Can a general-purpose time‑series AI learn brainwaves? This study tests a recent foundation model on electroencephalography (EEG) tasks like motor imagery (for brain–computer interfaces) and sleep stage prediction.

Pretrained on diverse, non‑EEG real‑world time series
Or pretrained entirely on synthetic signals
Then fine‑tuned for EEG tasks

Results: Both routes delivered strong performance, outperforming EEGNet (a popular CNN baseline) and CBraMod (a specialized EEG foundation model).

Why it matters: Cross‑domain pretraining—even without neural data—can transfer effectively to EEG. This could speed up brain-signal applications and reduce reliance on large labeled EEG datasets.

Automating GDPR Compliance: A Roadmap for Companies and Law Firms

GDPR compliance is more than checkboxes. A new roadmap from the Privatech project shows how automation and machine learning can help companies and law firms assess—and even generate—privacy compliance. * Shift the focus to data processors’ real workflows: drafting policies, mapping data uses, documenting decisions. * Break compliance into machine-ready

FPGAs for Faster, Leaner Deep Learning: A Review of CNN Accelerators

Deep learning drives image search, robots, and medical scans. Most systems lean on CPUs and GPUs. This review asks: what if we run convolutional neural networks (CNNs) on FPGAs—reconfigurable chips you can tailor to the model? * Why FPGAs: custom dataflows, low latency, and strong energy efficiency—great for cameras,

Dynamic-K: Recommendations That Know When to Stop

Most apps show a fixed number of “top” items—say 10 movies or 20 products—assuming there are always enough good options. But that’s not always true: sometimes there are few relevant items, or some users are extra picky. The result? Filler recommendations. Dynamic-K flips the script. Instead of

Teaching chatbots to stop contradicting themselves (DECODE)

Teaching chatbots to stop contradicting themselves Ever had a bot say one thing, then the opposite a few turns later? This study introduces DECODE—a new task and dataset for spotting contradictions in everyday conversations, drawn from both human-human and human-bot chats. * New data beats existing natural language inference (NLI)
