Street View of the Cognitive Map

Street View of the Cognitive Map

To understand the origins of spatial navigational signals, Acharya et al. record the activity of hippocampal neurons in rats running in open two-dimensional environments in both the real world and in virtual reality. They find that a subset of hippocampal neurons have directional tuning that persists in virtual reality, where vestibular cues are absent.

Google Street View and Privacy

The Google Street View technology has proven to be highly controversial. Especially in a lot of European countries – where privacy and data protection laws are far stricter than e.g. in the United States – the launch of Street View has caused many residents and citizens to issues complaints to government officials about the project thereby claiming that it is a massive intrusion upon privacy an...

View{based Cognitive Map Learning by a N Autonomous Robot

This paper presents a view based approach to map learning and nav igation in mazes By means of graph theory we have shown that the view graph is a su cient representation for map behaviour such as path planning A neural network for unsupervised learning of the view graph from sequences of views is constructed We use a modi ed Kohonen learning rule that transforms temporal sequence rather than f...

Title: View{based Cognitive Map Learning by an Autonomous Robot

This paper presents a view{based approach to map learning and navigation in mazes. By means of graph theory we have shown that the view{graph is a suucient representation for map behaviour such as path planning. A neural network for unsupervised learning of the view{graph from sequences of views is constructed. We use a modiied Kohonen (1988) learning rule that transforms temporal sequence (rat...
