How Memory in Optimization Algorithms Implicitly Modifies the Loss

arXiv:2502.02132v2 Announce Type: replace Abstract: In modern optimization methods used in deep learning, each update depends on the history of previous iterations, often referred to as memory, and this dependence decays fast as the iterates go further into the past.…

Higher-Order Causal Structure Learning with Additive Models

arXiv:2511.03831v1 Announce Type: new Abstract: Causal structure learning has long been the central task of inferring causal insights from data. Despite the abundance of real-world processes exhibiting higher-order mechanisms, however, an explicit treatment of interactions in causal discovery has received…

Enhancing Q-Value Updates in Deep Q-Learning via Successor-State Prediction

arXiv:2511.03836v1 Announce Type: new Abstract: Deep Q-Networks (DQNs) estimate future returns by learning from transitions sampled from a replay buffer. However, the target updates in DQN often rely on next states generated by actions from past, potentially suboptimal, policy. As…

Benchmark Datasets for Lead-Lag Forecasting on Social Platforms

arXiv:2511.03877v1 Announce Type: new Abstract: Social and collaborative platforms emit multivariate time-series traces in which early interactions-such as views, likes, or downloads-are followed, sometimes months or years later, by higher impact like citations, sales, or reviews. We formalize this setting…

Measure-Theoretic Time-Delay Embedding

arXiv:2409.08768v2 Announce Type: replace-cross Abstract: The celebrated Takens’ embedding theorem provides a theoretical foundation for reconstructing the full state of a dynamical system from partial observations. However, the classical theorem assumes that the underlying system is deterministic and that observations…

On Predicting Sociodemographics from Mobility Signals

arXiv:2511.03924v1 Announce Type: new Abstract: Inferring sociodemographic attributes from mobility data could help transportation planners better leverage passively collected datasets, but this task remains difficult due to weak and inconsistent relationships between mobility patterns and sociodemographic traits, as well as…
