Identity Matters in Deep Learning
An emerging design principle in deep learning is that each layer of a deep artificial neural network should be able to easily express the identity transformation. This idea not only motivated various normalization techniques, such as \emph{batch normalization}, but was also key to the immense success of \emph{residual networks}. In this work, we put the principle of \emph{identity parameterization} on a more solid theoretical footing alongside further empirical progress. We first give a strikingly simple proof that arbitrarily deep linear residual networks have no spurious local optima. The same result for linear feed-forward networks in their standard parameterization is substantially more delicate. Second, we show that residual networks with ReLu activations have universal finite-sample expressivity in the sense that the network can represent any function of its sample provided that the model has more parameters than the sample size. Directly inspired by our theory, we experiment with a radically simple residual architecture consisting of only residual convolutional layers and ReLu activations, but no batch normalization, dropout, or max pool. Our model improves significantly on previous all-convolutional networks on the CIFAR10, CIFAR100, and ImageNet classification benchmarks.
Deep Learning Cheat Sheet
Deep Learning can be overwhelming when new to the subject. Here are some cheats and tips to get you through it. In this article we will go over common concepts found in Deep Learning to help get started on this amazing subject. The gradient is the partial derivative of a function that takes in multiple vectors and outputs a single value (i.e. The gradient tells us which direction to go on the graph to increase our output if we increase our variable input.
FinTech @CloudExpo #AI #ML #DL #FinTech #Blockchain #MachineLearning
Accordingly, attendees at the upcoming 20th Cloud Expo at the Javits Center in New York, June 6-8, 2017, will find fresh new content in a new track called FinTech, which will incorporate machine learning, artificial intelligence, deep learning, and blockchain into one track. Financial enterprises in New York City, London, Singapore, and other world financial capitals are embracing a new generation of smart, automated FinTech that eliminates many cumbersome, slow, and expensive intermediate processes from their businesses. FinTech brings efficiency as well as the ability to deliver new services and a much improved customer experience throughout the global financial services industry. FinTech is a natural fit with cloud computing, as new services are quickly developed, deployed, and scaled on public, private, and hybrid clouds. More than US$20 billion in venture capital is being invested in FinTech this year.

Apple to Start Publishing AI Research to Hasten Deep Learning
Apple hired Salakhutdinov from Carnegie Mellon University in October. The ban on publication has hindered the company's ability to hire the best talent because researchers are often less willing to work in a secretive environment where they can't engage openly with others. To compensate for the hiring difficulties, Apple has bought a series of AI startups, spending $200 million on Seattle-based Turi Inc. earlier this year to add to half a dozen other acquisitions.
The $1 Trillion Deep Learning Race for Smarter Cars - RTInsights
To learn to drive like a human, driverless cars will require massive amounts of data, programming, and computing power. According to a new report from KPMG, deep learning and other machine learning technologies could significantly change the automotive and transportation industries. By 2030, these advances could be worth $1 trillion. In the report, titled, "I see. To allow it to turn right after red? Except in New York where it is always illegal? Or where it is specifically forbidden? What if there is a pedestrian in the crossing? What if someone breaks the law and runs the red light in front of you? What if a bicycle comes speeding past you in the wrong direction?"
DeepMind's health-care app has some concerned about patient privacy
DeepMind, Google's artificial intelligence outfit, wants to streamline health care by using machine learning to provide medics with intelligent notifications. But not everyone is happy with the piles of data being shared with the company. The project will provide medics across a number of London hospitals with alerts about patients via an app called Streams. The app is meant to provide easy access to patient histories and test results for nurses and doctors. But its system will also learn to track patterns in patients' blood test data and flag cases that show early signs of kidney injury to the appropriate doctors.
AI, Machine Learning Data Give Chatbots Personality
Artificial intelligence has become a source of data for advertisers and their agency partners to identify consumer behavior. The idea is that machines can solve complex problems without having to be taught. Google's artificial intelligence company, DeepMind, and the AI collaboration group of companies like Microsoft and individuals such as Elon Musk, OpenAI, in separate announcements earlier this week said each would make their technology available to researchers and developers or anyone else wishing to use it. The independent moves by DeepMind and Open AI mark the beginning of a trend in the technology industry that will benefit advertising and media, as discussed at the MediaPost Search Insider Summit Friday in Deer Valley, Utah. During the panel on using artificial intelligence to support ecommerce and search, Jacob Loban, senior partner and managing director at MediaCom, said the company's been working with Microsoft to gain insights across applications and agents like Cortana and chatbots to gain insights about consumer behavior.
Deep learning saves lives
One of the most defining aspects of this century is the mass of data that is available everywhere. Using this data competently and analysing it is one of the many things that deep learning (DL) does. From fighting cancer by studying its pathology and patterns to warding off asteroid attacks, deep learning has put the world on a whole different trajectory. In deep learning the computer solves a problem independently by going through multiple levels of learning, which makes a lot of simple tasks much more efficient and accurate. This intricate level of computing requires GPU-accelerated computing to speed up tasks such as image, handwriting and voice identification.
