Automatic discovery of tactics in spatio-temporal soccer match data

Automatic discovery of tactics in spatio-temporal soccer match data Decroos et al., KDD’18

Here’s a fun paper to end the week. Data collection from sporting events is now widespread. This fuels an endless thirst for team and player statistics. In terms of football (which shall refer to the game of soccer throughout this write-up) that leads to metrics such as completed passes, distance covered, intercepts, shots-on-goal, and so on. Decroos et al. want to go one level deeper though, and use the data to uncover team tactics. The state of the art today for tactical analysis still involves watching hours of video footage.

This paper focuses on the problem of detecting tactics from professional soccer matches based on spatio-temporal data.

Now when I think of tactics, a key component in my mind is the team shape and movement of players off the ball. Unfortunately Decroos et al., don’t have the data available to analyse that. So they have to do what they can based on more limited information.

Our dataset consists of event data for the English Premier League for the 2015/2016 season. This event data was manually collected by humans who watch video feeds of the matches Continue reading

Happy National Coming Out Day: Stories from Proudflare

Today is the 30th Anniversary of National Coming Out Day. We wanted to share some coming out stories from members of Proudflare and draw attention to resources the Human Rights Campaign provides to those who are thinking about coming out or wish to be supportive of those who come out to them.

About National Coming Out Day

On October 11, 1987, about 500,000 people marched on Washington for Lesbian and Gay Rights. This was the second demonstration of this type in the capital and it resulted in the formation of several LGBTQ organizations.

In the late 1980s, the LGBTQ community recognized that they often reacted defensively to anti LGBTQIA+ actions and the community came up with the idea of a national day for celebrating coming out. The anniversary of the 1987 march was chosen as that national day.

Each year on October 11th, National Coming Out Day continues to promote a safe world for LGBTQ individuals to live truthfully and openly.

IDG Contributor Network: Introducing Named Data Networking

While computing, storage and programming have dramatically changed and become simpler and cheaper over the last 20 years, however, IP networking has not. IP networking is still stuck in the era of mid-1990s.Realistically, when I look at ways to upgrade or improve a network, the approach falls into two separate buckets. One is the tactical move and the other is strategic. For example, when I look at IPv6, I see this as a tactical move. There aren’t many business value-adds.In fact, there are opposites such as additional overheads and minimal internetworking QoS between IPv4 & v6 with zero application awareness and still a lack of security. Here, I do not intend to say that one should not upgrade to IPv6, it does give you more IP addresses (if you need them) and better multicast capabilities but it’s a tactical move.To read this article in full, please click here

Worth Reading: Upstream visibility

The most common approach for displaying BGP data collected is to use an animated graph, for example, BGPlay. In this type of visualization, each node of the graph is an AS and each link is a peering session among ASes. Every time a BGP update is applied, the links in the graph change according to the new status. —Massimo Candela @APNIC

Private cloud spending is increasing, not decreasing

Once again, IDC has thrown cold water on the notion that enterprises are looking to shut down their data centers and instead are looking to grow them. And a new form of IT spending is taking place.The latest worldwide market study by International Data Corporation (IDC) found revenue from sales of IT infrastructure equipment grew 48.4 percent year over year in the second quarter of 2018 to $15.4 billion.Quarterly spending on public cloud IT infrastructure was $10.9 billion in the second quarter of 2018, a 58.9 percent year-over-year growth, while private cloud spending reached $4.6 billion, an increase of 28.2 percent year over year.[ Check out What is hybrid cloud computing and learn what you need to know about multi-cloud. | Get regularly scheduled insights by signing up for Network World newsletters. ] By end of the year, IDC projects public cloud spending will account for 68.2 percent of total IT equipment spending, growing at an annual rate of 36.9 percent. That’s not surprising, though, as Amazon, Microsoft, Google, etc., buy servers in the tens of thousands of units.To read this article in full, please click here

Radical shake-up proposed for the internet

Changes may be in the cards for the internet. Primarily, the global information system that we know as the World Wide Web could be up for some radical blockchain-concept re-thinking. It could take us back in time, but in a good way, according to some experts.Mass decentralization, which includes the shifting the control of data from corporations to individuals, is what they propose.“If you think of our existing web, it was originally designed to be decentralized, but over the years, we've come to see 90 percent of the traffic going through three or four different companies,” says Mitra Ardron, Technical Lead for Decentralization, at Internet Archive, which hosted the Decentralized Web Summit in San Francisco this summer. He was quoted on the conference’s website.To read this article in full, please click here

Technologies that Didn’t: The OSI Protocol Stack

The Open Systems Interconnect (OSI) model is the most often taught model of data transmission—although it is not all that useful in terms of describing how modern networks work. What many engineers who have come into network engineering more recently do not know is there was an entire protocol suite that went with the OSI model. Each of the layers within the OSI model, in fact, had multiple protocols specified to fill the functions of that layer. For instance, X.25, while older than the OSI model, was adopted into the OSI suite to provide point-to-point connectivity over some specific kinds of physical circuits. Moving up the stack a little, there were several protocols that provided much the same service as the widely used Internet Protocol (IP). @ECI
