evolution each cognitive sensor starts construction of its separate model of space and time from the set of observations. This model includes the set S of states and the set R of transitions between these states. The set of states describes static features of observable world, while the set of transitions describes its dynamic features. Fig. 1 illustrates measurements performed by sensor 5 during time range which includes four different types of impact on the object: creep, static, dynamic and repair. During analysis of data processing by CS-DANN architecture we used several quantities. This set includes total number of perceptive neurons, total number of neurons of preprocessing layer, total number of connections between neurons of preprocessing layer, and value of prediction RMSE.

Fig. 1. Tilt values measured by sensor 5 in the range between 260000 and 270000 measurements.

Fig. 2. Total number of transitions between states measured for subnet of CS 5 in the range between 260000 and 270000 measurements of tilt.
