Data analysis and predictive systems and related methodologies

A method of optimising a model Mx suitable for use in data analysis and determining a prognostic outcome specific to a particular subject (input vector x), the subject comprising a number of variable features in relation to a scenario of interest for which there is a global dataset D of samples also having the same features relating to the scenario, and for which the outcome is known is disclosed. In one implementation, the method includes: (a) determining what number and a subset Vx of variable features will be used in assessing the outcome for the input vector x; (b) determining what number Kx of samples from within the global data set D will form a neighbourhood about x; (c) selecting suitable Kx samples from the global data set which have the variable features that most closely accord to the variable features of the particular subject x to form the neighbourhood Dx; (d) ranking the Vx variable features within the neighbourhood Dx in order of importance to the outcome of vector x and obtaining a weight vector Wx for all variable features Vx; (e) creating a prognostic model Mx, having a set of model parameters Px and the other parameters from (a)-(d); (f) testing the accuracy of the model Mx at e) for each sample from Dx; (g) storing both the accuracy from (f), and the model parameters developed in (a) to (e); (h) repeating (a) and/or (b) whilst applying an optimisation procedure to optimise Vx and/or Kx, to determine their optimal values, before repeating (c)-(h) until maximum accuracy at (f) is achieved.

Method and Device for Detecting a Fault of a Barometric Pressure Measuring System Arranged Aboard a Flying Device

The invention relates to a method and device for determining a fault of a barometric pressure measuring system arranged aboard a flying device. The method comprises the following steps: determining a current position POSGNSS(t) and an altitude zGNSS(t) of the flying device in a geodetic reference system at a point in time t using a satellite navigation system GNSS arranged aboard a flying device; determining a static pressure pAC(t) and/or a pressure level zAC(t) for the position POSGNSS(t) in provided weather analysis data ANDAT or in provided weather prognosis data PROGDAT of a numerical weather prediction model (NWP) using the pressure measuring system; determining a geopotential altitude ZAN/PROG(t) assigned to the static pressure pAC(t) for the position POSGNSS(t) in provided weather analysis data ANDAT or in provided weather prognosis data PROGDAT of a numerical weather prediction model (NWP); determining a static pressure pAN/PROG(t) assigned to the altitude zGNSS(t); determining the altitude deviation Δz(t)=zGNSS(t)−zAN/PROG(t) and/or determining the pressure deviation Δp(t)=pAC(t)−pAN/PROG(t); determining an altitude deviation Δz* averaged over a period of time Δt from Δz(t)=zGNSS(t)−zAN/PROG(t) and/or a pressure deviation Δp* averaged over a period of time Δt from Δp(t)=pAC(t)−pAN/PROG(t), wherein a fault of the pressure measuring system is deemed detected if the determined averaged altitude deviation |Δz*| is greater than or equal to a specified threshold G1, or if the averaged pressure deviation |Δp*| is greater than or equal to a specified threshold G2; and generating a warning signal if a fault is detected.
