    "Welcome to our end-to-end example of the image classification algorithm training with image format. In this demo, we will use the Amazon SageMaker image classification algorithm in transfer learning mode to fine-tune a pre-trained model (trained on ImageNet data) to learn to classify a new dataset. In particular, the pre-trained model will be fine-tuned using the [Caltech-256 dataset](http://www.vision.caltech.edu/Image_Datasets/Caltech256/). \n",
