Query: LENAS: Learning-based Neural Architecture Search and Ensemble for 3D
  Radiotherapy Dose Prediction   Radiation therapy treatment planning is a complex process, as the target dose
prescription and normal tissue sparing are conflicting objectives. In order to
reduce human planning time efforts and improve the quality of treatment
planning, knowledge-based planning (KBP) is in high demand. In this study, we
propose a novel learning-based ensemble approach, named LENAS, which integrates
neural architecture search (NAS) with knowledge distillation for 3D
radiotherapy dose prediction. Specifically, the prediction network first
exhaustively searches each block from an enormous architecture space. Then,
multiple architectures with promising performance and a large diversity are
selected. To reduce the inference time, we adopt the teacher-student paradigm
by treating the combination of diverse outputs from multiple learned networks
as supervisions to guide the student network training. In addition, we apply
adversarial learning to optimize the student network to recover the knowledge
in teacher networks. To the best of our knowledge, this is the first attempt to
investigate NAS and knowledge distillation in ensemble learning, especially in
the field of medical image analysis. The proposed method has been evaluated on
two public datasets, i.e., the OpenKBP and AIMIS dataset. Extensive
experimental results demonstrate the effectiveness of our method and its
superior performance to the state-of-the-art methods. In addition, several
in-depth analysis and empirical guidelines are derived for ensemble learning.
