Machine learning detects altered spatial navigation features in outdoor behaviour of Alzheimer's disease patients.
Scientific reports
Feb 24, 2022
Impairment of navigation is one of the earliest symptoms of Alzheimer's disease (AD), but to date studies have involved proxy tests of navigation rather than studies of real life behaviour. Here we use GPS tracking to measure ecological outdoor behav...
Exploring the spatial reasoning ability of neural models in human IQ tests.
Neural networks : the official journal of the International Neural Network Society
Mar 3, 2021
Although neural models have performed impressively well on various tasks such as image recognition and question answering, their reasoning ability has been measured in only few studies. In this work, we focus on spatial reasoning and explore the spat...
Biomimetic FPGA-based spatial navigation model with grid cells and place cells.
Neural networks : the official journal of the International Neural Network Society
Feb 13, 2021
The mammalian spatial navigation system is characterized by an initial divergence of internal representations, with disparate classes of neurons responding to distinct features including location, speed, borders and head direction; an ensuing converg...
A Robust Collision Perception Visual Neural Network With Specific Selectivity to Darker Objects.
IEEE transactions on cybernetics
Dec 3, 2020
Building an efficient and reliable collision perception visual system is a challenging problem for future robots and autonomous vehicles. The biological visual neural networks, which have evolved over millions of years in nature and are working perfe...
How automatic speed control based on distance affects user behaviours in telepresence robot navigation within dense conference-like environments.
PloS one
Nov 19, 2020
Telepresence robots allow users to be spatially and socially present in remote environments. Yet, it can be challenging to remotely operate telepresence robots, especially in dense environments such as academic conferences or workplaces. In this pape...
Introduction to part two of the special issue on computational models of hippocampus and related structures.
Hippocampus
Nov 13, 2020
Extensive computational modeling has focused on the hippocampal formation and related cortical structures. This introduction describes the topics addressed by individual articles in part two of this special issue of the journal Hippocampus on the top...
Deep Learning-Based Positioning of Visually Impaired People in Indoor Environments.
Sensors (Basel, Switzerland)
Oct 31, 2020
Wayfinding and navigation can present substantial challenges to visually impaired (VI) people. Some of the significant aspects of these challenges arise from the difficulty of knowing the location of a moving person with enough accuracy. Positioning ...
Fuzzy-based self organizing aggregation method for swarm robots.
Bio Systems
Jun 27, 2020
Fuzzy-based self-organizing aggregation method was suggested in the present study for swarm robots. In the suggested method, Swarm robots evaluate their limited sensor input via rules of fuzzy logic and display aggregation behavior with the suggested...
Bio-inspired multi-scale fusion.
Biological cybernetics
Apr 22, 2020
We reveal how implementing the homogeneous, multi-scale mapping frameworks observed in the mammalian brain's mapping systems radically improves the performance of a range of current robotic localization techniques. Roboticists have developed a range ...
From spatial navigation via visual construction to episodic memory and imagination.
Biological cybernetics
Apr 13, 2020
This hybrid of review and personal essay argues that models of visual construction are essential to extend spatial navigation models to models that link episodic memory and imagination. The starting point is the TAM-WG model, combining the Taxon Affo...
