HierLoc: Hyperbolic Entity Embeddings for Hierarchical Visual Geolocation

ICLR 2026poster

Visual geolocalization, the task of predicting where an image was taken, remains challenging due to global scale, visual ambiguity, and the inherently hierarchical structure of geography. Existing paradigms rely on either large-scale retrieval, which requires storing a large number of image embeddin…

TurnBack: A Geospatial Route Cognition Benchmark for Large Language Models through Reverse Route

EMNLP 2025

Humans can interpret geospatial information through natural language, while the geospatial cognition capabilities of Large Language Models (LLMs) remain underexplored. Prior research in this domain has been constrained by non-quantifiable metrics, limited evaluation datasets; unclear research hierar

Box2Poly: Memory-Efficient Polygon Prediction of Arbitrarily Shaped and Rotated Text

AAAI 2024technical

Recently, Transformer-based text detection techniques have sought to predict polygons by encoding the coordinates of individual boundary vertices using distinct query features. However, this approach incurs a significant memory overhead and struggles to effectively capture the intricate relationship…
