Transferring parameters of convolutional neural network (CNN). First, network is trained on source task (ImageNet classification, top row) with large amount of available labeled images. Then, convolutional layers (C1-C5) are transferred to target task(brain tumour and encephalitis classification, bottom row). We remove original fully connected layers (FC6-FC8) and add adaptation layer (FCa-FCc). Last, we fine-tune new model on labeled data of target task.
