Learning about machine learning

Everywhere we look, machine learning is in the news. It’s driving cars and beating the world’s best Go players. Whether we are aware of it or not, it’s in our lives–understanding our voices and identifying our pictures.

Our goal of being able to measure the performance of hardware and software that does machine learning seems more relevant than ever. Our challenge is to scan the vast landscape that is machine learning, and identify which elements to measure first.

There is a natural temptation to see machine learning as being all about neural networks such as AlexNet and GoogLeNet. However, new innovations appear all the time and lots of important work with more classic machine learning techniques is also underway. (Classic machine learning being anything more than a few years old!) Recursive neural networks used for language translation, reinforcement learning used in robotics, and support vector machine (SVM) learning used in text recognition are just a few examples among the wide array of algorithms to consider.

Creating a benchmark or set of benchmarks to cover all those areas, however, is unlikely to be possible. Certainly, creating such an ambitious tool would take so long that it would be of limited usefulness.

Our current thinking is to begin with a small set of representative algorithms. The challenge, of course, is identifying them. That’s where you come in. What would you like to start with?

We anticipate that the benchmark will focus on the types of inference learning and light training that are likely to occur on edge devices. Extensive training with large datasets takes place in data centers or on systems with extraordinary computing capabilities. We’re interested in use cases that will stress the local processing power of everyday devices.

We are, of course, reaching out to folks in the machine learning field—including those in academia, those who create the underlying hardware and software, and those who make the products that rely on that hardware and software.

What do you think?

VR and AR at Mobile World Congress 2017

Spotting the virtual reality (VR) and augmented reality (AR) demos at the recent Mobile World Congress (MWC) in Barcelona was easy: all you had to do was look for the long queues of people waiting to put on a headset and see another world. Though the demos ranged from games to simulated roller-coaster rides to simple how-to tools, the interest of the crowd was always high. A lot of the attraction was clearly due to the tools’ relative novelty, but many people seemed focused on using the technologies to create commercially viable products.

Both VR and AR involve a great deal of graphics and data movement, so they can be quite computationally demanding. Right now, that’s not a problem, because most applications and demos are hooked directly to powerful computers. As these technologies become more pervasive, however, they’re going to find their way into our devices, which will almost certainly do some of the processing even as the bulk of the work happens on servers in the cloud. The better the AR and VR experiences our devices can support, the happier we’re likely to be with those technologies.

Along with the crowds at MWC, many of us in the BenchmarkXPRT Development Community are enthusiastic about VR and AR, which is why we’ve been monitoring these fields for some time. We’ve even worked with a group of NC State University students to produce a sample VR workload. If you have thoughts on how we might best support VR and AR, please contact us. Meanwhile, we’ll continue to track both closely and work to get the XPRTs ready to measure how well devices handle these technologies.

CES 2017

I’ve attended many tech shows over the years, but this year’s CES has more energy than any I’ve attended in a long time. Part of the energy is the breadth of products. There are amazingly slim TVs that make my TV at home, which I thought was slim, look fat. And, there are beautiful 8K TVs that make my new 4K one feel old.

I’m seeing all manner of smartphones. I’m seeing mobile remote presence devices such as the one from Beam, and after seeing the latest Fenix 5 from Garmin, I think I’ve found my next smartwatch.

There are many differing devices and approaches to VR and AR. There are drones everywhere. And, lots of massage chairs.

There are also plenty of products, let’s call them longshots, that contribute to the Wild West feel of the show. Maybe you’d like the Hydreon FakeTV, a small device to make it seem like a TV is on in your house to keep away burglars? Or Dr. Fuji’s Body Shaper, a vibrating platform to “accelerate your workout”?

Another part of the dynamic feeling is the breadth of vendors. Almost all the big tech vendors are here, except for Apple, of course. The excitement for me, however, is the small vendors displaying things that may well never see the light of day, but give glimpses of the future. For example, while I doubt most of the drone vendors at CES will be around in a few years, I think the trend toward small, inexpensive selfie drones will be.

The main reason for the energy at this year’s CES could be the convergence of multiple big industries. The most obvious example of this phenomenon is the large auto presence. Cars have been at CES before—the first time I drove my current car, a BMW i3, was at CES 2014—but this time around they seem to really want to make a statement. Faraday Future is making a splash by trying to be the next Tesla with its FF91.

Multiple vendors, including VW, Nissan, Toyota, and Mercedes, have concept cars on display—most of them are electric and all of them are heavy on technology. The biggest tech they’re touting is autonomous driving. The auto companies are showing their products while companies like NVIDIA, Intel, and Magic Eye are displaying the tech they have as well.

Regardless of the source of the energy at this CES, I see many opportunities for the existing XPRTs to continue to be important resources. I also see how important emerging technologies like machine learning and VR/AR are going to be and how the XPRTs can be of help there as well.

Exciting times!
