Experimental Setup

Neural Information Processing Systems

We provide an extended version of the Experimental Setup from Section 5 below. Linear Model This domain involves learning a linear model when the underlying mapping between features and predictions is cubic. Concretely, the aim is to choose the top B =1 out of N = 50 resources using a linear model. The fact that the features can be seen as 1-dimensional allows us to visualize the learned models (as seen in Figure 4). Predict: Given a feature xn U[0,1], use a linear model to predict the utility ห†yof choosing resource n, where the true utility is given by yn = 10x3n 6.5xn.



Flexible mapping of abstract domains by grid cells via self-supervised extraction and projection of generalized velocity signals

Neural Information Processing Systems

Grid cells in the medial entorhinal cortex create remarkable periodic maps of explored space during navigation. Recent studies show that they form similar maps of abstract cognitive spaces. Examples of such abstract environments include auditory tone sequences in which the pitch is continuously varied or images in which abstract features are continuously deformed (e.g., a cartoon bird whose legs stretch and shrink).
