- Abstract:
-
In order to solve the problem of lacking local fidelity and stability caused by local interpretable model-agnostic explanations (LIME) random perturbation sampling method, a new local interpretable model-agnostic explanation, IsomapVSG-LIME is proposed in this paper. In this method, isometric mapping virtual sample generation (IsomapVSG), a virtual sample generation method based on manifold learning, is used in substitution of random perturbation sampling method of LIME to generate samples, and aggregation hierarchical clustering method is used to select representative samples from virtual samples for training explanation model. In addition, this paper also proposes a new explanation stability evaluation index, the features sequence stability index (FSSI), which solves the problem that previous evaluation indexes ignore the sequential relationship of features and the flipping of explanations. Experimental results show that the proposed method outperforms the latest models in terms of stability and local fidelity.
