Beyond Shortest Path: Routes That Understand You

GPS apps nail the fastest route, but miss real-life context: pick up meds, avoid school zones, or grab a coffee before it closes.

PAVe (Personalized Agentic Vehicular Routing) adds that missing layer. It pairs proven pathfinding with an AI agent that understands your tasks and preferences. First, it computes candidate routes using a multi-objective Dijkstra (time and CO2). Then an LLM reasons over your instructions and a city POI cache to choose and tweak the best route.

“Pick up prescription, then daycare, avoid tolls.”
“Find an EV charger with minimal detour.”
“Drive-thru stop before 9 pm.”

In realistic urban tests, PAVe aligned complex intent with route changes, hitting over 88% accuracy in initial picks using a local model.

Takeaway: blending classical routing with semantic reasoning can deliver personalized, adaptive navigation at scale.

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)
