The paper introduces a scalable approach to learning Determinantal Point Processes (DPPs) by modeling full‑rank interactions through a nonlinear kernel function and latent features. It proposes a surrogate function for maximum likelihood estimation and employs stochastic optimization with random features of the nonlinear kernel. Experiments on real‑world datasets show that this method improves the trade‑off between expressive power and computational scalability, achieving better generalization with fewer parameters.

The paper presents a variational learning framework that simultaneously infers non‑parametric interaction kernels and environmental or intra‑agent forces in collective dynamics. It extends existing methods to handle both interaction and environmental components, validating the approach on benchmark models such as synchronization, alignment, and attraction‑repulsion systems. A model‑selection procedure is also introduced to identify the best explanatory framework from trajectory data, enabling direct recovery of mechanistic interaction mechanisms.

CausalBind introduces a causal modeling framework for protein‑molecule virtual screening that focuses on sparse cross‑modality interactions rather than dense holistic alignment. By formalizing a V‑structure causal model with Heckman‑style selection, the authors prove that latent interaction concepts are identifiable only under sparsity constraints and propose three implementation variants. Experiments on DUD‑E and LIT‑PCBA benchmarks demonstrate that all variants outperform strong retrieval baselines, especially in early enrichment and out‑of‑distribution generalization.
