Heterogeneous Knowledge Distillation using Information Flow Modeling

1 code implementation CVPR 2020 Nikolaos Passalis, Maria Tzelepi, Anastasios Tefas

The proposed method is capable of overcoming the aforementioned limitations by using an appropriate supervision scheme during the different phases of the training process, as well as by designing and training an appropriate auxiliary teacher model that acts as a proxy model capable of "explaining" the way the teacher works to the student.
