LGM: Teaching AI to Untangle Confusing Concepts

When instructions use ambiguous or mismatched terms, even smart LLMs can stumble. A new approach, the Language Graph Model (LGM), helps models clarify what users mean by mapping how concepts relate.

Inheritance: recognizing "a robin is a bird"—a family tree of ideas.
Alias: spotting different names for the same thing, like "NYC" and "New York City".
Composition: understanding whole-part links, like "car" includes "engine".

LGM extracts these meta-relations from natural language, then uses a reflection step to double-check them. A Concept Iterative Retrieval algorithm feeds the most relevant relations and descriptions to the LLM right when it answers.

Unlike typical Retrieval-Augmented Generation that stuffs long passages into the context window, LGM can handle texts of any length without truncation by pulling only the right pieces as needed.

Takeaway: clearer concepts in, more accurate answers out—and consistent gains over common RAG baselines on standard benchmarks.

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)
