Futility stopping in clinical trials
Early stopping due to futility, also referred to as a go/nogo decision, during interim analysis has become an important feature of clinical trial designs. Current methods for futility stopping in literature are mostly based on conditional power or predictive power in conjunction with the theory of stochastic curtailment or group sequential design. They have certain drawbacks that have been note...
متن کاملEarly Stopping - But When?
Validation can be used to detect when overrtting starts during supervised training of a neural network; training is then stopped before convergence to avoid the overrtting (\early stopping"). The exact criterion used for validation-based early stopping, however, is usually chosen in an ad-hoc fashion or training is stopped interactively. This trick describes how to select a stopping criterion i...
متن کاملEarly stopping in L2Boosting
It is well known that the boosting-like algorithms, such as AdaBoost and many of its modifications, may over-fit the training data when the number of boosting iteration becomes large. Therefore, how to stop a boosting algorithm at an appropriate iteration time is a longstanding problem for the past decade (see Meir and Rastch (2003)). Bühlmann and Yu (2005) apply model selection criteria to est...
متن کاملSequential Testing for Early Stopping
Online evaluation methods, such as A/B and interleaving experiments, are widely used for search engine evaluation. Since they rely on noisy implicit user feedback, running each experiment takes a considerable time. Recently, the problem of reducing the duration of online experiments has received substantial attention from the research community. However, the possibility of using sequential stat...
متن کاملStopping trials early for commercial reasons: the risk-benefit relationship as a moral compass.
Decisions by industry sponsors to end clinical trials early for commercial reasons have been the subject of controversy. I argue that the principal consideration in assessing these decisions ought to be the way in which the termination would affect the trial's risk-benefit relationship. If there is not yet sufficient benefit to be gained from the study to offset the risks to which participants ...
