Automatic sleep staging typically relies on gold-standard EEG setups, which are accurate but obtrusive and impractical for everyday use outside sleep laboratories. This limits applicability in real-world settings, such as home environments, where continuous, long-term monitoring is needed. Detecting sleep onset is particularly relevant, enabling consumer applications (e.g. automatically pausing media playback when the user falls asleep). Recent research has shown correlations between in-ear EEG and full-scalp EEG for various phenomena, suggesting wearable, in-ear devices could allow unobtrusive sleep monitoring. We investigated the feasibility of using single-channel in-ear electrophysiological (ExG) signals for automatic sleep staging in a wearable device by conducting a sleep study with 11 participants (mean age: 24), using a custom earpiece with a dry eartip electrode (Dätwyler SoftPulse) as a measurement electrode in one ear and a reference in the other. Ground truth sleep stages were obtained from an Apple Watch Ultra, validated for sleep staging. Our system achieved 90.5% accuracy for binary sleep detection (Awake vs. Asleep) and 65.1% accuracy for four-class staging (Awake, REM, Core, Deep) using leave-one-subject-out validation. These findings demonstrate the potential of in-ear electrodes as a low-effort, comfortable approach to sleep monitoring, with applications such as stopping podcasts when users fall asleep.

Federated learning (FL) enables building robust and generalizable AI models by leveraging diverse datasets from multiple collaborators without centralizing the data. We created NVIDIA FLARE as an open-source software development kit (SDK) to make it easier for data scientists to use FL in their research and real-world applications. The SDK includes solutions for state-of-the-art FL algorithms and federated machine learning approaches, which facilitate building workflows for distributed learning across enterprises and enable platform developers to create a secure, privacy-preserving offering for multiparty collaboration utilizing homomorphic encryption or differential privacy. The SDK is a lightweight, flexible, and scalable Python package. It allows researchers to apply their data science workflows in any training libraries (PyTorch, TensorFlow, XGBoost, or even NumPy) in real-world FL settings. This paper introduces the key design principles of NVFlare and illustrates some use cases (e.g., COVID analysis) with customizable FL workflows that implement different privacy-preserving algorithms. Code is available at https://github.com/NVIDIA/NVFlare.

Behind the scenes, the same call automatically and invisibly decides whether a machine learning classifier is reliable enough to classify the example on its own, or whether human intervention is needed. Models get built automatically, they're continually retrained, and the caller never has to worry whether more data is needed. In the rest of this article, we'll go into more detail on the problems we described above--problems that are common to all efforts to deploy machine learning to solve real-world problems. In order to train any spam classifier, you'll first need a training set of "spam" and "not spam" labels.

To solve real-world problems with AI, a deep learning system would need to be trained on a trillion parameters in 20 minutes. Even Intel is willing to admit that computers are great at crunching numbers, but not so great that they also make good decision-makers. Based on a recent webinar about the hardware advancements that have made better artificial intelligence (AI) possible, and what the future holds, that is about to change, and much faster than many would believe. Pradeep Dubey, the director of the Parallel Computing Lab at Intel, explained the difference between traditional AI systems and newer implementations like deep learning--primarily, it's about who is making the rules. In traditional AI, humans have to create rule-based systems for understanding which data should be processed, and how.

If you miss the days of playing Pong with old-school dial controllers but would rather not track down a vintage console or arcade cabinet, today's your lucky day. Daniel Perdomo and crew have built a real-world Pong machine that replicates the pioneering game with physical parts. Despite what it looks like, it's not just an Atari-themed air hockey table. All the eccentricities of Pong gameplay are intact, just in a more tangible (and arguably, far more immersive) form. LEDs track the score, while the controllers are rejiggered hard drives.
