Orientation weighting restricts the direction of trajectories by predicted candidate trajectories and shrink ferret window , and reduces the amount of calculation . truncated sequential probability ratio test ( tsprt ) is also a algorithm of tbd , it can improve calculation efficiency by multistage thresholds to truncate tree - structured list of candidate trajectory of low degree of confidence 截斷序貫似然比方法也是一種tbd檢測的方法,其通過多級門限截斷置信度較低的軌跡樹達到提高效率的目的,在動態規劃中加入該算法,使之積累的軌跡數減少,降低了計算量和存儲量。
百科解釋
The sequential probability ratio test (SPRT) is a specific sequential hypothesis test, developed by Abraham Wald. Neyman and Pearson's 1933 result inspired Wald to reformulate it as a sequential analysis problem.
