We analyze multi-layer neural networks in the asymptotic regime of simultaneously (A) large network sizes and (B) large numbers of stochastic gradient descent training iterations. We rigorously establish the limiting behavior of the multilayer neural network output. The limit procedure is valid for any number of hidden layers and it naturally also describes the limiting behavior of the training loss. The ideas that we explore are to (a) sequentially take the limits of each hidden layer and (b) characterizing the evolution of parameters in terms of their initialization. The limit satisfies a system of integro-differential equations.

Skills in deep learning are in great demand, although these skills can be challenging to identify and to demonstrate. Explaining that you are familiar with a technique or type of problem is very different to being able to use it effectively with open source APIs on real datasets. Perhaps the most effective way of demonstrating skill as a deep learning practitioner is by developing models. A practitioner can practice on standard publicly available machine learning datasets and build up a portfolio of completed projects to both leverage on future projects and to demonstrate competence. In this post, you will discover how you can use small projects to demonstrate basic competence for using deep learning for predictive modeling.

We are happy to announce that Microsoft and Intel are partnering to bring optimized deep learning frameworks to Azure. These optimizations are available in a new offering on the Azure marketplace called the Intel Optimized Data Science VM for Linux (Ubuntu). Over the last few years, deep learning has become the state of the art for several machine learning and cognitive applications. Deep learning is a machine learning technique that leverages neural networks with multiple layers of non-linear transformations, so that the system can learn from data and build accurate models for a wide range of machine learning problems. Computer vision, language understanding, and speech recognition are all examples of deep learning at play today.

PyText is a deep-learning based NLP modeling framework built on PyTorch. PyText addresses the often-conflicting requirements of enabling rapid experimentation and of serving models at scale. It achieves this by providing simple and extensible interfaces and abstractions for model components, and by using PyTorch's capabilities of exporting models for inference via the optimized Caffe2 execution engine. We are using PyText in Facebook to iterate quickly on new modeling ideas and then seamlessly ship them at scale. To get started on a Cloud VM, check out our guide.

Neuroscience and artificial intelligence (AI) are two very different scientific disciplines. Neuroscience traces back to ancient civilizations, and AI is a decidedly modern phenomenon. At a cursory glance, it would seem that a branch of science of living systems would have little in common with one that springs from inanimate machines wholly created by humans. Yet discoveries in one field may result in breakthroughs in the other-- the two fields share a significant problem, and future opportunities. The origins of modern neuroscience is rooted in ancient human civilizations. One of the first descriptions of the brain's structure and neurosurgery can be traced back to 3000 - 2500 B.C. largely due to the efforts of the American Egyptologist Edwin Smith.

Deep Learning is a form of Artificial Intelligence, derived from Machine Learning. To understand what Deep Learning is, it is important to understand what Machine Learning is. In the 1950s, the British mathematician Alan Turing imagined a machine capable of learning, a "Learning Machine". Over the next few decades, different Machine Learning techniques were developed to create algorithms that could learn and improve independently. These techniques include artificial neural networks.

We depart from the traditional approaches which rely on explicit mapping and exploration (like a cartographer who tries to localise themselves and draw a map at the same time). Our approach, in contrast, is to learn to navigate as humans used to do, without maps, GPS localisation, or other aids, using only visual observations. We build a neural network agent that inputs images observed from the environment and predicts the next action it should take in that environment. We train it end-to-end using deep reinforcement learning, similarly to some recent work on learning to navigate in complex 3D mazes and reinforcement learning with unsupervised auxiliary tasks for playing games. Unlike those studies, which were conducted on small-scale simulated maze environments, we utilise city-scale real-world data, including complex intersections, footpaths, tunnels, and diverse topology across London, Paris, and New York City.

I'm going to tell a story: one you've almost certainly heard before, but with a different emphasis than you're used to. To a first (order) approximation, all modern deep learning models are trained using gradient descent. At each step of gradient descent, your parameter values begin at some starting point, and you move them in the direction of greatest loss reduction. You do this by taking the derivative of your loss with respect to your whole vector of parameters, otherwise called the Jacobian. However, this is just the first derivative of your loss, and it doesn't tell you anything about curvature, or, how quickly your first derivative is changing.
