The knockoff method constructs a counterfeit variable for each original variable and requires the two to satisfy exchange symmetry in the joint distribution, thereby using the difference in statistics between original variables and knockoffs to control the FDR; column-permutation equivariance is a key prerequisite for constructing valid knockoff statistics.

UnverifiedAt runtime, NDD automatically resolves inter-column dependencies, schedules calls to user-defined model endpoints, and retries failed requests.61% similarUnverifiedAdjoint sensitivity analysis, by introducing adjoint variables, requires only one additional backward equation solve to simultaneously obtain gradient information of the objective function with respect to all parameters, offering significant computational advantages over forward sensitivity analysis in high-dimensional models.60% similarUnverified高质量harness通常采用混合检索策略，将语义相似度与符号精确匹配结合，再通过重排序模型对候选片段打分60% similarUnverifiedMean-field variational inference assumes that the posterior distribution can be decomposed into a product of mutually independent Gaussian distributions for each parameter, sacrificing the ability to capture correlations between parameters.58% similarUnverifiedAnyInit's approach is to automatically estimate the per-layer variance ratio for any layer through numerical or structural analysis and infer the initialization parameters in reverse, thereby bypassing dependence on closed-form formulas.58% similar
