怎么翻译成中文

混合以及半参数模型在这个方向上很有希望。

Research challenges that remain include handling massive datasets and flexible modeling of high-dimentional data.Mixture and semiparametric models hold much promise in this direction.

根具上下文，Mixture and semiparametric models hold much promise in this direction 的意思是混合和半参数模型有希望能成功地处理庞大数据集与灵活地建模高维数据
