<p>Please see the tutorial <a href="https://www.tensorflow.org/tutorials/image_retraining" rel="nofollow noreferrer">How to Retrain Inception's Final Layer for New Categories</a> on TensorFlow.</p>

<p>From the Tutorial:</p>

<blockquote>
  <p>Modern object recognition models have millions of parameters and can take weeks to fully train. Transfer learning is a technique that shortcuts a lot of this work by taking a fully-trained model for a set of categories like ImageNet, and retrains from the existing weights for new classes. In this example we'll be retraining the final layer from scratch, while leaving all the others untouched. For more information on the approach you can see <a href="http://arxiv.org/pdf/1310.1531v1.pdf" rel="nofollow noreferrer">this paper on Decaf</a>.</p>

Tensorflow classify image training
<p>Is there any way to add a new class to the existing 1000 classes of the inception v3 model in tensorflow..? or is it possible to fine tune the model by just adding more images to the existing category</p>
