There are many opinions about what matters most in machine learning. Some would say it’s the data, some would say it is the algorithms and equations used to train computers on that data. Still, others would say it is the formulation of the question itself that is most important in machine learning.
The last point of view is representative of a startup called Nyansa, composed of networking veterans and big data specialists who believe they have a better approach to network management than, say, Cisco Systems or Hewlett-Packard Enterprise.
The reason, according to chief technologist and co-founder Anand Srinivas, is because Nyansa figures out all the different parts of a system — not just the switches and wireless access points, but the applications as well, that can affect what an end user experiences.
“Our innovation is not inventing new machine learning algorithms, it is in terms of bringing machine-learning algorithms to a use case like networking,” Srinivas said in an interview with ZDNet on Monday. Srinivas holds a PhD in wireless networks and algorithms from MIT, and has held a number of industry positions, especially for software-defined networking, at firms such as Overture Networks, Plexxi, and Airvana.

Based in Palo Alto, four-and-half-year-old Nyansa sells tools to IT to monitor the health of the network, explain degradations of performance when they happen, and then propose solutions. Its tools run on Amazon’s AWS, though they can also be installed on-premise, with hooks back to the public cloud. The company has over 100 customers, representing over 10 million devices “under observation,” it says, across 200,000 access points from different vendors, on hundreds of production networks. Clients include Uber, Tesla, and Lululemon. It has been bankrolled by chip giant Intel’s investment arm, and Formation8, to the tune of $27 million.
Its machine learning tools are very simple, far less sophisticated or adventuresome than today’s deep learning neural network approaches. They include things such as logistic regression analysis, random forest searches, nearest-neighbor searches, and “cluster” analysis. “A lot of this is off-the-shelf stuff,” confesses Srinivas.
“It is more straightforward than deep learning; deep learning is not the right approach for us, not yet, not until we grab all the low-hanging fruit which the simpler kinds of machine learning algorithms can give us.”
Nyansa gathers petabytes of data from those millions of client devices and thousands of access points, and first establishes a baseline. How well does the network perform, in terms of things such as what percentage of users have a wireless connection issue, on average, or what percentage have a Citrix application connectivity issue? Some of these devices have no users, they are Internet-of-Things gadgets, such as a General Electric wireless patient monitor, or the wrenches used by Tesla on the shop floor in its Fremont facility. Telemetry data must be gathered from those devices as a baseline for performance.
“One way you can think of us is as a vertically-integrated Splunk,” says Srinivas, referring to the Big Data monitoring system that ingests and mines customer data. “We can take any type of data and tie it into our system, but we go one step further to solve customer use cases.”

By having data from multiple customers in the cloud, says Srinivas, a baseline can be set not just for a given customer but across an industry. “What’s good performance,” he asks rhetorically. For a given industry, “if the baseline is a 30 percent network performance connection failure, then 5 percent for a given customer may be fine for them.”
Once a baseline is established, deviations can be detected in order to determine if a problem is, say, a network problem per se, or rather an application problem. And once deviations from the baseline are established, predictions can be made. “Based on what other customers have done, what is our prediction for actions that have been most beneficial,” is how he describes it. By then observing how recommendations are carried out, and the effects, the system can move beyond mere correlation, the focus of a lot of machine learning, to a sense of causality.
“By automatically learning a baseline, and learning it everywhere, and doing it in the exact same way, we can give you a recommendation, and it will have an impact.”
“At first, perhaps it’s 80 percent correlation. But when a customer takes that action, that baseline will tell you the truth of whether the action made a difference; if it [performance] gets better, the recommendation by definition is correct. That feedback loop gets you back into causation.”

As to how they differ from Cisco or Hewlett, Srinivas sees the Nyansa system as more comprehensive in what it looks at than either one. “We don’t care who the vendor is for wireless [access points] or RADIUS or DNS or DHCP, we will take whatever data from whatever source, that is a fundamental difference.”
“Their data sources are limited to their own stuff.”
Srinivas offers the example of GE bedside wireless patient monitors in a hospital run by client Mission Health, a healthcare system serving North Carolina. It is not enough to say that a network is or is not performing at baseline. “The final thing that matters is, are those waveforms [of patient data from the monitors] getting back to the nurse, and is that nurse able to see the oxygen level on the screen. It doesn’t matter if the wireless signal is good, you can’t just baseline wireless, because the particular data source you care about, the monitor, has nothing to do with switches.”

