporal patterns in return distribution evolution reveal inherent structure in how information propagates through state spaces, enabling more efficient and stable learning.

Scaling of learning time for high dimensional inputs

Researchers present theoretical analysis showing that neural network learning times scale supralinearly with input dimensionality, creating fundamental limitations for high-dimensional learning. The study uses Hebbian learning models to demonstrate that higher input dimensions result in smaller gradients and prohibitively long learning times.
