Each day billions of photographs are uploaded to photo-sharing services and social media platforms, and Cornell computer science researchers are figuring out ways to analyze this visual treasure trove through deep-learning methods. Kavita Bala, professor of computer science; Noah Snavely, associate professor computer science at Cornell Tech; and Kevin Matzen, M.S. '15, Ph.D. '16, have released their results in a new paper, "StreetStyle: Exploring world-wide clothing styles from millions of photos." "We present a framework for visual discovery at scale, analyzing clothing and fashion across millions of images of people around the world and spanning several years," Snavely said. Bala said the group used deep learning to detect various attributes – the color or sleeve length of shirts, whether a person is wearing glasses or a hat, and so on – in millions of images. "Using these detected attributes, we can then derive visual insight," Bala said.

That's when an emoji steps in to fill the void and save the day. Whether you like it or not, emoji aren't going anywhere -- in fact, they've quickly become an alternate way to express an array of emotions. As a result, researchers at MIT's media lab have created DeepMoji, a Twitter-based deep learning algorithm that uses 1.2 billion tweets with emoji to predict the emotion being conveyed by the user via emoji. The researchers believe the more data the model can accumulate, the bigger the possibility of companies or chatbots using the algorithm. DeepMoji uses deep learning, a subset of machine learning that trains an algorithm to learn and decipher patterns by feeding it huge amounts of data.

This post is inspired by material studied while interning with @jeremyphoward and @math_rachel's fast.ai, in particular Lesson 14 of their course Cutting Edge Deep Learning for Coders, taught at USF's Data Institute. If you'd like to see my end-to-end code for this project, please check out my repository There's Waldo. By now, everyone outside of the field likely knows that recent reports of the "Facebook AI Incident" have been greatly exaggerated (Fake News!). That's an understatement; the reported story is a gross distortion of an otherwise exciting research paper at the hands of horrendous journalists. No, Skynet has not gained awareness.

Y Combinator backed Plasticity is tackling the problem of getting software systems to better understand text, using deep learning models trained to understand what they're reading on Wikipedia articles -- and offering an API for developers to enhance their own interfaces. Specifically they're offering two APIs for developers to build "more robust conversational interfaces", as they put it -- with the aim of becoming a "centralized solution" for Natural Language Processing (NLP). Their APIs are due to be switched from private to public beta on Monday. "One thing where we think this is really useful for is conversational interfaces where you want to integrate real world knowledge," says co-founder Alex Sands. "We think it's also really useful when you want to provide instant answers in your application -- whether that's over the entire Internet or over a custom corpus."

The following problems appeared in the assignments in the Udacity course Deep Learning (by Google). The descriptions of the problems are taken from the assignments (continued from the last post). Let's try to get the best performance using a multi-layer model! The following figure recapitulates the neural network with a 3 hidden layers, the first one with 2048 nodes, the second one with 512 nodes and the third one with with 128nodes, each one with Relu intermediate outputs. The L2 regularizations applied on the lossfunction for the weights learnt at the input and the hidden layers are λ1, λ2, λ3 and λ4, respectively.

This week, the Interactive Advertising Bureau (IAB) launched a working group focusing on artificial intelligence and machine learning in response to "significant member interest." Make no mistake, AI is quickly coming off the pages of science fiction and being implemented across the marketing, media, and advertising industries. So, what is AI and how exactly can brands make the best use of it? Artificial Intelligence (AI) is an umbrella term for a large number of technologies that can train software to think and learn on its own. That might sound rather lofty, but if you look around in the digital world, low-level AI is already being deployed in things from simple spam filters to the recommendation engines on ecommerce sites.

The course is a new one by Andrew Ng, Co-founder, Coursera; Adjunct Professor, Stanford University; formerly head of Baidu AI Group/Google Brain. It will start Aug 15. About this course: If you want to break into cutting-edge AI, this course will help you do so. Deep learning engineers are highly sought after, and mastering deep learning will give you numerous new career opportunities. Deep learning is also a new "superpower" that will let you build AI systems that just weren't possible a few years ago.

Last year, Google's DeepMind announced a partnership with Blizzard Entertainment to develop and test artificial intelligence (AI) agents in the popular real-time strategy game StarCraft II. Now, DeepMind has released a series of tools they're calling StarCraft II Learning Environment (SC2LE) to test their agents against human competitors, as well as enable researchers to develop their own agents for the game. "Testing our agents in games that are not specifically designed for AI research, and where humans play well, is crucial to benchmark agent performance," DeepMind's team wrote in a blog post. The large pool of online StarCraft II players will provide a huge variety of "extremely talented opponents" from which the AI can learn. Details of DeepMind's research were published in a paper alongside the released toolset, which includes a machine learning API; a dataset of game replays; an open source version of PySC2, the Python component SC2LE; and more.

AI and Deep Learning are transforming the way we understand software, making computers more intelligent than we could even imagine just a decade ago. Deep Learning algorithms are being used across a broad range of industries – as the fundamental driver of AI, being able to tackle Deep Learning is going to a vital and valuable skill not only within the tech world but also for the wider global economy that depends upon knowledge and insight for growth and success. It's something that's moving beyond the realm of data science – if you're a Java developer, this book gives you a great opportunity to expand your skillset. Starting with an introduction to basic machine learning algorithms, to give you a solid foundation, Deep Learning with Java takes you further into this vital world of stunning predictive insights and remarkable machine intelligence. Once you've got to grips with the fundamental mathematical principles, you'll start exploring neural networks and identify how to tackle challenges in large networks using advanced algorithms.

One of the big topics that's being discussed at length for the last couple of years is artificial intelligence (AI). Machine learning is emerging as the field within AI that's seeing the most amounts of real-world applications and use cases. AI will impact almost every aspect over the next two decades and infotech is no exception. Take, for example, a historic event that unfolded in March 2016 demonstrated the power of machine learning: the victory of the program AlphaGo over professional gamer Lee Sedol in the Google DeepMind Challenge. This exciting technological breakthrough demonstrates how far AI has come, and how it's now able to catch humans out.
