…a good lesson for Data Scientists is to question their assumptions and to be especially skeptical when predicting a rare event with limited history using human behavior.
Machine Learning and AI Market Landscape, 2016
For the first time, a “one stop shop” of the machine intelligence stack is coming into view—even if it’s a year or two off from being neatly formalized. The maturing of that stack might explain why more established companies are more focused on building legitimate machine intelligence capabilities. Anyone who has their wits about them is still going to be making initial build-and-buy decisions, so we figured an early attempt at laying out these technologies is better than no attempt.
If this year’s landscape shows anything, it’s that the impact of machine intelligence is already here. Almost every industry is already being affected, from agriculture to transportation. Every employee can use machine intelligence to become more productive with tools that exist today. Companies have at their disposal, for the first time, the full set of building blocks to begin embedding machine intelligence in their businesses.
And unlike with the internet, where latecomers often bested those who were first to market, the companies that get started immediately with machine intelligence could enjoy a lasting advantage.
Country Ranking of IoT Preparedness
IDC:
[This is an] updated index ranking the Group of 20 (G20) nations on their preparedness for Internet of Things (IoT) development. The original index was first published in 2013 but this updated index is now comprised of 13 criteria that IDC views as necessary for sustained development of the IoT and reflects each nation’s economic stature, technological preparedness, and business readiness to benefit from the efficiencies linked to IoT solutions.
The United States, South Korea, and the United Kingdom ranked as the three countries most ready to generate and benefit from the IoT. The U.S. scored particularly well on measures such as ease of doing business, government effectiveness, innovation, and cloud infrastructure, as well as GDP and technology spending as a percent of GDP. South Korea, despite a modest GDP, scored extremely well on IoT-specific spending and has a business environment that fosters innovation and promotes attractive investment opportunities. Similarly, the U.K. scored very highly on measures of ease of doing business, government effectiveness, regulatory quality, start-up procedures, innovation, and broadband penetration.
The standout country in the ranking proved to be Australia, which, despite its relatively small GDP, scored exceptionally high on ease of doing business and start-up procedures, government effectiveness and regulatory quality, and innovation and education. Australia’s scores point to a country that has the necessary ingredients for a business environment that is ready for the growth of IoT.
Mobile advertising now accounts for nearly half of online ad budgets
Spending on mobile advertising in the US soared 89 per cent to $15.5bn in the first half of the year, taking up nearly half of online ad budgets, new data show. Mobile makes up 47 per cent of all online ad expenditures — up from 30 per cent a year ago and far surpassing the 19 per cent share taken by banner ads, according to a report from the Interactive Advertising Bureau and PwC, the professional services firm.

DeepBench from Baidu: Benchmarking Hardware for Deep Learning

At the O’Reilly Artificial Intelligence conference, Baidu Research announced DeepBench, an open source benchmarking tool for evaluating the performance of deep learning operations on different hardware platforms. Greg Diamos and Sharan Narang of Baidu Research’s Silicon Valley AI Lab talked at the conference about the motivation for developing the benchmark and why faster computers are crucial to the continued success of deep learning.
The harbinger of the current AI Spring, deep learning is a machine learning method using “artificial neural networks,” moving vast amounts of data through many layers of hardware and software, each layer coming up with its own representation of the data and passing what it “learned” to the next layer. As a widely publicized deep learning project has demonstrated four years ago, feeding such an artificial neural network with images extracted from 10 million videos can result in the computer (in this case, an array of 16,000 processors) learning to identify and label correctly an image of a cat. One of the leaders of that “Google Brain” project was Andrew Ng, who is today the Chief Scientist at Baidu and the head of Baidu Research.
Research areas of interest to by Baidu Research include image recognition, speech recognition, natural language processing, robotics, and big data. Its Silicon Valley AI Lab has deep learning and systems research teams that work together “to explore the latest in deep learning algorithms as well as find innovative ways to accelerate AI research with new hardware and software technologies.”
DeepBench is an attempt to accelerate the development of the hardware foundation for deep learning, by helping hardware developers optimize their processors for deep learning applications, and specifically, for the “training” phase in which the system learns through trial and error. “There are many different types of applications in deep learning—if you are a hardware manufacturer, you may not understand how to build for them. We are providing a tool for people to help them see if a change to a processor [design] improves performance and how it affects the application,” says Diamos. One of the exciting things about deep learning for him (and no doubt for many other researchers) is that “as the computer gets faster, the application gets better and the algorithms get smarter.”
Case in point is speech recognition. Or more specifically, DeepSpeech, Baidu Research’s “state-of-the-art speech recognition system developed using end-to-end deep learning.” The most important aspect of this system is its simplicity, says Diamos, with audio on one end, text on the other end, and a single learning algorithm (a recurring convolutional neural network), sitting in the middle. “We can take exactly the same architecture and apply it to both English and Mandarin with greater accuracy than systems we were building in the past,” says Diamos.
In Mandarin, the system is more accurate in transcribing audio to text than native speakers, as the latter may have difficulty understanding what is said because of noise level or accent. Indeed, the data set used by DeepSpeech is very large because it was created by mixing hours of synthetic noise with the raw audio, explains Narang. The largest publicly available data set is about 2000 hours of audio recordings while the one used by DeepSpeech clocks in at 100,000 hours or 10 terabytes of data.
The approach taken by the developers of DeepSpeech is superior to other approaches argue Narang and Diamos. Traditional speech recognition systems using a “hand-designed algorithm,” get more accurate with more data but eventually saturate, requiring a domain expert to develop a new algorithm. The hybrid approach adds a deep convolutional neural network. The result is better scaling but again the performance eventually saturates. DeepSpeech uses deep learning as the entire algorithm and achieves continuous improvement in performance (accuracy) with larger data sets and larger models (more and bigger layers).
Bigger is better. But to capitalize on this feature (pun intended) of deep learning, you need faster computers. “The biggest bottleneck,” says Narang, “is training the model.” He concludes: “Large data sets, a complex model with many layers, and the need to train the model many times is slowing down deep learning research. To make rapid progress, we need to reduce model training time. That’s why we need tools to benchmark the performance of deep learning training. DeepBench allows us to measure the time it takes to perform the underlying deep learning operation. It establishes a line in the sand that will encourage hardware developers to do better by focusing on the right issues.”

