Effectively learning spatial indices

open access: yesProceedings of the VLDB Endowment, 2020
Machine learning, especially deep learning, is used increasingly to enable better solutions for data management tasks previously solved by other means, including database indexing. A recent study shows that a neural network can not only learn to predict the disk address of the data value associated with a one-dimensional search key but also outperform ...

Desirable Difficulties in Spatial Learning: Testing Enhances Subsequent Learning of Spatial Information [PDF]

open access: yesFrontiers in Psychology, 2018
Previous work has shown that testing can enhance learning and retention of subsequently studied new information. The present study investigated this forward testing effect in spatial memory. In two experiments, participants studied four successively presented 3 × 3 arrays, each composed of the same nine objects.

Environmental Enrichment Improved Learning and Memory, Increased Telencephalic Cell Proliferation, and Induced Differential Gene Expression in Colossoma macropomum

open access: yesFrontiers in Pharmacology, 2020
Fish use spatial cognition based on allocentric cues to navigate, but little is known about how environmental enrichment (EE) affects learning and memory in correlation with hematological changes or gene expression in the fish brain. Here we investigated

From Topological Analyses to Functional Modeling: The Case of Hippocampus

open access: yesFrontiers in Computational Neuroscience, 2021
Topological data analyses are widely used for describing and conceptualizing large volumes of neurobiological data, e.g., for quantifying spiking outputs of large neuronal ensembles and thus understanding the functions of the corresponding networks ...

Spatial models for context-aware indoor navigation systems: A survey [PDF]

open access: yes, 2012
This paper surveys indoor spatial models developed for research fields ranging from mobile robot mapping, to indoor location-based services (LBS), and most recently to context-aware navigation services applied to indoor environments.

Representational integration and differentiation in the human hippocampus following goal-directed navigation

open access: yeseLife, 2023
As we learn, dynamic memory processes build structured knowledge across our experiences. Such knowledge enables the formation of internal models of the world that we use to plan, make decisions, and act.

Recovery of Theta Frequency Oscillations in Rats Following Lateral Fluid Percussion Corresponds With a Mild Cognitive Phenotype

open access: yesFrontiers in Neurology, 2020
Whether from a fall, sports concussion, or even combat injury, there is a critical need to identify when an individual is able to return to play or work following traumatic brain injury (TBI).

The effect of landmark visualization in mobile maps on brain activity during navigation: A virtual reality study

open access: yesFrontiers in Virtual Reality, 2022
The frequent use of GPS-based navigation assistance is found to negatively affect spatial learning. Displaying landmarks effectively while providing wayfinding instructions on such services could facilitate spatial learning because landmarks help ...

Memantine and Riluzole Exacerbate, Rather Than Ameliorate Behavioral Deficits Induced by 8-OH-DPAT Sensitization in a Spatial Task

open access: yesBiomolecules, 2021
Chronic sensitization to serotonin 1A and 7 receptors agonist 8-OH-DPAT induces compulsive checking and perseverative behavior. As such, it has been used to model obsessive-compulsive disorder (OCD)-like behavior in mice and rats.

Fostering spatial ability development in and for authentic STEM learning [PDF]

open access: yes, 2023
Empirical interdisciplinary research has explored the role of spatial ability in STEM learning and achievement. While most of this research indicates that fostering spatial thinking in educational contexts has the potential to positively impact students’
