Exploding gradients are a problem where large error gradients accumulate and result in very large updates to neural network model weights during training. This has the effect of your model being unstable and unable to learn from your training data. In this post, you will discover the problem of exploding gradients with deep artificial neural networks.

An error gradient is the direction and magnitude calculated during the training of a neural network that is used to update the network weights in the right direction and by the right amount.
Data can change over time. This can result in poor and degrading predictive performance in predictive models that assume a static relationship between input and output variables. This problem of the changing underlying relationships in the data is called concept drift in the field of machine learning. In this post, you will discover the problem of concept drift and ways to you may be able to address it in your own predictive modeling problems.

TensorFlow is an open-source machine learning software built by Google to train neural networks. TensorFlow's neural networks are expressed in the form of stateful dataflow graphs. Each node in the graph represents the operations performed by neural networks on multi-dimensional arrays. These multi-dimensional arrays are commonly known as "tensors", hence the name TensorFlow. TensorFlow is a deep learning software system.
To compile this list, we explored deep learning MOOCs (Massive Open Online Courses) published by top universities, colleges, and leading tech companies. Dedicated to beginners, intermediate, and advanced learners, and covering most concepts of Deep Learning, from the most basic to the cutting-edge, all of these courses are free and self-paced, and some of them even offer certificates. It goes without saying that all of these courses come with some prerequisites: basic knowledge of mathematics, how to manipulate GitHub repositories, and a good command of programming languages like Python. Google has published an online course dedicated to deep learning via Udacity, the online course platform. Google's MOOC trains intermediate to advanced developers free of charge for 12 weeks on many aspects of deep learning, such as how to build and optimize deep neural networks.
The Keras Python deep learning library provides tools to visualize and better understand your neural network models. In this tutorial, you will discover exactly how to summarize and visualize your deep learning models in Keras. How to Visualize a Deep Learning Neural Network Model in Keras Photo by Ed Dunens, some rights reserved. We can start off by defining a simple multilayer Perceptron model in Keras that we can use as the subject for summarization and visualization. The model we will define has one input variable, a hidden layer with two neurons, and an output layer with one binary output.
The Python ecosystem with scikit-learn and pandas is required for operational machine learning. Python is the rising platform for professional machine learning because you can use the same code to explore different models in R&D then deploy it directly to production. In this mega Ebook written in the friendly Machine Learning Mastery style that you're used to, learn exactly how to get started and apply machine learning using the Python ecosystem. Click to jump straight to the packages. The recipes in this book alone are worth the money, but Jason very effectively breaks down the theory behind each algorithm, and outlines their appropriate use-case.

Are you familiar with Scikit-learn Pipelines? They are an extremely simple yet very useful tool for managing machine learning workflows. A typical machine learning task generally involves data preparation to varying degrees. We won't get into the wide array of activities which make up data preparation here, but there are many. Such tasks are known for taking up a large proportion of time spent on any given machine learning task.
