'We had people come just to see it': Amazon delivers its first UK parcels by drone

BBC News

'We had people come just to see it': Amazon delivers its first UK parcels by drone Amazon has become the first retailer in the UK to start a drone delivery service with a limited launch in Darlington, County Durham. Packages weighing less than 5lb (2.2kg) and containing everyday items such as beauty products, batteries and cables are now being delivered within a 7.5 mile (12km) radius of Amazon's fulfilment centre. The tech giant is convinced there is demand for ultra-fast deliveries and hopes to slowly expand the service. Rob Shield let Amazon use an Airbnb on his farm for its first test runs. Initially it was a novelty, so we were ordering everything under the sun, he says.


NASCAR Cup champ Kyle Larson rips Ross Chastain's video-game move: 'It's embarrassing'

FOX News

Fox News Flash top headlines are here. Check out what's clicking on Foxnews.com. Ross Chastain's incredible move to sneak into the Championship Four at Martinsville Speedway on Sunday did not sit well with all of his fellow NASCAR colleagues. Chastain rode the wall to gain momentum and beat out Denny Hamlin for fifth place in the Xfinity 500. Hamlin failed to make the championship round and instead, Chastain will join race winner Christopher Bell, Joey Logano and Chase Elliott for the final event in Phoenix next week.


NASCAR playoffs: Hamlin holds off Larson's wall-banging 'video game' move to win Southern 500

FOX News

More than 195 drivers have won a Cup Series race since NASCAR started in 1948, but who has won the most? Kyle Larson put it all on the line … and the wall. Denny Hamlin does a burnout after winning a NASCAR Cup Series auto race Sunday, Sept. 5, 2021, in Darlington, S.C. (AP Photo/John Amis) (AP) The Hendrick Motorsports driver made a last-ditch effort to pass Denny Hamlin in the final turns of the Southern 500 that looked like something out of a video game race. Larson led the most laps during the race, but was behind Hamlin near the end and unable to get by, so he went full throttle and ran his car against the wall in turns three and four as they approached the checkered flag attempting to pass him on the outside with smoke coming off the car. "I gave it everything I had, I didn't want to wreck him, I just wanted to, you know, get to his outside there," Larson said.


50 Years of Test (Un)fairness: Lessons for Machine Learning

Hutchinson, Ben, Mitchell, Margaret

arXiv.org Artificial Intelligence

Quantitative definitions of what is unfair and what is fair have been introduced in multiple disciplines for well over 50 years, including in education, hiring, and machine learning. We trace how the notion of fairness has been defined within the testing communities of education and hiring over the past half century, exploring the cultural and social context in which different fairness definitions have emerged. In some cases, earlier definitions of fairness are similar or identical to definitions of fairness in current machine learning research, and foreshadow current formal work. In other cases, insights into what fairness means and how to measure it have largely gone overlooked. We compare past and current notions of fairness along several dimensions, including the fairness criteria, the focus of the criteria (e.g., a test, a model, or its use), the relationship of fairness to individuals, groups, and subgroups, and the mathematical method for measuring fairness (e.g., classification, regression). This work points the way towards future research and measurement of (un)fairness that builds from our modern understanding of fairness while incorporating insights from the past.


SOME THEOREM-PROVING STRATEGIES BASED ON THE RESOLUTION PRINCIPLE JARED L. DARLINGTON

AI Classics

The formulation of the resolution principle by J. A. Robinson (1965a) has provided the impetus for a number of recent efforts in automatic theoremproving. In particular, the program PG1 (Wos et al. 1964, 1965), written by L. Wos, G. A. Robinson and D. F. Carson for the Control Data 3600, utilises the resolution principle in conjunction with a'unit preference strategy' and a'set of support strategy' to produce efficient proofs in first-order functional logic and group theory. These programs have generated proofs of some interesting propositions of number theory, in addition to theorems of first-order functional logic and group theory. A'literal' is an n-place predicate expression F(xi, x2,.-.., x) or its negation F(xi, x2,., x „) whose arguments are individual variables, individual constants, or functional expressions. Quantifiers do not occur in these formulae, since existentially quantified variables have been replaced by functions of universally quantified ones, and the remaining variables may therefore be taken as universally quantified.

For example, the number-theoretic proposition'For all x and y, if x is a divisor of y then there exists some z such that x times z equals y' may be symbolised as D(x, y)v T(x, f(x, y), y) in which D(x, y)' stands for x is a divisor of y' and 7(x, y, z)' stands for'x times y equals z'.
