When Can You Correct Distribution Drift in Temporal Graph Generation? A Sharpening-Drift Tension and an Impossibility for Observation-Based Correction

It is proved that any corrector measurable with respect to past observations leaves at least the conditional variance of the statistic it tracks, and that trend extrapolation beats trusting the last observation only when $\mu^2>v(1-2\rho)$.

Dynamic Heterogeneous Graph Representation Learning: A Survey

This survey presents the first systematic review of DHG representation learning methods and proposes a novel algorithm-centric taxonomy that categorizes existing literature, including early embedding-based approaches, graph neural network (GNN)-based models, and relatively recent Transformer-based DHG methods, while explicitly highlighting their intrinsic modeling biases with respect to dynamic granularity.

What Tokens Truly Matter? The Logit Conflation Problem in LLM Sampling

This work identifies the Logit Conflation Problem, where a to-ken’s logit aggregates prompt-independent factors, including linguistic fluency and parametric associations, with prompt-relevance, and proposes SEAL-Sampling to isolate this component through attention-weighted attribution.
