Traffic classification, a technique for assigning network flows to predefined categories, has been widely deployed in enterprise and carrier networks. With the massive adoption of mobile devices, encryption is increasingly used in mobile applications to address privacy concerns. Consequently, traditional methods such as Deep Packet Inspection (DPI) fail to distinguish encrypted traffic. To tackle this challenge, Artificial Intelligence (AI), in particular Machine Learning (ML), has emerged as a promising solution for encrypted traffic classification. A crucial prerequisite for any ML-based approach is traffic data cleaning, which removes flows that are not useful for training (e.g., irrelevant protocols, background activity, control-plane messages, and long-lived sessions). Existing cleaning solutions depend on manual inspection of every captured packet, making the process both costly and time-consuming. In this poster, we present an unsupervised framework that automatically cleans encrypted mobile traffic. Evaluation on real-world datasets shows that our framework incurs only a 2%~2.5% reduction in classification accuracy compared with manual cleaning. These results demonstrate that our method offers an efficient and effective preprocessing step for ML-based encrypted traffic classification.

Robotic pool cleaners have revolutionized pool care, eliminating the back-breaking routine of manual vacuuming, scrubbing, and brushing. Today's models don't just clean -- they maintain a consistently pristine pool with minimal human effort. Technology in this space has advanced rapidly. The newest generation offers greater efficiency, longer runtimes, and pinpoint navigation for faster, more thorough results. Two standout examples are Aiper's Scuba X1 and Surfer S2, designed to work together for a complete, floor-to-surface clean.

The best vacuums are lightweight with strong filtration systems and multiple attachments. Keeping your home spotless can sometimes feel like a never-ending battle, but with the right vacuum, you can actually make cleaning easy. Whether you're dealing with pet hair, constant dust and kids' messes, a powerful vacuum is your best ally. We've done a deep dive into the best vacuums on the market, from Dyson to Shark, Miele and other well-known brands. There are lightweight options, hands-free options and vacuums that are extra-tough on pet hair.

At the 1933 World's Fair in Chicago, an exhibit called The Home of Tomorrow laid out a vision of a futuristic living space. It included outlandish predictions including personal helicopter pads, but it also foreshadowed central air conditioning, automatic dishwashers, and other innovations that have become integral parts of modern life. As we envision the home of the future, it's easy to get caught up in sci-fi-inspired predictions of fully autonomous homes serviced by robotic butlers and disembodied virtual assistants that remove the humanity from our living spaces. Here at Popular Science, we reject that vision. For the inaugural Home of the Future Awards, we have selected 25 products that augment life at home by making it more efficient, affordable, accessible, and--ultimately--more enjoyable. We test, preview, and evaluate hundreds of products per year and these products deserve a chance to cohabitate with you and the people who matter to you. A flat top grill is one of the most versatile ways to cook just about anything from pancakes to burgers, but temperature control is key.

Recent studies show that in supervised fine-tuning (SFT) of large language models (LLMs), data quality matters more than quantity. While most data cleaning methods concentrate on filtering entire samples, the quality of individual tokens within a sample can vary significantly. After pre-training, even in high-quality samples, patterns or phrases that are not task-related can be redundant or uninformative. Continuing to fine-tune on these patterns may offer limited benefit and even degrade downstream task performance. In this paper, we investigate token quality from a noisy-label perspective and propose a generic token cleaning pipeline for SFT tasks. Our method filters out uninformative tokens while preserving those carrying key task-specific information. Specifically, we first evaluate token quality by examining the influence of model updates on each token, then apply a threshold-based separation. The token influence can be measured in a single pass with a fixed reference model or iteratively with self-evolving reference models. The benefits and limitations of both methods are analyzed theoretically by error upper bounds. Extensive experiments show that our framework consistently improves performance across multiple downstream tasks.

Dreame is making a splash at CES this year with a new pool cleaner that's smart enough to gauge the shape of your pool before it dives in for a cleaning, along with a robot vacuum with retractable, obstacle-climbing legs. Slated to ship in March, the Z1 Pro robotic pool cleaner boasts Dreame's PoolSense technology, which intelligently recognizes pool shapes and adjusts its cleaning strategy for optimal results. With 8,000 GPH suction power and dual brush technology, the Z1 Pro promises thorough cleaning, removing debris from floors, walls, and waterlines. The Z1 Pro's LiFi Control System utilizes optical communication to offer precise control over cleaning patterns and paths. Dreame says its horizontal waterline cleaning technology is now 50 percent more efficient than in previous models, while the Auto Poolside Parking feature simplifies retrieval.

Robot vacuums have become indispensable in our homes. From pet hair to daily dust, these devices keep floors clean with minimal hands-on help. But like any tool, a robot vacuum needs regular upkeep to keep running at peak performance--and to avoid early retirement. Fortunately, the steps to extending your vacuum's lifespan are simple, and many are directly recommended by manufacturers. Here's what you need to know to get the most out of your robo-cleaner.

So you thought your new robot vacuum with its self-emptying bin and LiDAR navigation was state of the art? Robot vacuum technology has grown by leaps and bounds over the past year alone. Besides simply emptying their own bins and mapping your rooms with lasers (that's so 2022), the latest robot vacuums can hoist themselves over door thresholds, extend robotic arms to reach dust particles tucked in corners, apply elbow grease to stubborn floor stains, and more. Ever watch your robot vacuum struggle to crest a door threshold that's barely an inch tall? It's a sad sight, not to mention a barrier (literally) to achieving total vacuum coverage for your floors.

Pet owners know keeping fur from collecting in corners, couch crevices, and our clothes is a Sisyphean task, but a robot vacuum for pet hair can help. It doesn't matter if scritch sessions end in a handful of Himalayan or husky; our fate is to vacuum again and again, forever. But that kind of menial, repetitive task can easily be outsourced to a robot vacuum that will never tire--even during seasonal shedding. Since their debut, robot vacuums have gotten smarter, stronger, and added a bunch of bells and whistles like scheduling, hands-free emptying, and mops so you can delegate more cleaning tasks (all featured in our best overall pick, the ECOVACS Deebot T30S Combo). Here's our guide to finding the best robot vacuums for pet hair so that you can spend more time with your furry friend(s) and less worrying about the floors.

When it comes to robot vacuums, sheer suction power isn't the only factor that determines a vacuum's effectiveness. Navigation, battery life, and additional features also play crucial roles in how well a robot vacuum performs. That said, the best robot navigation systems in the world won't do much good if the vacuum can't bust the dust it discovered. Strong suction makes a huge difference in cleaning performance, especially when tackling heavy debris and deep-set dirt in carpets. In this roundup, we'll tick off five of the most powerful robot vacuums we've ever seen, each of which boasts an impressive "Pa" rating while also bringing other essential features to the table.
