It is offered to speed up convergence by increasing learning rate on flat surfaces and decreasing the learning rate when the slope increases in the error valley. Different ways are introduced for varying the learning rate [25]. The following describes the procedure used in this study: The trajectory of error function without momentum The trajectory of error function with momentum Stable point Fig. 3. H. Vahidnia et al. i. If the squared error, over the entire training set, increases by more than some set percentage ξ (typically 1 to 4%) after a weight update, then the weight update is discarded, the learning rate η is multiplied by some factor 0<ρ<1, and the momentum coefficient α (if it is used) is set to zero.

The sizes of the grid tiles depend on the density of sensors as well as the repetition and frequency of the events of interest. We propose to assign sensitivity levels to every tile. A sensitivity level concerns a specific event and follows from the sensitivities of the spatial objects located in the tile where this event happened. Using a thorough examination of the tiles’ sensitivities, our model allows for the prioritization of sensing activities. Every detected event has a set of effects that may be triggered instantaneously or as a reaction chain.