Maana Deploys AI to Optimize Enterprise Knowledge at Maersk
Maana Knowledge Platform for Oil and Gas
Does your company suffer from corporate amnesia? Palo Alto, California-based startup Maana has developed a cure for what ails organizations everywhere: Knowledge of how to perform a certain task or make a specific decision walks out the door with employees migrating to another job or retiring. Even when this tacit knowledge is captured, codified and stored in a database, it may not be accessible to the people who need it, when they need it. “We patented a unique and novel way of indexing and organizing the knowledge that is locked in data silos across the organization,” says founder and CEO Babur Ozden. Today, Maana released a new version of its AI-driven platform.
Failing organizational memory is particularly harmful when there is a “decision deadline,” explains Ozden: “These are decisions that need to take place along the workflow of an operation and need to be taken in a few hours or a few minutes.” Maana’s knowledge graph, which captures complex relations between actions, processes, and assets, coupled with advanced AI algorithms, semantic search, and deep learning, helps employees make faster and more relevant data-driven decisions by providing them with the relevant pieces of organizational memory at the moment they need it most.
Maana’s technology “captures the knowledge people acquire on the job and enables other employees, who do not have a similar experience, to have a head start in making a decision instead of starting from zero,” says Ibrahim Gokcen, Head of Data Science & Analytics at Maersk. The Maersk Group is a worldwide conglomerate that operates in 130 countries with a workforce of over 89,000 employees. Headquartered in Copenhagen, Denmark, with 2015 revenues of $40.3 billion, it owns Maersk Line, the world’s largest container shipping company, and is involved in a wide range of activities in the shipping, logistics, and the oil and gas industries.
“We want to make AI part of our digital journey,” says Gocken. “Strong technology platforms with AI capabilities help the data science and analytics people focus on the business logic, on the algorithms, and on churning models very quickly. These platforms give a head start not just to employees making decisions but also to our data scientists.”
Adds Donald Thompson, Maana’s founder and president: “We capture in a pragmatic way the knowledge of subject matter experts and business users and make it explicit so more people can take advantage of it.”
In a statement, Thompson said that the new version of Maana’s platform is “introducing our first collection of Knowledge Assistants and Knowledge Applications that really bring out the value of our user-guided and machine-assisted approach. People at all levels are empowered to rapidly gain the understanding they need in order to make the best decisions, while generating new knowledge assets (models) that others can use or build upon.”

What’s the Difference Between Artificial Intelligence, Machine Learning, and Deep Learning?
Over the past few years AI has exploded, and especially since 2015. Much of that has to do with the wide availability of GPUs that make parallel processing ever faster, cheaper, and more powerful. It also has to do with the simultaneous one-two punch of practically infinite storage and a flood of data of every stripe (that whole Big Data movement) – images, text, transactions, mapping data, you name it.
