On identification of the statistical dependency between inputs and outputs, an conditional density estimation is essential. The least-squares conditional density estimator (LS-CDE) proposed by Sugiyama et al. is more efficient and more applicable for more complex structures than regression models, which estimate the conditional mean of outputs. However, LS-CDE still suffers from large estimation error when many irrelevant features exist in inputs. In this paper, we propose extending LS-CDE to allow simultaneous feature selection during conditional density estimation and evaluate our proposed method by using numerical experiments. |
