Spatial representations of knowledge

Proceedings of the 4th annual international ACM SIGIR conference on Information storage and retrieval theoretical issues in information retrieval - SIGIR '81, 1981
This research examined the relationship between subjects' knowledge of an area and their similarity ratings of pairs of concepts. Knowledge was operationalized as (1) test score performance, and (2) correspondence with an expert's similarity judgments.

Spatial representation of soundscape

The Journal of the Acoustical Society of America, 2004
For the last 30 years the concept of soundscape has been largely adopted in many scientific disciplines and by the urban experts for the benefit of a better comprehension and management of the sound environment. However, the spatial representation of the soundscape as a simple tool for the description, management or composition of sound environment is ...

SpatialVLA: Exploring Spatial Representations for Visual-Language-Action Model

Robotics
In this paper, we claim that spatial understanding is the keypoint in robot manipulation, and propose SpatialVLA to explore effective spatial representations for the robot foundation model.

Interpreting and Editing Vision-Language Representations to Mitigate Hallucinations

International Conference on Learning Representations
We investigate the internal representations of vision-language models (VLMs) to address hallucinations, a persistent challenge despite advances in model size and training.

Learning Delicate Local Representations for Multi-Person Pose Estimation

European Conference on Computer Vision, 2020
In this paper, we propose a novel method called Residual Steps Network (RSN). RSN aggregates features with the same spatial size (Intra-level features) efficiently to obtain delicate local representations, which retain rich low-level spatial information ...

Part-Aligned Bilinear Representations for Person Re-identification

European Conference on Computer Vision, 2018
We propose a novel network that learns a part-aligned representation for person re-identification. It handles the body part misalignment problem, that is, body parts are misaligned across human detections due to pose/viewpoint change and unreliable ...

Mental representations of spatial relations

Cognitive Psychology, 1986
Abstract Three classes of theories of the mental representation of spatial relations were tested. Nonhierarchical theories propose that spatial relations among objects in an environment are mentally represented in networks or in imagelike, analog formats.

The Spatial Representation of Market Information

Marketing Science, 2001
To be used effectively, market knowledge and information must be structured and represented in ways that are parsimonious and conducive to efficient managerial decision making. This manuscript proposes a new latent structure spatial model for the representation of market information that meets this requirement.

State-Led Financial Regulation and Representations of Spatial Fixity: The Example of the Spanish Real Estate Sector

International Journal of Urban and Regional Research, 2018
This article offers a bottom‐up contribution to the fixity–motion literature. It aims to unravel the apparent contradiction of real estate spatial fixity in Spain, which is portrayed both as a barrier to accumulation and as a unique source of investment ...

A unified representation of spatial displacements

Mechanism and Machine Theory, 1984
Abstract The spatial screw displacement of a rigid body can be expressed in terms of points and in terms of lines by real (3 × 3)-matrices and (4 × 4)-matrices for the screw displacement of points, and by dual vectors and tensors, dual-number (3 × 3)-matrices, screw coordinates and dual-number quaternions for the screw displacement of lines.
