For the second set, aiming at the multi-type noises problem, a DNN is trained with three types of noises, including Volvo, factory1 and f16 noises, and tested with m109 noise, destroyer engine noise, white noise and destroyer ops noise, whose results are showed in Table 4~7 respectively.
The authors had chosen different types of noise based on the extensive studies done by (Santamaria-Gomez et al., 2011; Amiri-Simkooei et al., 2008; Bos et al., 2008; Langbein, 2012; Williams, 2003) and shown that the most present types of noise in GPS time series analysis is: Power - law plus white noise, white noise only, a combination between white noise and random walk and a combination between white noise and flicker noise.
His topics include the pendulum with multiplicative noise, white and colored noise, the stability of an oscillator with random mass, a probabilistic approach to a deterministic pendulum, and whether order and chaos are contradictory.
