Skip-gram with negative sampling, a popular variant of Word2vec originally designed and tuned to create word embeddings for Natural Language Processing, has been used to create item embeddings with successful applications in recommendation. While these fields do not share the same type of data, neither evaluate on the same tasks, recommendation applications tend to use the same already tuned hyperparameters values, even if optimal hyperparameters values are often known to be data and task dependent. We thus investigate the marginal importance of each hyperparameter in a recommendation setting, with an extensive joint hyperparameter optimization on various datasets. Results reveal that optimizing neglected hyperparameters, namely negative sampling distribution, number of epochs, subsampling parameter and window-size, significantly improves performance on a recommendation task, and can increase it up to a factor of $10$.

Recently, The Spectator, in association with NatWest, brought together leading entrepreneurs, MPs and technology writers to discuss where Artificial Intelligence (AI) – or the fourth industrial revolution as it is often termed – is taking us.

In the last 20 years, flatscreen TVs have gone from high-priced novelty item to household mainstay. Not even counting Black Friday, you can get perfectly acceptable TVs for just a couple hundred bucks, and really astounding ones for not much more. It's no secret that along the way, the flatscreen market has become absolutely saturated. This has lead to what I would call "feature jousting." Almost every year, flatscreen TVs ship with some new "must-have" feature: The ability to play 3D movies (including dork-tastic 3D glasses), or built-in web browsers and streaming apps, or remotes with built-in voice search.

TORONTO, April 10, 2018 /CNW/ – Canada's trust levels in government, leaders and most information sources remain stable and strong, but social media networks and the artificial intelligence (AI) sector are both at a crossroads, according to the 2018 Proof Inc.

BBC Radio 1 has announced a major overhaul of its line-up, with the weekend schedule now starting on Fridays. Nick Grimshaw, Clara Amfo and Greg James will go down to hosting four shows a week as a result. New Friday shows have been announced for Maya Jama and The Saturdays' Mollie King as part of the changes, and Scott Mills will now host the chart show. Dev and Alice Levine will present the breakfast show from Friday to Sunday. Ben Cooper, controller of BBC Radio 1, said: "The weekend will start here at Radio 1 on a Friday morning giving our young audience that feel-good factor a day early. "It's our job at Radio 1 to reinvent the way young people listen to the radio, to disrupt traditional thinking and to look for new ways in which to grow audiences." The new schedule comes into effect in June. It's unclear how the schedule changes might affect the daytime hosts' current salaries, but a BBC spokesman said all presenters on the station are paid fairly. This marks the first time in Radio 1's history that the daytime DJs will be on a four-day week, although Chris Evans once tried to take Fridays off when he was hosting the breakfast show. In the late 1990s, he famously asked if he could host the programme only from Monday to Thursday - a request which was denied by then-controller Matthew Bannister. Jama joined the station earlier this year as the presenter of Radio 1's Greatest Hits. King has been appearing as a guest presenter with Edmondson in recent weeks but will now officially be a permanent fixture on the station. The singer, who appeared on the most recent series of Strictly Come Dancing, said: "I've grown up listening to Radio 1 and I can't wait to be one of the team.

LG's artificial intelligence technology, ThinQ, first made its way to the Korean company's phones as part of the V30S. Now, the brand has confirmed that ThinQ is also coming to LG's flagship G-series, specifically the G7 that's debuting in New York on May 2nd and Seoul on May 3rd. According to the company's announcement, the G7 ThinQ's'Empathic AI' -- that's how LG describes its artificial intelligence, which it says is capable of human-like thinking to a certain extent -- is better than its predecessor's. We'll have to wait for the device's official launch to know how exactly it's better than the V30's, though. LG didn't expound on the new phone's features, but Israeli news site YNET got the chance to play with it a bit when it showed up in Barcelona during MWC.
