4 results about "Ratio value" patented technology

Techniques are provided for analyzing multiple filters in a solution domain to identify filter instability. A processor may compute, for each filter, a residual value for each of one or more update types utilizing misclosure values that correspond to the update type and are from a rolling history. The processor may compute a ratio value from the residual values computed for the same update type and across two different filters. The ratio value may indicate which filter is experiencing a larger magnitude of difference between two solutions utilized to generate a combined solution. The processor may compare the ratio value, over a time period, with one or more threshold values to identify at least one unstable filter. In response, the processor may take one or more actions, e.g., using the solution from a stable filter instead of the unstable filter, re-initializing the unstable filter using the stable filter, etc.
