Fig. 3From: Application of dose-volume histogram prediction in biologically related models for nasopharyngeal carcinomas treatment planningFlow chart of the GRU-RNN. RNN-GRU consists of 3 GRUs with the sizes of hidden states were 18, 9 and 1, respectively. Dv mean the volume proportion with deposition not greater than D was v and \( {D}_v^{\prime } \) was the predictive value. In the practical, Δv was set to 0.1%Back to article page