The answer, then, to machine learning, in its simpler form and perhaps even its more complex incarnations, is how engaging with the complexity of situations builds understanding. “Even with deep learning, the magic is in tuning the deep learning network, knowing how to turn the knobs,” observes Srinivas. “The crux of it is experience, over time knowing exactly how to tune things.”

Indiana Is The First State To Sue TikTok Over Child Safety Worries
To tech-savvy and/or historically informed readers, the widespread concern about TikTok in the U.S. might smack of earlier moral panics. As mental health nonprofit Take This reports, it’s a matter of record that social media, video and tabletop games, clothing choices, music genres, and virtually anything else enjoyed by the young have been excoriated by American elders on one moral basis or another.
At the same time, serious questions have been raised about the safety of TikTok as a platform. We’ve reported in the past about the successes and failures of TikTok’s content moderation, from its largely hands-off, algorithmic approach to managing content to the borderline unethical treatment experienced by the human moderators the platform does possess. Content capable of generating severe psychological trauma in adult professional content managers certainly shouldn’t be emerging in children’s feeds.
Moderation and data security are also inescapably entwined. Hands-off moderation doesn’t just threaten the possibility of traumatic content in users’ feeds; it allows for sharing media at least some users are likely to see as unethical if not illegal. Add that to the documented pressures that Chinese law puts on social media platforms and it starts to seem like the Indiana lawsuit, right or wrong, at least has some kind of grounding.
Still, TikTok has answered critics and survived plenty of tough talk from the previous presidential administration. Whether it can continue to do so will depend both on the commitment of the platform’s user base and its ability to adapt to the requirements of American law.
How Fast Is The Electric Harley-Davidson Motorcycle Really?
According to Livewire, the ONE has some impressive speed and acceleration numbers, going from 0-60 mph in just three seconds and topping out at 110 mph. Sure, 110 mph doesn’t seem awfully fast, but Harley-Davidson motorcycles were never known for being fast. According to testing by CycleWorld, the Livewire ONE lives up to its reputation, accelerating from 0-60 mph in 3.1 seconds — a fraction of a second slower than the marketed number.
Interestingly, in terms of acceleration, the Livewire ONE is second only to the FXDR 114, which has a 0-60 mph time of only 2.5 seconds, according to Harley Davidson of Kingwood. Being quick off the line is par for the course for an electric motorcycle, though — there are no gears to cycle through, and electric motor torque is usually much higher at low RPM. The highest top speed for a production Harley-Davidson bike also goes to the FXDR 114, which tops out at a respectable 160 mph, according to Peterson’s Harley-Davidson. As far as the Livewire ONE’s 110 mph top speed, that’s par for the course for Harley-Davidson, with most everything except for the FXDR 114.
The Most Luxurious Features Of Mariah Carey’s 1.8 Million Dollar RV
Upon entering you are immediately met by a makeup station with an oversized mirror ringed by “true” makeup lights. On the opposite wall behind the seat is an offset television so the Queen of Christmas can watch her favorite program (through the mirror) while getting properly primped. Dark wood lines the floors, top and bottom (via HotCars).
This segues into a lounge with a curvy 15-foot custom couch ($7,000) and a 65″ Samsung 9000 connected to a Genelec studio-grade 5.1 surround sound system. The left side slides out 35 feet while the right slides out 25 feet to create a 600-square-foot space for her entourage.
The full gourmet kitchen includes a convection microwave, two-burner induction stove top, Sub-Zero hideaway fridge, and a $4,000 LeveLuk SD501 Platinum Kangen water system. Granite stairs lead from the kitchen to a second floor, where the roof pop-ups via hydraulics to reveal what designer RJ Anderson calls a “skyscraper on wheels” (per Daily Mail via AOL Celebrity Motor Homes).
Huge windows run down each side of the bus providing a nearly 360-degree uninterrupted panoramic view, while a 35-foot wrap-around couch seats 30 people. Not only can the lights be dimmed, but it comes with a color wheel that can turn the area into a proverbial nightclub. Big 60-inch televisions on either end of the room round out the entertainment area (via AOL Celebrity Motor Homes).
Anderson Mobile Estates also operates the 7744 Ranch, a resort outside Austin, Texas, where anyone can book a stay in a previously-owned-by-a-celebrity motor home. One of the five listed is “The Lounge.” However, a promotional video not only says it once belonged to Jennifer Lopez (not Mariah Carey) but looks precisely like Mariah Carey’s from the 2005 “Access Hollywood” segment.
Now, all we really want for Christmas is some clarification in this great camper caper.
