How do we get rid of the "Documentation assistant" icon at the lower right web browser corner when viewing esri's online documentaion?

Neural state space alignment for magnitude generalization in humans and recurrent networks  Reference: Hannah Sheahan, Fabrice Luyckx, Stephanie Nelli, Clemens Teupe, Christopher Summerfield, Neural state space alignment for magnitude generalization in humans and recurrent networks, Neuron, Volume 109, Issue 7, 2021, Pages 1214-1226.e8, ISSN 0896-6273, https://doi.org/10.1016/j.neuron.2021.02.004. (https://www.sciencedirect.com/science/article/pii/S0896627321000787) Abstract: Summary A prerequisite for intelligent behavior is to understand how stimuli are related and to generalize this knowledge across contexts. Generalization can be challenging when relational patterns are shared across contexts but exist on different physical scales. Here, we studied neural representations in humans and recurrent neural networks performing a magnitude comparison task, for which it was advantageous to generalize concepts of “more” or “less” between contexts. Using multivariate analysis of human brain signals and of neural network hidden unit activity, we observed that both systems developed parallel neural “number lines” for each context. In both model systems, these number state spaces were aligned in a way that explicitly facilitated generalization of relational concepts (more and less). These findings suggest a previously overlooked role for neural normalization in supporting transfer of a simple form of abstract relational knowledge (magnitude) in humans and machine learning systems.
