In the last three decades, we have seen a significant increase in trading goods and services through online auctions. However, this business created an attractive environment for malicious moneymakers who can commit different types of fraud activities, such as Shill Bidding (SB). The latter is predominant across many auctions but this type of fraud is difficult to detect due to its similarity to normal bidding behaviour. The unavailability of SB datasets makes the development of SB detection and classification models burdensome. Furthermore, to implement efficient SB detection models, we should produce SB data from actual auctions of commercial sites. In this study, we first scraped a large number of eBay auctions of a popular product. After preprocessing the raw auction data, we build a high-quality SB dataset based on the most reliable SB strategies. The aim of our research is to share the preprocessed auction dataset as well as the SB training (unlabelled) dataset, thereby researchers can apply various machine learning techniques by using authentic data of auctions and fraud.

The future of audio isn't wired--and Apple knows it. The iPhone's headphone jack, a beloved former hardware accessory, was eliminated with the iPhone 7. "It's clear to me that Apple has forceful, but considered opinions about how the next generation of phones should fit into our lives," the Verge's Nilay Patel wrote in his review of the phone in 2016. "But it's also clear that the iPhone 7 is a transitional step to that vision of the future, not a complete expression of it." We learned more about what that future would encompass when Apple also introduced AirPods, its wireless, Siri-imbued earbuds. However, since the launch of the iPhone 7, Apple has babied those of us not ready commit to the wireless audio way of life by including Lightning adapter–based white earbuds and a Lightning-to-3.5 mm jack dongle in the box with new iPhones.

Inertial sensors play a pivotal role in indoor localization, which in turn lays the foundation for pervasive personal applications. However, low-cost inertial sensors, as commonly found in smartphones, are plagued by bias and noise, which leads to unbounded growth in error when accelerations are double integrated to obtain displacement. Small errors in state estimation propagate to make odometry virtually unusable in a matter of seconds. We propose to break the cycle of continuous integration, and instead segment inertial data into independent windows. The challenge becomes estimating the latent states of each window, such as velocity and orientation, as these are not directly observable from sensor data. We demonstrate how to formulate this as an optimization problem, and show how deep recurrent neural networks can yield highly accurate trajectories, outperforming state-of-the-art shallow techniques, on a wide range of tests and attachments. In particular, we demonstrate that IONet can generalize to estimate odometry for non-periodic motion, such as a shopping trolley or baby-stroller, an extremely challenging task for existing techniques.

Two friends have cracked the facial recognition on the £999 ($999) iPhone X after discovering it accepted both their faces. Joe Clayton, 23, was shocked when best friend Brad Butcher, 22, unlocked Apple's most expensive phone just by looking at it, beating one in a million odds. The construction site manager had set up the gadget so only his face appearing in front of the camera would unlock the screen. But the phone will also give Mr Butcher access - allowing him to make contactless payments, send messages and make calls - despite Apple claiming the chances of a mix up are one in a million. Two friends have cracked the facial recognition on the £999 ($999) iPhone X after discovering it accepted both their faces.

Update: We've had the iPhone X on test for over a day now, and we've got a video with our early thoughts thus far in our iPhone X 24 hour diary. Early findings show a strong Face ID performance and an impressive screen - does it do enough for iPhone fans though? Apple's long-awaited iPhone X pre-orders are now live, which means the official release date is next week: Friday November 3. You may not be able to buy Apple's highly anticipated smartphone right away. Finding it in stock on launch day is going to be extremely difficult, though we are tracking iPhone X pre-orders in the US, and the best iPhone X deals in the UK. Apple claims that the iPhone X, which is pronounced'iPhone 10', is worth your money and any extra wait time due to its revolutionary new features. The iPhone X wasn't the only smartphone announced by CEO Tim Cook at Apple's recent September 12 launch event.

We take a look at the iPhone X and break down the new features. The iPhone X lacks a home button. As the first iPhone to ditch the home button, go all-in on facial recognition and, oh yeah, crack $1,000, the iPhone X has generated more palpable interest than any iPhone since the original a decade ago. The basics: It has a beautiful edge-to-edge 5.8-inch OLED display, a glass front and back, and a camera system that's very similar to the iPhone 8 Plus camera I favorably reviewed a few weeks ago, with the clever Portrait Lighting effects on those phones now also available for selfies on the X. Supplies are tight, but if you're able to get one, it will cost $999 with 64GB or $1,149 with 256GB.

If you're looking to get your hands on an iPhone X, you need to be quick. Pre-orders for Apple's latest flagship smartphone launched today at 8am BST (3am ET/ 12am PT), but experts have warned of a'catastrophic stock shortage'. The iPhone X was announced at an exclusive media event in September and the much-hyped devices are expected to ship on November 3. But an inside source has warned that a'chronic lack' of iPhone X handsets available worldwide after launch will see many unable to get hold of one until 2018. The source, reportedly from a popular phone retailer, has given advice to those looking to get their hands on the £999 ($999) device before Christmas.

Apple announced three new iPhones this month: the iPhone 8, the iPhone 8 Plus, and the high-end iPhone X. Those three phones start at $699, $799, and $999, respectively. Based on the relatively diminutive launch-day lines for the iPhone 8, it seems likely that most people are waiting for the release of Apple's high-end iPhone X, which debuts November 3. That said, there are several reasons it's worth considering an iPhone 8 instead of holding out for the iPhone X: The iPhone 8 and 8 Plus are powered by the same brains as the iPhone X. This is probably the most important reason to consider the iPhone 8 and 8 Plus over the iPhone X: Functionally, they're all identical.

In a video introducing the iPhone X, Apple design chief Jony Ive speaks in his usual sonorous tones about features like polished stainless steel and new formulations of glass. Twice, he also calls out a feature of the $999 device that its owners will never see: the A11 "bionic" processor powering the phone. The new chip's prominence reflects Apple's deepening investment in chip design. Last week the company also revealed it had built new custom chips or chip components for artificial intelligence, graphics, and video. And Apple highlighted two new chips in its refreshed smartwatch, suggesting they helped the company add a cellular connection to the device without hurting its battery life.

Apple said: "People were handling the device for the stage demo ahead of time and didn't realise Face ID was trying to authenticate their face". So this week Apple ended months of rumours and speculation with the announcement of not just two phones replacing its now year old iPhones, but three, properly celebrating the tenth anniversary of the iPhone with a newly named iPhone X, a model that basically aims to be the one everyone wants, but will of course cost the proverbial arm and leg. Al Franken of Minnesota chose to put several of them directly to Apple CEO Tim Cook, a day after the company announced that its iPhone X would unlock with Face ID. The company went head-to-head with the Federal Bureau of Investigation over the agency's demand that Apple unlock an iPhone belonging to one of the terrorists behind the San Bernardino, California, shootings. Apple Inc's highly anticipated iPhone X features a slew of innovations but delayed availability could hurt holiday-quarter sales.
