Spatio temporal continuity.

The spatio-temporal continuity thesis: that a thing A is the same as the thing B if A and B are connected by a continuous path through space-time. What does temporal discontinuity mean? Temporal discontinuities are temporal positions marking a sudden breakage of projective identity. Again, such losses of projective identity take place every ...An improved TP NN Queries method is proposed that searches the TPR-TREE once to get the curve of distance changes between the query object and the candidate nearest neighbor set, and then the NN set and makes a practical improvement.

Throughout this text, an arbitrary poset T may be interpreted as a spatio-temporal scale.This means that for every element \(u,v \in T\), we say that u lies before v, or v lays after u, when \(u \le v\), and that u lays beside v when u and v are incomparable. In other words, there is the time dimension that increases with the order, and, there is the space dimension where incomparable elements ...

In addition, we exploit the attention layer in the spatial and temporal modules to simultaneously emphasize multiple important features. Experimental results …Jan 22, 2009 · This suggestion might seem to be an answer to Wiggins's criticism of the notion of identity as spatio-temporal continuity, except that Bostock intends his definition for matter rather than substance, and does not mind, it seems, if the notion of 'matter' is understood in a collective sense (as the matter of all things in the limited cosmos ...

Because MME only captures the co-occurrence relationship among location, time and keywords, but ignores the vicinity correlation of spatio-temporal continuity, resulting in the embedding results of adjacent time and location less compactly.Human movements are dynamic and continuous in nature. However, how the spatiotemporal continuity influences working memory for movements is still unclear.on spatio-temporal information conveyed by the hippocampal formation. More specifically, state-of-the-art research points to the crucial role of the hippocampus in generating and storing sequences of spatio-temporal continuity (e.g. Burgess, Maguire, & O'Keefe, 2002; Buzsáki & Moser, 2013), which are the basic pre-requisites of all spatial
