Deep learning models can take hours, days or even weeks to train. If the run is stopped unexpectedly, you can lose a lot of work. In this post you will discover how you can check-point your deep learning models during training in Python using the Keras library. Let’s get started. Jun/2016: First published Update Mar/2017: […]
Hyperparameter optimization is a big part of deep learning. The reason is that neural networks are notoriously difficult to configure and there are a lot of parameters that need to be set. On top of that, individual models can be very slow to train. In this post you will discover how you can use the grid […]
If you’ve looked at Keras models on Github, you’ve probably noticed that there are some different ways to create models in Keras. There’s the Sequential model which allows you to define an entire model in a single line, usually with some line breaks for readability, then there’s the functional interface that allows for more complicated […]
Keras is an easy to use and powerful Python library for deep learning. There are a lot of decisions to make when designing and configuring your deep learning models. Most of these decisions must be resolved empirically through trial and error and evaluating them on real data. As such, it is critically important to have […]
We usually use TensorFlow to build a neural network. However, TensorFlow is not limited to this. Behind the scene, TensorFlow is a tensor library with automatic differentiation capability. Hence we can easily use it to solve a numerical optimization problem with gradient descent. In this post, we are going to show how TensorFlow’s automatic differentiation […]
Machine learning is a broad topic. Deep learning, in particular, is a way of using neural networks for machine learning. Neural network is probably a concept older than machine learning, dated back to 1950s. Unsurprisingly, there were many libraries created for it. In the following, we will give an overview of some of the famous […]
The Keras Python library for deep learning focuses on the creation of models as a sequence of layers. In this post you will discover the simple components that you can use to create neural networks and simple deep learning models using Keras from TensorFlow. Let’s get started. May 2016: First version Update Mar/2017: Updated example […]
Keras is a simple and powerful Python library for deep learning. Given that deep learning models can take hours, days and even weeks to train, it is important to know how to save and load them from disk. In this post, you will discover how you can save your Keras models to file and load them […]
Keras is a powerful and easy-to-use free open source Python library for developing and evaluating deep learning models. It is part of the TensorFlow library and allows you to define and train neural network models in just a few lines of code. In this tutorial, you will discover how to create your first deep learning neural […]
You’ve probably been told to standardize or normalize inputs to your model to improve performance. But what is normalization and how can we implement it easily in our deep learning models to improve performance? Normalizing our inputs aims to create a set of features that are on the same scale as each other, which we’ll […]
