Apr 24, 2018 · This is a tutorial of how to classify the Fashion-MNIST dataset with tf.keras, using a Convolutional Neural Network (CNN) architecture. In just a few lines of code, you can define and train a model that is able to classify the images with over 90% accuracy, even without much optimization. Dec 25, 2018 · Transfer Learning with Keras 25 Dec 2018. Transfer Learning is a very important concept in ML generally and DL specifically. It aims to reuse the knowledge gathered by an already trained model on a specific task and trasfer this knowledge to a new task. Dec 10, 2017 · Machine learning researchers would like to share outcomes. They might spend a lot of time to construct a neural networks structure, and train the model. It may last days or weeks to train a model. However, one can run the same model in seconds if he has the pre-constructed network structure and pre-trained weights. Keras is a library that makes it much easier for you to create these deep learning solutions. In a few lines of code, you can create a model that could require hundreds of lines of conventional code. This course, Deep Learning with Keras, will get you up to speed with both the theory and practice of using Keras to implement deep neural networks. Aug 08, 2017 · Luckily, Deep Learning supports an immensely useful feature called 'Transfer Learning'. Basically, you are able to take a pre-trained deep learning model - which is trained on a large-scale dataset such as ImageNet - and re-purpose it to handle an entirely different problem. Nov 11, 2017 · Use Keras Pretrained Models With Tensorflow. In my last post (the Simpsons Detector) I've used Keras as my deep-learning package to train and run CNN models.Since Keras is just an API on top of TensorFlow I wanted to play with the underlying layer and therefore implemented image-style-transfer with TF. We've just completed a whirlwind tour of Keras's core functionality, but we've only really scratched the surface. Hopefully you've gained the foundation to further explore all that Keras has to offer. For continued learning, we recommend studying other example models in Keras and Stanford's computer vision class.

Jun 01, 2017 · By using pre-trained models which have been previously trained on large datasets, we can directly use the weights and architecture obtained and apply the learning on our problem statement. This is known as transfer learning. We “transfer the learning” of the pre-trained model to our specific problem statement. Another way to overcome the problem of minimal training data is to use a pretrained model and augment it with a new training example. This approach is called transfer learning. Since TensorFlow and Keras provide a good mechanism for saving and loading models, this can be quite easily achieved, but out of scope here. Conclusion
