Most tech costs a fair chunk of change (the PS5 Pro and iPad Pro jump to mind), but some smaller electronics are (almost) as exciting. Now that Cyber Monday is here, we've found dozens of deals on inexpensive electronics and accessories that cost less than 50. Unlike other lists you may find today, this one is made up of items we've tested, reviewed or otherwise recommend in our buying and gift guides -- so we think they're actually worth your money. Amazon Echo Pop (2023) for 18 ( 22 off): Amazon's smallest Echo will fit in any room in your home, so Alexa can add things to your shopping list, set a timer, or answer questions (like "What's a bomb cyclone?" or "Who is Penelope Cruz married to?") from anywhere. Anker Nano Charger 30W USB-C for 13 ( 7 off): This compact 30-watt wall charger is smaller than others of its wattage and can speedily juice up an iPhone or Android handset. Anker is one of Engadget's most recommended accessory brands and this is the model we picked for our fast charger guide. Get the same deal at Anker with an auto-applied code. Anker Nano power bank with built-in USB-C connector for 16 ( 4 off): It's the size of an old-timey lipstick case but packs enough juice (and its own USB-C plug) to get a dying smartphone back in service with at least a half charge.

The expensive tech gets all the attention -- thousand-dollar phones and 500 tablets. But the supporting players, the cables and batteries and chargers that make those devices work properly, are just as important. Right now for Black Friday, many of those smaller gadgets are on sale for less than 50 even after the day has passed. And there are even some standalone devices like earbuds and smart speakers that fall well below the threshold. We've tested scads of these smaller, less expensive tech for Engadget buying guides, including the best power banks, iPad accessories, smart plugs and microSD cards. Here, we've gathered up all the Black Friday tech deals under 50 that you can still get on gadgets we recommend. Amazon Echo Pop (2023) for 18 ( 22 off): Amazon's smallest Echo will fit in any room in your home, so Alexa can add things to your shopping list, set a timer, or answer questions (like "What's a bomb cyclone?" or "Who is Penelope Cruz married to?") from anywhere.

To combat the rising energy consumption of recommender systems we implement a novel alternative for k-fold cross validation. This alternative, named e-fold cross validation, aims to minimize the number of folds to achieve a reduction in power usage while keeping the reliability and robustness of the test results high. We tested our method on 5 recommender system algorithms across 6 datasets and compared it with 10-fold cross validation. On average e-fold cross validation only needed 41.5% of the energy that 10-fold cross validation would need, while it's results only differed by 1.81%. We conclude that e-fold cross validation is a promising approach that has the potential to be an energy efficient but still reliable alternative to k-fold cross validation.

Black Friday deals don't usually stick around, but this one did. It's almost like we knew you were still stuck on Windows 10 or the free version of Windows 11--missing out on the AI assistant, advanced multitasking, and exclusive security features. You're being given a second chance, so don't pass it up: Buy Windows 11 Pro now for 19.97 (reg. Less than 50 codes are left after Black Friday, but there's still time to upgrade with this 92 percent discount. If you're coming from Windows 10, you'll notice the redesigned look first.

In the field of Recommender Systems (RS), neural collaborative filtering represents a significant milestone by combining matrix factorization and deep neural networks to achieve promising results. Traditional methods like matrix factorization often rely on linear models, limiting their capability to capture complex interactions between users, items, and contexts. This limitation becomes particularly evident with high-dimensional datasets due to their inability to capture relationships among users, items, and contextual factors. Unsupervised learning and dimension reduction tasks utilize autoencoders, neural network-based models renowned for their capacity to encode and decode data. Autoencoders learn latent representations of inputs, reducing dataset size while capturing complex patterns and features. In this paper, we introduce a framework that combines neural contextual matrix factorization with autoencoders to predict user ratings for items. We provide a comprehensive overview of the framework's design and implementation. To evaluate its performance, we conduct experiments on various real-world datasets and compare the results against state-of-the-art approaches. We also extend the concept of conformal prediction to prediction rating and introduce a Conformal Prediction Rating (CPR). For RS, we define the nonconformity score, a key concept of conformal prediction, and demonstrate that it satisfies the exchangeability property.

Movie posters are not just decorative; they are meticulously designed to capture the essence of a movie, such as its genre, storyline, and tone/vibe. For decades, movie posters have graced cinema walls, billboards, and now our digital screens as a form of digital posters. Movie genre classification plays a pivotal role in film marketing, audience engagement, and recommendation systems. Previous explorations into movie genre classification have been mostly examined in plot summaries, subtitles, trailers and movie scenes. Movie posters provide a pre-release tantalizing glimpse into a film's key aspects, which can ignite public interest. In this paper, we presented the framework that exploits movie posters from a visual and textual perspective to address the multilabel movie genre classification problem. Firstly, we extracted text from movie posters using an OCR and retrieved the relevant embedding. Next, we introduce a cross-attention-based fusion module to allocate attention weights to visual and textual embedding. In validating our framework, we utilized 13882 posters sourced from the Internet Movie Database (IMDb). The outcomes of the experiments indicate that our model exhibited promising performance and outperformed even some prominent contemporary architectures.

When it comes to new tech, 50 doesn't get you a lot-- except perhaps during Black Friday sales. Surprisingly, quite a few of the smaller electronics and accessories we recommend are currently on sale right now for less than 50. These deals include picks from our guides to accessories guides, portable batteries, budget earbuds and smart speakers. Everything on this list has earned the Engadget nod of approval -- like Anker's Nano charger ( 13), Belkin's AirTag holder ( 15) and PopSocket phone grips ( 15). These picks come from stuff we tested for our reviews and buying guides or from personal use and brands we know to be reputable -- so you don't have to guess whether these Black Friday tech deals are worth your (less than) 50. Amazon Echo Pop (2023) for 18 ( 22 off): Amazon's smallest Echo will fit in any room in your home, so Alexa can add things to your shopping list, set a timer, or answer questions (like "What's a bomb cyclone?" or "Who is Penelope Cruz married to?") from anywhere.

According to my imprecise calculations, there are approximately a zillion speakers on sale for Black Friday. So how can a mere human know which ones are worthy and which will make music sound like it's emanating from a tin can? We've done our part by testing and reviewing dozens of different options and putting the best of the lot into handy buying guides for smart speakers, soundbars and portable Bluetooth speakers. This is an even more rarefied list, made up of the speakers we recommend -- that are also seeing notable discounts. If you need a new way to listen to music, a soundbar to help suss out the dialogue on your TV or a smart speaker to fulfill your demands, read on for the best Black Friday speaker deals. Portable Bluetooth speakers make it easy for you to bring the music where plugs don't reach -- a picnic, the front stoop, an aimless wander along the North Country Trail.

During the trial the court heard how the former East of England Ambulance Service call handler had used stickers on his work ID card to hide his more junior role. Kadolski told the woman he raped that he was a paramedic, and she said he had used pictures of himself wearing a paramedic's uniform on his online dating profile. "I remember his photos in paramedic gear... you wouldn't assume that [emergency workers] would do anything bad," she said. Under the Health Professions Order 2001, it is an offence for a person to use a health title to which they are not entitled, which includes paramedic. However, the victim has called for a new law, similar to what exists for police officers, to specifically stop people being able to pose as a paramedic.
