Facilitating user actions between a media playback device and a separate personal device (e.g., a smartphone, smart watch, or wearable device) can present challenges. For example, methods that rely on shared user accounts may be less suitable for public or shared displays, while others, such as those using visual codes, can involve user actions that might interrupt a passive viewing experience. A data payload, such as a product identifier, can be embedded as an acoustic watermark into an audio signal broadcast from a source device. A separate receiving device can use its microphone to passively detect and decode this watermark …

System For Epistemologically-Informed Text Generation With Language Models, Kenneth Steimel, Aman Sardana, Scott Dozier

Defensive Publications Series

Proposed herein is a system that enables Large Language Models (LLMs) to automatically generate linguistically appropriate hedging language that accurately reflects the reliability of underlying information sources. By extracting multi-dimensional epistemological metadata (source authority, temporal relevance, evidential support) from knowledge base documents and integrating this metadata directly into LLM generation processes through augmented attention mechanisms, the system produces responses where confidence expressions match actual source reliability. The approach addresses the "confidently incorrect" problem in high-stakes applications (medical, legal, financial) by ensuring LLMs communicate uncertainty appropriately, using domain-specific hedging conventions and continuous feedback-driven refinement.
