The Fibonacci numerology, in this approach, arises because the most important patterns involve the interaction of three such waves, and in the relevant states, the wave number for the third wave must be the sum of the other two wave numbers. The fundamental assumption of matched filtering is that the strain s(t) measured by the interferometric detector is made up of two additive components, namely the instrument noise n(t) and the (astrophysical) signal h(t): s(t)=n(t)+h(t) (1) Phys Rev Lett.

We present a detailed observational and theoretical study of an approximately three hour long X-ray burst (the "super burst ") observed by the Rossi X-ray Timing Explorer (RXTE) from the low mass X-ray binary (LMXB) 4U 1820-30. The Deep Filtering method takes the 1D strain directly as input and is able to correctly classify glitches as noise and detect true GW signals as well as simulated GW signals injected into these highly non-stationary non-Gaussian data streams, with similar sensitivity compared to matched-filtering.
