“The team at Oak Ridge says Summit is the first supercomputer designed from the ground up to run AI applications, such as machine learning and neural networks. It has over 27,000 GPU chips from Nvidia, whose products have supercharged plenty of AI applications, and also includes some of IBM’s Power9 chips, which the company launched last year specifically for AI workloads. There’s also an ultrafast communications link for shipping data between these silicon workhorses.
Bob Picciano of IBM says all this allows Summit to run some applications up to 10 times faster than Titan while using only 50 percent more electrical power. Among the AI-related projects slated to run on the new supercomputer is one that will crunch through huge volumes of written reports and medical images to try to identify possible relationships between genes and cancer. Another will try to identify genetic traits that could predispose people to opioid addiction and other afflictions”.

“Three main factors determine what you see in your Instagram feed:
- Interest: How much Instagram predicts you’ll care about a post, with higher ranking for what matters to you, determined by past behavior on similar content and potentially machine vision analyzing the actual content of the post.
- Recency: How recently the post was shared, with prioritization for timely posts over weeks-old ones.
- Relationship: How close you are to the person who shared it, with higher ranking for people you’ve interacted with a lot in the past on Instagram, such as by commenting on their posts or being tagged together in photos.
Beyond those core factors, three additional signals that influence rankings are:
- Frequency: How often you open Instagram, as it will try to show you the best posts since your last visit.
- Following: If you follow a lot of people, Instagram will be picking from a wider breadth of authors so you might see less of any specific person.
- Usage: How long you spend on Instagram determines if you’re just seeing the best posts during short sessions, or it’s digging deeper into its catalog if you spend more total time browsing”.

“People say nothing has changed: that there is still mass surveillance. That is not how you measure change. Look back before 2013 and look at what has happened since. Everything changed. The government and corporate sector preyed on our ignorance. But now we know. People are aware now. People are still powerless to stop it but we are trying. The revelations made the fight more even” – Edward Snowden.

“After connecting to Facebook, the BlackBerry Hub app was able to retrieve detailed data on 556 of Mr. LaForgia’s friends, including relationship status, religious and political leanings and events they planned to attend. Facebook has said that it cut off third parties’ access to this type of information in 2015, but that it does not consider BlackBerry a third party in this case”.

“Facial recognition software used by the UK’s biggest police force has returned false positives in more than 98 per cent of alerts generated, The Independent can reveal, with the country’s biometrics regulator calling it “not yet fit for use”. The Metropolitan Police’s system has produced 104 alerts of which only two were later confirmed to be positive matches, a freedom of information request showed. In its response the force said it did not consider the inaccurate matches “false positives” because alerts were checked a second time after they occurred”.

“In one particularly brazen example, ads were run promoting both a “Pro-Beyonce Protest Rally” and an “Anti-Beyonce Protest Rally” scheduled for the same time time and place following the controversy over the artist’s performance at the 2016 Super Bowl. The pro-Beyoncé ad was targeted at users designated as having African American behaviors. The anti-Beyoncé ad was targeted narrowly at people who had studied to become a police officer or whose job title matched a list of law enforcement or military titles, including officer, colonel, major general (United States), master sergeant, commander (United States), sergeant, brigadier general, petty officer, chief petty officer, lieutenant commander, squadron leader, 911 dispatcher or rear admiral”.

“Le logo de SenseTime est rarement visible, même en Chine, où l’entreprise est pourtant la plus active. Sa technologie se trouve cependant derrière nombre de logiciels et d’applications populaires. Suning, un vendeur de produits électroménagers chinois à succès, a lancé l’année dernière des magasins autonomes, sans vendeurs. Le paiement par reconnaissance faciale y est possible grâce à SenseTime. Le spécialiste de l’IA aide aussi l’opérateur du métro de Shanghaï à analyser les flux de passagers.Mais le chiffre d’affaires de SenseTime provient essentiellement d’applications moins impressionnantes. L’entreprise fournit la technologie de reconnaissance faciale des principaux constructeurs chinois de smartphones – Huawei, Oppo, Xiaomi et Vivo”.
