-The general model was trained on a lot of particles with a variety of shapes and therefore learned a robust set of generic features. The last layers, however, learn a fairly abstract representation of the particles and it might be that they do not perfectly fit your particle at hand. In order to adapt this abstract representation within the network to your specific particle, fine-tuning only affects the last two convolutional layers, but keeps all others fixed.+The general model was trained on a lot of particles with a variety of shapes and therefore learned a robust set of generic features.

 The number of layers to fine tune (specified by layers_fine_tune in the //"Optional arguments"// tab) is still experimental. The default value of 2 worked for us but you might need more layers. The number of layers to fine tune (specified by layers_fine_tune in the //"Optional arguments"// tab) is still experimental.
