We all know about the image classification problem. Given an image can you find out the class the image belongs to? We can solve any new image classification problem with ConvNets and Transfer Learning using pre-trained nets. ConvNet as fixed feature extractor. Take a ConvNet pretrained on ImageNet, remove the last fully-connected layer (this layer’s outputs are the 1000 class scores for a different task like ImageNet), then treat the rest of the ConvNet as a fixed feature extractor for the new dataset.
