Transfer Learning Alexnet. Transfer learning using alexnet load data. Unzip and load the new images as an image datastore.

The alexnet employing the transfer learning which uses weights of the pre trained network on imagenet dataset has shown exceptional performance. Here we will freeze the weights for all of the network except that of the final fully connected layer. Alexnet has learned hierarchical abstract features such as edges shapes corners intensities and objects from the 2d imagenet dataset.
Transfer learning is called fine tuning a pre trained cnn to perform classification on a new collection of images.
But in this article we will not use the pre trained weights and simply define the cnn according to the proposed architecture. Transfer learning consists of taking features learned on one problem and leveraging them on a new similar problem. Some of those features can be shared between natural images and neuroimages 29 and thus enable knowledge transfer between them without requiring domain knowledge.
