Kernel Reboot: Breaking the Boundaries of Neural Tangent Kernels for Neural Fields

The paper introduces three algorithms—NTK-KIP, MetaQuill, and MetaQuill-KIP—to enhance neural fields (NFs) for reconstructing signals from sparse data. NTK-KIP distills a support set of coordinates to enable non‑linear inpainting with a finite NTK, while MetaQuill meta‑learns a shared initialization that allows quick adaptation to new scenes via a small weight offset. MetaQuill-KIP combines both approaches, achieving high‑quality, semantically plausible reconstructions with lightweight per‑instance adaptation, outperforming diffusion‑style baselines that rely on large pretrained generative models.

DeCo: Efficient Decouple-to-Couple Learning for Multi-Task Visual Grounding

DeCo introduces an efficient decouple-to-couple learning framework for multi-task visual grounding, addressing conflicts between localization and segmentation tasks. It first applies Task-aware Semantic Decoupling (TSD) to separate shared visual cues into task-specific features guided by salient words, then uses Hybrid Prior Coupling (HPC) to merge sentence-level semantic priors with mask-derived spatial priors for improved grounding. Experiments across multiple natural and remote sensing datasets show that DeCo achieves state‑of‑the‑art performance while requiring only lightweight trainable parameters on a frozen multimodal encoder.

FLEET: Token-Based Feature Extraction for Event Camera-based Reinforcement Learning

FLEET is a token‑based feature extractor that processes event camera data directly, using random Fourier features and cross‑attention to compress variable‑length event streams into fixed‑size latent representations. By decoupling inference cost from sensor resolution, it avoids the high compute and temporal blurring associated with CNN‑based grid aggregation. Experiments on a new high‑throughput benchmark show that FLEET outperforms state‑of‑the‑art methods and remains robust across different observation frequencies.

MIND the Gap: A Geographic Implicit Neural Representation with Adjustable Spatial Scale

The paper introduces MIND, a method that distills specialist geospatial model embeddings into a single generalist coordinate embedding with adjustable spatial granularity, using nested supervision across multiple embedding dimensions. MIND’s design allows downstream predictors to use only leading chunks or apply a Chunked Penalty to downweight finer details without retraining the INR. The authors evaluate MIND on CoordBench, a large INR benchmark of 52 datasets and 78 targets, and report that MIND and its Chunked Penalty variant achieve the highest regression and classification scores, especially under regional holdout, establishing a new state‑of‑the‑art for geographic implicit neural representations.

GeoChrono: Benchmarking and Rethinking Long-Term Temporal Understanding in Remote Sensing

arXiv:2607. 15768v1 Announce Type: cross Abstract: Remote sensing offers an unparalleled vantage point for observing the Earth's long-term surface evolution, yet it demands that a model not only perceive land cover at isolated moments, but also track changes, memorize evolution histories, and reason across time and space.
